Description

Detergent products, methods and manufacturing.

Technical field

The present invention relates to the field of dishwashing, in particular refers to the use of a bag water soluble multicompartmental adapted to fit in the dishwasher dispenser and to supply product to the wash main and / or cycles after dishwasher rinse. The bag contains a cleaning composition that is released when it It produces the dissolution of the bag.

Background of the invention

Some consumers have observed that the doses Dishwasher detergent units are more attractive and comfortable because they avoid the need for the consumer to measure the product, thus giving rise to a more precise dosage and avoiding the waste of overdosing or insufficient dosage. For this reason, dishwashing detergent products in Pill form have become very popular. The products Bag-shaped detergents are also known in the art, they also have the advantage over the pads to avoid contact of the consumer's fingers with the composition for washing dishes that may contain bleach and / or other substances irritating

The process for automatic dishwashing usually involves an initial prewash cycle, a cycle of main wash and several hot rinse cycles. Be they get better results when the detergent is released at start of the main wash cycle than when the detergent is released in the prewash cycle since this can be lost with The initial water. In washing machines for washing clothes, the detergent can be placed in the drum or in the dispenser, without However, in the dishwasher the detergent is usually released in the main wash through the dispenser to avoid premature dissolution in prewash. The amount of detergent It is therefore limited by the volume of the dispenser. The Dispensers vary in volume and shape between different Manufacturers In the case of loose detergent (i.e. powders, paste and liquids), the volume of the dispenser is a factor decisive. In the case of unit dose forms, such as a tablet, the geometry and shape of the dispenser also play a very important role.

The pads can be designed to have a size and shape that fit all dishwashers. One of the disadvantages of detergent tablets is the fact that its manufacturing process requires the additional stage of powder compaction. This stage reduces the enzymatic activity and slows the dissolution rate of the ingredients that make up the tablet, or requires the use of systems complex and expensive disintegrants or it is difficult to achieve differential dissolution of the active ingredients of the Detergent.

Some detergent components used in detergent compositions for dishwashing are liquids It may be difficult or expensive to include these ingredients liquids in a solid detergent composition. Thus, certain ingredients are preferably transported and supply detergent manufacturers in liquid form, additional processing steps are required, and sometimes also expensive, to be able to include them in a detergent composition solid. An example of these detergent ingredients is the surfactant, especially the nonionic surfactant, which is of typical liquid form at room temperature or is transported and typically supplies detergent manufacturers in the form liquid Another example is organic solvents.

Current methods to incorporate liquid ingredient in solid detergent compositions include the absorption of the liquid ingredient in a vehicle solid, for example, by mixing, agglomeration or pulverized Typically, solid detergent compositions they comprise only small amounts of these ingredients liquid detergents due to the difficulty and the cost of incorporating These liquid ingredients in a solid detergent. Besides, the incorporation of liquid ingredients in the compositions solid detergents can affect the characteristics of dissolution of the composition (for example, as a result of the formation of the surfactant gel phases), can increase the moisture absorption by water sensitive ingredients and can also cause fluency problems. It would be advantageous to have a detergent composition that would allow different Ingredients be in their natural state, that is, liquid or solid.  This would facilitate the manufacturing process, increase the component stability and would also allow the release of liquid ingredients before or after the release of solid ingredients For example, the differential dissolution of active ingredients would be beneficial in the case of compositions of enzyme / bleach to prevent oxidation of enzymes by the bleach in the dishwashing solution. Too it would be advantageous to separate the bleach from the perfume.

Another factor that can contribute to liberation ineffective of the active substances to the wash solution, in the case of the pills, it is the need to add materials vehicle, such as porous materials capable of joining active liquid materials, binders and disintegrants. In in particular, the incorporation of surfactant liquids into detergent compositions in powder form may cause considerable processing difficulties and also the problem of a bad dissolution due to the formation of phases of gel surfactant.

Multicompartmental exchanges that have a compartment comprising a liquid composition are described in WO 01/85 898, WO 01/83 637, WO 01/83 667 and EP-A-1 126 070. All these Documents are considered as the state of the art under Art. 54 (3) EPC. EP0593952 describes bags for use in automatic dishwashers

There is still a need for a multicompartmental unit dose form capable of adapting to the dispensers of different types of dishwashers and that allow the simultaneous release of incompatible ingredients and Ingredients in different physical forms. There is also the need for a simplified manufacturing process to manufacture a multi-compartment and bag-making bag multi-compartment with resistance characteristics, improved handling and dissolution, as well as an aesthetic Excellent.

The most common procedure for the production of water-soluble bags with products, such as products from cleaning, is the so-called process of filling-sealing in vertical mold. Through this one, a vertical tube is formed by folding a film. The extreme The bottom of the tube is sealed forming an open bag. This bag is partially filled leaving an upper space where the upper part of the open bag is subsequently sealed between yes to close the bag and lead to the next open bag. The First bag is then cut and the process is repeated. The bags formed in this way are usually shaped like a pillow.

A second known procedure for bag production is using a matrix that has a series of molds and forming from a film open bags in these molds, which are then filled and sealed. This method uses the film-shaped material more effectively and the process has more flexibility in terms of bag forms and ingredients used. However, the procedure has a limited suitability for industrial application, because it cannot produce large quantities of bags (per unit of time) of one easy and effective way.

A third proposed process is the formation of bags in molds present on the surface of a drum circular. Through this process, a film is circulated through the drum and bags are formed, which pass below A filling machine that fills the open bags. Filling and the sealing has to take place at the highest (highest) point of the circle described by the drum, p. e.g., typically filling is done just before the rotating drum starts the circular movement down and the sealing is done just after the drum starts its downward movement.

A problem associated with the filling machine vertical is that the process is not very effective: the process is intermittent and very slow, for example due to changes in process speed between one stage and the next, and each stage bag formation typically produces only one row of bags in one dimension; so, only one amount can be formed Limited bags per minute. In addition, large are used quantities of film per dose of product because the method does not allows the complete filling of the bags and there is a gasket considerable along the vertical dimension of each bag and the method does not allow the stretching of the film. In addition, it does not exist a lot of flexibility regarding the shapes of the bags conformed.

The problems associated with the second procedure which uses a matrix with molds also include the fact that the process is intermittent (or an indexing process) and that the process is slow and implies accelerations and decelerations, the which reduce the overall speed and also causes the spill of the Product from open bags. Therefore, the performance of This process is not very high (per unit of time).

The circular drum process overcomes some of the disadvantages of these procedures because it does not allow changes of speed (no acceleration / deceleration) and can easily provide bags arranged in two dimensions and the Bag shape may vary to some extent. However the Spill from the bags can be quite important, due to the circular movement, which causes the product to be poured into the sealing area and this causes problems with sealing (leakage joints). Therefore, the process does not allow bags fill up completely because the spill is all a trouble. Thus, this procedure has even more problems. important when used for liquid products, which have more likely to cause a major stroke due to circular movement. In addition, filling and sealing has to be made around the highest point of the circular path of the drum, thus greatly reducing the overall speed and the performance of the bag formation process.

All known processes are also designed primarily to manufacture bags with a single compartment There is still a need for a procedure to manufacture water-soluble multicompartmental bags that solve the aforementioned problems, specifically of a continuous procedure with a fast production speed and that minimizes the amount of film used for each bag. There is also a need for a manufacturing process for water-soluble multicompartmental bags with a resistance enhanced and adapted for use in the automatic dishwasher.

Summary of the invention

According to the present invention, a method of washing dishes, cutlery and glassware in a dishwasher using a dishwashing product in Water soluble bag form. The bag comprises a plurality of compartments in generally overlapping relationship or superimposable, for example, the plurality of compartments can be arranged symmetrically, one above the other, one next to other (so that they can be folded and overlapping) or with any other suitable arrangement provided that the compartments are superimposable during use. Each compartment contains one or more active detergent components or detergent auxiliaries and at less a compartment comprises a liquid composition. The bags  Water soluble comprising a plurality of compartments are defined here as multicompartmental exchanges. The bags multicompartmentals in which the compartments are in a Overlapping relationship are especially advantageous when one or more of the compartments comprise an ingredient sensitive to moisture, since the compartment comprising an ingredient Moisture sensitive can be placed in an intermediate layer or lower and thus have a smaller surface area exposed to the environment surrounding, thus reducing the possibility of absorption of the humidity of the environment.

The bag preferably has a volume of 5 to 70 ml, preferably 15 to 60 ml, more preferably 18 to 57 ml, and a longitudinal / transverse dimensional relationship in the range from 2: 1 to 1: 8, preferably from 1: 1 to 1: 4. The dimension longitudinal is defined as the maximum height of the bag when the bag rests on one of the bases that has the maximum space busy with bag compartments superimposed on a longitudinal direction, that is one over another, and under a load static of approximately 19.6 N (2 kg). Cross-sectional dimension defined as the maximum width of the bag in a plane perpendicular to the longitudinal direction in them terms. These dimensions are suitable to adapt to most dishwasher dispensers. Although the form of the bag can vary a lot in order to maximize the volume available, preferred bags have the most similar basis possible to the profile of most dispensers, that is generally rectangular.

In one embodiment, the plurality of Water-soluble bag compartments is in a relationship generally superimposed and the bag comprises exterior walls upper and lower generally opposite, side walls to flange mode that make up the sides of the bag and one or more internal dividing walls that separate the different compartments each other, and where each of said outer walls upper and lower and the side wall as a flange are conformed by thermoforming, vacuum forming or a combination thereof.

In a preferred embodiment each wall internal division of the water-soluble multicompartmental bag is attached to an outer or side wall of the bag along a single sealing line or both to the outer wall and to the side wall of the bag along a plurality of lines of sealed that at least partially do not overlap. Preferably each dividing wall is attached to one or more exterior walls or lateral by heat sealing or sealing with solvents.

In especially preferred embodiments, such as minimum one internal dividing wall of the multicompartmental bag is fixed to an upper or lower outer wall along a first continuous sealing line and one or both of said outer walls and said dividing wall are fixed to the side wall as a flange along a second line of continuous sealing, and where the sealing lines in the case of heat sealing are essentially not superimposed and in the case of solvent sealed, at least partially they are not overlapping

The non-overlapping sealing lines are especially advantageous in the case of multi-compartment bags manufactured using a procedure that involves several stages of Heat sealing not simultaneous. Without imposing any theory, it is believed that the sealing mechanism involves the stage of water evaporation of the film, therefore it is very difficult to get a good sealing superimposed unless two seals are formed simultaneously. Heat sealing is preferred in cases where which bags are filled with water sensitive components. Solvent sealing can reduce the cost of processing, It can reinforce the joints and can speed up the process. The boards partially non-overlapping allow the superposition of a plurality of compartments of different sizes.

Preferably, at least one dividing wall Internal multi-compartment bag is attached to the wall upper exterior along a first joint line that defines the waistline of the wall as a flange and where the second board not overlapping or at least partially not superimposed is preferably below inward of the joint line that defines the waistline in the direction of the lower outer wall. The side wall as a flange also is slightly collected or gathered in the final bag to Provide a mattress type look.

In another embodiment, the water soluble bag comprises a plurality of compartments in a relationship side-by-side although generally superimposable (for example, the compartments can be folded one on top of another). The bag comprises upper outer walls and generally opposite bottoms, one or more side walls to flange mode and one or more external partition walls, and where each of said upper and lower outer walls and said flange side walls are formed by thermoforming, vacuum forming or a combination of same.

In one embodiment, at least one of the plurality of water soluble bag compartments comprises a powder or densified powder composition. The composition in powder usually comprises traditional solid materials used in dishwashing detergent, such as detergency builders, alkalinity sources, enzymes, bleach, etc. The powder composition can be in dry powder form, hydrated powder, agglomerates, materials encapsulated, extruded, pills or mixtures thereof. Too It is useful to have water-soluble bags with several compartments that They comprise different powder compositions, usually compositions in different compartments comprising substances  active or incompatible active substances that need to be released at different times in the process of washing crockery It is advantageous to have bleach and enzymes in Different compartments

       \ global \ parskip0.850000 \ baselineskip
    

In a preferred embodiment, at least one of The powder compartments comprise bleach in the form of particles The bleach is preferably selected from inorganic peroxides, including perborates and percarbonates, organic peracids, including monoperoxy carboxylic acids previously formed, such as peroxy phthaloyl amido acid hexanoic, and diacyl peroxides.

In the case of powder compositions you can obtain a differential solution, for example, varying the degree of dust compression and / or particle size of the powder compositions in the same or in different compartments Another way to get the differential solution is use water soluble films of different thickness or with a percentage of different solubility in the conditions of use. The film solubility can be controlled by for example, pH, temperature, ionic strength or by any other means, medium. In the processes in which you want to achieve liberation by phases or sequential of the active detergent substances, prefers that each of the compartments of the bag has a percentage of disintegration or dissolution profile different in terms of use.

At least one of the plurality of Water soluble bag compartments comprises a composition liquid Liquid compositions comprise liquid materials traditional used in detergents for washing tableware, such as non-ionic surfactants or solvents organics described later herein. In preferred embodiments, the liquid composition comprises enzymes of detergency. Soluble bags are especially useful in water that have a compartment comprising a composition liquid and another compartment comprising a solid composition. In the case of liquid compositions, especially liquid compositions included in a secondary container, is desirable that the composition has a water content similar to water content of the film in order to avoid the water transfer between one and the other. In cases where the water content is lower in the composition than in the film, the water can migrate from the film to the composition making the water soluble bag becomes brittle. Because reasons similar, it is also desirable to have a similar amount of plasticizer in the composition and in the film.

In another embodiment, at least one of the plurality of water soluble bag compartments comprises A composition in the form of a paste. The bags multicompartmentals may also include compositions in form of gel or wax.

In preferred embodiments, at least one of the plurality of water soluble bag compositions comprises an organic solvent system compatible with the bag soluble in water. The organic solvent system can act simply as a liquid vehicle, but in compositions preferred, the solvent can help remove dirt after bake, bake or burn and therefore the detergent has functionality by itself. The organic solvent system (which comprises a single solvent compound or a mixture of compounds solvents) preferably has a component content organic volatile above 133.3 Pa (1 mm Hg) and more preferably above 13.3 Pa (0.1 mm Hg) of less than about 50%, preferably less than about 20% and more preferably less than about 10%, by weight of the solvent system. In the present report the content of volatile organic components of the solvent system is defined as the content of organic components in the solvent system which has a vapor pressure greater than the prescribed limit at 25 ° C and atmospheric pressure.

The organic solvent system for use in the present invention is preferably selected from solvents of organoamine, including alkanolamines, alkylamines, alkyleneamines and mixtures thereof; alcoholic solvents including alcohols aromatic, aliphatic (preferably C 4 -C 10) and cycloaliphatics and mixtures of the same; glycols and glycol derivatives including (poly-) alkylene C 2 -C 3 glycols, glycol ethers, esters of glycol and mixtures thereof; and selected mixtures of Organoamine solvents, alcoholic solvents, glycols and glycol derivatives. In a preferred embodiment the solvent organic comprises organic amine solvent (especially alkanolamine) and glycol ether type solvent, preferably in a weight ratio of about 3: 1 to about 1: 3 and wherein the glycol ether type solvent is selected from ethylene glycol monobutyl ether, monobutyl ether of diethylene glycol, ethylene glycol monomethyl ether, monoethyl ether ethylene glycol, diethylene glycol monomethyl ether, ether diethylene glycol monoethyl, propylene glycol monobutyl ether and mixtures thereof. Preferably, the glycol ether is a mixture of diethylene glycol monobutyl ether and butyl ether of propylene glycol, especially in a weight ratio of about 1: 2 to about 2: 1.

In the present invention a method of washing dishes, cutlery and glassware in a dishwasher using the product for dishwashing described herein. The method is suitable for the simultaneous or consecutive supply of active substances detergents at one or more of the main wash cycles or rinse the washing machine.

The process to make the bags for use in the present invention it comprises the steps of: i) forming a first moving band of full bags and optionally sealable couplings releasably coupled on a first surface endless in motion (preferably rotary); ii) form a second band in motion of full and sealed bags releasably coupled on a second endless surface in movement (preferably rotary); iii) overlap and seal or fixing said first and said second movable bands to form a superimposed and sealed band; and iv) separate said band superimposed and sealed in a plurality of soluble bags in multi-compartment water. Preferably, the second surface endless moving moves synchronously with said First endless surface in motion. This facilitates the realization of the process in a continuous way.

       \ global \ parskip1.000000 \ baselineskip
    

The first band of full open bags is You can close with any means for closing bands, as per example a film of material for forming bags, although in a preferred embodiment it is preferably closed with the second band of bags, which avoids the use of a layer or film additional. The means for closing bands preferably moves synchronously with the first endless surface and the first band of open bags mounted on it. Preferably the second band of bags is reversed before closing of the first band of open bags, preferring this from the point of view of facilitating overlap in the process of sealing of the band.

The first band in movement of bags open can be formed, for example, by incorporating a movie Water soluble to a matrix that has a series of molds. The molds can have any suitable size and shape, being preferred for use in the present invention molds rectangles that have a suitable profile to fit the Most dishwasher dispensers. Apart from having the advantage of adapting to the dispenser, rectangular bags they have inherently regions with a different film thickness and this can contribute to improving the dissolution profile of the bag.

Open bags can be shaped using thermoforming, for example, by heating the molds or applying heat by any other known method, such as blowing hot air or using heat lamps. If desired, empty can be used to insert the film into the mold. Open bags can be formed alternately by vacuum forming, in which case heat can be added to facilitate the process. In general, thermoforming consists fundamentally in a process of plastic deformation while vacuum forming is fundamentally a deformation process elastic The two techniques can be combined to produce bags with any desired degree of elasticity / plasticity.

The first band of open bags is formed preferably on a first endless surface in rotation, this surface being in a preferably horizontal position or basically horizontal during the filling of the bag.

A preferred process comprises the steps of conformation and filling of a horizontal band or basically horizontal moving open bags mounted so that it they can separate on a first endless surface in motion and the closed band of open bags with a band on superimposed movement of preformed bags, filled and sealed that moves synchronously with it. The first endless surface preferably moves in a continuous horizontal or basically horizontal movement and preferably in a continuous horizontal rectilinear motion during the filling stage of the first moving band of open bags

Preferably the first open band of open bags are filled by a filling station of product comprising means for filling quantities of a or more product feed streams in each of the open bags Preferably this filling station is arranged so that it moves synchronously with the first band of open bags during the filling stage, so which avoids any acceleration / deceleration of the bags open during filling and the subsequent pouring of detergent and contamination of the sealing area. Horizontal movement rectilinear of the first band of open bags allows the total or more complete filling of the open bags with what Get a better use of the film. So Alternatively, the filling station can be stationary.

The detergent product can be dispensed in each of the open bags through devices individual dosing or dispensing devices that have a single feeder or means to supply a single current of product feed, this being preferred in cases where that you have to release a single premixed composition in the bag. In the case of liquid compositions multi-component, each bag can be filled through multiple feeders or means to supply a plurality of product feed streams, where each feeder supplies a liquid composition (or component of the same) different, so as to avoid the need for a premixed stage. In the case of powder compositions multi-component, again each bag can be filled by multiple feeders, where each of them supplies a powder composition (or component thereof) so that it They form different layers of product. In the case of compositions in dust, it is an advantage to have a screen-like tape that has a hole of the same size or slightly smaller than the open bag opening in order to avoid contamination of the board.

The first band of open bags can be optionally close and seal with a film after filling and before overlapping and sealing the second band of bags in motion. The second band of bags can be manufacture separately but in preferred embodiments the second band of bags is placed horizontally or basically horizontally during the filling of the bags. In a preferred procedure the stage of filling the second band Horizontal moving open bags is done using a second filling station of the product that moves so synchronized with the second endless surface. In a procedure, the filling station comprises means for release of a plurality of feed streams from product, as in the case of the filling station for the first band of open bags described above in the present memory When the first band itself is sealed with the film before superimposing the two bands, it may be required that the two bands are fixed to each other along a sealing line discontinuous

       \ newpage
    

Although each of the first and second endless surfaces and the corresponding band of bags can be adapt for a horizontal, rectilinear or curvilinear during the filling of the bags, in the present invention a method is preferred wherein the first endless surface moves following a horizontal movement rectilinear during the filling stage of the first bag band open in motion and where the second endless surface is moves following a basically horizontal rectilinear movement or curvilinear during the filling stage of the second band in Open bag movement.

Preferably the second endless surface rotates in a direction opposite to that of the first surface without finish.

The second band bags are also cover, close and seal preferably with a type closure film after filling and before overlapping on the First band of bags and the sealing of the two bands. Of use Preferred in the present invention is heat sealing, which is can be done by any known means, for example, by direct application, infrared, ultrasonic radiation, radiofrequency, laser. Solvent sealing can be used alternatively in the present invention.

The two compartment bag band formed in this way it is then divided into individual bags, by example, by known cutting methods. Preferably, the bags are produced at a constant rate and at a speed constant, which can facilitate the automation of the process packing. Although the procedure described above in the This report refers to the manufacture of two bags compartments, multi-compartment bags can be manufactured with more than two compartments in a similar way, for example, superimposing and sealing three or more bands of bags. They are also very useful for use in the present invention the bags multicompartmentals in which at least one of the compartments is horizontally divided into a plurality of compartments

       \ vskip1.000000 \ baselineskip
    

Another process to make the bags for your Use in the present invention comprises the steps of:

to)

conform and partially fill a moving band of open bags mounted so that they can separate on an endless surface in motion, being partial filling so that enough space is left for the formation of a second compartment in it mold;

b)

close and seal said band in movement with a means to close bands that moves so synchronized with it, where the means to close bands is enter partially filled bags so that it forms a plurality of closed and overlapping compartments open;

C)

fill, close and seal the open compartments superimposed by a second means of closure of the band that moves synchronously with said moving band; Y

d)

separating said band into a plurality of water soluble multicompartmental bags.

       \ vskip1.000000 \ baselineskip
    

In the previous process the formation of bags multicompartmental requires only an endless surface in movement, which can be beneficial from the point of view economic. Each bag is formed in a unique mold. After form the band of open bags, each open bag is filled partially, it is closed and sealed giving rise to a second open compartment, which is then filled, closed and seal. In a preferred embodiment the sealing steps are performed by sealing with solvent.

The term "filling" herein includes both "partial" and "complete" filling of a bag or a compartment thereof. A bag or a Open compartment is considered to have been completely filled when the product fills at least approximately 90% of the volume of the bag or open compartment. Filling "partial" is done correspondingly.

       \ vskip1.000000 \ baselineskip
    

A slightly modified version of this process comprises the stages of:

to)

conform and partially fill a moving band of open bags mounted so that they can separate on an endless surface in motion;

b)

close said moving band with a means to close bands that moves synchronously with the same, where the means to close bands is introduced into the bags partially filled so that a plurality of closed compartments and open overlays;

C)

fill and close the compartments overlays open by a second closure of the band that moves synchronously with said moving band;

d)

seal said band and said first and second band closure means; Y

and)

separating said band into a plurality of water soluble multicompartmental bags.

       \ vskip1.000000 \ baselineskip
    

In a preferred embodiment of this process, the sealing stage is done by sealing ultrasonic.

In another variation of this method, the band of open bags of stage (a) is filled, partially or completely, with a first composition comprising an active substance detergent or auxiliary and then or the composition is densifies or the bag enlarges to provide enough space for the formation of the second compartment. In the case of a powder composition, densification can be achieved by compaction, tapping, tamping, vibration, etc., performing the densification preferably so that an increase of the apparent density of at least about 5%, preferably at least about 10% and especially at least about 20%, more preferably at least approximately 30% The final apparent density is preferably at least about 0.6 g / cc, more preferably as minimum about 0.8 g / cc, more especially at least approximately 1 g / cc The means to enlarge the bag include means for altering the size or volume of the mold, for example, a section with a moving floor, a size insert or variable volume, etc.

In alternative embodiments, the Overlapping open compartments can also be formed after the stage of closing and sealing the moving band of open bags Therefore, according to another aspect of the process, provides a process to make a water soluble bag that comprises a plurality of compartments in a relationship generally superimposed or superimposable, where each one understands an active or auxiliary detergent component, comprising the process the stages of:

to)

conform and fill a band in open bag movement mounted so that you can separate on an endless surface in motion;

b)

close and seal said band in movement with a means to close bands that moves so synchronized with it so that a plurality of closed compartments;

C)

conform a cavity within some or of all closed compartments formed in step (b) of form that generates a plurality of open compartments overlaid above closed compartments;

d)

fill, close and seal the open compartments superimposed by a second means of closure of the band that moves synchronously with said moving band; Y

and)

separating said band into a plurality of water soluble multicompartmental bags.

       \ vskip1.000000 \ baselineskip
    

Again in a slightly modified version of this process, the sealing stage is carried out in one stage post process. The process includes the stages of:

to)

conform and fill a band in open bag movement mounted so that you can separate on an endless surface in motion;

b)

close said moving band with a means to close bands that moves synchronously with the same so that a plurality of compartments is formed closed

C)

conform a cavity within some or all closed compartments formed in step (b) of form that generates a plurality of open compartments overlaid above closed compartments;

d)

fill and close the compartments overlays open by a second means to close bands which moves synchronously with said band in movement;

and)

seal said band and said first and second band closure means; Y

F)

separating said band into a plurality of water soluble multicompartmental bags.

       \ vskip1.000000 \ baselineskip
    

In order to conform the cavities, the Closed compartments can undergo a compression stage or powder compaction as described above and, if it is necessary, means can be incorporated as exit holes in the band to allow the air out of the compartments tablets

In all these aspects of the process, the endless surface preferably moves following a movement horizontal or basically horizontal continuous, preferably rectilinear, during the filling stages of the open bags and open compartments superimposed on the moving band. Alternatively, the movement may be intermittent, although It is less preferred. It is also preferred that the filling steps are made using the filling station of the product that is move in sync with the endless surface. Suitably, the product filling station may comprise means for filling quantities of a plurality of product feed currents in each of said compartments

Preferably, the bags multicompartmentals formed according to any of the methods described in the present invention comprise a plurality of compartments containing a powder composition and a plurality of compartments containing a composition liquid, gel or paste. It is also understood that by using proper feeding stations it is possible manufacture multi-compartment bags that incorporate several different or differentiated powder compositions and / or compositions liquid, gel or paste different or differentiated. This can be especially valuable for the manufacture of dosage forms units that have visual effects and / or other effects new sensory.

Therefore, in another aspect of the process provides a process to form a plurality of bags multicompartmental in a multiplicity of groups sensory different, where the process includes filling each of the multiplicity of compartmental groups with the corresponding sensory different composition, where the groups The results are different in terms of color, shape, size, design or ornament, or where the groups are different in terms of provide a unique sensory signal such as smell, sound, touch, etc.

The bags of the present invention can be provided in a package comprising an outer container such as a container that allows you to see through it, for example a box of cardboard or transparent or translucent bottle containing a plurality of water-soluble bags or other unit doses of detergent product in a multitude of groups visually or of Another sensory different way. For visually different in This report indicates that the groups can be distinguished in as for shape, color, size, design, ornament, etc. Otherwise, the groups are different in terms of providing a signal Exclusive sensory like smell, sound, touch, etc.

Preferably a container of detergent for washing translucent dishes, preferably  transparent, where the number of different groups of bags or of other unit doses is at least 2, preferably as minimum of 3, more preferably at least 4 and especially at least 6 and where the number of unit doses per container it is at least about 10, preferably at least of about 16 and more preferably at least about 20. Preferably unit doses are bags multi-compartment, each compartment being by itself different visually or otherwise from the rest of the Compartments in an individual bag. Preferably, the groups of bags are different in color. In the case of bags multicompartmental, at least one group of bags has a compartment that is visually different, for example, in terms of to color, of the corresponding compartment in one or more of others groups of bags. Preferably in said embodiments, all Bag groups have at least one "common" compartment, that is, one whose appearance is the same in different groups. Preferably the visually different compartment contains a liquid, gel or paste; the common compartment contains a powder or tablet. The bags can be arranged in any way in the container, either randomly or following an order, for example, in suitable arrangements that include layers where each bag It comprises at least one compartment of a different color from that of any of the remaining compartments of the remaining bags on the same layer. The container can be made of plastic or any other material with the condition that the material is what strong enough to protect the bags during transport. This type of packaging is also very useful because the User does not need to open the container to see how many bags are left, since the bags of different colors are very easy to Identify from the outside.

Naturally, materials in the form of different film and / or films of different thicknesses for the manufacture of the first and second bands in motion, where example requires that compartments have different solubility or release characteristics.

In a preferred procedure for manufacture of the first and second bands in motion, a part of the endless surface will move continuously following a horizontal rectilinear motion until it rotates around an axis perpendicular to the direction of movement, typically approximately 180 degrees and then it will move in the opposite direction, usually again following a movement horizontal rectilinear. Eventually, the surface will rotate again until reaching its initial position. In other procedures, the surface moves for example following a curvilinear movement, for example, circular, by which at least a part of the surface is basically horizontal for a period of time Simple but finite. When used, these procedures are mainly valuable to manufacture the second band in movement.

The term "endless surface" in the This report indicates that the surface is endless in a dimension at least, preferably only in one dimension. By For example, the surface is preferably part of a tape rotary plate conveyor comprising molds as Describe below in more detail.

It may be preferred that the surface be connected to 2 or more different vacuum systems, which can provide a different negative pressure and / or provide a negative pressure over a greater or lesser period of time or during a longer or shorter duration. For example, it may be preferred that a first vacuum system provide a negative pressure so continue to the area between or along the molds / edges and that the other system only provides a vacuum for a while determined to stretch the film on the molds. For example, The empty stretch of the film on the mold can be apply only for 0.2 to 5 seconds or even 0.3 to 3 or even for 2 seconds or even 0.5 to 1.5 seconds, once The film is on the horizontal part of the surface. This empty it may preferably be such that it provides a pressure negative between -10 kPa (-100 mbar) and -100 kPa (-1000 mbar), or even between -20 kPa (-200 mbar) and -60 kPa (-600 mbar).

It may be preferred that the surface or plates, including mold areas, are made of aluminum, preferably mixed with nickel or optionally that only the outer layers comprise nickel and / or mixtures of nickel and aluminum.

Preferably, at least the top layer between and / or in the surface molds is of a material resilient deformable, preferably at least the top layer Between the molds The material is typically such that has a coefficient of friction of 0.1 or more, preferably of 0.3 or more For example, the top layer between the molds, and even in the molds, it can be made of rubber, silicon material or  Cork, preferably rubber or silicon rubber. I also know prefer that the material is not too hard, for example, similar to silicone rubber that has a Shore hardness value of 10 to 90

The molds can have any shape, length, width and depth, depending on the dimensions required of the bags. If molds are desired on each surface They can also vary from each other in size and shape. By For example, it may be preferred that the volume of the final bags be between 5 and 300 ml, even 10 to 150 ml, even 20 to 100 ml or even up to 80 ml and mold sizes fit adequately.

The incorporation of the film to, and of form typical inside or on top of the surface and preferably on the horizontal part of it is made of continuously and so typically with a constant speed at throughout the process This can be done by any method. known, preferably by using rollers from which the film is unwound. The film can be transported from the rollers to the surface by any means, by example, guided by a tape, preferably a resilient tape deformable, for example, a rubber band or silicone material, including silicone rubber. The material is typically such that it has a coefficient of friction of 0.1 or more, preferably 0.3 or more.

It may be preferred that the rollers rewind the film with a speed of at least 100 m / min, even 120 to 700 m / min, even 150 to 500 m / min or even 250 to 400 m / min

Once on the surface, the film will can hold in position, p. e.g., fixed or fixed on the surface by any means. For example, the movie is can clamp with jaws or clips on the edge of the surface, where there are no molds, or press them with rollers on the surface edges, where there are no molds, fasten them with a tape on the edges of the surface, where they do not exist molds

To facilitate handling and film positioning, to achieve greater accuracy and better reliability in alignment and in order not to lose too much of the surface of the film (i.e. placed on or on the jaws, clips, rollers or tape) and also in order to reduce tension on the film or ensure more tension homogeneous about the film, it is preferred to keep the film in its position by applying vacuum on the film, stretching or pushing the film in a fixed position on the surface. Typically this is done by applying vacuum (or negative pressure) over the entire surface to be fasten to the film, for example, under the film. This method is also suitable even if the width of the film is greater than the surface, so that this system is more flexible that the use of jaws or clips.

Preferably, the vacuum is applied along of the edges of the film and, thus, typically at the edges of the film and / or on the surface between or around the molds, typically along the edges of the molds. It preferred apply the vacuum (at least) along the edges of the surface.

Preferably, said surface comprises holes that are connected to a device that can provide a vacuum, as is known in the state of the art, or the so-called vacuum chamber (s) Thus, the surface preferably has holes along the edges of the surface and / or holes along or between the molds.

It is preferred that the holes be small, preferably with a diameter of 0.1 mm to 20 mm, even 0.2 to 10 mm, even 0.5 to 7 mm or even 1 to 5 mm.

Preferably, at least some of the holes are near the edges of the mold to reduce the wrinkle formation in the area around the edges of the mold which, in a preferred embodiment of the present invention, serve as a closing or sealing zone; preferably the distance between the edge of the mold and the edge of the first hole or hole closest is 0.25 to 20 mm from the edge of the mold, or even preferably 0.5 to 5 mm or even 1 to 2 mm.

It is preferred that rows of holes along the edge of the surface and / or along the mold edge; it may be preferred that 2 or 3 or more are present rows of holes.

The use of many small holes in the way described above guarantees a more homogeneous voltage of the film and this reduces the tension required to fix the film and this improves the fixation and reduces the possibility of the film It wrinkles.

The use of a vacuum system to fix the film in its position is especially beneficial when the film is then stretched on the molds by applying vacuum such as described below.

Open bags can be formed in the molds by any method and, as described Previously, preferred methods include the use of (as minimum) a vacuum or negative pressure system to stretch the film about the molds. Preferred methods (also) include heating and / or wetting the film to make it is more flexible or even more stretched and takes the form of the mold; preferably combined with vacuum application on the film to introduce the film into the molds, or combinations of all these methods.

At least the present invention is preferred use empty In the case of bags comprising powders it is advantageous to perforate the film for several reasons: first, to reduce the possibility of defects in the film during formation of the bag, for example, defects in the movie that cause the movie to break if the movie stretches too quickly, secondly, allow the release of any gas derived from the product included in the bag, such as oxygen formed in the case of dusts which contain bleach, and thirdly, allow release Continued perfume. When heat and / or also used humidification, this can be used before, during or after use vacuum, preferably during or after application of the empty.

Thus, it is preferred that each mold comprises one or more holes connected to a system that can provide a empty through these holes on the film that is by above the holes, as described in greater detail in This memory. It is preferred that the vacuum system be a vacuum chamber comprising at least two different units, each of them separated into different compartments, as described herein.

The heat can be applied by several media, for example, directly, by passing the film below of a heating element or through hot air, before introduce it on the surface or once on the surface or indirectly, for example, by heating the surface or applying a hot article about the movie, for example, up temperatures of 50 to 120 ° C, or even 60 to 90 ° C, preferably by  example, with infrared light.

The film can be moistened by any medium, for example, directly by spraying a wetting agent (including water, film-shaped material solutions or plasticizers for the film-like material) on the film, before incorporating it on the surface or once on the surface, or indirectly by wetting the surface or by applying a hot article on the movie.

The filling of the first and second bands of Open bags can be made using any known method  for filling items (in motion). The exact method more preferred depends on the shape of the product and the speed of fill.

One method is for example a dosage by flood, whereby the band of open bags goes through a continuous horizontal or basically horizontal movement under a dosage unit, which is static and which has a device for dosing exactly a quantity or volume of product per unit of time. The problem or disadvantage of this method may be that the product is dispensed in areas between open bags, which typically serve as a sealing zone; This can not only be a product waste but also It makes sealing difficult. This problem is especially acute in the case of products in the form of mobile liquids. The products in Paste or gel form are easier to get with this form of filling procedure

In general, preferred methods include the continuous movement in the filling of the line, which uses a dispensing unit placed above the open bags, which has an endless rotating surface with nozzles that typically rotate with one movement continued, where the nozzles move with the same speed than the bags and in the same direction so that each bag open is under the same nozzle or nozzles during the duration of the dispensing stage. After the stage of filled, the nozzles rotate and return to the original position to start another stage of dispensing / filling. Each nozzle, or several nozzles together, are preferably connected to a device that can control exactly that only a quantity or a set volume of product is dispensed during a rotation by mouthpiece, that is, by bag.

It may be preferred that the system filling / dispensing is such that 10 to 100 cycles can be done (filling stages) per minute, or even from 30 to 80 or even from 40 to 70 per minute. This will naturally be adjusted based on the open bag size, surface speed, etc.

A very preferred method for filling the open bags suitable for surface movement following a horizontal rectilinear movement is a method of Filling reciprocal movement. This process preferably use a refillable moving filling station (change the direction of movement) and that is variable speed. The filling station typically has a series of nozzles, in where each one moves with the same speed as the open bags (to be filled) and in the same direction during the period of time in which the product must be dispensed in the open bags Then typically when a bag is full, the nozzle or the nozzles that fill the bag stop their movement along the bag and return in the direction contrary, to stop again, so that it is placed by on top of another open bag (s) that It remains to be filled and then begins again at move in the opposite direction, with the same speed and in the same address as the open bags, until it reaches the speed of the bags and then continue with this speed and start dispensing and filling the bag (s), as in the pre-fill cycle The speed of the return movement may be higher than the speed of movement during fill.

Each nozzle or series of nozzles together is preferably connected to a device that you can control with accuracy that only a set quantity or volume of product is dispense during one rotation per nozzle, that is, in a bag.

The unit or filling station in the process of the invention preferably uses a measuring device flow and / or a positive displacement pump to dose the adequate quantities or volumes of product per open bag, in concrete it has been seen that a positive displacement bag is very exact. In this way, the required amount of product volume is introduced into the pump and this is then introduced into the nozzles For example, if the system is such that you have to fill 60 bags per filling cycle, typically provided 60 nozzles, connected to 60 positive displacement pumps (one pump per nozzle, per bag), which are all connected to A general tank with product.

The pumps can be adjusted depending on the product to be dispensed For example, if the product is a liquid viscous, the pumps have to be more powerful and if it is a Fast filling, surface movement is required.

Other methods that can be used include the flow measurement by using a magnetic flow meter or a mass flow meter, and the pressure flow measurement of filling (which keeps the pressure constant and controls the time of filling and, therefore, the volume).

It may also be preferred to use a system of filling by which, before filling, a second one is placed surface with openings, each of which has a surface area equal to or less than the surface of an open bag, above the band of open bags in continuous motion and which moves continuously in the direction of the bag band and with the speed of the band of open bags, so that each opening remains placed above an open bag during the filling stage and that the space between at least part of the molds are covered, said second being preferably surface an endless moving belt that can rotate.

Filling can be done through the openings on this surface or tape, so that the product You can only enter the open bags and not in the area between bags, which is covered. This is advantageous because the area between the open bags (between the molds), which serves in a way typical as a sealing area when the bags are closed, it remains Product-free, which guarantees a better or more joint easy.

Full open bags close at then which can be carried out by any method. Preferably, this is also done although in the position horizontal and in a constant continuous movement and preferably on the horizontal part of the endless surface described previously.

Preferred in the case of a second band in movement is that the closure is manufactured by feeding continuous of a second material or film, preferably film water soluble on and above the band of open bags and at then preferably the sealing of the first film and of the second film together, typically in the area between the molds and, therefore, between the bags. It preferred supply the closure material over the open bags with the same speed and movement and in the same direction as the bags open.

In the case of the first moving band, prefers the closure material to be the second band of bags closed, full, closing being carried out, as described previously, that is, placing the band of the full bags closed on the open bags continuously, preferably with constant speed and movement in it address of the open bags and which are sealed later with the first movie. Alternatively, the first moving band can also be closed using a film or material as described above for the second band before superimposing and sealing the first and second moving bands of bags. Such embodiments can be prefer in the case of a composition multi-liquid containing products or when require to manufacture bags in a side-by-side relationship, but superimposable

The sealing can be manufactured by any method The sealing can be manufactured in a way discontinuous, for example, transporting the bag band to another sealing area and sealing equipment. However the sealing is preferably done continuously and preferably with constant speed while the band of Closed bags moves continuously and with constant speed, and it can also be done preferably in a horizontal position, preferably also in said horizontal part of the surface.

Preferred methods include heat sealing, solvent welding and sealing with solvent or wet. Thus, it may be preferred to treat only the area that will form the joint with heat or solvent. The heat or solvent can be apply by any method, preferably in the material of closure, preferably only in the areas that will form the meeting.

It is preferred that when heat sealing is used, a roller with cavities the size of the part of the bag that does not It is enclosed by the mold and it has a design of the bags roll (continuously) over the band bags, passing below the roller. Thus, the hot roller only enters contact with the sealing areas, specifically between bags around the edges of the molds. Typically, the sealing temperatures are 50ºC to 300ºC, or even 80ºC at 200 ° C, depending naturally on the material in the form of a film. Also useful is a movable, returnable sealing device, which functions as the movable filling / dosing device, returnable, which brings the area between the molds into contact, around the edges, for a certain time to form the gasket and then away from the sealing area to return back and start another sealing cycle. In the case of heat sealing, it is important that the sealing area of the second band with the first band does not overlap the sealing area of the first and / or second band of the bags.

If it is used sealed with solvent or wet, it may also be preferred to apply heat. Methods of sealed / wet or solvent welded include the selective application of solvents on the area between the molds or on the closure material, for example, by spraying or printing on these areas and then applying pressure over these areas to form the board. For example, they can be used the rollers and tapes for sealing as described previously (optionally also applying heat).

The bands of overlapping and sealed bags are can then cut with a cutting device, which separate the bags from each other, in multi-compartment bags separate overlays and which partially cuts the band of so that multicompartmental bags are formed by a side by side arrangement although superimposable.

The cut can be done by any known method It may also be preferred to make the cut in a manner continued and preferably with constant speed, and preferably in a horizontal position. However, the stage of cutting does not need to be done horizontally, nor continually. For example, the band of closed bags (sealed) can be transported to the cutting device, e.g. eg, to another surface, where the cutting device works. Although, for ease of processing it may be preferred to perform the cutting stage on the same surface as in the stages previous.

The cutting device can be for example a sharp article or a hot article, where in the latter case it "burns" the film / sealing area. May be preferred make it a roller with sharp utensils, such as a knife, with cavities that have the size and design of the bags, which roll over the bags so that sharp utensils only Touch the area you want to cut. Also when the band of bags  moves in one direction (e.g., continuously and / or horizontally, for example, even on an endless surface of the present invention) it may be preferred to use a device static that contacts the area between the bags along of the direction of movement, to cut the bags in the Direction of movement in a continuous way. Then the cut between the bags along the width direction of the Bag band can be made using a cutting stage intermittent, for example, by applying a cutting device for a brief period of time over the area, separating the cutting device and repeating this action with the following group of bags.

The bag, when used in the present invention it can be of any form and material that is suitable for contain the product before use, e.g. eg, without allowing release of bag compositions before putting on Contact the bagged composition with water. The exact realization will depend, for example, on the type and quantity of the compositions in the bag, the required characteristics of the bag for maintain, protect and dispense or release the compositions and the number of compartments in the bag.

In the present invention bags are preferred water soluble having a compartment comprising a liquid composition and another compartment comprising a Powdered or densified powder composition. During manufacturing from the compartment containing liquid typically forms a Air bubble. This air bubble can reduce the compressibility of the bag and, consequently, the ease of dispenser closure after placing the bag inside the same. It has been found that the ease of closure increases when the relationship between the diameter of the air bubble and the dimension Maximum side of the bag profile is approximately 1: 5 a approximately 1: 2. Preferably, the bubble has a diameter from about 9 to about 16 mm. The dimension of the Bubble can be controlled by process parameters.

When used, the water soluble bag will usually placed inside the dishwasher dispenser and released during the main cycle of the washing process of the crockery. However, some dishwasher dispensers do not they are completely water tight, mainly by two Reasons: o The dispenser has some openings that allow the water inlet or the dispenser is sealed with a band of rubber that can deform over time due to the high temperature of the dishwashing process. Water inlet in the dispenser may cause premature leakage of part of the contents of the bag, which is lost at the end of the prewash. This problem is especially acute in the case of bags that they comprise liquid compositions that have a low viscosity since that a considerable amount of the product can be lost before of the main wash cycle. The problem can be solved causing the bag or at least the compartment it contains liquid thereof is from a film-shaped material that is  designed to survive the prewash cycle and release the contents of the bag on or after the start of the wash cycle principal. In European dishwashers, prewashing is done usually in a cold water cycle (approximately at 20 ° C or less) without detergent and with a duration of approximately 10 to 15 min.

Preferably the film-shaped material it has a water solubility, according to the defined test more hereinafter, of less than about 50%, more preferably less than about 20% and especially of less than about 5%, in cold water conditions (20ºC or lower) when exposed to water for at least 10 minutes, preferably for at least 15 minutes; and a solubility in water of at least about 50%, more preferably of at less about 75% and especially at least approximately 95%, in hot water conditions (30 ° C or higher, preferably 40 ° C or higher) when exposed to water for about 5 minutes and preferably when exposed  to water for about 3 minutes. These materials in film form are referred to herein as practically insoluble in cold water and soluble in hot water. TO Sometimes, this is simply abbreviated as "water soluble hot".

50 grams ± 0.1 gram of material are added bag-shaped to a heavy 400 ml beaker before and after 245 ml ± 1 ml of distilled water. Mix it is maintained at the desired temperature using a water bath and shaking vigorously on a magnetic stirrer set at 600 rpm for the desired time. Then the mixture is filtered to through a qualitative sintered glass filter folded with a maximum pore size of 20 µm. Water is removed from filtrate collected by any conventional method and is determine the weight of the remaining material (which is the fraction dissolved or dispersed). The% solubility is then calculated or dispersibility.

Water insoluble commercial films Cold and hot water soluble include BP26, marketed by Aicello, L10 and L15, marketed by Aquafilm, VF-M and VM-S, marketed by Kuraray, and E-2060, marketed by Monosol.

In a preferred embodiment a bag multicompartmental comprises a first compartment comprising a liquid composition and a second compartment comprising a powder composition or densified powder. Preferably, the Liquid-containing compartment is made of a material soluble in hot water as described previously in the present memory and the compartment containing powder or powder densified is made of a cold water soluble material, it is that is, a material that is soluble to a degree of at least 50%, preferably at least 75%, more preferably at least 95%, in weight under cold water conditions (20ºC or less) when exposed to water for about 5 minutes and preferably when expose to water for about 3 minutes. Due to the way in which European dishwashers work (these are filled with cold water and cold water is heated by a heater), the compartment made of hot water soluble material needs more time to dissolve than the compartment made of a cold water soluble material. This type of bag allows a delayed release of the liquid composition thus optimizing the use of the detergent composition. Preferably, the composition liquid comprises detergent enzyme, this being advantageous from the view of stability during storage of the enzyme being the enzyme separated from the bleach and the highly alkaline materials contained in the composition in densified powder or powder. In addition, the compartment it contains liquid (practically insoluble in cold water and soluble in water hot) will need more time to dissolve or disintegrate than the compartment containing the solid (soluble in cold water), minimizing the negative interaction in the wash solution between the bleach and the enzymes and between the surfactant and the enzymes and providing better removal of protein stains as well as benefits of stain removal in later stages of the dishwashing process.

The compartments of the bags containing solid compositions, in particular compositions comprising oxygen releasing bleach, they are usually perforated with in order to allow the escape of the oxygen formed. However, the drilling holes can also allow escape of perfumes or the exit of bad smells. For example, the surfactants frequently have an associated unpleasant smell and When these bags are packed in a secondary container, the unpleasant smell of the surfactant can be concentrated in the top container space and escape every time the user opens the container This problem can be avoided by including the surfactant. in the liquid composition, since the compartments that Contain the liquid must be free of drilled holes. Thus, according to another embodiment, the liquid composition comprises a surfactant Another advantage of having the surfactant in the phase liquid is that the problems of loading the surfactant are avoided on the solid material. Another advantage is that the surfactant is releases with a certain delay regarding the composition solid, which allows better bleaching performance and enzymes, which can be adversely affected by interaction between surfactant and tableware surfaces, Cutlery and glassware.

Preferably the perfume is introduced into the solid composition and perforation allows the release of perfume before using the product in the dishwasher.

The films practically insoluble in water cold and hot water soluble have a moisture content and of relatively low plasticizer, so the film it would require an important time and temperature to perform the heat seal. These requirements may cause damage to the film. such as pores when the film is stretched over the mold, which can lead to leakage, especially appearance problematic in the case of bags containing liquid. By consequently, it is preferred that compartments made of basically cold water insoluble and water soluble films hot and housing liquids are sealed using solvent, which partially hydrates the film before sealing, reducing the time and temperature required for sealing, generating solid joints and avoiding the formation of pores. In the preferred embodiment of bags with a differential solubility that they have a compartment that comprises a liquid composition and another compartment comprising a powder composition, wherein the compartment that contains liquid is made of material basically insoluble in cold water and soluble in hot water and the dust-containing compartment is made of material that is soluble in cold water, it is preferred that the compartment containing liquid is sealed by solvent sealing while the compartment containing liquid is sealed to the compartment that Contains powder by heat sealing.

Although the nature of bagged products It is such that they dissolve or disperse easily in water, it can be prefer that disintegrating agents such as effervescent sources, water swellable polymers or clays are present in the bag itself and / or the product contained therein, in particular effervescent sources based on an acid and a carbonate source Suitable acids include acids organic carboxylic acids such as fumaric acid, maleic acid, malic acid and citric acid; adequate carbonate sources include sodium salts of carbonate, bicarbonate and percarbonate. The preferred levels for disintegration aids or Effervescence sources, or for both, are from 0.05% to 15%, even 0.2% to 10% or even 0.3 to 5%, by weight of the composition Total bagging.
