Description

A SANITARY AGENT
Field of the Invention
The invention relates to a sanitary agent for cleaning, disinfecting and/or perfuming a sanitary appliance.
In particular, the present invention relates to a sanitary agent which can adhere to an internal wall of a water-closet bowl or a urinal, remaining attached for a high number of water flushes up to its final consumption.
Background Art
Sanitary appliances, for example hygienic toilet bowls or urinals fixed to a wall, have to be subjected to repeated cleaning and disinfecting operations in order to be able to maintain adequate hygienic sanitary conditions.
The prior art comprises hanging sanitary agents by means of hooking device positioned in the water closet container, where one exists; the emission of the sanitary agent occurs at each discharge flush operation into the bowl. Also known are sanitary agents which are fixed to the perimeter edge of the toilet bowl by means of a support; these sanitary agents are normally inserted in particular devices, like cages, provided with the support means, such as for example a plastic bracket, and which also include slits and/or holes such as to enable a portion of the sanitary agent to exit at each flush of the water.
The above-described sanitary agents, when struck by the water which irrigates the toilet bowl, enriches the water with the substances contained in the agents, thus providing the elements required for deterging, descaling, deodorising and/or disinfecting the bowl.
However, the above described hygienic devices present some drawbacks, such as for example not guaranteeing an adequate anchoring to the perimeter edge of the bowl due to the fragility of the support means, with the consequence that there might be a possible accidental fall of the sanitary agent contained in the sanitary agent into the toilet bowl.
Further, these devices are not very practical and hygienic; during manual cleaning of the edge of the toilet bowl or during the cleaning of the inside of the bowl by use of the toilet brush, the support means fixed to the edge of the bowl can be accidentally shifted and it is therefore necessary to reposition it. Further, on substitution of the sanitary agent, due to its consumption, it is necessary to act manually with ensuing operative and hygienic difficulties for 5 the user, as the devices are often positioned in poorly-accessible places, in any case not ideal from the hygienic point of view.
Further, it is difficult to apply these devices to urinals, as urinals are generally lacking in edges or parts in relief on which the support means can be fixed. In the case of urinals or urinal bowls, pastilles are often use, positioned in the 10 lower part thereof, at the position of the drain. However, these pastilles are generally partly washed away by the water flush and also cause undesired backsplash.
In recent times alternative solutions have been looked for, by eliminating the presence of the devices having a support means to be fixed to the perimeter i s edge of the bowl.
The prior art comprises certain solutions to the above-cited problem, in which sanitary agents, in particular solid or semi-solid soaps can adhere stably to the internal wall of a WC bowl or a urinal in order to be subjected to regular water flushes.
0 For example, the international application published at no. WO2008/100393 in the name of Johnson and Sons proposes a solid soap able to adhere to the surface of the bowl and guarantee at the same time adequate cleaning thereof; however, this soap has to contain a very high amount of solid surfactant substance, between 75% and 99% in weight of the weight of the 5 soap.
Such a high percentage required for enabling sufficient adhesion leads to a high cost, as well as to a greater environmental impact, especially when substances deriving from benzene are used.
Further, European patent EP 1 086 199 in the name of Buck-Chemie GmbH 0 describes a sanitary agent which can be applied directly on the surface of the sanitary appliance, the sanitary agent having a viscosity of at least 15,000 mPas and comprising an adhesion promoter such as poly oxy alcohol alkane, cellulose, etc. However this excessive viscosity can fail to guarantee adequate removal of the limescale deposits and a homogeneous distribution of the detergent contained in the sanitary agent.
Further, during use, the sanitary agent deforms, causing the components constituting it to drip downwards in an undesirable way. A further disadvantage is given by the fact that in order to be applied adequately to the part of the sanitary appliance, the sanitary agent described in the patent application obligatorily requires the use of a batching system normally constituted by rigid plastic material, with the consequence of an undesired and significant use of plastic material.
Thus an alternative must be sought which enables good adhesion while at the same time guaranteeing sanitary-hygienic treatments of the sanitary appliance which are satisfactory.
EP application 2 141 221 in the name of Manitoba described a detergent pastille having a substantially flat adhesive surface for anchoring to a wall of the WC bowl and a shell-shaped surface such as to be subjected to the action of the flush water.
A problem of the products using an adhesive part is that the adhesive part does not completely dissolve following the action of the flush water and therefore, once the detergent part of the pastille has been consumed, a manual intervention is required to remove the residue of the detergent pastille that has remained adhering to the part of the WC bowl.
Even today the technical problem persists of having available a sanitary agent which: a) exerts a satisfactory and lasting cleaning action and/or perfuming and/or disinfection of a sanitary appliance, b) has no need of considerable manual operations for removal of eventual adhesive residual portions of the sanitary agent at the end of its use, and c) has a portion which adheres appropriately to the internal surface of a sanitary appliance during use thereof.
Therefore the aim of the present invention is to provide a sanitary agent for treatment of a sanitary appliance which constitutes an alternative to the solutions provided by the prior-art documents as cited above. In particular, the aim of the present invention is to provide a sanitary agent for treatment of a sanitary appliance, the sanitary agent comprising at least an adhesive component and at least a component that is useful for the treatment, the adhesive component being capable of enabling the sanitary agent to remain in adherence for a large number of water flushes to a sanitary appliance of any shape and, at the same time, once the component of the sanitary agent used for the treatment is consumed, to be easily dissolved in the water of further flushes.
Disclosure of Invention
In a first aspect, the present invention relates to a sanitary agent to be used for deterging, disinfecting and/or perfuming a sanitary appliance.
The present Applicant has found that a sanitary agent for treating a sanitary appliance, comprising an active body, solid or semi-solid, including a treatment compound having at least an active element for treatment of the sanitary appliance and at least a surfactant, characterised in that it comprises an adhesive layer positioned on a portion of the external surface of the active body, in which the adhesive layer comprises at least an adhesive element deriving from colophony resin, destined to realise adhesion of the active body to the wall of the sanitary appliance, is capable of enabling the adhesion to last for a high number of water flushes, the sanitary agent dissolving substantially completely at the end of the operating cycle thereof and being of a shape such as to be able to adhere to sanitary appliances of any shape. Further, the present invention has the advantage of providing a sanitary agent which comprises an adhesive layer and a treatment compound, in which the treatment compound can be any of the traditionally known treatment compositions.
In this context and in the following claims, the term "sanitary appliance" is understood to mean a water-closet toilet bowl, a urinal bowl, a urinal or any other like apparatus which is usually subjected to water flushes in order to maintain cleanliness and hygiene thereof.
In this context, and in the following claims, the term "treatment of a sanitary appliance" is understood to mean cleaning, hygienising, disinfecting, perfuming and removing limescale, and other like operations applicable to the sanitary appliance.
In this context and in the following claims, the term "active element for the treatment" is understood to means an element dedicated to cleaning, deterging, foaming, perfuming, deodorising, disinfecting, water-colouring, polishing, or any other element which is soluble in water and useful for the treatment to which the sanitary appliance is to be subjected.
In this context and in the following claims, the term "semi-solid body" is intended to mean a body having a pasty consistency, or having a consistency which is such as to be slightly modifiable in shape by manual pressure, but such as to maintain over time the given shape, even following the action of weak external forces, such as a water flush or discharge.
In this way, whatever the form of the wall of the sanitary appliance to which the sanitary agent is to be made to adhere, the shape of the sanitary agent can be appropriately modelled on the basis of the shape of the wall in order to guarantee good adhesion. This shape can be maintained over time, except for the reduction in mass due to its dissolving by action of the flush water. The sanitary agent of the present invention can be consumed progressively and appropriately at each flush of water of the sanitary appliance, activating an emulsifying and/or solubilising process. Following each water discharge, first the treatment compound comprising the active ingredient for treatment of the sanitary appliance is progressively dissolved into the water. Thereafter, when the almost-totality of the composition has been consumed, after a series of water discharges, the adhesive element of the sanitary agent begins to be exposed to the action of the water which, in combination with the residual part of the treatment compound, enables complete removal of the adhesive element.
In this way, when the treatment compound has been consumed, only a small portion of the adhesive element remains in contact with the wall of the treated sanitary appliance, becoming easily removable by means of appropriate cleaning tools for the sanitary appliance, such as brushes and the like. The adhesive element is preferably a terpene deriving from colophony (colophony resin); more preferably, the terpene is a linear colophony ester, such as for example Bremasin 1205.
Colphony is a solid yellow vegetable resin (abietic anhydride), which is transparent and a residue of the distillation of trementine (conifer resins Pinus palustris and other pines of the pinaceae family.
The quantity of the adhesive element derived from colophony resin is comprised in the range 0.2-20%, more preferably in the range of 0.2-10%, still more preferably 1 -3% in weight with respect to the total weight of the sanitary agent.
The adhesive element preferably derived from colophony resin is applied on the external surface of the active body by application via spreading, spraying, or any other known method which enables a homogeneous distribution of the adhesive element on the external surface of the active body.
The adhesive layer positioned on a portion of the external surface of the active body of the sanitary agent preferably comprises, beyond the adhesive element derived from colophony resin, a fatty substance and/or at least a silicone substance, such as for example partially-hydrogenated mineral oils or fats, silicone fats or derivatives thereof, Vaseline, petroleum jelly, silicone polymers, hydrocarbon synthetic copolymers with a kinematic viscosity comprised between 3,000 and 9,000 cStokes (at 100°C).
As mentioned herein above, the sanitary agent comprises a treatment compound having at least an active element for the treatment and at least a surfactant.
The active element is preferably a detergent element, a perfume or a disinfectant.
The quantity of the at least an active element is preferably comprised in the interval from 1 -75% in weight with respect to the total weight of the sanitary agent.
The at least a surfactant is preferably selected from a group consisting of non-ionic surfactants, anionic surfactants, cationic surfactants, amphoteric surfactants, and combinations thereof. The non-ionic surfactants are preferably selected from the group consisting of long-chain alcohols (from about 10 to about 20 carbon atoms), such as polyoxyethylene derivatives of fatty acids, starch alkanols of fatty acids, alkyi polyglucosides (APG), natural and/or synthetic etoxylated alchohols, amine oxides.
The anionic surfactants are preferably selected from the group consisting of compounds having carbon atom chains ending with a caroxylate or sulphanate group, such as for example soaps, alkyi ether sulphates (LES/AES), alkyi sulphates (LS/AS), a-olefin sulphonates (AOS), alkyi ether carboxylates, sulphosuccinates, aromatic sulphonates.
The cationic surfactants are preferably selected from the group consisting of long carbon atom chains (from about 10 to about 20 carbon atoms) terminating with a quaternary amine group, such as for example alkyi hydroxyethyl dimethyl ammonium chloride, banzalconium chloride, cetyl- trimethyl ammonium bromide or chloride, hexadecyl-trimethyl ammonium bromide or chloride, and the like.
The surfactant amphoterics are preferably selected from a group consisting of amino carboxyl acids, alkyi betaine, such as for example 12 betaine, starch alkyls, propyl betaine, and amphoacetates.
More preferably, the at least a surfactant is a mixture of at least a non-ionic surfactant and/or at least an anionic surfactant.
The quantity of the at least a surfactant is comprised in the range from 25- 75%, more preferably in the range from 30-70% in weight with respect to the total weight of the sanitary agent.

15 Best Mode for Carrying Out the Invention
Example 1
Sanitary agent 1 (invention).
The first treatment compound for a sanitary appliance was prepared. The compound comprised the non-ionic surfactant marketed under the name of 0 mergital CS25 (cethearet25) by Cognis, the non-ionic surfactant marketed under the name of comperlanl OO by Cognis, the non-ionic surfactant marketed under the name glucopon by Cognis, the anionic surfactant alkyl sulphate marketed under the name Texapon V95 by Cognis, sodium sulphate and a perfume in percentages as follows:
5 Non-ionic surfactant mergital CS25 (cethearet25) 39%
Non-ionic surfactant comperlanl OO 8%
Non-ionic surfactant glucopon 50g 5%
Anionic surfactant alkyl sulphate Texapon V95 2%
Sodium sulphate 38%
Perfume 5%
Foamer DERIPHAT 160 C (Cognis) 3% The compound was prepared by mixing the various components in a laboratory vertical-arm mixer at ambient temperature, leaving it to mix for about 30 minutes up to obtaining a homogeneous, plastic and modellable paste.
The sanitary agent 1 presented as a semi-solid active body, with a substantially flattened-cylinder shape, with a diameter of the base surfaces of about 4cm, and a height (thickness) of about 0.4 cm, including the treatment compound 1 and comprising an adhesive layer positioned on a portion of the external surface of the active body. The following were spread on the adhesive layer: 0.5 grams of linear colophony ester of a type known as BREMASIN 1205, available from the company Kraemer. Thus a sanitary agent 1 was obtained having a total weight of 12 grams, which was made to adhere to the hard surface of the internal wall of a toilet bowl, following a flushing of the toilet and pressing the adhesive layer against the wall of the sanitary appliance to be treated for about ten seconds, to guarantee good adhesion.
The sanitary agent 1 was subjected to a series of 100 homogeneous water flushes, which caused progressive release up to complete consumption of the treatment compound, leaving a residue of colophony resin of less than 10% of the initial quantity of the colophony present in the sanitary agent; this resin residue was easily eliminated by using a toilet brush.
In this way, using the sanitary agent 1 of the present invention, a good adhesion of the sanitary agent to the sanitary appliance to be treated was obtained, as well as an efficient hygienisation of the sanitary appliance and at the same time it was not necessary to touch non-hygienic zones of the sanitary appliance (the toilet bowl) with the hands in order to remove the residues of the sanitary agent 1 at the end of its use phase. Finally, it was not necessary to use an applicator object in order to position the sanitary agent correctly without entering into contact with the walls of the toilet bowl.
