Description

"Single dose plastic container with detergent for direct removal of dirt"

The invention relates to a single-dose plastic container containing a liquid, foam-like or gel-like cleaning agent for the direct removal of dirt.

Wet cleaning wipes are known from the prior art which can be used for direct stain removal from textiles. These cleaning wipes have the disadvantage, among other things, that the amount of liquid is too small to be able to remove stubborn dirt. Furthermore, direct skin contact with the damp cleaning cloth is essential during the entire cleaning process, i.e. When the cleaning cloth is unpacked, i.e. before the actual cleaning begins, the user is contacted with the cleaning agent. In addition, in order to avoid drying out, such cleaning wipes have to be packaged in a complex manner.

Furthermore, various travel detergent concentrates are known in the prior art. These travel detergent concentrates cannot be used directly for stain removal, but must first be diluted with water at the place of use.

Furthermore, cleaning agents, including sprays, which are suitable for removing numerous stains from textile supports are known. Such agents are not pre-portioned as a single dose unit, so that exact dosing is difficult. In addition, because of the filling quantity of often more than 50 ml, such agents cannot easily be carried along in a space-saving manner, so that the agent is not immediately and immediately available to the user if required. Another disadvantage is that after such stain removal agents have been opened once, by penetrating air, oxygen-sensitive cleaning substances can be oxidized during storage. In addition, fragrances can be released over a prolonged period of time, which can lead to a change in the smell of the agent and, when used, has an immediate effect on the textile to be cleaned.

WO-A-02/079362 discloses a method and a device for stain cleaning a fabric by means of a liquid cleaning agent, suitable for multiple use Use, wherein the device comprises more than one absorbent for absorbing at least a portion of the detergent used from the tissue and a storage means for absorbing more than one absorbent.

WO-A-02/079363 discloses a device for stain cleaning a fabric using a liquid detergent composition, the device comprises a reservoir for receiving the composition, an applicator suitable for applying the composition to the fabric and an absorbent for absorbing at least one Part of the composition of the fabric.

WO 01/79413 discloses a method for removing a water stain from a fabric article, in which the fabric surface to be cleaned is placed on a hard surface, the soiled area is moistened with clean water, a clean cloth is placed on the soiled area and over the clean area Cloth irons. Alternatively, a method for removing a water stain from a fabric article is described that involves wetting the soiled area with water and then drying it with a hair dryer or in a tumble dryer. The method described there does not relate to the use of a liquid, foam-like or gel-like cleaning agent for the direct removal of dirt.

EP 1 069 177 discloses a tissue treatment applicator with a tip containing a bleach and surfactant. This tissue treatment applicator is used for mechanical and chemical stain removal. A single-dose plastic container for a liquid, foam-like or gel-like cleaning agent for the direct removal of dirt, however, is not described.

The use of single-dose plastic containers for a liquid, foam-like or gel-like cleaning agent for the direct removal of dirt is not known from the prior art.

The present invention relates to a single-dose plastic container containing a liquid, foam-like or gel-like cleaning agent for the direct removal of dirt at room temperature from hard or soft surfaces, characterized in that the single-dose plastic container has a filling volume of up to 5.0 ml detergent.

The single-dose plastic containers that can be used according to the invention serve to hold liquid, foam-like or gel-like cleaning agents for the direct removal of soiling, whereby for cleaning purposes the entire detergent content of the single-dose plastic container can be applied to the place of soiling to be cleaned, apart from practically no or only minimal residual fill quantities.

In the context of the present invention, a single-dose plastic container is understood to mean a product which is suitable for absorbing an amount of cleaning agent which is sufficient for a single application.

In the context of the present invention, a liquid, foam-like or gel-like cleaning agent for the direct removal of dirt is understood to mean a product for single use, in which the entire cleaning agent, after opening the single-dose plastic container, without further dilution, is applied directly to the hard or soft surface to be cleaned for the purpose of development the cleaning effect is applied.

Preferred are liquid, foam-like or gel-like cleaning agents, in which the formation of difficult-to-remove wreaths and edges around the original stains does not occur and practically no increased re-soiling occurs at the originally stained area.

The cleaning agent for the direct removal of dirt, hereinafter also referred to as stain removal agent, which can be removed as a liquid, gel or foam from a single-dose plastic container that can be used according to the invention, is applied to the stain and, if necessary, with a cloth, a brush or a Sponge, which may be damp, rubbed into the stain. The degree to which the mechanical treatment of the stain must be selected in connection with the use of the cleaning agent also largely depends on the type and age of the stain and on the effectiveness of the agent. In mild cases, mechanical treatment can be dispensed with entirely. The residues of the cleaning agent are then removed mechanically. An extraction and / or adsorbent can in particular be used to remove or suction the liquid, foam-like or gel-like cleaning agent. Suitable absorbents and / or adsorbents are preferably based on woven or non-woven materials, selected from the group comprising paper towels, textile towels or microfiber towels. The removal and / or adsorbent agent is particularly preferred, suitable for absorbing cleaning agents from the soft or hard surface to be cleaned, selected from the group comprising a cloth or a sponge. The absorption and / or adsorbent is usually dry.

Depending on the type of cleaning agent used, its residues can be removed from the soft or hard surfaces to be cleaned, such as textiles, for example by evaporation, brushing or vacuuming.

The reason for the excellent effectiveness of the agent which can be used according to the invention is, inter alia, suspects that the liquids and active ingredients contained in the cleaning agent convert the stain components into a mobile form and the stain components are then, in this form, distributed in the object to be cleaned, such as textile, 'oxidized, and / or by an absorption / adsorbent recorded and removed with this.

In its simplest configuration, the single-dose plastic container is formed in one piece, preferably from a polymeric material.

Single-dose plastic containers suitable according to the invention are preferably made of polyethylene, particularly preferably low-density polyethylene (LDPE). In addition, single-dose plastic containers that can be used according to the invention can also be formed from polypropylene or polypropylene-containing polymeric material. Furthermore, it is provided according to the invention that single-dose plastic containers suitable according to the invention are preferably formed from a polymeric material which is free from plasticizers. According to the invention, however, the polymeric material can optionally also contain plasticizers and optionally pigments and / or other additives.

However, angular moldings are also suitable. In principle, different geometrical configurations of the hollow body, such as for example Santa Clauses, Easter bunnies or other figures, can be shaped. Preferred single-dose plastic containers are without integral compartmentalization devices, but can also have such for the establishment of internal, separate chambers.

Single dose plastic containers can have a flag, for example. A flag is an elongated surface element arranged on the single-dose plastic container, in particular on the outer container base, which is suitable for applying information. However, single-dose plastic containers that do not have a flag are preferred.

It is particularly advantageous that the single-dose plastic containers can be embossed and / or decorated in the mold during manufacture, in particular blow molding. By designing the tool shape accordingly, a motif can be transferred to the single-dose plastic container in mirror image. In this way, the surface of the single-dose plastic container can be designed practically as desired. For example, information such as calibration marks, application notes, hazard symbols, brands, weight, filling quantity, expiry date, pictures, etc. can be applied to it. However, such information can also, if necessary additionally, be applied in the form of an applied, preferably adhesive, pre-printed label.

The wall of the single-dose plastic containers can be in the middle, i.e. have at least one, preferably at least two, opposing waists between the bottle neck and the bottom of the single-dose plastic container. Such waists of the wall of the single-dose plastic container can make emptying the direct, liquid cleaning agent considerably easier.

In a preferred embodiment, the single-dose plastic containers can have grooves and / or grooves and / or roughening on their outer sides which prevent fingers from slipping off the container during the stain treatment and / or Increase grip. In particular, such grooves and / or grooves and / or roughening can be formed in the region of the waist (s). .

The Bottlepack® machines from Rommelag or Cooker plastic. It is an industrial process for the rational packaging of, among other things, individually dosed cleaning agents for the direct removal of dirt, in which single-dose plastic containers are produced, filled and sealed immediately in an automatic machine. The containers are usually made of plastic granulate by extrusion blowing, vented via a blowing and filling mandrel with an exhaust air line and at the same time filled with the desired amount of liquid or gel using a piston metering machine and three-way valve connected to the mandrel. After removing the dome, the container is welded with separate head tools. In this way, hermetically sealed single-dose plastic containers filled with cleaning agent in the desired shape are obtained to a desired degree of filling. The molding tools or the method can be designed in such a way that blocks are obtained from interconnected single-dose plastic containers.

Single-dose plastic containers suitable according to the invention are preferably made of polyethylene, particularly preferably low density polyethylene (LDPE).

Some cleaning agent components suitable according to the invention are explained in more detail below.

surfactants

Anionic, cationic, ampho- and / or nonionic surfactants can be used as surfactants for the production of the cleaning agents. For example, anionic surfactants of the sulfonate and sulfate type can be used. Suitable surfactants of the sulfonate type are preferably C _9-13 -Alkylben- sulfonates, olefin sulfonates, ie mixtures of alkene and hydroxyalkane sulfonates, and the disulfonates obtained, for example, from C ₁₂ ι ₈ monoolefins with terminal or internal double bond by sulfonation with gaseous sulfur trioxide and subsequent alkaline or acidic hydrolysis of the sulfonation products, (n. Also suitable are alkanesulfonates obtained from C _12-18 alkanes, for example by sulfochlorination or sulfoxidation with subsequent hydrolysis or neutralization the esters of α-sulfofatty acids (ester sulfonates), for example the α-sulfonated methyl esters of hydrogenated coconut, palm kernel or tallow fatty acids, are also suitable.Sulfonation products of unsaturated fatty acids, for example oleic acid, are also suitable in small amounts, preferably in amounts not above about 2 to 3% by weight, in particular α-sulfofatty acid alkyls ter preferred, which have an alkyl chain with no more than 4 carbon atoms in the ester group, for example methyl ester, ethyl ester, propyl ester and butyl ester. The methyl esters of α-sulfofatty acids (MES), but also their saponified disalts, are used with particular advantage.

Other suitable anionic surfactants are sulfonated fatty acid glycerol esters. Fatty acid glycerol esters are to be understood as the mono-, di- and triesters and their mixtures as obtained in the production by esterification of a monoglycerol with 1 to 3 moles of fatty acid or in the transesterification of triglycerides with 0.3 to 2 moles of glycerol become. Preferred sulfated fatty acid glycerol esters are the sulfonation products of saturated fatty acids having 6 to 22 carbon atoms, for example caproic acid, caprylic acid, capric acid, myristic acid, lauric acid, palmitic acid, stearic acid or behenic acid.

The alk (en) yl sulfates are the alkali and in particular the sodium salts of the sulfuric acid half esters of C ₁₂ -C ₁₈ fatty alcohols, for example from coconut fatty alcohol, tallow fatty alcohol, lauryl, myristyl, cetyl or stearyl alcohol or the C ₁₀ -C ₂₀ oxo alcohols and those half-esters of secondary alcohols of this chain length are preferred. Also preferred are alk (en) yl sulfates of the chain length mentioned, which contain a synthetic, straight-chain alkyl radical produced on a petrochemical basis and which have a degradation behavior analogous to that of the adequate compounds based on oleochemical raw materials. Fatty acid derivatives of amino acids, for example of N-methyl acid (tauride) and / or of N-methyl glycine (sarcoside) are suitable as further anionic surfactants. The sarcosides or sarcosinates, and in particular sarcosinates of higher and optionally mono- or polyunsaturated fatty acids such as oleyl sarcosinate, are particularly preferred.

Soaps are particularly suitable as further anionic surfactants. Saturated fatty acid soaps are suitable, such as the salts of lauric acid, myristic acid, palmitic acid, stearic acid, hydrogenated erucic acid and behenic acid, and in particular from natural fatty acids, e.g. Coconut, palm kernel or tallow fatty acids, derived soap mixtures. The anionic surfactants, including the soaps, can be in the form of their sodium, potassium or ammonium salts and also as soluble salts of organic bases, such as mono-, di- or tri-ethanolamine. The anionic surfactants are preferably in the form of their sodium or potassium salts, in particular in the form of the sodium salts.

The anionic surfactants are present in the cleaning agents which can be used according to the invention preferably in amounts of 0.05 to 30% by weight and in particular in amounts of 0.1 to 10% by weight and preferably 1 to 5% by weight.

It is also possible to use alkoxylated, preferably ethoxylated or ethoxylated and propoxylated, fatty acid alkyl esters, preferably having 1 to 4 carbon atoms in the alkyl chain, in particular fatty acid methyl esters, as described, for example, in Japanese Patent Application JP 58/217598. Preferred nonionic surfactants are C ₁₂ -C ₁₈ fatty acid methyl esters with an average of 3 to 15 EO, in particular with an average of 5 to 12 EO. C ₁₂ -C ₁₈ fatty acid methyl esters with 10 to 12 EO in particular can be used as surfactants.

Another class of nonionic surfactants that can be used advantageously for the production of cleaning agents are the alkyl polyglycosides (APG). Alkypolyglycosides that can be used satisfy the general formula RO (G) _z , in which R denotes a linear or branched, in particular methyl-branched, saturated or unsaturated, aliphatic radical having 8 to 22, preferably 12 to 18, carbon atoms and G is the Symbol is that for a glycose unit with 5 or 6 carbon atoms, preferably for Glucose. The degree of glycosidation z is between 1.0 and 4.0, preferably between 1.0 and 2.0 and in particular between 1.1 and 1.4.

Nonionic surfactants of the amine oxide type, for example N-cocoalkyl-N, N-di- m ^{'ethylaminoxid} and N-tallowalkyl-N, N-dihydroxyethylamine oxide, and the fatty acid alkanolamides may be suitable for production of the detergents.

So-called gemini surfactants are suitable as further surfactants for the preparation of the cleaning agents which can be used according to the invention. These are generally understood to mean compounds which have two hydrophilic groups and two hydrophobic groups per molecule. These groups are generally separated from one another by a so-called “spacer”. This spacer is generally a carbon chain which should be long enough that the hydrophilic groups are sufficiently far apart that they can act independently of one another. Such surfactants are distinguished generally by an unusually low critical micelle concentration and the ability to greatly reduce the surface tension of the water, but in exceptional cases the term gemini surfactants is understood to mean not only dimers but also trimer surfactants.

Gemini surfactants for the production of cleaning agents are, for example, sulfated hydroxy mixed ethers according to German patent application DE-A-43 21 022 or dimer alcohol bis and trimeral alcohol tris sulfates and ether sulfates according to German patent application DE-A-195 03 061. End group-blocked dimeric and trimeric mixed ethers according to German patent application DE-A-195 13 391 are distinguished in particular by their bi- and multifunctionality. The end group-closed surfactants mentioned have good wetting properties and are low-foaming.

Cationic surfactants

The cleaning agents which can be used according to the invention can optionally also contain cationic surfactants. Suitable cationic surfactants are, for example, surface-active quaternary compounds, in particular with an ammonium .sulfonium, phosphonium, iodonium or arsonium group, as described, for example, by KH Wallhäußer in "Practice of Sterilization, Disinfection - Preservation: Germ Identification - Industrial Hygiene" (5th ed - Stuttgart; New York: Thieme, 1995) as antimicrobial agents writes. Through the use of quaternary. The agent can be designed with an antimicrobial effect on surface-active compounds with an antimicrobial effect or its antimicrobial effect which may already be present due to other ingredients can be improved.

Particularly preferred cationic surfactants are the quaternary, partly antimicrobial ammonium compounds (QAV; INCI Quaternary Ammonium Compounds) 'according to the general formula (R ^I ) (R ") (R ^I ") (R ^IV ) N * X-, in which R ¹ to R ^ιv identical or different C _-22- alkyl radicals, C _-28- aralkyl radicals or heterocyclic radicals, two or, in the case of an aromatic integration, as in pyridine, even three radicals together with the nitrogen atom, the heterocycle, for example a pyridinium or imidazolinium compound formation, form, represent and X ^{~ are} halide ions, sulfate ions, hydroxide ions or similar anions. For an optimal antimicrobial effect, at least one of the residues preferably has a chain length of 8 to 18, in particular 12 to 16, carbon atoms. QAV can be prepared by reacting tertiary amines with alkylating agents such as methyl chloride, benzyl chloride, dimethyl sulfate, dodecyl bromide, but also ethylene oxide. The alkylation of tertiary amines with a long alkyl radical and two methyl groups is particularly easy, and the quaternization of tertiary amines with two long radicals and one methyl group can also be carried out using methyl chloride under mild conditions. Amines which have three long alkyl radicals or hydroxy-substituted alkyl radicals are not very reactive and are preferably quaternized with dimethyl sulfate.

Suitable QACs are, for example, benzalkonium chloride (N-alkyl-N, N-dimethyl-benzyl ammonium chloride, CAS No. 8001-54-5), benzalkon B (m, p-dichlorobenzyl-dimethyl-C ₁₂ -alkylammonium chloride, CAS No . 58390-78-6), benzoxonium chloride (benzyl-dodecyl-bis (2-hydroxyethyl) ammonium chloride), cetrimonium bromide (N-hexadecyl-N, N-trimethyl-ammonium bromide, CAS No. 57-09-0) , Benzetonium chloride (N, N-dimethyl-N- [2- [2- [p- (1, 1, 3,3-tetramethylbutyl) phenoxy] ethoxy] ethyl] benzylammonium chloride, CAS No. 121-54-0), Dialkyldimethylammonium chlorides such as di-n-decyldimethylammonium chloride (CAS No. 7173-51-5-5), didecyldimethylammonium bromide (CAS No. 2390-68-3), dioctyldimethylammonium chloric, 1-cetylpyridinium chloride (CAS No. 123 -03-5) and thiazoline iodide (CAS No. 15764-48-1) and their mixtures. Preferred QACs are the benzalkonium chlorides with C ₈ -C ₁₈ -alkyl radicals, in particular C ₁₂ -C ₁ -alkyl-benzyl-dimethylammoni- monium chloride. A particularly preferred QAV cocospentaethoxymethylammonium methosulfate (INCI PEG-5 Qocomonium methosulfate; Rewoquat ^® CPEM).

In order to avoid possible incompatibilities of the antimicrobial cationic surfactants with the anionic surfactants contained according to the invention, anionic surfactants that are as compatible as possible and / or as little as possible cationic surfactant are used or, in a particular embodiment of the invention, no cationic surfactants with an antimicrobial effect are used. Parabens, benzoic acid and / or benzoate, lactic acid and / or lactates can be used as antimicrobial substances. Benzoic acid and / or lactic acid are particularly preferred.

The cleaning agents which can be used according to the invention can contain one or more cationic surfactants in amounts, based on the total composition, of from 0 to 5% by weight, greater than 0 to 5% by weight, preferably 0.01 to 3% by weight, in particular 0 Contain 1 to 1 wt .-%.

Amphoteric surfactants

Suitable amphoteric surfactants are, for example, betaines of the formula '(R ¹ ) (R ² ) (R ³ ) N ⁺ CH ₂ CO ^~ , in which R ^{1 is} an alkyl radical with 8 to 25, preferably 10 to, optionally interrupted by heteroatoms or heteroatom groups 21 carbon atoms and R ² and R ^{3 are} identical or different alkyl radicals having 1 to 3 carbon atoms, in particular C ₁₀ -C ₂₂ -alkyldimethylcarboxymethylbetaine and CιτC ₁₇ - alkylamidopropyldimethylcarboxymethylbetaine. Furthermore, the use of alkylamidoalkylamines, alkyl-substituted amino acids, acylated amino acids or biosurfactants as amphoteric surfactants in the cleaning agents which can be used according to the invention is conceivable.

The cleaning agents which can be used according to the invention can contain one or more amphoteric surfactants in amounts, based on the overall composition, of 0 to 5% by weight, greater than 0 to 5% by weight, preferably 0.01 to 3% by weight, in particular 0 Contain 1 to 1 wt .-%.

Means for adjusting the pH

To reduce the pH of cleaning agents, the agents can also be acidic

Have salts or slightly alkaline salts. In this case, preference is given to component bisulfates and / or bicarbonates or organic polycarboxylic acids, which can also be used at the same time as builder substances. The use of citric acid is particularly preferred.

builders

The cleaning agents which can be used according to the invention can contain, as builders or builders, all builders customarily used in cleaning agents, in particular thus zeolites, silicates, carbonates, soda, organic cobuilders and also the phosphates. To avoid particulate residues on textiles, it is particularly advantageous to use builders which are completely water soluble, such as soda or the like. Suitable crystalline, layered sodium silicates have the general formula NaMSi _x O _{2x +} ι H ₂ O, where M is sodium or hydrogen, x is a number from 1, 9 to 4 and y is a number from 0 to 20 and preferred values for x 2, 3 or 4. Preferred crystalline layered silicates of the formula given are those in which M represents sodium and x assumes the values 2 or 3. In particular, both β- and δ-sodium disilicate Na ₂ Si ₂ O ₅ ^• yH ₂ O are preferred.

Amorphous sodium silicates with a Na ₂ O: SiO ₂ modulus from 1: 2 to 1: 3.3, preferably from 1: 2 to 1: 2.8 and in particular from 1: 2 to 1: 2.6 can also be used. Amorphous silicates are particularly preferred.

A usable finely crystalline, synthetic and bound water-containing zeolite is preferably zeolite A and / or P. As zeolite P, zeolite ^MAP® (commercial product from Crosfield) is particularly preferred. However, zeolite X and mixtures of A, X and / or P are also suitable. Commercially available and can preferably be used in the context of the present invention, for example a co-crystallizate of zeolite X and zeolite A (about 80% by weight of zeolite X) ), which is sold by CONDEA Augusta SpA under the brand name VEGOBOND AX ^® and the formula: nNa ₂ O ^• (1-n) K ₂ O ^■ AI ₂ O ₃ ^• (2 - 2.5) SiO ₂ ^• ( 3.5 - 5.5) H ₂ O, corresponds.

Suitable zeolites have an average particle size of less than 10 μm (volume distribution; measurement method: Coulter Counter) and preferably contain 18 to 22% by weight, in particular 20 to 22% by weight, of bound water. It is of course also possible to use the generally known phosphates as builder substances, provided that such use should not be avoided for ecological reasons. The sodium salts of orthophosphates, pyrophosphates and in particular tripolyphosphates are particularly suitable. .

Organic cobuilders which can be used in the cleaning agents according to the invention are, in particular, polycarboxylates / polycarboxylic acids, polymeric polycarboxylates, aspartic acid, polyacetals, dextrins, other organic cobuilders (see below) and phosphates. These classes of substances are described below.

Usable organic builders are, for example, the polycarboxylic acids which can be used in the form of their sodium salts, polycarboxylic acids being understood to mean those carboxylic acids which carry more than one acid function. For example, these are citric acid, adipic acid, succinic acid, glutaric acid, malic acid, tartaric acid, maleic acid, fumaric acid, sugar acids, aminocarboxylic acids, nitrilotniacetic acid (NTA), as long as such use is not objectionable for ecological reasons, and mixtures of these. Preferred salts are the salts of polycarboxylic acids such as citric acid, adipic acid, succinic acid, glutaric acid, tartaric acid, sugar acids and mixtures of these.

The acids themselves can also be used. In addition to their builder effect, the acids typically also have the property of an acidifying component and thus also serve to set a lower and milder pH value of cleaning agents. Citric acid, succinic acid, glutaric acid, adipic acid, gluconic acid and any mixtures thereof can be mentioned in particular.

Polymeric polycarboxylates are also suitable as builders; these are, for example, the alkali metal salts of polyacrylic acid or polymethacrylic acid, for example those with a relative molecular weight of 500 to 70,000 g / mol.

For the purposes of this document, the molecular weights given for polymeric polycarboxylates are weight-average molecular weights M _{w of} the particular acid form, which were determined in principle by means of gel permeation chromatography (GPC), a UV detector being used. The measurement was made against an external polyacrylic acid standard, which provides realistic molecular weight values due to its structural relationship with the polymers investigated. This information differs significantly from the molecular weight information for which polystyrene sulfonic acids are used as standard. The molecular weights measured against polystyrene sulfonic acids are generally significantly higher than the molecular weights given in this document.

Suitable polymers are, in particular, polyacrylates, which preferably have a molecular weight of 2,000 to 2,000 g / mol. Because of their superior solubility, the short-chain polyacrylates with molecular weights from 2000 to 10000 g / mol, and particularly preferably from 3000 to 5000 g / mol, can in turn be preferred from this group.

Also suitable are copolymeric polycarboxylates, in particular those of acrylic acid with methacrylic acid and of acrylic acid or methacrylic acid with maleic acid. Copolymers of acrylic acid with maleic acid which contain 50 to 90% by weight of acrylic acid and 50 to 10% by weight of maleic acid have proven to be particularly suitable. Their relative molecular weight, based on free acids, is generally 2,000 to 70,000 g / mol, preferably 20,000 to 50,000 g / mol and in particular 30,000 to 40,000 g / mol.

Biodegradable polymers of more than two different monomer units are also particularly preferred, for example those which contain salts of acrylic acid and maleic acid as well as vinyl alcohol or vinyl alcohol derivatives as monomers or those which contain salts of acrylic acid and 2-alkylallylsulfonic acid and sugar derivatives as monomers ,

Further preferred copolymers are those which preferably have acrolein and acrylic acid / acrylic acid salts or acrolein and vinyl acetate as monomers.

Also to be mentioned as further preferred builder substances are polymeric aminodicarboxylic acids, their salts or their precursor substances. Polyaspartic acids or their salts and derivatives are particularly preferred which, in addition to cobuilder properties, also have a bleach-stabilizing effect. Other suitable builder substances are polyacetals, which can be obtained by reacting dialdehydes with polyolcarboxylic acids which have 5 to 7 carbon atoms and at least 3 hydroxyl groups. Preferred polyacetals are obtained from dialdehydes such as glyoxal, glutaraldehyde, terephthalaldehyde and mixtures thereof and from polyol carboxylic acids such as gluconic acid and / or glucoheptonic acid.

I

Other suitable organic builder substances are dextrins, for example oligomers or polymers of carbohydrates, which can be obtained by partial hydrolysis of starches. The hydrolysis can be carried out by customary, for example acid or enzyme-catalyzed, processes. They are preferably hydrolysis products with average molar masses in the range from 400 to 500,000 g / mol. A polysaccharide with a dextrose equivalent (DE) in the range from 0.5 to 40, in particular from 2 to 30, is preferred, DE being a customary measure of the reducing action of a polysaccharide compared to dextrose, which has a DE of 100 , is. Both maltodextrins with a DE between 3 and 20 and dry glucose syrups with a DE between 20 and 37 as well as so-called yellow dextrins and white dextrins with higher molar masses in the range from 2000 to 30000 g / mol can be used.

The oxidized derivatives of such dextrins are their reaction products with oxidizing agents which are capable of oxidizing at least one alcohol function of the saccharide ring to the carboxylic acid function. A product oxidized at C _{6 of} the saccharide ring can be particularly advantageous.

A preferred dextrin is described in British patent application 94 19 091. The oxidized derivatives of such dextrins are their reaction products with oxidizing agents which are capable of oxidizing at least one alcohol function of the saccharide ring to the carboxylic acid function. Such oxidized dextrins and processes for their preparation are known, for example, from European patent applications EP-A-0 232 202, EP-A-0 427 349, EP-A-0 472 042 and EP-A-0 542 496 and international patent applications WO- A-92/18542, WO-A-93/08251, WO-A-94/28030, WO-A-95/07303, WO-A-95/12619 and WO-A-95/20608 are known. A product oxidized at C6 of the saccharide ring can be particularly advantageous. Oxydisuccinates and other derivatives of disuccinates, preferably ethylenediamine disuccinate, are further suitable cobuilders. Ethylene diamine N, N'-disuccinate (EDDS) is preferably used in the form of its sodium or magnesium salts. Also preferred in this context are glycerol disuccinates and glycerol trisuccinates, as described, for example, in US Pat. Nos. 4,524,009, 4,639,325, European Patent Application EP-A-0 150 930 and Japanese Patent Application JP 93 / 339896.

Further usable organic cobuilders are, for example, acetylated hydroxycarboxylic acids or their salts, which may optionally also be in lactone form and which contain at least 4 carbon atoms and at least one hydroxyl group and at most two acid groups. Such cobuilders are described, for example, in international patent application WO-A-95/20029.

Another class of substances with cobuilder properties are the phosphonates. These are, in particular, hydroxyalkane or aminoalkane phosphonates. Among the hydroxyalkane phosphonates, 1-hydroxyethane-1,1-diphosphonate (HEDP) is of particular importance as a cobuilder. It is preferably used as the sodium salt, the disodium salt reacting neutrally and the tetrasodium salt in an alkaline manner (pH 9). Preferred aminoalkane phosphonates are ethylenediaminetetramethylenephosphonate (EDTMP), diethylenetriaminepentamethylenephosphonate (DTPMP) and their higher homologues. They are preferably in the form of the neutral sodium salts, e.g. used as the hexasodium salt of EDTMP or as the hepta and octa sodium salt of DTPMP. HEDP is preferably used as the builder from the class of the phosphonates. The aminoalkanephosphonates also have a pronounced ability to bind heavy metals. Accordingly, especially if the cleaning agents also contain bleach, it may be preferred to use aminoalkanephosphonates, in particular DTPMP, or to use mixtures of the phosphonates mentioned for the preparation of the agents.

In addition, all compounds that are able to form complexes with alkaline earth metal ions can be used as cobuilders. Suitable polymeric polycarboxylates for the preparation of the center which can be used according to the invention! are, for example, the sodium salts of polyacrylic acid or polymethacrylic acid, for example those with a relative molecular weight of 800 to 150,000 (based on acid). Suitable copolymeric polycarboxylates are, in particular, those of acrylic acid with methacrylic acid and of acrylic acid or methacrylic acid with maleic acid. Copolymers of acrylic acid with maleic acid which contain 50 to 90% by weight of acrylic acid and 50 to 10% by weight of maleic acid have proven to be particularly suitable. Their relative molecular weight, based on free acids, is generally 5,000 to 200,000, preferably 10,000 to 120,000 and in particular 50,000 to 100,000.

Also particularly preferred for the production of the cleaning agents which can be used according to the invention are biodegradable polymers composed of more than two different monomer units, for example those which, according to DE-A-43 00 772, are salts of acrylic acid and maleic acid, as well as vinyl alcohol or vinyl alcohol derivatives, as monomers DE-C-42 21 381 contain as monomers salts of acrylic acid and 2-alkylallylsulfonic acid as well as sugar derivatives.

Further preferred copolymers are those which are described in the German patent applications' DE-A-43 03 320 and DE-A-44 17 734 and which preferably have acrolein and acrylic acid / acrylic acid salts or acrolein and vinyl acetate as monomers.

Further suitable builder substances for producing the cleaning agents which can be used according to the invention are oxidation products of carboxyl-containing polyglucosans and / or their water-soluble salts, as are described, for example, in international patent application WO-A-93/08251 or their preparation, for example, in international patent application WO-A-93 / 16110. Oxidized oligosaccharides according to German patent application DE-A-196 00 018 are also suitable.

Further builder substances suitable for producing the cleaning agents which can be used according to the invention are polyacetals, which are obtained by reacting dialdehydes with polyolcarboxylic acids which have 5 to 7 C atoms and at least 3 hydroxyl groups, for example as described in European patent application EP-A-0 280 223 can. Preferred polyacetals are made from dialdehydes such as glyoxal, Glutaraldehyde, terephthalaldehyde and mixtures thereof and from polyol carboxylic acids such as gluconic acid and / or glucoheptonic acid.

bleach

The cleaning agents can also contain bleaching agents. In the simplest case, it can be an aqueous hydrogen peroxide solution. Among the compounds which provide H ₂ O ₂ in water and which serve as bleaching agents, sodium perborate tetrahydrate and sodium perborate monohydrate are of particular importance. Further bleaching agents which can be used are, for example, sodium percarbonate, peroxypyrophosphates, citrate perhydrates and H ₂ O ₂ -producing peracid salts or peracids, such as perbenzoates, peroxophthalates, diperazelaic acid, phthaloiminoperacid or diperdodecanedioic acid.

Bleaching agents from the group of organic bleaching agents can also be used to produce the cleaning agents. Typical organic bleaching agents are the diacyl peroxides, such as dibenzoyl peroxide. Other typical organic bleaching agents are peroxy acids, examples of which include alkyl peroxy acids and aryl peroxy acids.

Chlorine or bromine-releasing substances can also be used as bleaching agents in the cleaning agents which can be used according to the invention. Suitable materials that release chlorine or bromine include, for example, heterocyclic N-bromo- and N-chloramides, for example trichloroisocyanuric acid, tribromoisocyanuric acid, dibromoisocyanuric acid and / or dichloroisocyanuric acid (DICA) and / or their salts with catio- such as potassium and sodium. Hydantoin compounds such as 1,3-dichloro-5,5-dimethylhydanthoin are also suitable.

The bleach content is preferably 0 to 25% by weight and in particular 1 to 20% by weight, based on the overall composition of the cleaning agent.

Bleach activators

In order to achieve an improved bleaching effect when cleaning at room temperature, bleach activators can be included.

Bleach activators for the preparation of the cleaning agents which can be used according to the invention can be compounds which, under perhydrolysis conditions, give aliphatic peroxocarboxylic acids with preferably 1 to 10 C atoms, in particular 2 to 4 C atoms, and / or optionally substituted perbenzoic acid. Substances are suitable which carry O- and / or N-acyl groups of the number of carbon atoms mentioned and / or optionally substituted benzoyl groups. Multi-acylated alkylenediamines, in particular tetraacetylethylenediamine (TÄED), acylated triazine derivatives, in particular 1,5-diacetyl-2,4-dioxohexahydro-1,3,5-triazine (DADHT), acylated glycolurils, in particular tetraacetylglycoluril (TAGU) are preferred. , N-acylimides, especially N-nonanoyl succinimide (NOSI), acylated phenol sulfonates, especially n-nonanoyl or isononanoyl oxybenzenesulfonate (n- or iso-NOBS), carboxylic acid anhydrides, especially phthalic anhydride, especially acylated polyhydric alcohols , Ethylene glycol diacetate and 2,5-diacetoxy-2,5-dihydrofuran.

In addition to the conventional bleach activators or in their place, so-called bleach catalysts can also be used for the production of cleaning agents which can be used according to the invention. These substances are bleach-enhancing transition metal salts or transition metal complexes such as, for example, Mn, Fe, Co, Ru or Mo salt complexes or carbonyl complexes. Mn, Fe, Co, Ru, Mo, Ti, V and Cu complexes with N-containing tripod ligands as well as Co, Fe, Cu and Ru amine complexes are also used as bleaching catalysts usable.

Bleach activators which can be used to prepare the cleaning agents which can be used according to the invention are also those from German patent applications DE-A-196 16 693 and DE- A-196 16 767 known enol esters as well as acetylated sorbitol and mannitol or their mixtures described in the European patent application EP-A-0 525 239 (SORMAN), acylated sugar derivatives, in particular pentaacetyl glucose (PAG), pentaacetyl fructose, tetraacetylxylose and octaacetyl lactose and acetone optionally N-alkyl-glucamine and gluconolactone, and / or N-acylated lactams, for example N-benzoylcaprolactam, which are known from international patent applications WO-A-94/27970, WO-A-94/28102, WO-A-94 / 28103, WO-A-95/00626, WO-A-95/14759 and WO-A-95/17498 are used. The hydrophilically substituted acylacetals known from German patent application DE-A-196 16 769 and the acyl lactams described in German patent application DE-A-196 16 770 and international patent application WO-A-95/14075 are also preferred for the preparation of the cleaning agents that can be used according to the invention. Also, the conventional known from German patent application DE-A-4443 177 known combinations bleach ^activators, can be used for the preparation of the medium according to the invention can be used cleaning.

Conventional foam inhibitors can also be added to the cleaning agents which can be used according to the invention. Suitable foam inhibitors are, for example, soaps of natural or synthetic origin, which have a high proportion of C ₁₈ -C ₂₄ fatty acids. Suitable non-surfactant-like foam inhibitors are, for example, organopolysiloxanes and their mixtures with microfine, possibly signed silica, and paraffins, waxes, microcrystalline waxes and their mixtures with signed silica or bistearylethylenediamide.

enzymes

Suitable enzymes for the preparation of the cleaning agents are, in particular, those from the classes of hydrolases such as proteases, esterases, lipases or lipolytically active enzymes, amylases, glycosyl hydrolases and mixtures of the enzymes mentioned. All of these hydrolases help to remove stains such as protein, fat or starchy stains.

Oxidoreductases can also be used for bleaching. Particularly suitable for the production of the cleaning agents are those derived from bacterial strains or fungi such as Bacillus subtilis, Bacillus licheniformis, Streptomyceus griseus, Coprinus Cinereus and Humicola insolens as well as enzymatic active ingredients obtained from their genetically modified variants. Proteases of the subtilisin type and in particular proteases obtained from Bacillus lentus are preferred. Enzyme mixtures, for example, from protease and amylase or protease and lipase or lipolytic enzymes or from protease, amylase and lipase or lipolytic enzymes or protease, lipase or lipolytic enzymes, but especially protease and / or lipase-containing enzymes Mixtures or mixtures with lipolytically active enzymes of particular interest. Examples of such lipolytically active enzymes are the known cutinases. Peroxidases or oxidases have also proven to be suitable in some cases. Suitable amylases include in particular alpha-amylases, iso-amylases, pullulanases and pectinases. Oxireductases are also suitable.

In addition to the enzymes mentioned above, cellulases can also be used for the production of the cleaning agents. By removing pilling and microfibrils, cellulases and other glycosyl hydrolases can help maintain color and increase the softness of the textile. Cellobiohydrolases, endoglucanases and glucosidases, which are also called cellobiases, or mixtures thereof, are preferably used as cellulases. Since different cellulase types differ in their CMCase and avicelase activities, the desired activities can be set by targeted mixtures of the cellulases.

The proportion of the enzymes or enzyme mixtures can be, for example, about 0.1 to 5% by weight, preferably 0.5 to about 4.5% by weight, based on the total weight of the detergent composition.

enzyme stabilizers

In addition to phosphonates, the cleaning agents can also contain further enzyme stabilizers. For example, the cleaning agents can contain sodium formate. It is also possible to use proteases which are stabilized with soluble calcium salts and a calcium content of preferably about 1.2% by weight, based on the enzyme. In addition to calcium salts, magnesium salts also serve as stabilizers. However, the use of boron compounds, for example boric acid, boron compounds, is particularly advantageous. oxide, borax and other alkali metal borates such as the salts of orthoboric acid (H3BO3), metaboric acid (HBO2) and pyroboric acid (tetraboric acid H2B4O7).

Verqrauungsinhibitoren

The cleaning agents can also contain graying inhibitors. Graying inhibitors have the task of keeping the dirt detached from the fibers suspended in the liquor and thus preventing the dirt from being re-absorbed. Water-soluble colloids of mostly organic nature are suitable for this, for example the water-soluble salts of polymeric qarboxylic acids, glue, gelatin salts of ether carboxylic acids or ether sulfonic acids of starch or cellulose or salts of acidic sulfuric acid esters of cellulose or starch. Water-soluble polyamides containing acidic groups are also suitable for this purpose. Soluble starch preparations and starch products other than those mentioned above can also be used, e.g. degraded starch, aldehyde starches, etc., polyvinylpyrrolidone can also be used. However, cellulose ethers, such as carboxymethyl cellulose (sodium salt), methyl cellulose, hydroxyalkyl cellulose and mixed ethers, such as methylhydroxyethyl cellulose, methyl hydroxypropyl cellulose, methyl carboxymethyl cellulose and mixtures thereof, and also polyvinylpyrrolidone are preferably used in the cleaning agents which can be used according to the invention.

Dirt-repellent substances

In addition, dirt-repellent substances can be used to produce the cleaning agents, which have a positive influence on the oil and fat washability from textiles (so-called soil repellents). The preferred oil and fat-dissolving components include, for example, nonionic cellulose ethers such as methyl cellulose and methyl hydroxypropyl cellulose with a proportion of methoxyl groups from 15 to 30% by weight and of hydroxypropoxyl groups from 1 to 15% by weight, based in each case the nonionic cellulose ether, and the polymers of phthalic acid and / or terephthalic acid or their derivatives known from the prior art, in particular polymers of ethylene terephthalates and / or polyethylene glycol terephthalates or anionically and / or nonionically modified derivatives thereof.

Optical brighteners

These substances, which are also called "whiteners", can be used to manufacture the cleaning agents. Optical brighteners are organic dyes that unite Convert part of the invisible UV radiation from sunlight into longer-wave blue light. The emission of this blue light complements the "gap" in the light reflected by the textile, so that a textile treated with an optical brightener appears whiter and brighter to the eye. Since the action mechanism of brighteners presupposes that they are drawn onto the fibers, a distinction is made, for example, depending on the “fibers to be dyed”

Brighteners for cotton, polyamide or polyester fibers The commercially available brighteners suitable for the production of cleaning agents essentially include five ι ι

Structural groups, namely the stilbene, diphenylstilbene, coumarin-quinoline, diphenyl-pyrazoline group and the group of the combination of benzoxazole or benzimidazole with conjugated systems. An overview of common brighteners can be found, for example, in G. Jakobi, A. Löhr "Detergents and Textile Washing", VCH-Verlag, Weinheim, 1987, pages 94 to 100. Suitable are, for example, salts of 4,4'-bis [(4-anilino-6-morpholino-s-triazine-2-yl) amino] -stilbenr2,2'-disulfonic acid or compounds of similar structure which instead of the morpholino- Group carry a diethanolamino group, a methylamino group, anilino group or a 2-methoxyethylamino group. Brighteners of the substituted diphenylstyryl type may also be present, for example the alkali salts of 4,4'-bis (2-sulfostyryl) diphenyl, 4,4'-bis (4-chloro-3-sulfostyryl) diphenyl, or 4- (4-chlorostyryl) -4 '- (2-sulfostyryl) diphenyl. Mixtures of the brighteners mentioned above may be used. ¹

fragrances

Fragrances can be added to the cleaning agents that can be used according to the invention in order to improve the aesthetic impression of the resulting agents and, in addition to the cleaning performance and the color impression, provide the consumer with a sensorically "typical and unmistakable" cleaning agent. Individual fragrance compounds, for example the synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type, can be used as perfume oils or fragrances. Fragrance compounds of the ester type are, for example, benzyl acetate, phenoxyethyl isobutyrate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinyl acetate, phenylethyl acetate, linalyl benzoate, benzyl formate, ethyl methylphenyl glycinate, allyl cyclohexyl propylate propylateionate. The ethers include, for example, benzylethyl ether, the aldehydes include, for example, the linear alkanals with 8-18 C atoms, citral, citronellal, citronellyloxyacetaldehyde, cyclamenaldehyde, hydroxycitronellal, lilial and bourgeonal, the ketones include, for example, the jonones, oc-isomethylionone and methyl cedryl ketone, to the alcohols anethole, citronellol, eugenol, geraniol, linalool, phenylethyl alcohol and

Terpineol, the hydrocarbons mainly include terpenes such as limes and pines. However, preference is given to using mixtures of different odoriferous substances for producing the cleaning agents which can be used according to the invention and which together produce an appealing fragrance. Such perfume oils can also contain natural fragrance mixtures as are available from plant sources, e.g. Pine, citrus, jasmine, patchouly, rose or ylang-ylang oil. Also suitable are muscatel, sage oil, chamomile oil, clove oil, lemon balm oil, mint oil, cinnamon leaf oil, linden blossom oil, juniper oil, vetiver oil, olibanum oil, galbanum oil and labdanum oil as well as orange blossom oil, neroliol, orange peel oil and sandalwood oil.

dyes

In order to improve the aesthetic impression of the cleaning agents that can be used according to the invention, the cleaning agents can be colored with suitable dyes. Preferred dyes, the selection of which is not difficult for the person skilled in the art, have a high. Storage stability and insensitivity to the other ingredients of the cleaning agents and to light as well as no pronounced substantivity to textile fibers so as not to stain them.

Preferred for the production of the cleaning agents which can be used according to the invention are all coloring agents which can be oxidatively destroyed during cleaning, as well as mixtures thereof with suitable blue dyes, so-called blue toners. It has proven to be advantageous to use colorants which are soluble in water or in liquid organic substances at room temperature. For example, anionic colorants, for example anionic nitroso dyes, are suitable. One possible dye is, for example, naphthol green (Color Index (CI) Part 1: Acid Green 1; Part 2: 10020)., That is as a commercial product, for example as Basacid ^® Green 970 from BASF, Ludwigshafen available, as well as mixtures thereof with suitable blue dyes. Other colorants are Pigmosol ^® Blue 6900 (Cl 74160), Pigmosol ^® Green 8730 (Cl 74260), Basonyl ^® Red 545 FL (Cl 45170), Sandolan ^® Rhodamine EB400 (Cl 45100), Basacid ^® Yellow 094 (Cl 47005), Sicovit ^® Patentblau 85 E 131 (Cl 42051), Acid Blue 183 (CAS 12217-22-0, Cl Acidblue 183), Pigment Blue 15 (Cl 74160), Supranol ^® Blau GLW (CAS 12219-32-8, Cl Acidblue 221 ), Nylosan ^® Yellow N-7GL SGR (CAS 61814-57-1, Cl Acidyellow 218) and / or Sandolan ^® Blue (Cl Acid Blue 182, CAS 12219-26-0). When choosing the colorant, it must be noted that the colorants do not have too strong an affinity for the textile surfaces and especially for synthetic fibers. At the same time, when choosing suitable colorants, it must also be taken into account that colorants have different stabilities against oxidation. In general, water-insoluble colorants are more stable to oxidation than water-soluble colorants. Depending on the solubility and thus also on the sensitivity to oxidation, the concentration of the colorant in the cleaning agents varies. For highly soluble dyes, for example, the above-mentioned Basacid ^® Green or the above-mentioned Sandolan ^® Blue are typically chosen dyestuff concentrations in the range of some 10 ^"2 to ^{10" 3} wt .-%, each based on the total detergent, , In the due to their brilliance particularly preferred, but are less readily water-soluble pigment dyes, for example the above-mentioned Pigmosol ^® ATTO-dyes, the appropriate concentration of the colorant is in detergents, however, typically a few 10 ^"3 to ^{10" 4} wt .-%, based on all the detergent.

In principle, however, any liquid, foam-like or gel-like cleaning composition is suitable which, on the one hand, has excellent dirt removal properties and, on the other hand, leaves little or no visible residue on the treated fabric.

If the non-ionic surfactant is used alone, there may be a risk that it will leave an oily residue on the treated tissue. Therefore combinations of nonionic and anionic surfactants are preferred.

For example, the combination of non-ionic and anionic surface-active substances results in detergent systems with preferred critical micelle concentrations (CMC), which give the agent dirt-removing properties.

In a preferred embodiment, the nonionic surfactant is an ethoxylated alcohol with a chain length of 12- 15 carbon atoms and 3-7 moles of ethylene oxide, preferably 3 to 5 moles of ethylene oxide. Examples of such preferred nonionic surface-active substances include the commercially available products Neodol 25-3, Neodol 23-3 (manufacturer: Shell Corp.), Surfonic L24-3, Surfonic L24-4 and Surfonic L1270-2 (manufacturer: Huntsman Corp. .) in question.

In the compositions which can be used according to the invention, it is desirable for the proportion of the nonionic surface-active substance to be between 0.05% by weight and 1.0% by weight, in each case based on the total composition.

In the context of the invention, a nonionic surfactant can be used in conjunction with at least one of the aforementioned categories of anionic surfactants.

Cleaning agents based on organic solvents and also those based on water are also suitable according to the invention. The agents are applied as a liquid, gel or foam and should contain at least 70% by weight, preferably at least 80% by weight, of volatile constituents. Examples of such cleaning agents can be found in the relevant specialist literature.

Solvent-based cleaning agents, also known as stain water, are mostly water-free and generally contain no surfactants. The main solvents used are alcohols, petrol, chlorinated hydrocarbons, butyl acetate and similar volatile compounds, either alone or in mixtures. Agents of this type are particularly suitable for removing grease stains and stains from felt-tip and ballpoint pens. Cleaning agents in gel form consist of a mixture of very finely divided adsorbent such as silica or starch and organic solvents, especially gasoline and chlorinated hydrocarbons. These agents are also particularly suitable for grease and ballpoint stains.

Glycol ethers are preferably used as the sole organic solvent or as the main constituent of a mixture of organic solvents. These materials are lower (alkoxy) - or lower (alkoxy) lower (alkoxy) ether of ethanol or isopropanol. Some glycol ethers are available under the trade names Arcosolv ^® (Arco Chemical Co.) or Qellosolve ^® , Carbitol ^® or Propasol ^® (Union Carbide Corp.); these also include, for example, ButylCarbitol ^® , HexylCarbitol ^® , MethylCarbitol ^® , and Carbitol ^® itself, (2- (2-ethoxy) ethoxy) ethanol. The choice of the glycol ether can easily be made by the person skilled in the art on the basis of its volatility, water solubility, its weight percentage in the total dispersion and the like. Pyrrolidone solvents such as N-alkylpyrrolidone, for example N-methyl-2-pyrrolidone or NC ₈ -C ₁₂ -alkylpyrrolidone, or 2-pyrrolidone can also be used. Also preferred as the sole solvent or as part of a solvent mixture are glycerol derivatives, in particular glycerol carbonate. ,

The alcohols which can be used as a cosolvent in the present invention include liquid polyethylene glycols with a low molecular weight, for example polyethylene glycols with a molecular weight of 200, 300, 400 or 600. Other suitable cosolvents are other alcohols, for example (a) lower Alcohols such as ethanol, propanol, isopropanol and n-butanol, (b) ketones such as acetone and methyl ethyl ketone, (c) C ₂ -C ₄ polyols such as a diol or a triol, for example ethylene glycol, propylene glycol, glycerol or mixtures from that. From the class of diols, 1,2-octanediol is particularly preferred.

Other organic solvents which are suitable in principle are conventional chlorinated solvents, as are usually known from commercial chemical cleaning. These include the di- to tetrachlorinated derivatives of methane, the di- to pentachlorinated derivatives of ethane, the mono- to trichlorinated derivatives of cyclohexane and monochlorobenzene. Specific examples are carbon tetrachloride, methylene chloride, 1,1-dichloroethane, 1,2-dichloroethane, 1,1,1-trichloroethane, 1,1,2-trichloroethane, trichloroethene, 1,1,2,2-tetrachloroethane, tetrachloroethene , Pentachloroethane, chlorochlorocyclohexane, 1,4-dichlorocyclohexane, monochlorobenzene and mixtures of the above. However, these chlorinated hydrocarbons are less preferred for household use.

Organic solvents which are suitable for causing the agents to have two phases are, for example, hydrocarbons and alkyl ethers. Particularly preferred hydrocarbons are those which have a boiling point above 150 ° C. and preferably above 180 ° C. Particularly preferred multi-phase and in particular two-phase liquid and sprayable textile cleaning agents contain paraffins or isoparaffins with a boiling range between 200 and 300 ° C. In particular Isoparaffins are suitable as the only organic in the multi-phase cleaning agents

Solvents can be used, but it can be an advantage if the agents not only have hydrocarbons as organic solvents, but also one of the above-mentioned water-miscible organic solvents.

Particularly suitable alkyl ethers are dialkyl ethers, especially C ₆ -C ₁₈ alkyl ethers, with particular preference for C ₈ -C ₁₂ alkyl ethers, for example dioctyl ether.

Other organic solvents that also have an excellent cleaning action include butoxypropoxypropanols (BPP), which are commercially available as a mixture of several isomers. Since BPP are not completely miscible with water, they are particularly suitable for use in multi-phase cleaning agents. However, if BPP is to be used in single-phase, water-based cleaning agents, it is necessary to use additional emulsifiers. For examples of possible emulsifiers, reference is made in full to the disclosure of WO 96/30580.

Water-based cleaning agents preferably contain tensides in amounts of about 0.4 to about 10 percent by weight, and in addition mostly additions of solvents which are readily soluble in water, such as lower alcohols, additions of salts, such as phosphates and borax, and other cleaning agents. Such means are not only offered for individual types of stains, but are often advertised as universal means. They can be used directly as a liquid or, because of the easier spreadability, can be applied as a foam.

Stain-removing agents suitable according to the invention contain at least one organic liquid, selected from the group comprising gasoline, benzine, aromatics, trichloroethane, trichlorethylene, methylene chloride.

In preferred embodiments that can be used according to the invention, a stain removal agent can contain at least one organic liquid and at least one surfactant, in particular nonionic surfactant. A stain removing agent preferred according to the invention has the following composition:

example 1

- surfactants 0.05 - 10% by weight

- polymeric additives 0 - 0.1% by weight

- solvent 0 - 30% by weight

- usual additives 0 - 5% by weight

- rest of water

Anionic and nonionic surfactants are particularly suitable as surfactants for this agent. Alkyl sulfates, alkyl sarcosides and alkyl sulfosuccinates with long-chain alkyl radicals which contain 8 to 18 carbon atoms are used as anionic surfactants. Also suitable are alkanesulfonates with 12 to 18 carbon atoms, monoalkyl polyethylene glycol ether sulfates with 10 to 20 carbon atoms in the alkyl part and 1 to 6 ethylene glycol units in the molecule, and also soaps, salts of fatty acid cyanamides or salts of long-chain ether carboxylic acids. The anionic surfactants are preferably used in the form of the sodium salts. Sodium alkyl sulfates, sodium alkyl sarcosides and sodium alkyl sulfosuccinates, of which in turn sodium alkyl sulfates with chain lengths of 12 to 16 carbon atoms, in particular technical sodium lauryl sulfate, can also be used as anionic surfactants.

The addition products of 1 to 30, preferably 4 to 15, moles of ethylene oxide and 1 mole of a long-chain compound having 10 to 20 carbon atoms from the group of alcohols, alkylphenols, carboxylic acids and carboxamides are suitable as nonionic surfactants. The addition products of ethylene oxide with long-chain, primary or secondary alcohols, such as fatty alcohols or oxo alcohols with 10 to 20 C atoms and with mono- or dialkylphenols with 6 to 14 C atoms in the alkyl groups, are preferred.

The stain-removing effect of the surfactants can be significantly improved by adding certain water-soluble polymers. These polymers, which are added in small amounts up to about 0.1% by weight, are preferably the following types of compounds: polyethylene oxides with molecular weights between 200,000 and 5,000,000, nonionic cellulose ethers, such as methyl cellulose and hydroxyethyl cellulose, Polyvinyl alcohol, polyacrylamide and homopolymers of acrylic acid, methacrylic acid and maleic acid and copolymers of these compounds with suitable comonomers. The amount of polymer used depends on the chemical composition of the polymer and can range up to a lower limit of about 0.001% by weight, based on the total agent. For example, the polyethylene oxides mentioned are preferably used in amounts between 0.001 and 0.01% by weight; the other polymers preferably in amounts between 0.01 and 0.05% by weight, based on the total agent.

Although good results in stain removal can be achieved even without the use of organic solvents, not least because of the cleaning-enhancing action of the polymers, the agents can contain up to 30% by weight of organic solvents to enhance the cleaning action, in particular grease stains and stains from Ballpoint or felt pens included. Both water-immiscible and water-miscible and limited water-soluble solvents are suitable, for example alcohols with 3 to 5 C atoms, acetone, glycol ethers with up to 10 C atoms and gasolines with boiling ranges from 100 to 280 ° C as well as terpenes in smaller quantities. Alcohols with 2 and 3 carbon atoms and glycol ethers with 4 to 7 carbon atoms, in particular ethanol, isopropanol, dipropylene glycol monomethyl ether and propylene glycol monoisobutyl ether, are particularly preferred. The total solvent content is preferably between 5 and 25% by weight, based on the total agent.

The stain-removing agents can furthermore contain customary additives, such as salts, preservatives, perfume, thickeners and insoluble polymers with minimal film-forming temperatures above 70 ° C., for example polymethyl methacrylate. The amount of these substances is usually not more than 5% by weight, preferably between 0.01 and 2% by weight.
