Description

Liquid detergent with a catechol compound

The present invention relates to the use of catechol compounds which are used together with (preferably concentrated), liquid detergent compositions to improve the washing and cleaning performance.

While the formulation of powdered detergents and cleaning agents containing bleach now no longer poses any problems, the formulation of stable liquid detergents and cleaning agents containing bleach continues to be a problem. Because of the usually lack of bleach in liquid detergents and cleaning agents, such Soiling, which is normally removed in particular due to the bleaching agent contained, is correspondingly frequently only removed in an inadequate manner. A similar problem also exists for bleach-free color detergents in which the bleach is omitted in order to protect the dyes in the textile and prevent them from fading. In the absence of bleach, it is aggravated that instead of removing the so-called bleachable stains, which are normally at least partially removed by the use of bleaching agents based on peroxygen, on the contrary, the washing process often leads to an intensification and / or deterioration in the removability of the stain, This should not least be attributed to initiated chemical reactions, which may consist, for example, in the polymerisation of certain dyes contained in the soiling.

Such problems occur in particular with soiling that is polymerizable

Contain substances. The polymerizable substances are mainly polyphenolic dyes, preferably flavonoids, in particular from the class of anthocyanidins or anthocyanins. The soiling can in particular be caused by

Food products or beverages have been caused that contain appropriate colorants. The soiling can be, in particular, stains from fruits or vegetables or also red wine stains, which in particular contain polyphenolic dyes, especially those from the class of anthocyanidins or anthocyanins.

International patent application WO 201 1/023716 A1 describes the use of

Gallic acid esters such as propyl gallate in detergents and cleaning agents for improved removal of soils which contain polymerizable substances are known.

The international patent application WO 2013/092263 A1 relates to the improvement of the performance of detergents and cleaning agents through the use of oligohydroxybenzoic acid amides. The German patent applications DE 102016214660 A1 and DE 102014222833 relate to the use of dihydroxy terephthalic acid derivatives in detergents and cleaning agents to improve the washing or cleaning performance. The detergents and cleaning agents in these publications have an alkaline pH.

It has been shown that when catechol derivatives are incorporated into liquid, alkaline, aqueous compositions, a red to brown discoloration of the

Composition forms. This discoloration is undesirable.

Surprisingly, it was found that by using at least one

selected catechol compound, in particular from the group of

Dihydroxy terephthalic acid diamides, the washing or cleaning performance of liquid (especially concentrated) detergents, particularly with regard to bleachable soiling, can be significantly improved. If said catechol compound is incorporated into an aqueous composition with a pH of at most pH 7, undesirable rust-brown to red discoloration of the detergents is prevented at the same time. The discoloration is particularly pronounced in the case of liquid surfactant compositions containing alkanolamine. In order nevertheless to ensure an alkaline pH value of the wash liquor which is favorable for the washing process, the use of a multicomponent detergent is preferred, which comprises said liquid, acidic catechol derivative composition in combination with a liquid, alkaline, alkanolamine-containing composition.

A first subject of the present invention is therefore the use of at least one catechol compound of the formula (I)

Such exchanges are usually carried out at the DNA level via mutations of individual base pairs (see above). “R320K” means, for example, that the reference enzyme at position 320 contains the amino acid arginine, while the variant under consideration at the position that can be homologated via the amino acid lysine "320K" means that any, that is to say usually a naturally prescribed, amino acid at a position which corresponds to position 320 is replaced by a lysine which is located at precisely this point in the present molecule. "R320K, L “means that the amino acid arginine at position 320 is replaced by lysine or leucine. And "R320X" means that the amino acid arginine in position 320 is replaced by any other amino acid.

In principle, the amino acid exchanges according to the invention designated by the present application are not limited to the fact that they are the only exchanges in which the variant in question differs from the wild-type molecule. It is state of the art known that the advantageous properties of individual point mutations can complement each other. Thus, embodiments of the present invention include all variants which, in addition to other exchanges with the wild-type molecule, also have the exchanges according to the invention.

Furthermore, in principle it does not matter in what order the amino acid exchanges in question have been carried out, that is to say whether a corresponding point mutant

is further developed according to the invention or, for example, a variant according to the invention is first generated from a wild-type molecule, which is further developed in accordance with other teachings found in the prior art. Several exchanges can also be carried out simultaneously in a mutagenesis approach, for example the invention and others together.

It is preferred according to the invention if at least one protease is contained as the enzyme. A protease is an enzyme that cleaves peptide bonds by hydrolysis. Each of the class E.C. 3.4 falls according to the invention (including each of the thirteen subclasses). The EC number corresponds to the Enzyme Nomenclature 1992 of the NC-IUBMB, Academic Press, San Diego, California, including supplements 1 to 5, published in Eur. J. Biochem. 1994, 223, 1-5; Eur. J. Biochem. 1995, 232, 1-6; Eur. J. Biochem. 1996, 237, 1-5; Eur. J. Biochem. 1997, 250, 1-6; and Eur. J. Biochem. 1999, 264, 610-650.

Subtilase names a subset of the serine proteases. The serine proteases or serine peptidases are a subset of the proteases that have serine in the active center of the enzyme that forms a covalent adduct with the substrate. Furthermore, the subtilases (and the

Serine proteases) characterized in that, in addition to said serine with histidine and aspartame, they have two further amino acid residues in the active center. The subtilases can be divided into 6 subclasses, namely the subtilisin family, the thermitase family, the proteinase K family, the family of lantibiotic peptidases, the kexin family and the pyrolysine family. The proteases which are preferably excluded or preferably contained in reduced amounts as part of the compositions according to the invention are endopeptidases (EC 3.4.21).

According to the invention, “protease activity” is present if the enzyme has proteolytic activity (EC 3.4). Different types of protease activity are known: The three main types are:

Trypsin-like, with cleavage of the amide substrate according to the amino acids Arg or Lys at P1; Chymotrypsin-like, with cleavage after one of the hydrophobic amino acids at P1; and elastase-like, with cleavage of the amide substrate according to Ala at P1.

The protease activity can be determined by the method described in Tenside, Volume 7 (1970), pp. 125-132. Accordingly, it is given in PE (protease units). The Protease activity of an enzyme can be carried out according to standard methods, such as in particular using BSA as substrate (bovine albumin) and / or using the AAPF method.

Surprisingly, it was found that a protease of the type of the alkaline protease from Bacillus lentus DSM 5483 or a protease sufficiently similar to this (based on the sequence identity), which exhibits several of these changes in combination, is particularly suitable for use in and in the liquid surfactant composition according to the invention is advantageously improved stabilized. Advantages of using this protease thus arise in particular with regard to washing performance and / or stability.

The identity of nucleic acid or amino acid sequences is determined by a sequence comparison. This sequence comparison is based on the BLAST algorithm established and commonly used in the prior art (cf. for example Altschul, SF, Gish, W., Miller, W., Myers, EW & Lipman, DJ (1990) "Basic local alignment search tool "J. Mol. Biol. 215: 403-410, and Altschul, Stephan F., Thomas L. Madden, Alejandro A. Schaffer, Jinghui Zhang, Hheng Zhang, Webb Miller, and David J. Lipman (1997):" Gapped BLAST and PSI-BLAST: a new generation of protein database search programs "; Nucleic Acids Res., 25, S.3389-3402) and is principally done in that similar sequences of nucleotides or amino acids in the nucleic acid or amino acid sequences are assigned to one another become. A tabular assignment of the relevant positions is called alignment. Another algorithm available in the prior art is the FASTA algorithm. Sequence comparisons (alignments), in particular multiple sequence comparisons, are created using computer programs. The Clustal series (cf. for example Chenna et al. (2003): Multiple sequence alignment with the Clustal series of programs. Nucleic Acid Research 31, 3497-3500), T-Coffee (cf. for example Notredame et al . (2000): T-Coffee: A novel method for multiple sequence alignments. J. Mol. Biol. 302, 205-217) or programs based on these programs or algorithms. In the present patent application, all sequence comparisons (alignments) were carried out with the computer program Vector NTI® Suite 10.3 (Invitrogen Corporation, 1600 Faraday Avenue, Carlsbad, California, USA) with the specified ones

Standard parameters created, whose AlignX module for sequence comparisons is based on ClustalW.

Such a comparison also allows a statement about the similarity of the compared sequences to one another. It is usually given in percent identity, that is to say the proportion of identical nucleotides or amino acid residues in the same positions or in an alignment corresponding to one another. The broader concept of homology also includes conserved amino acid exchanges in amino acid sequences, i.e. amino acids with similar chemical activity, since these usually have similar chemical functions within the protein

Practice activities. Therefore, the similarity of the compared sequences can also be given as percent homology or percent similarity. Identity and / or homology information can be applied to entire polypeptides or genes or only to individual areas. Homologous or identical regions of different nucleic acid or amino acid sequences are therefore defined by matches in the sequences. Such areas often have identical functions. They can be small and contain only a few nucleotides or amino acids. Such small areas often have essential functions for the overall activity of the protein. It can therefore make sense to relate sequence matches only to individual, possibly small, areas. Unless otherwise stated, identity or homology information in the present application relates to the total length of the nucleic acid or amino acid sequence specified in each case.

The concentration of the protease in the liquid composition is from 0.001-0.1% by weight, preferably from 0.01 to 0.06% by weight, based on active protein.

The liquid surfactant compositions according to the invention (particularly preferably in addition to the protease) preferably contain at least one enzyme selected from α-amylase, cellulase, mannanase, lipase, pectate lyase as the enzyme.

In general, the enzymes contained in a composition according to the invention can be adsorbed on carriers and / or embedded in coating substances in order to protect them against premature inactivation.

Compositions according to the invention can be added to the enzymes obtained in any form established according to the prior art. This includes in particular the through

Granulation, extrusion or lyophilization obtained solid preparations, advantageously concentrated as possible, low in water and / or mixed with stabilizers. In an alternative dosage form, the enzymes can also be encapsulated, for example by

Spray drying or extrusion of the enzyme solution together with a, preferably natural polymer or in the form of capsules, for example those in which the enzymes are enclosed in a solidified gel, or in those of the core-shell type in which an enzyme-containing core with a Water, air and / or chemical impermeable protective layer is coated. Additional active ingredients, for example stabilizers, emulsifiers, pigments, bleaching agents or dyes, can additionally be applied in layers. Such capsules are made according to methods known per se, for example by Schüttei or

Roll granulation or applied in fluid-bed processes. Such granules are advantageously low in dust, for example by applying polymeric film formers, and are stable on storage due to the coating.

The liquid compositions preferably additionally contain at least one cellulase. A cellulase is an enzyme. Synonymous terms can be used for cellulases, in particular endoglucanase, endo-1, 4-beta-glucanase, carboxymethyl cellulase, endo-1, 4-beta-D-glucanase, beta-1, 4-glucanase, beta-1, 4-endoglucan hydrolase, cellulose dextrinase or avicelase. The decisive factor for whether an enzyme is a cellulase in the sense of the invention is its ability to hydrolize 1,4-β-D-glucosidic bonds in cellulose.

Ready-to-use cellulases (endoglucanases, EG) include, for example, the fungal cellulase preparation rich in endoglucanase (EG) or its preparation

The compositions according to the invention preferably contain mannanase in a total amount of 0.01 to, based on the total weight of the composition

1.0% by weight, in particular from 0.02 to 0.1% by weight.

Mannanase polypeptides from strains of the Thermoanaerobacter group, such as caldicellulose ruptor, are preferably suitable according to the invention. Mannanase polypeptides of the fungi Humicola or Scytalidium, in particular of the species Humicola insolens or Scytalidium thermophilum, can also be used in the context of the invention.

It is particularly preferred according to the invention if the compositions according to the invention as mannanase enzyme have at least one mannanase polypeptide from gram-positive alkalophilic strains of Bacillus, in particular selected from at least one member of the group from Bacillus subtilis, Bacillus ientus, Bacillus clausii, Bacillus agaradhaerens, Bacillus brevis, Bacillus stearothermophilus, Bacillus alkalophilus, Bacillus amyloliquefaciens, Bacillus coagulans, Bacillus circulans, Bacillus lautus, Bacillus thuringiensis, Bacillus cheniformis, and Bacillus sp., especially preferably selected from at least one representative of the group from Bacillus sp. 1633, Bacillus sp.

i) polypeptides comprising an amino acid sequence which is at least 90% (more preferably at least 90.5%, 91%, 91, 5%, 92%, 92.5%, 93%, 93.5%, 94%, 94 , 5%, 95%, 95.5%, 96%, 96.5%, 97%, 97.5%, 98%, 98.5%, 99.0%, 99, 1%, 99.2% , 99.3%, 99.4%, 99.5%, 99.6%, 99.7% or 99.8%) sequence identity to the polypeptide according to SEQ ID No.1 (cf.

Sequence listing from WO 99/64619), and

ii) polypeptides that are a fragment of (i).

It is again preferred if said preferred mannanase in a total amount of 0.01 to 1.0% by weight, in particular 0.02 to 0.1% by weight, in each case based on the total weight of the composition, in the composition according to the invention is included.

Particularly preferably, the liquid surfactant composition according to the invention contains, in addition to the preferred protease of the alkaline protease type from Bacillus lentus DSM 5483 or in addition to the protease which is sufficiently similar to this (based on the sequence identity) and which has several of these changes in combination, at least one a-amylase . a-Amylases (E.C. 3.2.1.1) hydrolyze as internal enzyme a-1, 4-glycosidic bonds of starch and starch-like polymers. This a-amylase activity is measured, for example, according to the applications WO 97/03160 A1 and GB 1296839 in KNU (Kilo Novo Units). 1 KNU stands for the amount of enzyme, the 5.25 g of starch (available from Merck, Darmstadt, Germany) per hour at 37 ° C., pH 5.6 and in the presence of 0.0043 M.

Calcium ions hydrolyzed. An alternative activity determination method is the so-called DNS method, which is described for example in the application WO 02/10356 A2. Then the oligosaccharides, disaccharides and glucose units released by the enzyme during the hydrolysis of starch are oxidized by oxidation of the reducing ends

Detected dinitrosalicylic acid (DNA). The activity is obtained in pmol of reducing sugars (based on maltose) per min and ml; this results in activity values in TAU. The same enzyme can be determined by different methods, the respective

Conversion factors may vary depending on the enzyme and must therefore be determined using a standard. You can roughly calculate that 1 KNU corresponds to approx. 50 TAU. Another activity determination method is measurement using the Quick-Start ^® test kit from Abbott, Abott Park, Illinois, USA. A preferred area of use of the liquid surfactant compositions according to the invention is in the cleaning of textiles. Because laundry detergents and cleaning agents for textiles mainly have alkaline pH values, a-amylases, which are active in the alkaline medium, are used in particular. These are produced and secreted by microorganisms, ie fungi or bacteria, especially those of the genera Aspergillus and Bacillus. Based on these natural enzymes, there is almost still one

unmanageable abundance of variants are available which have been derived via mutagenesis and which have specific advantages depending on the area of application.

Examples of this are the a-amylases from Bacillus licheniformis, from B. amyloliquefaciens and from B. stearothermophilus as well as their further developments for use in detergents or cleaning agents. The enzyme from B. licheniformis is available from Novozymes under the name Termamyl ^® and from Genencor under the name Purastar® ^® ST.

Further development products of this a-amylase are from Novozymes among the

Trade names Duramyl ^® and Termamyl ^® ultra, available from Genencor under the name Purastar ^® OxAm and from Daiwa Seiko Inc., Tokyo, Japan, as Keistase ^® . The a-amylase from B. amyloliquefaciens is marketed by Novozymes under the name BAN ^®, and variants derived from the alpha-amylase from B. stearothermophilus under the names BSG ^® and Novamyl ^®, likewise from Novozymes.

Examples of a-amylases from other organisms are further developments of a-amylase sold under the trade names Fungamyl.RTM ^® from Novozymes from Aspergillus niger and A. oryzae. Another commercial product is the Amylase-LT ^® .

The prior art includes the three patent applications WO 96/23873 A1,

WO 00/60060 A2 and WO 01/66712 A2, which have been registered by Novozymes.

WO 96/23873 A1 describes several different point mutations in a total of more than 30 different positions in four different wild-type amylases and claims them for all amylases with at least 80% identity to one of these four; they should have changed enzymatic properties with regard to thermal stability, oxidation stability and calcium dependence. The application WO 00/60060 A2 also names a large number of possible amino acid exchanges in 10 different positions on the a-amylases from two different microorganisms and claims those for all amylases with a homology of at least 96% identity to them. Finally, WO 01/66712 A2 denotes 31 different amino acid positions, some of which are identical with the abovementioned, which have been mutated in one of the two a-amylases mentioned in the application WO 00/60060 A2. For example, WO 96/23873 A1 concretely shows the possibility of replacing an M in position 9 in the a-amylases mentioned according to the AA560 count with an L, in position 202 M for L and that in positions 182 and 183 ( or 183 and 184) lying amino acids. WO 00/60060 A2 specifically discloses the

Amino acid variation N195X (basically against any other amino acid).

The water-soluble material is particularly preferred

Polyvinyl alcohol.

In one embodiment of the invention, the water-soluble material comprises mixtures of different substances. Such mixtures enable the mechanical properties of the container to be adjusted and can influence the degree of water solubility.

The water-soluble material preferably contains at least one polyvinyl alcohol and / or at least one polyvinyl alcohol copolymer. "Polyvinyl alcohol" (abbreviation PVAL or PVA occasionally also PVOH) is the name for polymers of the general structure which in small proportions (approx. 2%) also structural units of the type

- CH ₂ - CH— CH— CH ₂ -

OH OH included.

Commercially available polyvinyl alcohols with white-yellowish powder or granules

Degrees of polymerization in the range of approximately 100 to 2500 (molar masses of approximately 4000 to 100,000 g / mol) are offered, have degrees of hydrolysis of 98 to 99 mol% or 87 to 89 mol%, and therefore still contain a residual content of acetyl groups . The manufacturers characterize the polyvinyl alcohols by stating the degree of polymerization of the

Starting polymers, the degree of hydrolysis, the saponification number or

Solution viscosity.

Depending on the degree of hydrolysis, polyvinyl alcohols are soluble in water and a few strongly polar organic solvents (formamide, dimethylformamide, dimethyl sulfoxide); They are not attacked by (chlorinated) hydrocarbons, esters, fats and oils. Polyvinyl alcohols are classified as toxicologically safe and are at least partially biodegradable. The water solubility can be reduced by post-treatment with aldehydes (acetalization), by complexing with Ni or Cu salts or by treatment with dichromates, boric acid or borax. The polyvinyl alcohol coatings are largely impenetrable for gases such as oxygen, nitrogen, helium, hydrogen, carbon dioxide, however, leave

Pass water vapor through.

In the context of the present invention, it is preferred that the water-soluble material at least partially comprises a polyvinyl alcohol, the degree of hydrolysis of which is 70 to 100 mol%, preferably 80 to 90 mol%, particularly preferably 81 to 89 mol% and in particular 82 to 88 mol -%. In a preferred embodiment, the water-soluble material consists of at least 20% by weight, particularly preferably at least 40% by weight, very particularly preferably at least 60% by weight and in particular at least 80% by weight, of a polyvinyl alcohol, the Degree of hydrolysis is 70 to 100 mol%, preferably 80 to 90 mol%, particularly preferably 81 to 89 mol% and in particular 82 to 88 mol%.

The polyvinyl alcohols described above are widely available commercially, for example under the trademark Mowiol® (Clariant). Polyvinyl alcohols which are particularly suitable in the context of the present invention are, for example, Mowiole 3-83, Mowiol® 4-88, Mowiol® 5-88, Mowiol® 8-88 and L648, L734, Mowiflex LPTC 221 ex KSE and the compounds from Texas Polymers such as for example Vinex 2034.

The water solubility of polyvinyl alcohol polymer can be increased by post-treatment with

Aldehydes (acetalization) or ketones (ketalization) can be changed. Polyvinyl alcohols which have been acetalized or ketalized with the aldehyde or keto groups of saccharides or polysaccharides or mixtures thereof have turned out to be particularly preferred and particularly advantageous because of their extremely good solubility in cold water.

Furthermore, the water solubility can be changed by complexing with Ni or Cu salts or by treatment with dichromates, boric acid, borax and thus adjusted to the desired values. PVAL films are largely impenetrable for gases such as oxygen, nitrogen, helium, hydrogen, carbon dioxide, but allow water vapor to pass through. In addition to polyvinyl alcohol, polymers selected from the group comprising acrylic acid-containing polymers, polyacrylamides, oxazoline polymers, polystyrene sulfonates, polyurethanes, polyesters, polyethers, polylactic acid and / or mixtures of the above polymers can also be added to the film material suitable as water-soluble material.

Suitable water-soluble films for use as the water-soluble material of the water-soluble potion according to the invention are films which are sold under the name Monosol M8630 by MonoSol LLC. Other suitable films include films with the designation Solublon® PT, Solublon® KA, Solublon® KC or Solublon® KL from Aicello Chemical Europe GmbH or the films VF-HP from Kuraray.

Preferred water-soluble materials are characterized in that they

Hydroxypropylmethyl cellulose (HPMC), which have a degree of substitution (average number of methoxy groups per anhydroglucose unit of cellulose) from 1.0 to 2.0, preferably from 1.4 to 1.9, and a molar substitution (average number of

Hydroxypropoxyl groups per anhydroglucose unit of cellulose) from 0.1 to 0.3, preferably from 0.15 to 0.25.

Polyvinylpyrrolidones, abbreviated as PVP, are produced by radical polymerization of 1-vinylpyrrolidone. Commercial PVPs have molecular weights in the range of approx.

2,500 to 750,000 g / mol and are offered as white, hygroscopic powders or as aqueous solutions.

Polyethylene oxides, PEOX for short, are polyalkylene glycols of the general formula

H- [0-CH ₂ -CH ₂ ] n-0H which are produced industrially by base-catalyzed polyaddition of ethylene oxide (oxirane) in mostly small amounts of water-containing systems with ethylene glycol as the starting molecule. They usually have molar masses in the range from approx. 200 to 5,000,000 g / mol, corresponding to degrees of polymerization n from approx. 5 to> 100,000. Polyethylene oxides have an extremely low concentration of reactive hydroxyl end groups and show only weak glycol properties.

Gelatin is a polypeptide (molecular weight: approx. 15,000 to> 250,000 g / mol), which is primarily obtained by hydrolysis of the collagen contained in the skin and bones of animals under acidic or alkaline conditions. The amino acid composition of the gelatin largely corresponds to that of the collagen from which it was obtained and varies in

Dependence on its provenance. The use of gelatin as a water soluble Envelope material is particularly widespread in the pharmaceutical industry in the form of hard or soft gelatin capsules. In the form of films, gelatin is used only to a minor extent because of its high price in comparison to the abovementioned polymers.

In the context of the present invention, preference is given to water-soluble materials which comprise a polymer from the group starch and starch derivatives, cellulose and cellulose derivatives,

in particular include methyl cellulose and mixtures thereof.

Starch is a homoglycan, with the glucose units linked a-glycosidically. Starch is made up of two components of different molecular weights (MW): approx. 20 to 30% straight-chain amylose (MW approx. 50,000 to 150,000) and 70 to 80% branched-chain

Amylopectin (MW approx. 300,000 to 2,000,000). It also contains small amounts of lipids, phosphoric acid and cations. While the amylose forms long, helical, intertwined chains with about 300 to 1,200 glucose molecules as a result of the binding in the 1,4 position, the chain in the amylopectin branches after an average of 25 glucose units through 1,6 binding to form a knot-like structure with about 1,500 to 12,000 molecules of glucose. In addition to pure starch, starch derivatives which can be obtained from polymer-analogous reactions from starch are also suitable for the production of water-soluble containers in the context of the present invention. Such chemically modified starches include, for example, products

Esterifications or etherifications in which hydroxy hydrogen atoms have been substituted. Starches in which the hydroxyl groups have been replaced by functional groups which are not bound via an oxygen atom can also be used as starch derivatives. The group of starch derivatives includes, for example, alkali starches, carboxymethyl starch (CMS), starch esters and starches and amino starches.

Pure cellulose has the formal gross composition (C6H10O5) and, formally speaking, is a ß-1, 4-polyacetal of cellobiose, which in turn is made up of two molecules of glucose. Suitable celluloses consist of approximately 500 to 5,000 glucose units and consequently have average molecular weights of 50,000 to 500,000. Cellulose-based disintegrants which can be used in the context of the present invention are also cellulose derivatives which can be obtained from cellulose by polymer-analogous reactions. Such chemically modified celluloses include, for example, products from esterifications

or etherifications in which hydroxy hydrogen atoms have been substituted. However, celluloses in which the hydroxyl groups have been replaced by functional groups which are not bound via an oxygen atom can also be used as cellulose derivatives. The group of cellulose derivatives includes, for example, alkali celluloses, carboxymethyl cellulose (CMC), cellulose esters and ethers and aminocelluloses. The water-soluble material can have other additives. These are, for example, plasticizers, such as, for example, dipropylene glycol, ethylene glycol or diethylene glycol, water or disintegrating agents.

Polyvinyl alcohol is particularly preferably used as the water-soluble material. On the one hand, this is easy to process and inexpensive to maintain. In addition, it is particularly soluble in water and thus enables the container to be used in a variety of ways.

It is preferred according to the invention if at least one bittering agent is contained in the water-soluble material to increase product safety.

Preferred bittering agents have a bitter value of at least 1,000, preferably at least 10,000, particularly preferably at least 200,000. The standardized procedure described in the European Pharmacopoeia (5th edition Grundwerk, Stuttgart 2005, Volume 1 General Part Monograph Groups, 2.8.15 Bitter Value p. 278) is used to determine the bitter value. An aqueous solution of quinine hydrochloride, whose bitter value is fixed at 200,000, serves as a comparison. This means that 1 gram of quinine hydrochloride makes 200 liters of water bitter. The inter-individual taste differences in the organoleptic examination of bitterness are compensated by a correction factor.

Very particularly preferred bittering agents are selected from denatonium benzoate, glycosides, isoprenoids, alkaloids, amino acids and mixtures thereof, particularly preferred

Denatonium benzoate.

Glycosides are organic compounds of the general structure R-O-Z, in which an alcohol (R-OH) is linked to a sugar part (Z) via a glycosidic bond.

Suitable glycosides are, for example, flavonoids such as quercetin or naringin or

Iridoid glycosides such as aucubin and in particular secoiridoid such as amarogentin, dihydrofoliamentin, gentiopicroside, gentiopikrin, swertiamarin, sweroside, gentioflavoside, centauroside, methiafolin, harpagoside and centapikrin, sailicin or condurangin.

Isoprenoids are compounds that are formally derived from isoprene. Examples are in particular terpenes and terpenoids.

Suitable isoprenoids include, for example, sequiterpene lactones such as absinthin, artabsin, cnicin, lactucin, lactucopikrin or salonitenolide, monoterpene ketones (thujones) such as

for example a-thujone or β-thujone, tetranortriterpenes (limonoids) such as deoxylimones, Desoxylimonic acid, limonin, ichangin, iso-obacunonic acid, obacunon, obacunonic acid, nomilin or nomilic acid, terpenes such as marrubin, premarrubin, carnosol, carnosolic acid or quassin.

Alkaloids refer to naturally occurring, chemically heterogeneous, mostly alkaline, nitrogen-containing organic compounds of secondary metabolism that act on the animal or human organism.

Suitable alkaloids are, for example, quinine hydrochloride, quinine hydrogen sulfate,

Quinine dihydrochloride, quinine sulfate, columbine and caffeine.

Suitable amino acids include, for example, threonine, methionine, phenylalanine, tryptophan, arginine, histidine, valine and aspartic acid.

Particularly preferred bitter substances are quinine sulfate (bitter value = 10,000), naringin (bitter value = 10,000), sucrose octaacetate (bitter value = 100,000), quinine hydrochloride, denatonium benzoate (bitter value> 100,000,000) and mixtures thereof, very particularly preferred

Denatonium benzoate (eg available as Bitrex ^® ).

Based on its total weight, the water-soluble material preferably contains bittering agents (particularly preferably denatonium benzoate) in a total amount of at most 1 part by weight of bitter substance to 250 parts by weight of viscoelastic, solid surfactant composition (1: 250), particularly preferably at most 1: 500, very particularly preferably at most 1: 1000.

It is particularly preferred in the context of the invention to provide a liquid multicomponent detergent in a container made of water-soluble material with at least two separate chambers, comprising as components at least two liquid compositions, a solution of 1 g of the multicomponent detergent in 100 ml of water has a pH value (20 ° C) of> 7, characterized in that it contains in total in relation to the weight of the total detergent:

B e i s p i e l e

The following liquid detergents from Table 1 were prepared by mixing the components. A homogeneous solution of the catechol compound in a mixture of the nonionic surfactant and the non-aqueous, organic solvent was first prepared. Then water and the alkalizing agent and the other constituents of the detergent were added and mixed. The enzymes were then added.

Table 1: Liquid detergent

All formulations V1 to V3 and E1 to E2 were subjected to a washing test to check the cleaning performance. Washing tests were carried out at 40 ° C as a triple determination of soiling on cotton. For this purpose, wash liquors consisting of 70 g of the respective liquid detergent from Table 1 were in each case 17 liters of water at 16 ° dH. scheduled. Already in the visual comparison of the washing results there was no evidence

Difference in result. The same result is obtained when 35 g of the

Composition V1 and 35 g of composition E1 or, instead of composition E1, 35 g of composition E2 in 17 l of water each at 16 ° dH. The pH of these wash liquors was 7.5.

The detergents of the compositions V2 and V3 differ from the composition V1 by the presence of a catechol compound and are therefore more intense, darker in color to an orange tone.

The compositions E1 and E2 differ from the compositions V2 and V3 only in their pH. Compositions E1 and E2 show no discoloration to a darker shade despite the presence of a catechol compound.

As the washing test also shows, all formulations are comparable in their washing performance. The detergents according to the invention thus show good washing performance and have no discoloration towards darker shades.
