Abstract

The invention relates to agents and to a method for treating textiles of an essentially uniform, non-white colour. A dye or dye mixture, for example a batik dye and/or a dye salt in the colour of the textiles being washed is advantageously added to a detergent composition such as a colour detergent, wool detergent or delicates detergent and/or a fabric conditioner, said detergent composition being in the form of a powder and/or granules, a tablet and or an aqueous or essentially water-free liquid composition. This prevents the textiles from losing their colour. The invention also relates to a method for producing the inventive agents, to a method for treating washing of an essentially uniform non-white colour with said dye-containing colour detergents and to the use of the inventive agents for obtaining, restoring or intensifying the colour of textiles of an essentially uniform, non-white colour.

Description

"Means and Methods for Treating Textiles of an Essentially Uniform Non-White Color"

The invention relates to an agent for treating textiles of a substantially uniform, non-white color, a detergent composition, such as a color detergent, a wool detergent, a mild detergent and / or a fabric softener, in the form of a powder and / or granules, a tablet and / or an aqueous or a substantially water-free liquid composition is present, a dye or dye mixture, such as batik paint and / or coloring salt, is advantageously added in the color of the textiles to be washed in order to avoid loss of color of the textiles. Furthermore, the invention relates to a process for the production of these agents, a process for treating laundry of a substantially uniform non-white color with said dye-containing colored detergents and the use of these agents for maintaining, refreshing or strengthening the color of essentially uniformly non-white-dyed textiles .

Colored detergents are generally used to wash colored textiles. Colored detergents are understood here to mean those detergents which, unlike heavy-duty detergents, do not contain any substances such as are used in connection with the bleaching of laundry. Such substances are, in particular, oxygen-releasing bleaches such as sodium perborate or sodium carbonate, bleach activators such as tetraacetylethylene diamine (TAED) and bleach stabilizers such as magnesium silicate. Such fabrics would usually cause the colors to fade if they were washed several times.

However, even when washing several times with color detergents that do not contain bleach, bleach activators or bleach stabilizers, the colors usually fade, especially with heavily dyed textiles, especially dark textiles such as those with black, dark blue or dark green color. Especially on textiles of these colors, the normal treatment with color detergents often gives the consumer an undesirable white shimmer. The reasons for this are mostly the mechanical stress on the textiles during the washing process and the interactions of the dyes of the textiles with surfactants, complexing agents and enzymes. In addition, strong exposure to light, especially ultraviolet sunshine, causes a loss of color depth, especially in the case of color-intensive colors such as black.

British patent application GB-A-2 199 338 describes a process for producing colored detergent particles, the detergent powder being mixed with a dye and the powder being treated with a binder. However, this is only intended to give the detergent, which often appears slightly brownish when admixed with enzymes or bleach precursors, a more attractive color. Agents according to the invention contain 71.4% by weight of base powder, 0.6% by weight of dye, 25% by weight of bleaching system and other ingredients. The base powder consists of 9 to 10% by weight of alkylbenzenesulfonate, 2 to 3% by weight of nonionic surfactant, furthermore sodium aluminosilicate or tripolyphosphate, sodium silicate, sodium sulfate and other constituents, the amounts given being based on the base powder.

The colored agents described in German patent application DE-A-195 42 830, which can be used as constituents of universal detergents or as universal detergents, are initially intensely colored, but are only intended to appeal to the aesthetic perception of the consumer. The colorants are partially or completely oxidatively destroyed in the washing process and do not stain the textiles even after multiple washes. In addition, the aforementioned application discloses, as known prior art, detergents with dyes in the form of speckles in the preferred colors green and blue, which on the one hand are intended to compensate for the yellowing of washed fabric and on the other hand are intended to make the detergent more appealing to the consumer.

Such a granular blue composition, which, however, is not intended to deepen an existing blue color, but is intended to counteract the yellowing of textiles, is known from US Pat. No. 3,529,923. The granular blue composition essentially consists of a water-soluble inorganic, alkaline, hydratable salt, 0.1 to 15% by weight of ultramarine blue and 0.004 to 5% by weight of a substance selected from certain quaternary ammonium compounds and reduces the tendency of the ultramarine to stain . As an exemplary embodiment, this composition is contained in an amount of 2.5% by weight in a granular detergent composition which contains 14% by weight alkylbenzenesulfonates, 42% by weight sodium tripolyphosphate, 14 wt .-% sodium sulfate, 6 wt .-% sodium silicate, 1.5 wt .-% sodium toluenesulfate and other ingredients, including water.

Another composition with a slight blueing effect that improves the apparent whiteness of the textile is known, for example, from US Pat. No. 3,958,928. Here, too, however, no coloring of the textile is to be brought about, but only counteract yellowing by means of the complementary color blue.

Colored detergent compositions which give the products an attractive color without the effect of color on the textiles are disclosed in US Pat. No. 5,770,552. The US patent describes a method for incorporating coloring compositions into soap and detergent and cleaning agent bars.

Japanese patent application JP-A-49/033 905 describes water-soluble encapsulated, water-soluble dyes which can be salted out and added to detergents for optical purposes.

Japanese patent application JP-A-03/146 600 describes a particulate detergent composition which, in addition to a commercially available detergent, contains particles of a compound which are enclosed in a microemulsion-based gel matrix. 0.5 to 80% by weight of such particles, which can consist of dye, glazing agent, perfume, gloss agent, etc., 0.5 to 15% by weight of surface-active substance, 0.5 to 20% by weight of gelling agent, 10 up to 90% by weight of water and 0 to 80% by weight of oil in an oil-water ratio between 1: 4 and 4: 1 are contained in the composition. The surface-active substance ensures a stable microemulsion. The gelling agent is used to produce a non-liquid gel, which is then mixed with the washing powder. For example, enclosed paint prevents textiles from bleeding out during washing and ensures that washed textiles appear to be acceptable.

German patent application DE-A-39 03 926 relates to dyeing aids and a process for single-bath, one-step dyeing of textile fiber materials. The tools include anionic and nonionic surfactants, with 1 to 60 wt .-% of active substance are the surfactants from the group formed by C ₈ -C ₂₄ -alk (en) yl sulfates and / or _I4 C _-C18 alkane and / or C ₁₀ -C ₁₄ alkylbenzenesulfonates and / or from the group formed by ethoxylated castor oil and / or alkoxylated C ₈ -C ₂₄ alk (en) yl alcohols and / or C ₈ -C ₁₂ alkylphenols. 1 to 25% by weight of the active substance are sulfated hydroxyalkyl alkyl polyalkenyl glycol ethers, 1 to 30% by weight of the active substance C ₂ -C ₁₂ alkyl alcohols are punched. These dyeing aids are intended to produce uniform and vivid colorations on the textile material without the fastness to use such as light, rubbing and wet fastness being adversely affected. However, detergents for household use are not targeted here.

Finally, European patent application EP-A-0 220 016 discloses the use of cellulase as a way of preserving the color of textiles, as a result of which fine, undyed cellulose fibers, which come to the surface of the textile during washing, are broken down from the lower fabric, which otherwise reduce the color impression of the textile would. Here, however, there is the undesirable effect that the textile material is attacked by the cellulose in order to recolor the textiles. Further applications for the color refreshment of textiles by cellulase are the European patent applications EP-A-0 495 258, EP-A-0 552 276 and EP-A-0 586 375 and the application WO-A-95/27036. These recent applications show that refreshing the dyeing of textiles is still a problem today.

An object of the invention was therefore to provide a colored detergent for textiles of a substantially uniform non-white color which counteracts the loss of color of textiles during washing and which maintains, refreshes or enhances the color of the textiles.

Another object of the invention was to develop a method for treating textiles with the aid of this agent.

It has now been found that the addition of a colorant such as batik paint and / or coloring salt in a color matching the color of the textiles to a powdery, granular, tablet-shaped or liquid colored detergent or a fabric softener, wool or mild detergent largely prevents this loss of color and a restoration or intensification of the color effect of the textiles.

In a first embodiment, the invention therefore relates to an agent for treating textiles of a substantially uniform, non-white color, comprising a detergent composition and at least one colorant composition, the volume-based ratio of colorant composition to detergent composition being at least 0.05: 1. The colorant composition, which advantageously corresponds to the color of the textiles, largely prevents a loss of color of textiles or can intensify the color effect of already faded textiles.

The colorant composition contains dyes and / or pigments that are capable of being absorbed onto textiles. Natural and / or synthetic dyes can be used. The natural dyes include, for example, anthocyanins, alizarin, betalaine, blue wood, chlorophyll, chochenille, curcuma, hemoglobin, indigo, kernels, madder, litmus, orlean, orseille, antique purple, safflower, etc. Synthetic dyes are, for example, aniline blue, aniline black, Anthracite blue, bismarck brown. Chrysonidine, Ciba Blue, Fuchsine, Hydron Blue, Immedial Black, Congo Red, Crystal Violet, Malachite Green, Methylene Blue, Methyl Orange, Methyl Violet, Variamine Blue, Victoria Blue. The dyes mostly contain chromophoric groups such as azo, azine, anthraquinone, acridine, cyanine, oxazine, polymethine, thiazine, triarylmethane groups, etc. The dyes are often based on their behavior to the fiber or divided into the dyeing technique to be used. The most important representatives are basic or cationic dyes, pickling, direct, dispersion, development, vat, metal complex, reactive, acid, sulfur dyes and noun dyes. Furthermore, dyes which correspond to commercial dye names, for example Sirius, Anthrasol, Erio, Indanthrene, Remazol, Basilen, Levafix, Cibacron, Drimaren, Procion dyes, etc., can also be used as dyes .

In general, aromatic or heterocyclic and either ionic or nonionic compounds (for example disperse dyes) can be used as synthetic dyes. In the former, a distinction is made between anionic and cationic dyes, the anionic dyes having a negatively charged dye ion and the cationic dyes having a positively charged dye ion. The anionic dyes are preferably used as metal salts, the nature of the cations having no effect on the color; it is mainly the sodium salts of sulfonic acids, amino or imino acids or fluorescein. Amino acids are mainly used as cationic dyes.

Pigments are practically insoluble, inorganic or organic colorants in the application medium. A distinction is made between natural and synthetic pigments. Inorganic pigments occurring in nature are obtained by mechanical treatment such as grinding, slurrying, drying, etc. Examples include chalk, ocher, umber, green earth, burned terra di Siena, graphite, etc. Synthetic inorganic pigments, especially white. Black, colored and glossy pigments are obtained from inorganic raw materials by chemical and / or physical conversion such as digestion, precipitation, annealing, etc. Examples of this are white pigments such as titanium white (titanium dioxide), lead white, zinc white, lithopone, antimony white, black pigments such as carbon black, iron oxide black , Manganese black as well as cobalt black and antimony black. Colored pigments are, for example, lead chromate, red lead. Zinc yellow, zinc green, cadmium red, cobalt blue, Berlin blue, ultramarine, manganese violet, cadmium yellow, Schweinfurt green, molybdenum orange and red, chrome orange and red, iron oxide red. Chromium oxide green, strontium yellow and many others. Any toxic pigments are preferably excluded from use in the agents according to the invention. Of minor importance for the agents according to the invention are luster pigments with metallic effect pigment and pearlescent pigments, vapor deposition layers, luminescent pigments with fluorescence and. Phosphorescent pigments as well as fillers or extenders.

In general, the inorganic pigments can be divided into the following groups: metal oxides, hydroxides and oxide hydrates, mixed phase pigments, sulfur-containing silicates, metal sulfides and selenides, complex metal cyanides, metal sulfates, chromates and molybdates, inorganic-organic mixed pigments and the metals themselves (bronze pigments ). Due to their chemical stability, inorganic pigments show excellent light, weather and temperature resistance.

Organic pigments found in nature include sepia, rubber belt, bone charcoal, Kasseler brown, indigo, chlorophyll and other plant pigments.

Synthetic organic pigments are, for example, azo pigments, indigoids, dioxazine, quinacridone, phthalocyanine, isoindolinone, perylene and perinone, metal complex. Alkali blue and more recently the diketopyrolopyrrole (DDP) pigments, which have extreme light and weather fastness and provide clear, pure orange to red tones.

In a preferred embodiment, the agents contain batik dyes and / or dye salts as dye compositions.

The batik color counteracts any loss of color in the textiles. Losses of dyes or pigments caused during the washing process are compensated for by the batik color. If the textiles are already faded, the batik color can also intensify the color during the washing process. The chemical constituents of the batik paint do not impair the wash-active substances of commercial detergent compositions, so that their cleaning power is essentially retained. For example, natural dyes are used as batik dyes, but preferably also coupling dyes, direct dyes without or preferably with metal salt aftertreatment, sulfur dyes, vat dyes, preferably cold-dyeing. Naphthol products and / or other dyes such. B. metal complex dyes, reactive dyes, acid dyes, basic or cationic dyes, and / or natural or synthetic, inorganic or organic pigments and solutions of these dyes and / or dispersions or hydrotropic solutions of these pigments in inorganic and / or organic solvents or solvent mixtures, preferably aqueous Solutions. The batik paint can, however, also be present as a mixture of particulate pure dyes and / or pure pigments or as a mixture thereof with other particles.

Coloring salts can contain dye salts and / or fixing salts. The dye salts used are, for example, natural dye substances and / or synthetic dye substances which consist of one or more, preferably water-soluble, ionic dye compounds, which may be anionic and / or cationic dyes, or of ionic or nonionic, here preferably aromatic or there are heterocyclic dyes which are preferably water-soluble and which can be present in a mixture or in a matrix with a fixing salt. Natural dyes that are capable of salt formation or that can be incorporated into a mixture with a fixing salt can also be used as dye salts. Dye salts composed of natural and / or synthetic, inorganic and / or organic pigments can also be used as coloring salts, which are preferably dispersible in an aqueous medium or soluble in the presence of hydrotropes and which can be present in a mixture or in a matrix with a fixing salt.

Fixing salts can be understood to mean dye and pigment-free salts or salt mixtures which promote the absorption of the dyes and / or pigments on the textiles. These are preferably inorganic salts such as sodium chloride, sodium carbonate or sodium sulfate and mixtures thereof.

Dyes and pigments which are present in non-liquid microemulsion-based gels are preferably excluded from use in the agents according to the invention.

Colored detergents, wool detergents, mild detergents and / or fabric softeners which are in the form of a powder and / or granules, a tablet and / or an aqueous or essentially water-free liquid composition can be used as the detergent composition. The solid detergent compositions such as color detergent, wool detergent, mild detergent and / or fabric softener can be in the form of powders, granules and / or tablets. Preferred solid detergent compositions contain surfactants, these comprising anionic surfactants, nonionic surfactants, cationic surfactants and / or amphoteric surfactants, builders, optionally soap, cobuilders, soil repellents and other ingredients typical of solid detergents, such as foam inhibitors, phosphonates, enzymes and graying inhibitors, as well as perfumes and dyes. Preferred amounts of surfactant are 0.1 to 60% by weight, preferably 5 to 50% by weight, in particular 10 to 35% by weight. Advantageous amounts of builder and / or cobuilder are 1 to 90% by weight, preferably 5 to 80% by weight, in particular 10 to 70% by weight.

The solid agents can be at least partially spray dried, granulated and / or extruded. The bulk weights of spray-dried detergent compositions can preferably be between 150 and 1,000 g / lb, particularly between 300 and 800 g / lb. The bulk weights of the granules or extrudates can preferably be between 300 and 1,500 g / lb, particularly between 500 and 1,200 g / lb. The solid agents can also be compressed using a tableting process. The colorant composition can, at least in part, be mixed in before, during or after the spray drying, granulation, extrusion and / or tableting which may be carried out.

Preferred liquid detergents are either water-based or essentially anhydrous, the latter being able to contain up to 5% by weight of water, based on the detergent composition. Preferred liquid aqueous detergent compositions such as color detergent, fabric softener, wool and / or mild detergent contain surfactants, these comprising anionic surfactants, nonionic surfactants, cationic surfactants and / or amphoteric surfactants, optionally soap, builders, cobuilders, soil repellents and other ingredients typical of liquid detergents, such as foam inhibitors, Phosphonates, enzymes and graying inhibitors as well as perfumes and dyes. Agents which do not contain bleaching agents, bleach activators or bleach stabilizers are preferred for the embodiments according to the invention. Typical amounts of surfactant, soap not being included in the liquid aqueous detergents, are 0.1 to 60% by weight, preferably 5 to 50% by weight, in particular 10 to 35% by weight.

Substantially non-aqueous liquid detergents, such as color detergents, wool and / or mild detergents, generally contain relatively large amounts of solvents, preferably organic solvents, and, if appropriate, structurants and / or structure activators. Organically modified phyllosilicates are preferred as structuring agents used. Higher amounts of liquid nonionic surfactants are preferably used here, so that the amounts of surfactant can be 1 to 90% by weight, preferably 5 to 80% by weight, in particular 10 to 70% by weight.

Even if optical brighteners, bleaches, bleach activators and / or bleach stabilizers may be present in the detergent composition, these undesirably reduce the dyeing effect according to the invention. Detergent compositions preferred according to the invention therefore contain no optical brighteners, bleaches, bleach activators or bleach stabilizers.

The colorant composition can, at least in part, be admixed with the liquid detergent compositions.

It is advisable to use the ratio of colorant composition to detergent composition as a volume ratio, i.e. H. as the ratio of the volumes present when these components are mixed. Especially when dyeing textiles, information on the volume of detergent composition and colorant composition serves on the one hand for easier handling and dosage of these agents. On the other hand, weight information is generally not preferred, especially during the dyeing process, since the amount of detergent composition and colorant composition to be used does not relate to the weight of the textiles, but rather to the area to be inked.

The volume ratio of colorant composition to detergent composition, i. i.e., is at least 0.05: 1, preferably at least 0.08: 1. Preferred compositions contain batik paint and / or dye salt, in particular in a mixture with fixing salt, as the colorant composition.

The preferred, by volume ratio of batik paint and / or dye salt to detergent composition is 0.05: 1 to 0.2: 1, in particular 0.08: 1 to 0.15: 1, a ratio of 0 is particularly preferred. 08: 1 to 0.12: 1.

The preferred, volume-based ratio of fixing salt to detergent composition is 0.5: 1 to 1.5: 1, in particular 0.8: 1 to 1.2: 1. These volume ratios have been found to be particularly favorable in commercial detergent compositions for achieving the effect according to the invention. Typical examples of the ingredients of the detergent compositions are presented below.

The detergent compositions can contain anionic, cationic, nonionic and / or amphoteric or zwitterionic surfactants as surfactants.

Typical examples of anionic surfactants are alkylbenzene sulfonates, alkane sulfonates, olefin sulfonates, alkyl ether sulfonates, glycerol ether sulfonates, α-methyl ester sulfonates, sulfo fatty acids, fatty alcohol ether sulfates, glycerol ether sulfates, hydroxymixed ether sulfates, monoglycerate sulfate, sulfate amate sulfate (sulfate amide) sulfate (sulfate amate) sulfate (sulfate amate) sulfate (sulfate amate) sulfate (sulfate amate) sulfate (sulfate amate) sulfate, sulfate (sulfate) sulfate, and dialkyl sulfosuccinamates, sulfotriglycerides, amide soaps, ether carboxylic acids and their salts, fatty acid isethionates, fatty acid sarcosinates, fatty acid taurides, acyl lactylates, acyl glutamates, acyl tartrates, alkyl oligoglucoside sulfates and alkyl (ether) phosphates. If the anionic surfactants contain polyglycol ether chains, they can have a conventional, but preferably a narrow, homolog distribution.

Preferred surfactants of the sulfonate type are C ₉ -C ₁₃ alkylbenzenesulfonates, olefin sulfonates, ie mixtures of alkene and hydroxyalkanesulfonates, and also disulfonates such as are obtained, for example, from C ₁₂ -C ₁₈ monoolefins with a terminal or internal double bond by sulfonating with gaseous Sulfur trioxide and subsequent alkaline or acidic hydrolysis of the sulfonation products is considered. Also suitable are alkanesulfonates obtained from C _{) 2} -C ₁₈ alkanes, for example by sulfochlorination or sulfoxidation with subsequent hydrolysis or neutralization. Also suitable are the esters of α-sulfo fatty acids (ester sulfonates), e.g. B. the α-sulfonated methyl esters of hydrogenated coconut, palm kernel or tallow fatty acids. Other suitable anionic surfactants are sulfonated fatty acid glycerol esters, which are mono-, di- and triesters and their mixtures, such as those produced by esterification by a monoglycerol with 1 to 3 mol of fatty acid or in the transesterification of triglycerides with 0.3 to 2 mol of glycerol can be obtained.

In a preferred embodiment of the invention, the agents can contain anionic surfactants of the alkyl and / or alkenyl sulfate type. These anionic surfactants are to be understood as the sulfation products of primary alcohols which follow the formula (I)

[R ⁵ -O-SO ₃ -] _w Y ^{w +} (I),

in the m for 1 or 2 and R ⁵ for a linear or branched, aliphatic alkyl and / or alkenyl radical having 6 to 22, preferably 12 to 18 carbon atoms and Y for is an alkali and / or alkaline earth metal, ammonium, alkylammonium, alkanolammonium or glucammonium.

Typical examples of alkyl sulfates that can be used in the context of the invention are the sulfation products of capronalcohol, caprylic alcohol. Caprinal alcohol. 2-ethylhexyl alcohol, lauryl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidyl alcohol, petroselinyl alcohol, arachyl alcohol, gadoleyl alcohol, behenyl alcohol and erucyl alcohol, as well as their technical mixtures or the synthesis of high-pressure hydrogenation from aldehyde oxyhydrogenation. The sulfation products can preferably be used in the form of their alkali metal salts, and in particular their sodium salts. Particularly preferred are alkyl sulfates based on C ₁₆ -C _lg - tallow or vegetable fatty alcohols of comparable carbon chain distribution in the form of their sodium salts.

In addition, 2,3-alkyl sulfates, which are the US Patents US-A-3,234,258 or US-A-5,075,041, prepared for example in accordance and can be obtained as commercial products from Shell Oil Company under the name DAN ^®, are suitable anionic surfactants.

The sulfuric acid monoesters of the straight-chain or branched C ₇ -C ₂ alcohols ethoxylated with 1 to 6 mol ethylene oxide, such as 2-methyl-branched C ₉ -C _π alcohols with an average of 3.5 mol ethylene oxide (EO) or C ₁₂ - C _I8 fatty alcohols with 1 to 4 EO are suitable. Because of their high foaming behavior, they are used in detergents only in relatively small amounts, for example in amounts of 1 to 5% by weight.

Preferred anionic surfactants are also the salts of alkylsulfosuccinic acid, which are also referred to as sulfosuccinates or as sulfosuccinic acid esters and which represent monoesters and / or diesters of sulfosuccinic acid with alcohols, preferably fatty alcohols and in particular ethoxylated fatty alcohols. Preferred sulfosuccinates contain C ₈ -C. Fatty alcohol residues _oc ι _he 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 whose fatty alcohol residues 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. Fatty acid derivatives of amino acids, for example of N-methyl taurine (taurides) and / or of N-methyl glycine (sarcosides) 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, 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. In particular, those soap mixtures are preferred which are composed of 50 to 100% by weight of saturated C ₁₂ -C ₂₄ fatty acid soaps and 0 to 50% by weight of oleic acid soap.

The anionic surfactants and soaps can be present in the form of their sodium, potassium or ammonium salts and 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.

Nonionic alkoxylated alkyl and / or alkylaryl compounds are particularly suitable as nonionic surfactants. Typical further examples of nonionic surfactants are fatty koholpolyglycolether, alkylphenol, fatty acid, Fettsäurea- midpolygylcolether, fatty amine polyglycol ethers, alkoxylated triglycerides, mixed ethers, alk (en) yl oligoglycosides, fatty acid N-alkyl glucamides, polyol, Zuckerester, sorbitan esters and polysorbates. If the nonionic surfactants contain polyglycol ether chains, they can have a conventional, but preferably a narrow, homolog distribution.

Alkoxylated, advantageously ethoxylated, in particular primary alcohols with preferably 8 to 18 carbon atoms and an average of 1 to 12 moles of ethylene oxide (EO) per mole of alcohol are used, in which the alcohol radical can be linear or preferably methyl-branched in the 2-position or linear and may contain 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, palm kernel, tallow or oleyl alcohol, and an average of 2 to 8 EO per mole of alcohol preferred. The preferred ethoxylated alcohols include, for example, C ₁₂ -C ₁₄ alcohols with 3 EO or 4 EO, C ₉ -C _π alcohols with 7 EO, C _I3 -C _{I5 alcohols} with 3 EO, 5 EO, 7 EO or 8 EO, C ₁₂ -C ₁₈ - alcohols with 3 EO, 5 EO or 7 EO and mixtures of these, such as mixtures of C ₁₂ -C ₁₄ alcohol with 3 EO and C, ₂ -C ₁₈ alcohol with 7 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 EO can also be used. Examples of these are (tallow) fatty alcohols with 14 EO, 16 EO, 20 EO, 25 EO, 30 EO or 40 EO.

In addition, alkyl glycosides of the general formula RO (G) can also be used as further nonionic surfactants, in which R denotes a primary straight-chain or methyl-branched, in particular methyl-branched 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 carbon atoms, preferably for glucose. The degree of oligomerization x, which indicates the distribution of monoglycosides and oligoglycosides, is any number between 1 and 10; x is preferably 1.1 to 1.4.

Another class of preferably used nonionic surfactants, which are used either as sole nonionic surfactants or in combination with other nonionic surfactants, in particular together with alkoxylated fatty alcohols and / or alkylglycosides, 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 esters, as described, for example, in Japanese patent application JP 58/217 598 or which are preferably prepared by the process described in international patent application WO-A-90/13533. C ₁₂ -C ₈ fatty acid methyl esters with an average of 3 to 15 EO, in particular with an average of 5 to 12 EO, are particularly preferred.

Nonionic surfactants of the amine oxide type, for example N-coconut alkyl-N, N-dimethylamine oxide and N-tallow alkyl-N, N-dihydroxyethylamine oxide, and the fatty acid alkanol amides can also be suitable. The amount of these nonionic surfactants is preferably not more than that of the ethoxylated fatty alcohols, in particular not more than half of them.

So-called gemini surfactants can be considered as further surfactants. These are generally understood to mean those 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 have a sufficient Have a distance so that they can act independently of each other. Such surfactants are generally characterized by an unusually low critical micelle concentration and the ability to greatly reduce the surface tension of the water. In exceptional cases, however, the term gemini surfactants means not only dimeric but also trimeric surfactants.

Suitable gemini surfactants 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 international patent application WO-A-96/23768. End group-capped 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-capped surfactants mentioned have good wetting properties and are low-foaming, so that they are particularly suitable for use in machine washing or cleaning processes.

Gemini-polyhydroxyfatty acid amides or poly-polyhydroxyfatty acid amides, as described in international patent applications WO-A-95/19953, WO-A-95/19954 and WO-A-95/19955, can also be used.

Substances are used as cationic surfactants in which the high molecular weight hydrophobic residue which causes the surface activity is in the cation during dissociation in aqueous solution. The most important representatives of the cationic plasticizers are quaternary ammonium compounds of the general formula (R ₄ N ⁺ ) X ^" . Cationic plasticizers generally give the fiber a positive charge. This behavior is used for drawing up the cationic plasticizers, in particular on natural fibers, whereupon they have an enhancing effect Preferred cationic plasticizers are compounds of the formulas

In a preferred embodiment, alkylamidoammonium compounds are used as cationic plasticizers. Cationic plasticizers in which the central nitrogen atom of the cation is substituted by two long and two short residues are of particular importance. They show pronounced wetting, emulsifying and dispersing properties. Ammonium diester compounds are particularly preferred representatives. In a preferred embodiment, the compositions contain quaternary ammonium diester compounds and / or quaternary alkylamidoammonium compounds as textile softeners.

Typical examples of amphoteric or zwitterionic surfactants are alkyl betaines, alkyl amidobetaines, aminopropionates, aminoglycinates, imidazolinium betaines and sulfobetaines.

The surfactants mentioned are exclusively known compounds. With regard to the structure and production of these substances, reference is made to relevant reviews, for example, J. Falbe (ed.), "Surfactants in Consumer Products", Berlin, Springer Verlag, 1987, pp. 54-124 or J. Falbe (ed.), "Catalysts, Tenside und Mineralöladditive ", Stuttgart, Thieme Verlag, 1978, pp. 123-217.

Substances such as zeolites, crystalline layered silicates, silicates, phosphates and other layered silicates are suitable as builders.

The finely crystalline, synthetic and bound water-containing zeolite used is preferably zeolite A and / or P. Zeolite P is, for example, zeolite ^MAP® (Commercial product from Crosfield) is particularly preferred. However, zeolite X and mixtures of A, X and / or P are also suitable. Of particular interest is also a cocrystallized sodium / potassium aluminum silicate made of zeolite A and zeolite X. Which is commercially available as VEGOBOND AX ^® (commercial product from Condea) is. The zeolite can be used as a spray-dried powder or as an undried stabilized suspension that is still moist from its manufacture. If the zeolite is used as a suspension, it can contain small additions of nonionic surfactants as stabilizers, for example 1 to 3% by weight, based on zeolite, of ethoxylated C ₂ -C ₁₈ fatty alcohols with 2 to 5 Ethylene oxide groups, C ₁₂ -C ₁₄ fatty alcohols with 4 to 5 ethylene oxide groups or ethoxylated isotridecanols. 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.

Suitable substitutes or partial substitutes for phosphates and zeolites are crystalline layered sodium silicates of general formula NaMSi ₂ O ₊₁ ^■ y H ₂ O wherein 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 are 2, 3 or 4. Such crystalline layered silicates are described, for example, in European patent application EP-A-0 164 514. Preferred crystalline phyllosilicates of the formula given are those in which M is sodium and x is 2 or 3. In particular, both β- and δ-sodium disilicate Na ₂ Si ₂ O ₅ - Η ₂ O are preferred, with β-sodium disilicate being able to be obtained, for example, by the method described in international patent application WO-A-91/08171.

The preferred builder substances also include amorphous sodium silicates with a modulus Na ₂ O: SiO ₂ of 1: 2 to 1: 3.3, preferably of 1: 2 to 1: 2.8 and in particular of 1: 2 to 1: 2, 6, which are delayed release and have secondary washing properties. The delay in dissolution compared to conventional amorphous sodium silicates can be caused in various ways, for example by surface treatment, compounding, compacting / sealing 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. However, it can very well lead to particularly good builder properties if the silicate particles provide washed-out or even sharp diffraction maxima in electron diffraction experiments. This is so too interpret that the products have microcrystalline areas of size 10 to a few hundred nm, values up to max. 50 um and in particular up to max. 20 nm are preferred. Such so-called X-ray amorphous silicates, which also have a delay in dissolution compared to conventional water glasses, are described, for example, in German patent application DE-A-44 00 024. Compacted / compacted amorphous silicates, compounded amorphous silicates and over-dried X-ray amorphous silicates are particularly preferred.

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. Their content is generally not more than 25% by weight, preferably not more than 20% by weight, based in each case on the detergent composition. In some cases, it has been shown that tripolyphosphates in particular, even in small amounts up to a maximum of 10% by weight, based on the detergent composition, in combination with other builder substances lead to a synergistic improvement in the secondary washing ability. Preferred phosphate levels are at most 10% by weight, based on the detergent composition. Particularly preferred detergent compositions do not contain phosphates.

Further suitable substitutes or partial substitutes for the zeolite are layer silicates of natural and synthetic origin. Layered silicates of this type are known, for example, from patent applications DE-B-23 34 899, EP-A-0 026 529 and DE-A-35 26 405. Their usability is not limited to a special composition or structural formula. However, smectites, in particular bentonites, are preferred here.

Suitable layered silicates, which belong to the group of water-swellable smectites, are e.g. B. those of the general formulas

(OH) ₄ Si ₈ _yAly (Mg _J Al ₄ _) O ₂₀ montmorillonite, bentonite

(OH) ₄ Si _& _yA \ y (Al _{4 + y} ) O ₂₀ beidellite

(OH) ₄ Si ₈ _ _J Al _; (Mg ₆ _ ₂ -Li _z ) O ₂₀ hectorite

(OH) ₄ Si _g _yAly (Mg ₆ _ _z Al _z ) O ₂₀ saponite, stevensite

with x = 0 to 4, y = 0 to 2, z = 0 to 6. In addition, small amounts of iron can be incorporated into the crystal lattice of the layered silicates according to the above formulas. Furthermore, due to their ion-exchanging properties, the layered silicates may contain hydrogen, alkali and / or alkaline earth ions, in particular Na ⁺ and Ca ²⁺ . The hy The amount of third water is usually in the range of 8 to 20% by weight and depends on the swelling condition and the type of processing. Useful sheet silicates are known, for example, from US-A-3,966,629, EP-A-0 026 529 and EP-A-0 028 432. Layer silicates are preferably used which are largely free of calcium ions and strongly coloring iron ions due to an alkali treatment.

Layered silicates, preferably organically modified layered silicates, especially those which are anionically or cationically modified, in particular those which have been modified by the incorporation of quaternary ammonium compounds, are used as structuring agents in essentially non-aqueous liquid detergent compositions. As explained below, these can be activated with structure activators.

Organic builder substances which can be used as cobuilders 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 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 of detergents or 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, 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.

In the context 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 carried out against an external polyacrylic acid standard, which provides realistic molecular weight values due to its structural relationship with the investigated polymers. 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 20,000 g / mol. Because of their superior solubility, the short-chain polyacrylates with molecular weights of 2,000 to 10,000 g / mol, and particularly preferably 3,000 to 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 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. The (co) polymeric 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, for example, EP-B-0 727 448 allyloxybenzenesulfonic acid and methallylsulfonic acid, as monomers.

Also particularly preferred 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 or according to 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 German patent applications DE-A-43 03 320 and DE-A-44 17 734 and which preferably contain 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. Particularly preferred are polyaspartic acids or their salts and derivatives, of which it is disclosed in German patent application DE-A-195 40 086 that, in addition to cobuilder properties, they 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, for example as described in European patent application EP-A-0 280 223. Preferred polyacetals are made from dialdehydes such as glyoxal and glutaraldehyde. Terephthalaldehyde and mixtures thereof and obtained 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 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 owns. 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 2,000 to 30,000 g / mol can be used. 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 as well as international patent applications WO 92 / 18542, WO 93/08251, WO 93/16110, WO 94/28030, WO 95/07303, WO 95/12619 and WO 95/20608. An oxidized oligosaccharide according to German patent application DE-A-196 00 018 is also suitable. A product oxidized at C _{6 of} the saccharide ring can be particularly advantageous.

Oxydisuccinates and other derivatives of disuccinates, preferably ethylenediaminisisuccinate, are further suitable cobuilders. Ethylene diamine N, N'-disuccinate (EDDS), the synthesis of which is described, for example, in US Pat. No. 3,158,615, is preferably used in the form of its sodium or magnesium salts. Also preferred in this context are glycerol disuccinates and glycerol trisuccinates, as are described, for example, in US Pat. Nos. 4,524,009, 4,639,325, in European patent application EP-A-0 150 930 and in Japanese patent application JP 93/339 896. 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 a maximum of two acid groups. Such cobuilders are described, for example, in international patent application WO 95/20029.

Dirt-releasing polymers are preferably considered as additives. These oil and fat-dissolving so-called “soil repellents” include, for example, non-ionic cellulose ethers such as methyl cellulose and methyl hydroxypropyl cellulose with a proportion of methoxyl groups of 15 to 30% by weight and of hydroxypropoxyl groups of 1 to 15% by weight, based in each case on the nonionic cellulose ethers, 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, particularly preferably from these are the sulfonated derivatives of phthalic acid and terephthalic acid polymers The further preferred components are polymers which preferably contain ethylene terephthalate and / or polyethylene glycol terephthalate groups, the molar ratio of ethylene terephthalate to polyethylene glycol terephthalate being in the range from 50:50 to 90:10. The molecular weight of the linking polyethylene glycol units is preferably in the range from 750 to 5,000, i.e. that is, the degree of ethoxylation of the polymers containing polyethylene glycol groups can be approximately 15 to 100. The polymers are characterized by an average molecular weight of about 5000 to 200,000 and can have a block, but preferably a random structure.

Preferred polymers are those with molar ratios of ethylene terephthalate / polyethylene glycol terephthalate from about 65:35 to about 90:10, preferably from about 70:30 to 80:20. Also preferred are those polymers which have linking polyethylene glycol units with a molecular weight of 750 to 5,000 , preferably from 1,000 to about 3,000 and a molecular weight of the polymer from about 10,000 to about 50,000. Examples of commercially available polymers are the products Milease ™ T (ICI) or Repelotex ™ SRP 3 (Rhône-Poulenc). Sulfonated types from BASF are also suitable. In a preferred embodiment, modified polyethylene glycols, in particular butyl diglycol-modified polyethylene glycols, are used.

Other suitable ingredients of the agents are water-soluble inorganic salts such as bicarbonates, carbonates, amorphous silicates or mixtures of these; in particular Alkali carbonate and amorphous alkali silicate, especially sodium silicate with a molar ratio Na ₂ O: SiO ₂ from 1: 1 to 1: 4.5, preferably from 1: 2 to 1: 3.5, are used.

Foam inhibitors, phosphonates, enzymes and graying inhibitors can be contained in the detergent compositions as further detergent components, and solvents can also be contained in liquid detergents. Bleaches, bleach activators and bleach stabilizers can also be included; however, they reduce the effect of the colorant composition, so that the use of these substances is advantageously dispensed with. For this reason, the use of optical brighteners in the detergent compositions is of minor importance.

When used in machine washing processes, it can be advantageous to add conventional foam inhibitors to the agents. 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, optionally silanized silica, and paraffins, waxes, microcrystalline waxes and their mixtures with silanized silica or bistearylethylenediamide. Mixtures of various foam inhibitors are also used with advantages, for example those made of silicones, paraffins or waxes. The foam inhibitors, in particular silicone and / or paraffin-containing foam inhibitors, are preferably bound to a granular, water-soluble or dispersible carrier substance. Mixtures of paraffins and bistearylethylene diamides are particularly preferred.

The salts of polyphosphonic acids come into consideration as complexing agents or as stabilizers, in particular for enzymes which are sensitive to heavy metal ions. Here, the neutral reacting sodium salts of, for example, l-hydroxyethane-l, l-diphosphonate, diethylenetriaminepentamethylenephosphonate or ethylenediaminetetramethylenephosphonate in amounts of 0.1 to 3% by weight, preferably in amounts of 0.1 to 1.5% by weight. -%, used.

Particularly suitable enzymes are those from the class of hydrolases, such as proteases, esterases, lipases or lipolytically active enzymes, amylases, cellulases or other glycosyl hydrolases and mixtures of the enzymes mentioned. All of these hydrolases contribute to the removal of stains, such as stains containing protein, fat or starch, and graying in the laundry. Cellulases and other glycosyl hydrolases can be used for color preservation and removal by removing pilling and microfibrils contribute to increasing the softness of the textile. Oxidoreductases can also be used for bleaching or for inhibiting color transfer.

Bacterial strains or fungi such as Bacillus subtilis and Bacillus licheniformis are particularly suitable. Streptomyces griseus and Humicola insolens enzymatic active ingredients obtained. Proteases of the subtilisin type and in particular proteases obtained from Bacillus lentus are preferably used. Enzyme mixtures, for example, from protease and amylase or protease and lipase or lipolytically active enzymes or protease and cellulase or from cellulase and lipase or lipolytically active enzymes or from protease, amylase and lipase or lipolytically active enzymes or protease, lipase or lipolytically active enzymes and cellulase, in particular, however, mixtures containing protease and / or lipase or mixtures with lipolytically active enzymes of particular interest. Known cutinases are examples of such lipolytically active enzymes. Peroxidases or oxidases have also proven to be suitable in some cases. Suitable amylases include in particular α-amylases, iso-amylases, pullulanases and pectinases. Cellobiohydrolases, endoglucanases and β-glucosidases, which are also called cellobiases, or mixtures thereof, are preferably used as cellulases. Since the different cellulase types differ in their CMCase and avicelase activities, the desired activities can be set by targeted mixtures of the cellulases.

The enzymes can be adsorbed on carriers and / or embedded in coating substances in order to protect them against premature decomposition. The proportion of the enzymes, enzyme mixtures or enzyme granules can be, for example, approximately 0.1 to 5% by weight, preferably 0.1 to approximately 3% by weight, in particular 0.1 to approximately 2% by weight.

Graying inhibitors have the task of keeping the dirt detached from the fiber 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 carboxylic 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, for example 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 methyl hydroxyethyl cellulose and methyl hydroxypropyl cellulose are preferred. se, methyl carboxymethyl cellulose and mixtures thereof, and also polyvinylpyrrolidone, for example in amounts of 0.1 to 5% by weight, based on the composition.

Substantially non-aqueous liquid detergents contain up to 5% by weight, preferably up to 3% by weight, of free water. Preferred solid detergent compositions contain up to 25% by weight, preferably up to 15% by weight, of free water. In addition, the aqueous liquid detergent compositions can contain an organic solvent of mono- or polyhydric alcohols with 1 to 4 carbon atoms.

Dipropylene glycol monomethyl ether is preferably used as the organic solvent. Polydiols, ethers, alcohols and / or esters, in amounts of 0.1 to 60% by weight, preferably 0.1 to 40% by weight, in particular 0.1 to 30% by weight. Liquid nonionic surfactants are preferably used as washing-active substances.

In essentially non-aqueous liquid detergent compositions, the layered silicates which serve as structuring agents, preferably organically modified, can be activated with structuring activators. Structural activators generally improve the gel formation of the layered silicates. In many cases, such a chemical activator is helpful in order to separate the layer silicates normally present as platelets or platelet stacks and to achieve dispersion. Particularly suitable structural activators are low molecular weight polar substances, preferably polar organic solvents such as methanol, ethanol, propylene carbonate, acetone, acetonylacetone, diacetone alcohol, ethyl acetate, 2-propanol, dipropylene glycol monomethyl ether and dimethylformamide or mixtures thereof with at most 10% by volume of water , in particular 2 to 7 wt .-% water, based on the mixture of polar organic solvents with water. The structure activators are present in amounts of at least 35% by weight, based on the optionally organically modified layered silicates. Preferred amounts of structural activators are more than 50% by weight, preferably more than 60% by weight, based on the optionally organically modified layered silicates.

In aqueous textile plasticizer dispersions, it is expedient, if the dispersions do not already have a low initial viscosity, for example by using quaternary ammonium compounds with a high cis / trans ratio, to set a low viscosity by adding an electrolyte. Suitable electrical Trolytes are, for example, sodium chloride, sodium acetate, magnesium sulfate or calcium chloride and in particular magnesium chloride. Small amounts are also sufficient to set a low initial viscosity by adding an electrolyte. The electrolyte is present in the dispersion, for example, in concentrations of 0.01 to 3% by weight, based on the finished dispersion.

The agents can optionally contain, as optical brighteners, derivatives of diaminostilbenedisulfonic acid or its alkali metal salts. Are suitable for. B. Salts of 4,4'-bis (2-anilino-4-morpholino-l, 3,5-triazinyl-6-amino) stilbene-2,2'-disulfonic acid or similar compounds, instead of the morpholino group carry a diethanolamino group, a methylamino group, an anilino group or a 2-methoxyethylamino group. In addition, brighteners of the substituted diphenylstyryl type may be present, e.g. 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) diphenyls. Mixtures of the aforementioned brighteners can also be used. However, preferred detergent compositions do not contain optical brighteners.

For the case, which is not preferred according to the invention, that the detergent composition contains bleaches, bleach activators and bleach stabilizers, typical representatives of these substance classes are briefly presented here.

Among the compounds which serve as bleaching agents and supply H ₂ O ₂ in water, sodium perborate tetrahydrate and sodium perborate monohydrate are of particular importance. Further bleaching agents that 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.
