EP3020794B1 - Detergent composition and use of the same - Google Patents

Description

The invention relates to a detergent composition, a detergent portion and the use thereof for dyeing and washing textiles.

Detergents for textiles are well known from the prior art. Frequent washing of colored clothes is known to gradually wash out the colors and the laundry loses its color fastness.

There is therefore a need for detergent compositions and processes which are suitable not only to largely prevent loss of color fastness, but in particular to enable freshly washed-out colors to be refreshed.

Reactive dyes are characterized by the fact that they bind to the fiber through covalent bonds. This gives them a high wash fastness. Effective reactive dyes have to meet numerous requirements. For example, the dye molecules have to be water-soluble and absorb in the desired wavelength range. In order to be able to bind to the fiber, the dye molecules have one or more identical or different anchor groups. These anchor groups must be suitable for forming covalent bonds with the fiber, in particular with free hydroxyl groups of cellulose molecules. Effective reactive dyes are therefore necessarily highly reactive towards nucleophiles and mostly suitable "alkylating agents".

However, the high reactivity of the reactive anchor has the disadvantage that the reactive dye molecule can react not only with the textile fiber, ie with the free hydroxy functionalities of cellulose, but also with other nucleophiles. This can result in a significant loss of reactive dye molecules. In aqueous, in particular alkaline solution, water and especially hydroxide anions react with the dye molecules. This requires precise adjustment and control of the pH of the aqueous solution.

Direct dyes are dyes which are characterized by non-covalent, e.g. van-der-Waals or ionic interactions to which fiber is bound. In order to color the fiber, the dye molecules must have a high affinity for the fiber to be colored. The affinity of the direct dyes and thus the quality of the color is usually clearly pH-dependent. This requires precise adjustment and control of the pH of the aqueous solution.

Essential components of detergents are anionic and non-ionic surfactants as well as builders or builder substances and carbonates. The detergent fleet, i.e. the aqueous detergent solution is usually basic.

Suitable detergent enzymes are added to modern detergents, which mostly break down contaminants through hydrolytic cleavage. Amylases, lipases, cellulases and preferably proteases are used in detergents. The pollutants are usually cleaved by reaction with particularly reactive nucleophilic groups in the active center of these enzymes. For example, in the case of the well-studied serine proteases in the active center, there is a basic histidine side group in addition to the nucleophilic hydroxyl group of the reactive serine. This histidine residue has an activating effect on the nucleophiles of the hydroxyl group of the serine residue.

However, the high reactivity of the nucleophilic hydroxyl group not only results in the efficient cleavage of dirt molecules, but also side reactions with any other molecules that may be present. Because of their mostly high nucleophiles, the enzymes used are particularly susceptible to undesirable side reactions with reactive groups, such as are present as anchor groups in reactive dyes. It is also known that reactive reagents covalently bind to the nucleophilic group of the enzyme binding and irreversibly inhibit the enzyme and thus render it unusable.

The simultaneous use of colorants with detergents speaks against the essentially predetermined pH value by the detergent and the associated lack of possibility for pH value control of the dye molecules.

A further argument against simultaneous use of reactive dyes as colorants with detergents is that nucleophiles in the detergent fleet, e.g. Hydroxy or surfactant anions, cleavage and thus rendering the reactive dye unusable, before it can bind to the fiber.

A further argument against a simultaneous use of reactive dyes as colorants with detergents is that alkylating reagents can bind covalently to the nucleophilic groups of the detergent enzymes and thus irreversibly inhibit the enzymes and / or this leads to cleavage and thus rendering the reactive dye unusable before it can bind to the fiber.

Detergent compositions are known from the prior art, which may contain limited dyes. However, these dyes are only used to give the detergent a more visually appealing color, similar to how fragrances can be used to give the detergent composition a more pleasant smell. The detergent compositions known from the prior art, however, are not suitable for allowing already washed-out colors to be refreshed without significantly impairing the washing result.

US 2012/0108488 A1 discloses the combination of a direct dye and a reactive dye as laundry colorants, in particular a combination of 0.0003% by weight direct violet 9 and 0.06% by weight "S-ACMC" as well as a mixture of 0.0001 direct violet 9 (active ) with 0.01% by weight "S-ACMC". These compositions are used in particular to improve cleaning and freshness in low temperature washes.

US 2009/0088362 A1 discloses cleaning compositions, in particular detergents, containing both basic black 1 (through 11) and direct black 1 (through 204) as well as reactive black 1 (through 51) and generally mixtures thereof as dyes. Furthermore, a mixture of direct violet 9 in amounts of 0.0003% by weight and 0.0005% by weight and a conjugate of xyloglucan with CI reactive blue 4 in amounts of 0.09% by weight, 0.2 % And 0.3% by weight are disclosed.

WO 2006/032327 A1 also discloses a detergent composition which is said to be suitable for maintaining the white appearance of polyester-cotton garments. For this purpose, a mixture of a hydrophobic colorant with one selected from a group comprising a hydrolyzed reactive dye, an acid dye and a direct dye is proposed.

EP 0 373 696 A2 relates to a fabric softener that contains specific blends of acid blue 254, reactive red 147 and direct blue 199.

WO 2008/114203 A1 suggests detergent compositions with a reactive dye in an amount of 0.00001% to 0.01% by weight.

It is therefore an object of the present invention to provide a detergent composition and a method which are suitable not only to largely prevent loss of color fastness, but in particular to enable freshly washed-out colors to be refreshed without significantly impairing the washing result, and to reduce washing out of the refreshed paint in subsequent wash cycles. The object of the invention is achieved by a detergent composition comprising at least one first reactive dye in an amount of 0.82 to 2.8% by weight and at least one first direct dye in an amount of 0.66 to 2.64% by weight, in each case based on the total amount of the detergent composition, further comprising at least one surfactant in an amount of 0.3% by weight to 20% by weight and at least one fixer in an amount of 0.1% by weight to 30% by weight , wherein the weight percentages are based in each case on the total amount of the detergent composition.

The reactive dyes are preferably present as vinyl sulfone dyes and more preferably as reactive red, reactive yellow, reactive blue, reactive green or even more preferably as reactive black, preferably reactive black 5, or as combinations thereof. The direct dyes are preferably in the form of acid dyes and more preferably in the form of Direct Blue, Direct Red, Direct Yellow or Direct Black, preferably Direct Black 22, or a combination of these. The fixers are preferably in the form of silicates and more preferably in the form of sodium metasilicate. The builders are preferably in the form of zeolites. The surfactants are preferred as anionic and non-ionic surfactants. The chelating agent is preferably Trilon. The enzymes are preferably in the form of proteases. The soaps are preferably in the form of fatty acid soaps.

To develop the washing performance, the detergent compositions according to the invention can contain surface-active substances from the group of anionic, nonionic, zwitterionic or cationic surfactants. Anionic surfactants and nonionic surfactants are preferred. Anionic surfactants used are, for example, those of the sulfonate and sulfate type.

Preferred surfactants of the sulfonate type are C9-13 alkylbenzenesulfonates, olefin sulfonates, i.e. Mixtures of alkene and hydroxyalkanesulfonates and disulfonates, as can be obtained, for example, from C12-18 monoolefins with a terminal or internal double bond by sulfonation with gaseous sulfur trioxide and subsequent alkaline or acidic hydrolysis of the sulfonation products. Also suitable are alkanesulfonates obtained from C12-18 alkanes, for example by sulfochlorination or sulfoxidation with subsequent hydrolysis or neutralization. Likewise, the esters of 2-sulfo fatty acids (ester sulfonates), e.g. B. the 2-sulfonated methyl ester of hydrogenated coconut, palm kernel or tallow fatty acids.

Other suitable anionic surfactants are sulfonated fatty acid glycerol esters. Fatty acid glycerol esters are to be understood as meaning mono-, di- and triesters and their mixtures, such as are obtained in the production by esterification of a monoglycerol with 1 to 3 mol of fatty acid or in the transesterification of triglycerides with 0.3 to 2 mol of glycerol. Preferred sulfated fatty acid glycerol esters are the sulfate 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.

Other suitable anionic surfactants are alk (en) yl sulfates. As alk (en) yl sulfates, the alkali and especially the sodium salts of the sulfuric acid half esters of C12-C18 fatty alcohols, for example from coconut oil alcohol, tallow fatty alcohol, lauryl, myristyl, cetyl or Stearyl alcohol or the C10-C20 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, petrochemical-based straight-chain alkyl radical which have a degradation behavior similar to that of the adequate compounds based on oleochemical raw materials. The C12-C16-alkyl sulfates and C12-C15-alkyl sulfates and C14-C15-alkyl sulfates are preferred from the point of view of washing technology. The sulfuric acid monoesters of the straight-chain or branched C7-21 alcohols ethoxylated with 1 to 6 moles of ethylene oxide, such as 2-methyl-branched C9-11 alcohols with an average of 3.5 moles of ethylene oxide (EO) or C12-18 fatty alcohols with 1 up to 4 moles of EO are suitable.

Other suitable anionic surfactants are also the salts of alkylsulfosuccinic acid, which are also referred to as sulfosuccinates or as sulfosuccinic acid esters, and monoesters and / or diesters of sulfosuccinic acid with alcohols, preferably fatty alcohols and especially ethoxylated fatty alcohols. Preferred sulfosuccinates contain C8-18 fatty alcohol residues or mixtures thereof. Particularly preferred sulfosuccinates contain a fatty alcohol residue which is derived from ethoxylated fatty alcohols, which in themselves are nonionic surfactants (description see below). Again, sulfosuccinates, the fatty alcohol residues of which are derived from ethoxylated fatty alcohols with a narrow homolog distribution, are particularly preferred. It is also possible to use alk (en) ylsuccinic acid with preferably 8 to 18 carbon atoms in the alk (en) yl chain or salts thereof.

Soaps are particularly suitable as further anionic surfactants. Saturated fatty acid soaps, 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, eg. B. 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 Triethanolamine. The anionic surfactants are preferably in the form of their sodium or potassium salts, in particular in the form of the sodium salts. In a further embodiment of the invention, surfactants are used in the form of their magnesium salts.

The nonionic surfactants used are preferably alkoxylated, advantageously ethoxylated, in particular primary alcohols having preferably 8 to 18 carbon atoms and an average of 1 to 12 moles of ethylene oxide (EO) per mole of alcohol, in which the alcohol radical can be linear or preferably methyl-branched in the 2-position or may contain linear and methyl-branched radicals in the mixture, as are usually present in oxo alcohol radicals. In particular, however, alcohol ethoxylates with linear residues from alcohols of native origin with 12 to 18 carbon atoms, for. B. from coconut, palm, tallow or oleyl alcohol, and an average of 2 to 8 moles of EO per mole of alcohol preferred. The preferred ethoxylated alcohols include, for example, C12-14 alcohols with 3 mol EO or 4 mol EO, C9-11 alcohol with 7 mol EO, C13-15 alcohols with 3 mol EO, 5 mol EO, 7 mol EO or 8 Mol EO, C12-18 alcohols with 3 mol EO, 5 mol EO or 7 mol EO and mixtures thereof, and mixtures of C12-14 alcohol with 3 mol EO and C12-18 alcohol with 5 mol EO. The degrees of ethoxylation given represent statistical averages, which can be an integer or a fraction for a specific product. Preferred alcohol ethoxylates have a narrow homolog distribution (narrow range ethoxylates, NRE). In addition to these nonionic surfactants, fatty alcohols with more than 12 mol EO can also be used. Examples of this are tallow fatty alcohol with 14 mol EO, 25 mol EO, 30 mol EO or 40 mol EO.

Another class of preferably used nonionic surfactants, which are used either as the sole nonionic surfactant or in combination with other nonionic surfactants, are alkoxylated, preferably ethoxylated or ethoxylated and propoxylated fatty acid alkyl esters, preferably with 1 to 4 carbon atoms in the alkyl chain, in particular fatty acid methyl ester A class of nonionic surfactants that can be used advantageously are the alkyl polyglycosides (APG). Usable alkyl polyglycosides satisfy the general formula RO (G) Z, in which R represents a linear or branched, in particular in the 2-position methyl-branched, saturated or unsaturated, aliphatic radical having 8 to 22, preferably 12 to 18 C atoms and G is the symbol which stands for a glycose unit with 5 or 6 C 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.

In particular, zeolites, silicates, carbonates, organic cobuilders and - where there are no ecological objections to their use - phosphates are provided as builders or other additives. Suitable crystalline, layered sodium silicates have the general formula NaMSi _x O _2x-1 • 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 beta and delta sodium disilicate Na ₂ Si ₂ O ₅ • y H 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 are delayed in dissolving and have secondary washing properties. The delay in dissolution compared to conventional amorphous sodium silicates can have been caused in various ways, for example by surface treatment, compounding, compaction / compression or by overdrying. In the context of this invention, the term “amorphous” is also understood to mean “X-ray amorphous”. This means that the silicates in X-ray diffraction experiments do not provide sharp X-ray reflections, as are typical for crystalline substances, but at most one or more maxima of the scattered X-rays, which have a width of several degree units of the diffraction angle. It can lead to particularly good builder properties if the silicate particles provide washed-out or even sharp diffraction maxima in electron diffraction experiments. This is to be interpreted as meaning that the products have microcrystalline regions with a size of approximately 10 to approximately a few hundred nm, values of up to max. about 50 nm and in particular up to max. about 20 nm are preferred. Compressed / compacted are particularly preferred amorphous silicates, compounded amorphous silicates and over-dried X-ray amorphous silicates.

An optionally used finely crystalline, synthetic and bound water-containing zeolite is preferably zeolite A and / or P. As the zeolite of the P type, zeolite MAP (eg commercial product: Doucil A24 from Crosfield) is particularly preferred. However, zeolite X and mixtures of zeolites 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 (approx. 80% by weight Zeolite X), which are described by the formula nNa ₂ O • (1-n) K ₂ O • Al ₂ O ₃ • (2-2.5) SiO ₂ • (3.5-5.5) H ₂ O. can. Suitable zeolites have an average particle size of less than about 10 μm (volume distribution; measurement method: Coulter Counter) and preferably contain about 18 to about 22% by weight, in particular about 20 to about 22% by weight, of bound water.

The use of generally known phosphates as builder substances is also possible in detergents, provided that such use should not be avoided for ecological reasons. The sodium salts of orthophosphates, pyrophosphates and in particular tripolyphosphates are particularly suitable.

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, nitrilotriacetic acid (NTA), as long as their 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 are therefore also used for Setting a lower and milder pH of detergent and cleaning agent portions according to the invention. In this context, citric acid, succinic acid, glutaric acid, adipic acid, gluconic acid and any mixtures of these should be mentioned in particular.

Polymeric polycarboxylates are further preferred 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 about 500 to about 70,000 g / mol. The molecular weights given for polymeric polycarboxylates in the context of the present invention are weight-average molecular weights MW of the respective acid form, which were basically determined by means of gel permeation chromatography (GPC), using a UV detector. The measurement was made against an external polyacrylic acid standard, which provides realistic molecular weight values due to its structural relationship to 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 acids are generally significantly higher than the molecular weights specified in the context of the present invention. Suitable polymers are, in particular, polyacrylates, which preferably have a molecular weight of about 2,000 to about 20,000 g / mol. Because of their superior solubility, the short-chain polyacrylates which have molar masses of about 2,000 to about 10,000 g / mol, particularly preferably from about 3,000 to about 5,000 g / mol, can in turn be preferred from this group.

Also suitable are copolymeric polycarboxylates, in particular those of acrylic acid with methacrylic acid or 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 molar mass, based on free acids, is generally 2,000 to 70,000 g / mol, preferably 20,000 to 50,000 g / mol and in particular about 30,000 to about 40,000 g / mol. The (co) polymers Polycarboxylates can be used either as a powder or as an aqueous solution.

To improve water solubility, the polymers can also contain allylsulfonic acids, such as allyloxybenzenesulfonic acid and methallylsulfonic acid, as the monomer. In particular, biodegradable polymers from more than two different monomer units are preferred.

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.

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 their mixtures and from polyol carboxylic acids such as gluconic acid and / or glucoheptonic acid.

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 processes, for example acid-catalyzed or enzyme-catalyzed. They are preferably hydrolysis products with average molecular weights in the range from about 400 to about 500,000 g / mol. A polysaccharide with a dextrose equivalent (DE) in the range from about 0.5 to about 40, in particular from about 2 to about 30, is preferred, DE being a customary measure of the reducing action of a polysaccharide compared to dextrose, which has a DE of 100. Both maltodextrins with a DE between 3 and 20 and dry glucose syrups with a DE between about 20 and about 37 and so-called yellow dextrins and white dextrins with higher molar masses in the range from about 2,000 to about 30,000 g / mol can be used.

Oxydisuccinates and other derivatives of disuccinates, preferably ethylenediamine disuccinate, are further suitable co-builders.

Further useful organic co-builders are, for example, acetylated hydroxycarboxylic acids or their salts, which may 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. Another class of substances with co-builder properties are phosphonates.

In addition, all compounds that are able to form complexes with alkaline earth metal ions can be used as co-builders.

Fragrances are used in the detergent composition according to the invention in order to improve the overall olfactory impression of the products.

Individual perfume compounds can be used as perfume oils or fragrances, for example the synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type.

Fragrance compounds of the ester type are, for example, benzyl acetate, phenoxyethyl isobutyrate, p-t-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinyl acetate, phenylethyl acetate, linalyl benzoate, benzyl formate, ethyl methylphenylglycinate, allylcyclohexyl benzylatepylpropylate, stally. The ethers include, for example, benzyl ethyl ether.

The aldehydes include e.g. B. linear alkanals with 8 to 18 carbon atoms, citral, citronellal, citronellyloxyacetaldehyde, cyclamenaldehyde, hydroxycitronellal, lileal and bourgeonal. The ketones include ionones, alpha-isomethyl ionone, and methyl cedryl ketone. To the Al alcohols include anethole, citronellol, eugenol, geraniol, linalool, phenylethyl alcohol and terpineol.

The hydrocarbons mainly include terpenes such as limonene and pinene. Mixtures of different fragrances are preferably used which are coordinated with one another in such a way that they together produce an appealing fragrance. Perfume oils of this type can also contain natural fragrance mixtures as are obtainable from plant sources. Examples are pine, citrus, jasmine, patchouli, rose or ylang-ylang oil. Also suitable are nutmeg oil, sage oil, chamomile oil, clove oil, lemon balm oil, mint oil, cinnamon leaf oil, linden blossom oil, juniper berry oil, vetiver oil, olibanum oil, galbanum oil and labdanum oil as well as orange blossom oil, neroliol, orange peel oil and sandalwood oil.

The fragrances can be incorporated directly into the wash-active preparations; However, it can also be advantageous to apply the fragrances to carriers which increase the adhesion of the perfume to the laundry and ensure a long-lasting fragrance for the textiles due to a slower fragrance release. Cyclodextrins, for example, have proven themselves as such carrier materials. The cyclodextrin-perfume complexes can also be coated with other auxiliaries.

To combat microorganisms, the detergent composition according to the invention can contain antimicrobial agents. Depending on the antimicrobial spectrum and mechanism of action, a distinction is made between bacteriostatics and bactericides, fungistatics and fungicides, etc. Important substances from these groups are, for example, benzalkonium chlorides, alkylarylsulfonates, halophenols and phenol mercuric acetate.

The reactive dyes preferably have an alkylating group. More preferably, the reactive dyes have a triazine and / or vinyl sulfone group as an anchor group, with a vinyl sulfone group being particularly preferred.

Dyes from the group of azo dyes and anthraquinone dyes are preferred as direct dyes. Preferred direct dyes are anionic (acid dyes). Anionic azo and anthraquinone sulfonates are further preferred. Anionic dyes ("acid dyes") in the sense of the present invention are organic salts, the anion of which absorbs light. Substantial dyes are preferred as direct dyes. Your liability is almost exclusively due to Van der Waals forces. Azo and anthraquinone direct dyes are further preferred. The direct dye molecules preferably have a conjugation system with at least 8 double bonds. These are preferably hydrophobic on one side and have a flat construction. Direct Black 22 is particularly preferred as a direct dye.

Black dyes are preferably used, but reactive dyes and / or direct dyes of a different color can also be used, for example also to obtain a dark blue color refreshment. But also yellow, green, red, blue and / or other dyes, such as reactive red, reactive yellow, reactive blue, reactive green and their combinations are conceivable. The desired colors can also be achieved by a combination of different dyes.

Another aspect of the invention relates to detergent portions, the detergent composition according to the invention being formulated in measured portions.

The detergent composition is preferably in particulate form, more preferably in the form of powder, granules or pearls.

In view of the desire of the consumer to obtain detergents, dishwashing detergents or cleaning agents which can be metered more easily and conveniently, these have increasingly been provided in a form which makes dispensing dependent on individual cases superfluous. The detergent portions are preferably in the form of shaped articles, and these are more preferably shaped as tablets (“tabs”), cuboids, briquettes, etc., which are dosed as a whole into the liquor.

In a further variant, the detergent portions are in the form of liquid products, and these are more preferably with water-soluble coatings which dissolve on contact with the aqueous liquor and release the contents into the liquor.

In the following compositions each component of the mixture, e.g. the reactive dye, consist of a compound or a mixture of compounds. For example, So two reactive dyes can be used, which are present together in one brand in the specified areas.

Sodium metasilicate was used in an amount of 5% by weight, zeolites in an amount of 2% by weight, anionic and non-ionic surfactants in an amount of 2% by weight, soaps in an amount of 0.5% by weight. %, Enzymes in an amount of 0.1% by weight, Trilon in an amount of 1% by weight, and sodium carbonate in an amount of 3.4% by weight. Sodium chloride was used in an amount of 82.2% by weight and sodium sulfate in an amount of 2% by weight.

1A and B show photographic results of the comparative experiments described.

In a first test series, 1500 g of white "simple" cotton and in a second test series, 1500 g of white mercerized cotton were dyed in the washing machine at 40 ° C.

Three compositions were examined in each series of experiments. All compositions contained 450 g sodium chloride (about 80% by weight), 50 g metasilicate (about 9% by weight) and 56 g "Ariel® Color" (about 10% by weight). "Ariel® Color" is a detergent composition known to those skilled in the art. Composition 1 also contained 5 g (about 1% by weight) of Remazol Jet Black N 150 (Reactive Black 5). Composition 2 contained 4 g (about 1% by weight) Sirius Schwarz VSF / hc (Direct Black 22). Composition 3 contained both 5 g of Remazol jet black N 150 (about 1% by weight) and 4 g of Sirius Schwarz VSF / hc (about 1% by weight).

Fig. 1A shows the result of washing a "simple" cotton bed sheet. Figure 1B shows the result of washing mercerized cotton (tablecloth fabric). It can be seen that composition 3 gives the best staining result in both test series. Color fastness and opacity of composition 3 are improved, not only compared to the result according to compositions 1 and 2, but also compared to their (imaginary) overlay.
