Description

The invention relates to a textile treatment composition containing a special biocidal compound, a perfume composition and a nonionic surfactant in an amount between 0.75 and 1.5% by weight, the nonionic surfactant having an HLB value between 10.5 and 15 and a cloud temperature of at least 50 ° C, the textile treatment agent is a fabric softener and contains a softening component, the textile treatment agent additionally contains 0.5 to 5% by weight of ethanol and / or isopropanol and the nonionic surfactant is an alkoxylated fatty alcohol. The invention also relates to a method for producing the textile treatment agent.

The adhesion of microorganisms to surfaces is undesirable, especially in the case of pathogenic microorganisms. Adherent microorganisms often lead to infections or reinfection in humans, animals and plants.

Delicate textiles, such as silk or microfibre, are being processed into garments that can only be washed at 30 or 40 ° C. This does not kill fungi, such as the human pathogenic Candida albicans .

In addition to the lower washing temperature, the use of liquid detergents, which are usually free of bleaching agents, is also common today. When washing at 60 ° C, as was the rule in the past, almost all germs were reliably destroyed, on the one hand by the higher temperature and on the other hand by the bleaching agents contained in the commonly used universal detergents.

Thus, the changed washing behavior with viruses, bacteria, mold or yeast contaminated textiles can not be made germ-free to the extent necessary, so that under certain circumstances (re) infection can occur when the consumer comes into contact with the supposedly clean laundry.

Antimicrobial compositions and their use in detergents or cleaning agents are known in the prior art. These are, for example, textile treatment agents that contain one or more biocidal agents and are added to the rinse cycle.

The biocidal compounds used or their commercially available forms often have a pungent odor, which consumers often rate negatively on the product itself, but also on the textiles treated with it. However, the addition of a perfume composition leads to unstable products, especially at low storage temperatures.

This is how the international registration describes WO 99/27050 A1 Fabric softener containing a perfume composition, a nonionic surfactant and a biocidal compound in the form of ethanol. However, a fabric treatment composition with the specific biocidal compounds of the present invention is not described.

The international registration WO 99/55813 A1 describes a textile treatment agent containing a perfume, a biocidal agent and a surfactant, however, in contrast to the agents of the present invention, these textile treatment agents are not stable in storage.

It is therefore an object of the present invention to provide a stable textile treatment agent which comprises a biocidal compound and a perfume composition.

2. (ii) ein Benzalkoniumchlorid mit C₈-C₁₈-Alkylresten ist, das Textilbehandlungsmittel ein Weichspüler ist und eine weichmachende Komponente enthält, das Textilbehandlungsmittel zusätzlich 0,5 bis 5 Gew.-% Ethanol und/oder Isopropanol enthält und das nichtionische Tensid ein alkoxylierter Fettalkohol ist.

This object is achieved by a biocidal textile treatment agent containing a biocidal, quaternary ammonium compound, a perfume composition and a nonionic surfactant, the nonionic surfactant having an HLB value (according to Griffin) between 10.5 and 15 and a turbidity temperature of at least 50 ° C ( determined according to DIN 53917) and is contained in an amount between 0.75 and 1.5% by weight and the biocidal, quaternary ammonium compound

1. (i) a dialkyldimethylammonium chloride or
2. (ii) is a benzalkonium chloride with C ₈ -C ₁₈ alkyl radicals, the textile treatment agent is a fabric softener and contains a softening component, the textile treatment agent additionally contains 0.5 to 5% by weight of ethanol and / or isopropanol and the nonionic surfactant is an alkoxylated one Is fatty alcohol.

It has now surprisingly been found that the addition of a nonionic surfactant in an amount between 0.75 and 1.5% by weight, which has an HLB value (according to Griffin) between 10.5 and 15 and a certain turbidity temperature of at least 50 ° C ( determined according to DIN 53917), can effectively stabilize a textile treatment agent which contains a certain biocidal, quaternary ammonium compound and a perfume composition. It has been found that the stabilization does not occur if the nonionic surfactant has only one of the two properties.

It is preferred that the nonionic surfactant have an HLB value (according to Griffin) between 11 and 14 and more preferably between 11 and 13.

Nonionic surfactants with an HLB value (according to Griffin) in this range and a cloud temperature of at least 50 ° C (determined according to DIN 53917) stabilize textile treatment agents with a certain biocidal, quaternary ammonium compound and a perfume composition particularly effectively.

The nonionic surfactant is an alkoxylated fatty alcohol. Most preferably, the nonionic surfactant is an ethoxylated and / or propoxylated C ₁₂ -C ₁₈ fatty alcohol.

Alkoxylated fatty alcohols can not only particularly effectively stabilize the textile treatment agent, which comprises a biocidal compound and a perfume composition, but are also widely available commercially and therefore also inexpensive in many cases.

It is preferred that the ratio of nonionic surfactant to perfume is greater than or equal to 5: 1. It is more preferred that the ratio of nonionic surfactant to perfume is greater than 6: 1, more preferably between 15: 1 and 8: 1 and even more preferably between 12: 1 and 9: 1.

Particularly advantageous textile treatment agents are obtained when the ratio of nonionic surfactant to perfume composition is in a certain range. The textile treatment agents obtained are sufficiently stable, but do not have an unfavorable foaming behavior.

The textile treatment agent is a fabric softener.

The textile treatment agent contains a softening component.

It is very particularly preferred that the plasticizing component is an alkylated, quaternary ammonium compound, at least one alkyl chain being interrupted by an ester or amido group.

Fabric softeners only come into contact with the textiles in the last step of a conventional textile washing process, the rinse cycle.

The biocidal compound is selected from the group consisting of quaternary ammonium compounds.

These biocidal compounds are effective against viruses, bacteria, mold or yeast.

The textile treatment agent additionally contains 0.5 to 5, preferably 1 to 2.5% by weight, ethanol and / or isopropanol.

Ethanol and isopropanol themselves have an antimicrobial effect and thus expand the spectrum of action of the textile treatment agent. In addition, they also act as an emulsifier for the perfume and support the nonionic surfactant in stabilizing the textile treatment agent.

2. (ii) is a benzalkonium chloride with C ₈ -C ₁₈ alkyl radicals,

and a plasticizing component and 0.5 to 5 wt .-% ethanol and / or isopropanol.

In the context of this application, a biocidal compound is understood to be a compound which has an antimicrobial effect and which reduces the number of microorganisms on textile fabrics treated with it and in the washing liquor.

Depending on the antimicrobial spectrum and mechanism of action, a distinction is made between biocidal compounds according to bacteriostatics and bactericides, fungistatics and fungicides etc. Suitable biocidal compounds are preferably selected from the group of quaternary ammonium compounds.

The biocidal compound is a quaternary ammonium compound. The quaternary ammonium compounds (QAV) suitable as biocidal active ingredients have the general formula (R ¹ ) (R ² ) (R ³ ) (R ⁴ ) N ⁺ X ^- , in which R ¹ to R ^{4 are} identical or different C ₁ -C Represent ₂₂ alkyl radicals or C ₇ -C ₂₈ aralkyl radicals and X ^{- are} halide ions.

QACs can be prepared by reacting tertiary amines with alkylating agents such as methyl chloride or benzyl chloride. The alkylation of tertiary amines with a long alkyl radical and two methyl groups is particularly easy, and the quaternization of tertiary amines with two long radicals and one methyl group can also be carried out with the aid of methyl chloride under mild conditions.

Suitable QACs are, for example, dialkyldimethylammonium chlorides such as di- n- decyldimethylammonium chloride ( CAS No. 7173-51-5-5 ), Dioctyldimethylammonium chloride. The QAC are dialkyldimethylammonium chlorides, in particular di- n- decyldimethylammonium chloride, and the benzalkonium chlorides with C ₈ -C ₁₈ -alkyl radicals, in particular C ₁₂ -C ₁₄ -alkylbenzyldimethylammonium chloride. In addition to the fact that these biocidal compounds are effective against numerous microorganisms, the cationic compounds are particularly effective on cotton-containing fabrics and blended fabrics.

The dialkyldimethylammonium halides, the benzalkonium halides and / or substituted benzalkonium halides are commercially available, for example, as Barquat® ex Lonza, Marquat® ex Mason, Variquat® ex Evonik Industries and Hyamine® ex Lonza.

The biocidal, quaternary ammonium compound is used in an amount of 0.1 wt.% To 20 wt.%, Preferably 0.5 wt.% To 10 wt.% And particularly preferably 1 wt Wt .-% used. From a toxicological and ecological point of view, it is particularly preferred that the amount of biocidal compound is less than 2.5% by weight.

The textile treatment agent necessarily contains a perfume composition in order to give the laundry treated with it and the textile treatment agent itself a pleasant fragrance.

In a preferred embodiment, the textile treatment agent contains the perfume composition in an amount of usually up to 2% by weight, preferably 0.01 to 1% by weight, in particular 0.02 to 0.75% by weight and particularly preferably 0.04 up to 0.4% by weight.

The perfume composition can contain individual fragrance compounds, for example the synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type. However, mixtures of different fragrances are preferably used, which together produce an appealing fragrance. The perfume composition can also contain natural fragrance compounds, as are available from plant sources.

The perfume composition of the textile treatment agent may further contain at least one aromatherapy component. An essential oil can preferably be used as the aromatherapy component.

For example, essential oils are extracted from flowers, spices, herbs, woods or fibers and are complex mixtures of various organic molecules such as terpenes, ethers, coumarins, esters, aldehydes, phenyl esters, monoterpenols, phenols, monoterpenes, oxides, sesquiterpene ketones, sesquiterpenes and Sesquiterpenolen. Due to their small molecular structure, essential oils enter the bloodstream and tissue via the skin and / or mucous membrane. In this way, they can influence the entire organism.

A large number of essential oils can be used in the textile treatment agents according to the invention. Suitable essential oils include, for example, oils from Abies Sibirica, Amyris Balsamifera, anise (Illicium Verum), lemon balm (Melissa Officinalis), basil (Ocimum Basilicum), pimenta acris, bee balm (Monarda Didyma), bergamot (Citrus Aurantium Bergamula), birch (Betam Aba), bitter orange (Citrus Aurantium Amara), hibiscus, hundred-petalled rose (Rosa Centifolia), Calendula Officinalis, Californian nutshell (Torreya Californica), Camellia Sinensis, Capsicum Frutescers Oleoresin, caraway (Carum Carvi), cardamom (Elettaria cardamholz) Cedrus Atlantica), Chamaecyparis Obtusa, Chamomile (Anthemis Nobilis), Cinnamon (Cinnamomum Cassia), Lemongrass (Cymbopogon Nardus), Clary Sage (Salvia Sclarea), Clove (Eugenia Caryophyllus), Coriander (Coriandus Escorulentum, Cyperus Sativum) Cupressus sempervirens), Eucalyptus Citriodora, Eucalyptus Globulus, Fennel (Foeniculum Vulgare), Gardenia Florida, Geranium Maculatum, Ginger (Zingiber O fficinale), camelina (Camelina sativa), grapefruit (Citrus Grandis), hops (Humulus Lupulus), Hypericum perforatum, Hyptis Suaveolens, indigo shrub (Dalea Spinosa), jasmine (Jasminum officinale), Juniperus Communis, Juniperus Virginiana, Labdanum (Cist Labdaniferus), Laurel (Laurus Nobilis), Lavandin (Lavandula Hybrida), Lavender (Lavandula Angustifolia), Lemon (Citrus Medica Limonum), Lemongrass (Cymbopogon Schoenanthus), Leptospermum Scoparium, Lime (Citrus Aurantifolia), Linden (Tilia Cord Cubeba, Lovage (Levisticum Officinale), Citrus Nobilis, Massoy Bark, Chamomile (Chamomilla Recutita), Moroccan Chamomile, Musk Rose (Rosa Moschata), Myrrh (Commiphora Myrrha), Myrtle (Myrtus Communis), Picea Excelsa, Muscat (Myristica) Fragrance Olax Dissitiflora, Olibanum, Opoponax, Orange (Citrus Aurantium Dulcis), Palmarosa (Cymbopogon Martini), Parsley Seeds (Carum Petroselinum), Passiflora (Passiflora Incarnata), Patchouli (Pogcstemon Cablin), Pe largonium graveolens, common mint (Mentha pulegium), peppermint (Mentha piperita), pine (Pinus palustris), pinus pinea, pinus pumiho, pinus sylvestris, rosemary (rosmarinus officinalis), rose, rosewood (aniba rosseodora), rue (ruta graveolens) Sage (Salvia Officinalis), Sambucus Nigra, Sandalwood (Santalum Album), Sandarak (Callitris Quadrivalvis), Sassafras Officinale, Sisymbrium Ino, Spearmint (Mentha Viridis), Marjoram (Origanum Majorana), March Violets (Viola Odorata), Occidentalis, Occidental Thyme (Thymus Vulgaris), Vetiveria Zizanoides, Wild Mint (Mentha Arvensis), Ximenia Americana, Yarrow (Achillea Millefolium), Ylang Ylang (Cananga Odorata) and mixtures thereof.

As a further essential component, the textile treatment agent contains a nonionic surfactant with an HLB value (according to Griffin) between 10.5 and 15 and a cloud temperature of at least 50 ° C (determined according to DIN 53917) in an amount between 0.75 and 1.5% by weight. , which is an alkoxylated fatty alcohol.

The HLB value (English abbreviation for "hydrophilic-lipophilic balance") describes the hydrophilic and lipophilic content of mainly nonionic surfactants and was proposed in 1954 by W. C. Griffin.

wobei M_I die Molmasse des hydrophilen Anteils eines Moleküls ist und M die Molmasse des gesamten Moleküls. Der Faktor 20 ist ein von Griffin frei ausgewählter Skalierungsfaktor. Es ergibt sich damit in der Regel eine Skala von 1 bis 20. Ein HLB-Wert von 1 spricht für eine lipophile Verbindung, eine chemische Verbindung mit einem HLB-Wert von 20 hat einen hohen hydrophilen Anteil.The HLB value for nonionic surfactants can be calculated as follows: $$\mathrm{HLB}=20\times {\mathrm{M}}_{\mathrm{I}}/\mathrm{M}$$

where M _{I is} the molecular weight of the hydrophilic portion of a molecule and M is the molecular weight of the entire molecule. The factor 20 is a scaling factor freely chosen by Griffin. This usually results in a scale from 1 to 20. An HLB value of 1 speaks for a lipophilic compound, a chemical compound with an HLB value of 20 has a high hydrophilic content.

The water solubility of surfactants is reduced by increasing temperatures. The loose complex bond between the hydrophilic areas of the surfactant (for example, the polyglycol ether chain in the case of an ethoxylated surfactant) and the water molecules, as a result of which water solubility is brought about, is more or less dissolved by the increasing molecular movement. This process is reversible. The turbidity temperature is the temperature at which an aqueous solution of a surfactant suddenly becomes cloudy when heated. The determination is made according to DIN 53917.

For water-soluble surfactants, the turbidity temperature is determined from a 1% aqueous solution. If the degree of alkoxylation is very high, the turbidity temperature must be determined in a NaCl solution.

Non-ionic surfactants with an HLB value (according to Griffin) between 10.5 and 15 and a turbidity temperature of at least 50 ° C (determined according to DIN53917) are alkoxylated, advantageously ethoxylated, in particular primary alcohols with preferably 8 to 18 carbon atoms and average 3 to 12 moles of ethylene oxide (EO) are used per mole of alcohol, in which the alcohol radical is linear. However, alcohol ethoxylates with linear residues of alcohols of native origin with 12 to 18 carbon atoms, for example from coconut, palm, tallow fat or oleyl alcohol, and an average of 4 to 8 EO per mole of alcohol are particularly preferred. 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). A particularly preferred nonionic surfactant is a C _12-18 alcohol with 7 EO. This ethoxylated fatty alcohol has an HLB value of 11.9 and a turbidity temperature in the range from 50 to 56 ° C.

The amount of nonionic surfactant with an HLB value (according to Griffin) of between 10.5 and 15 and a haze temperature of at least 50 ° C (determined according to DIN 53917) in a textile treatment agent is between 0.75 and 1.5% by weight. A nonionic surfactant with an HLB value (according to Griffin) between 10.5 and 15 and a cloud temperature of at least 50 ° C (determined according to DIN 53917) is able to stabilize a scented, biocidal textile treatment agent so effectively that it can be used in low , absolute amount can be used. This has the advantage that the risk is low that too much foam is formed in the wash cycle due to the presence of the foam-forming nonionic surfactants and remains on the laundry.

In preferred textile treatment agents, the ratio of nonionic surfactant to perfume is therefore greater than or equal to 5: 1, preferably greater than 6: 1, more preferably between 15: 1 and 8: 1 and particularly preferably between 12: 1 and 9: 1.

It has been shown in particular that with a nonionic surfactant to perfume ratio of greater than 6: 1, more preferably between 15: 1 and 8: 1 and particularly preferably between 12: 1 and 9: 1, the textile treatment agent is particularly well stabilized at storage temperatures between 0 and 10 ° C and especially at 0 ° C occurs.

In addition to the biocidal, quaternary ammonium compound, the perfume composition and the nonionic surfactant, the textile treatment agents can contain further ingredients which further improve the application technology and / or aesthetic properties of the textile treatment agent. In the context of the present invention, preferred textile treatment agents additionally contain one or more substances from the group of plasticizing components, thickeners, builders, electrolytes, non-aqueous solvents, pH adjusting agents, fluorescent agents, dyes, hydrotopes, foam inhibitors, silicone oils, anti-redeposition agents, optical brighteners, graying inhibitors, Anti-shrink agents, anti-crease agents, dye transfer inhibitors, antioxidants, preservatives, corrosion inhibitors, antistatic agents, bitter agents, ironing aids, phobing and impregnating agents, swelling and anti-slip agents, skin-care compounds and UV absorbers.

The textile treatment agent is a fabric softener and contains a softening component in addition to the biocidal, quaternary ammonium compound, the nonionic surfactant and the perfume composition.

The plasticizing component includes, for example, quaternary ammonium compounds such as monoalk (en) yltrimethylammonium compounds, dialk (en) yldimethylammonium compounds, mono-, di- or triesters of fatty acids with alkanolamines.

The polyacrylic and polymethacrylic thickeners include, for example, the high molecular weight homopolymers of acrylic acid crosslinked with a polyalkenyl polyether, in particular an allyl ether of sucrose, pentaerythritol or propylene (INCI name according to the "International Dictionary of Cosmetic Ingredients" of "The Cosmetic, Toiletry and Fragrance" Association (CTFA) ": Carbomer), which are also referred to as carboxyvinyl polymers. Such polyacrylic acids are available, inter alia, from 3V Sigma under the trade name Polygel®, for example Polygel DA, and from BF Goodrich under the trade name Carbopol®, for example Carbopol 940 (molecular weight approx. 4,000,000), Carbopol 941 (molecular weight approx.1,250,000) or Carbopol 934 (molecular weight approx.3,000,000). The following also include the following acrylic acid copolymers: (i) Copolymers of two or more monomers from the group consisting of acrylic acid, methacrylic acid and their simple esters (INCI acrylates copolymer), which are preferably formed with C _1-4 alkanols, to which, for example, the copolymers of methacrylic acid, butyl acrylate and methyl methacrylate (CAS name according to Chemical Abstracts Service: 25035-69-2) or of butyl acrylate and methyl methacrylate (CAS 25852-37-3) and which, for example, from Rohm & Haas under the trade names Aculyn® and Acusol® and from Degussa (Goldschmidt) under the trade name Tego® Polymer, for example the anionic non-associative polymers Aculyn 22, Aculyn 28, Aculyn 33 (crosslinked), Acusol 810, Acusol 820, Acusol 823 and Acusol 830 (CAS 25852-37-3); (ii) Crosslinked high molecular acrylic copolymers, for example the copolymers of C _10-30 alkyl acrylates crosslinked with an allyl ether of sucrose or pentaerythritol with one or more monomers from the group consisting of acrylic acid, methacrylic acid and their simple, preferably with C _1-4 -Alkanols formed, esters (INCI Acrylates / C _10-30 Alkyl Acrylate Crosspolymer) and which are available, for example, from BF Goodrich under the trade name Carbopol®, for example the hydrophobized Carbopol ETD 2623 and Carbopol 1382 (INCI Acrylates / C _{10 -30} alkyl acrylate crosspolymer) and Carbopol Aqua 30 (formerly Carbopol EX 473). Cationic poly (meth) acrylic thickeners are particularly preferably used.

Preferred textile treatment agents contain, based on the total textile treatment agent, 0.01 to 3% by weight and preferably 0.1 to 1% by weight of thickener. The amount of thickener used depends on the type of thickener and the desired degree of thickening.

A wide number of different salts can be used as electrolytes from the group of inorganic salts. Preferred cations are the alkali and alkaline earth metals, preferred anions are the halides and sulfates. From a manufacturing point of view, the use of NaCl or MgCl ₂ in the textile treatment agents is preferred. The proportion of electrolytes in the textile treatment agent is usually 0.01 to 2% by weight.

Non-aqueous solvents that can be used in the textile treatment agents come, for example, from the group of mono- or polyhydric alcohols, alkanolamines or glycol ethers, provided that they are miscible with water in the concentration range indicated. The solvents are preferably selected from ethanol, n- or i-propanol, butanols, glycol, propane or butanediol, glycerol, diglycol, propyl or butyl diglycol, hexylene glycol, ethylene glycol methyl ether, ethylene glycol ethyl ether, ethylene glycol propyl ether, ethylene glycol mono-n-butyl ether, diethylene glycol methyl ether, diethylene glycol methyl ether , Propylene glycol methyl, ethyl or propyl ether, dipropylene glycol monomethyl or ethyl ether, diisopropylene glycol monomethyl or ethyl ether, methoxy, ethoxy or butoxytriglycol, 1-butoxyethoxy-2-propanol, 3-methyl-3-methoxybutanol, propylene glycol t-butyl ether and mixtures of these solvents. Non-aqueous solvents can be used in the textile treatment agents in amounts between 0.5 and 15% by weight, but preferably below 9% by weight and in particular below 5% by weight.

The textile treatment agent additionally contains 0.5 to 5% by weight, preferably 1 to 2.5% by weight, of ethanol and / or isopropanol. Ethanol and isopropanol not only support the stabilization of the perfume composition, but also have a biocidal effect. This not only improves the stability of the textile treatment agent, but also extends the range of effects of the textile treatment agent.

The viscosity of the textile treatment agents can be measured using customary standard methods (for example Brookfield viscometer LVT-II at 20 rpm and 20 ° C., spindle 2) and is preferably 5 to 4000 mPas, values between 10 and 2000 mPas being particularly preferred , The viscosity of fabric softeners is particularly preferably from 10 to 1000 mPas.

In order to bring the pH value of the textile treatment agents into the desired range, the use of pH adjusting agents can be indicated. All known acids or bases can be used here, provided that their use is not prohibited for application-related or ecological reasons or for reasons of consumer protection.

To improve the aesthetic impression of the textile treatment agents, they can be colored with suitable dyes. Preferred dyes, the selection of which is not difficult for the person skilled in the art, have a high storage stability and insensitivity to the other ingredients of the textile treatment agents and to light, and no pronounced substantivity to textile fibers in order not to dye them.

Foam inhibitors that can be used in the textile treatment compositions are, for example, soaps, paraffins or silicone oils, which can optionally be applied to carrier materials.

Suitable soil release polymers, which are also referred to as "anti-redeposition agents", are, for example, nonionic cellulose ethers such as methyl cellulose and methyl hydroxypropyl cellulose with a proportion of methoxy groups of 15 to 30% by weight and of hydroxypropyl groups of 1 to 15% by weight, in each case based on the nonionic cellulose ether and the polymers of phthalic acid and / or terephthalic acid or their derivatives known from the prior art, in particular polymers of ethylene terephthalates and / or polyethylene and / or polypropylene glycol terephthalates or anionically and / or nonionically modified derivatives thereof. Suitable derivatives include the sulfonated derivatives of the phthalic and terephthalic polymers.

Optical brighteners (so-called "whiteners") can be added to the textile treatment agents in order to eliminate graying and yellowing of the treated textile fabrics. These substances absorb on the fiber and bring about a brightening and simulated bleaching effect by converting invisible ultraviolet radiation into visible longer-wave light, whereby the ultraviolet light absorbed from the sunlight is emitted as a slightly bluish fluorescence and pure with the yellow tone of the grayed or yellowed laundry White results. Suitable compounds originate, for example, from the substance classes of 4,4'-diamino-2,2'-stilbenedisulfonic acids (flavonic acids), 4,4'-distyryl-biphenyls, methylumbelliferones, coumarins, dihydroquinolinones, 1,3-diarylpyrazolines, naphthalic acid imides, benzoxazole , Benzisoxazole and benzimidazole systems and the pyrene derivatives substituted by heterocycles. The optical brighteners are usually used in amounts between 0% and 0.3% by weight, based on the finished washing and cleaning agent.

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 glue, gelatin, salts of 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 and hydroxyalkyl cellulose are preferred and mixed ethers such as methylhydroxyethyl cellulose, methyl hydroxypropyl cellulose, methyl carboxymethyl cellulose and mixtures thereof in amounts of 0.1 to 5% by weight, based on the textile treatment agents.

In order to effectively suppress dye detachment and / or dye transfer to other textiles during the treatment of colored textiles, the textile treatment agent may contain a color transfer inhibitor. It is preferred that the color transfer inhibitor is a polymer or copolymer of cyclic amines such as vinyl pyrrolidone and / or vinyl imidazole. Polymers suitable as color transfer inhibitors include polyvinylpyrrolidone (PVP), polyvinylimidazole (PVI), copolymers of vinylpyrrolidone and vinylimidazole (PVP / PVI), polyvinylpyridine-N-oxide, poly-N-carboxymethyl-4-vinylpyridium chloride and mixtures thereof. Polyvinylpyrrolidone (PVP), polyvinylimidazole (PVI) or copolymers of vinylpyrrolidone and vinylimidazole (PVP / PVI) are particularly preferably used as color transfer inhibitors. The polyvinylpyrrolidones (PVP) used preferably have an average molecular weight of 2,500 to 400,000 and are commercially available from ISP Chemicals as PVP K 15, PVP K 30, PVP K 60 or PVP K 90 or from BASF as Sokalan® HP 50 or Sokalan® HP 53 available. The copolymers of vinylpyrrolidone and vinylimidazole (PVP / PVI) used preferably have a molecular weight in the range from 5,000 to 100,000. A PVP / PVI copolymer is commercially available, for example, from BASF under the name Sokalan® HP 56.

The amount of color transfer inhibitor based on the total amount of the textile treatment agent is preferably from 0.01 to 2% by weight, preferably from 0.05 to 1% by weight and more preferably from 0.1 to 0.5% by weight.

In order to prevent undesirable changes in the textile treatment agents and / or the treated textile fabrics caused by the action of oxygen and other oxidative processes, the detergents and cleaning agents can contain antioxidants. This class of compounds includes, for example, substituted phenols, hydroquinones, pyrocatechols and aromatic amines as well as organic sulfides, polysulfides, dithiocarbamates, phosphites, phosphonates and vitamin E.

Increased wearing comfort can result from the additional use of antistatic agents, which are additionally added to the textile treatment agents. Antistatic agents increase the surface conductivity and thus enable the flow of charges that have formed to improve. External antistatic agents are generally substances with at least one hydrophilic molecular ligand and give a more or less hygroscopic film on the surfaces. These mostly surface-active antistatic agents can be divided into nitrogen-containing (amines, amides, quaternary ammonium compounds), phosphorus-containing (phosphoric acid esters) and sulfur-containing (alkyl sulfonates, alkyl sulfates) antistatic agents. Lauryl (or stearyl) dimethylbenzylammonium chlorides are suitable as antistatic agents for textile fabrics or as an additive to textile treatment agents, with an additional finishing effect.

To improve the rewettability of the treated textile fabrics and to facilitate ironing of the treated textile fabrics, silicone derivatives, for example, can be used in the textile treatment agents. These also improve the rinsing behavior of detergents and cleaning agents thanks to their foam-inhibiting properties. Preferred silicone derivatives are, for example, polydialkyl or alkylarylsiloxanes in which the alkyl groups have one to five carbon atoms and are wholly or partially fluorinated. Preferred silicones are polydimethylsiloxanes, which can optionally be derivatized and are then amino-functional or quaternized or have Si-OH, Si-H and / or Si-Cl bonds.

Furthermore, the textile treatment agent can comprise a skin-care compound.

A skin-care compound is understood to mean a compound or a mixture of compounds which, when a textile comes into contact with the detergent, absorb onto the textile and, when the textile comes into contact with the skin, give an advantage over the textile compared to a textile which is not treated with the textile treatment agent according to the invention has been. This advantage can include, for example, the transfer of the skin-care compound from the textile to the skin, less water transfer from the skin to the textile or less friction on the skin surface by the textile.

Finally, the textile treatment agents can also contain UV absorbers, which absorb onto the treated textile fabrics and improve the light resistance of the fibers. Compounds which have these desired properties are, for example, the compounds and derivatives of benzophenone which are active by radiationless deactivation and have substituents in the 2- and / or 4-position. Substituted benzotriazoles, phenyl-substituted acrylates (cinnamic acid derivatives), optionally with cyano groups in the 2-position, salicylates, organic Ni complexes and natural products such as umbelliferone and the body's own urocanoic acid are also suitable.

The preparation of the textile treatment agents can be obtained by techniques familiar to those skilled in the art for the production of fabric softeners, washing aids and post-treatment agents. This can be done, for example, by mixing the raw materials, if necessary using high-shear mixing equipment. In the case of fabric softeners as textile treatment agents, it is advisable to melt the softening component (s) and then disperse the melt in a solvent, preferably water. The other ingredients can be easily integrated into the fabric softener.
