Definitions

• the present invention relates to a stable, liquid detergent with a textile-softening effect for simultaneous washing and care of delicates in the washing machine or by hand.
• the washing effect of such combinations is particularly good if the ratio of the nonionic surfactant to the quaternary ammonium compound is in the ratio 4: 1 to 1: 1.
• a liquid detergent with a combination of a nonionic surfactant, a conventional softening quaternary ammonium compound with one or two long-chain alkyl radicals and a further quaternary ammonium compound with a methyl group, one or two long-chain alkyl groups and two or a polyglycol ether group is described in DE-OS 24 26 581 described.
• a liquid detergent with a combination of a nonionic surfactant of the alkyl polyglycol ether or alkylphenol polyglycol ether type and a conventional fabric softener of the difatty alkyl dimethyl ammonium halide type and a fatty acid polyglycol diester is also known from DE-OS 25 29 444.
• German patent application P 28 17 834.9 proposes a liquid detergent with a detergent component made from two specific nonionic surfactants of the ethoxylated long-chain alcohol type and with a plasticizing component from a quaternary ammonium compound.
• the quaternary ammonium compound used is in particular ammonium salts with two long-chain alkyl or alkenyl and two short-chain alkyl groups, especially those compounds whose long-chain residues are derived from saturated or unsaturated tallow fatty alcohols.
• these are alkyl or alkenyl groups with essentially 16 and 18 carbon atoms, i.e. around palmityl, palmitoleyl, stearyl, oleyl and linoleyl residues.
• the consumer In addition to satisfactory washing properties, the consumer also demands from a modern liquid detergent that it is safe to use, easy to dose and stable in storage, and that its appearance and smell meet the expectations of the consumer. In particular, high demands are placed on the perfuming of a detergent by the consumer. Not only does the cheap absorption of a detergent often depend on whether it has a pleasant fragrance, but the detergent fragrance also has the application-specific task of masking the often unpleasant smell of detergent during washing, and that which is aimed at in the case of freshly washed, moist and dried laundry Complement the washing result with a laundry smell that conveys the impression of cleanliness and freshness.
• the person skilled in the art also knows the derivatives of the unhardened tallow alcohol, which in particular contains oleyl but also palmitoleyl and linoleyl radicals in a proportion of about 45%, as useful textile plasticizers.
• the mixtures produced with this type of compound have the desired viscosity properties, which are also largely independent of the cold, the perfumed mixtures are not stable in storage, which manifests itself in a change in fragrance to an unpleasant smell and in a change in color of the liquid.
• the same observations were made with the corresponding imidazolinium compounds with saturated or - at least partially - unsaturated long-chain aliphatic groups.
• alkyl polyglycol ethers of the formula I which are suitable according to the invention as constituent a) are derived from alcohols which are prepared by reacting linear olefins with carbon monoxide and hydrogen by the known oxo process by hydroformylation and exclusively hydrogenation.
• Commercially available oxo-alcohol mixtures which are suitable for the preparation of the surfactant component a) are, for example, the oxo alcohols available from Deutsche Shell Chemie Deutschen under the trade name "Dobanol", which have about 25% by weight of 2-alkyl branches.
• Other suitable oxo alcohols are available under the name "Synprol” from Imperial Chemical Industries Ltd. available alcohol mixtures with about 50-70 wt .-% 2-alkyl branches.
• Suitable products based on oxo alcohols are e.g. various "Lutensol” types from BASF with approx. 30-35% by weight of branched alcohols and some "Lial” types from Liquichimica S.p.A. with about 60 wt .-% branched alcohols.
• component a) are alkyl polyglycol ethers which represent ethylene oxide condensates of the aforementioned oxo alcohols with 13-15 carbon atoms with an average ethylene oxide content of approximately 55-65% by weight.
• Typical preferred products are, for example, "Dobanol 45-7”, which consists of at least 95% C 14 / C 15 oxo alcohol with an average of 7 moles of ethylene oxide, and "Lutensol AO-8", which is a C 13 / C 15 oxo alcohol Ethoxylate with an average of 8 moles of ethylene oxide.
• alkyl polyglycol ethers are preferred, the alcohol base of which is natural or synthetic primary fatty alcohols or oxo alcohols, which contain 9-12 carbon atoms and have an ethylene oxide content of approx. 60-70% by weight.
• Typical preferred products are, for example, the commercial product "Marlipal KF,” (Chemische Werke Huls), which is a C 10 / C 12 fatty alcohol ethoxylate with an average of 6 moles of ethylene oxide, and the "Lutensol ON-70,” which is a C 9 / C 11 -oxo represents alcohol ethoxylate with an average of 7 moles of ethylene oxide.
• Suitable fatty alcohols as the basis for preferred alkyl polyglycol ethers are also the commercial products "Lorol C-8 to 12" (Henkel).
• the ratio of the amount of component a) used to the amount of component b) essentially determines the parameters of washing power, foaming behavior and softening effect. Optimal results are obtained when the ratio of a): b) is between about 2: 1 and 1: 2.
• US Pat. No. 3,691,081 describes a detergent mixture intended for industrial use, the surfactant component of which consists of a liquid mixture of longer-chain and shorter-chain primary alcohol ethoxylates.
• the longer-chain alcohol ethoxylates are C 11 to C 20 oxo alcohols with 5-10 mol of ethylene oxide, and the shorter-chain alcohols are derived from C 6 to C 10 alcohols, which also have 5-10 mol of ethylene oxide, where the main part is derived from C 7 to C s alcohols.
• the person skilled in the art can see a liquid, biodegradable nonionic surfactant mixture which is a substitute for the known, non-degradable alkylphenol ethoxylates.
• the quaternary ammonium compounds which are suitable according to the invention as component c) can be obtained by reacting 1 mol of methylamine with 2 mol of C 16 / C 18 epoxide, which is obtainable by epoxidation of the corresponding ⁇ -olefin, and subsequent quaternization.
• liquid detergents which contain the quaternary ammonium compounds of the formula II as component c) in combination with the two nonionic surfactants of the formula I as components a) and b) have an optimum in terms of detergency, softening action, and foam behavior in connection with easy perfumability, good storage stability and low viscosity even at low temperatures.
• the agents according to the invention also have the further advantage that they have an optically appealing haze without the addition of special opacifiers, which are considered undesirable ballast in terms of washing technology and usually also have a problematic odor.
• Water is preferably used as the solvent for the liquid detergents according to the invention.
• organic solvents can also be used in amounts of up to 20% by weight of the total liquid detergent. But even with much lower additions of the organic solvent, which are of the order of 5% by weight, mixtures can be produced which have perfect properties.
• Lower alkanols or lower diols or polyols such as, for example, ethanol, isopropyl alcohol, ethylene glycol, propylene glycol or glycerol are particularly suitable as additional solvents.
• polyols with ether compounds such as methyl, ethyl, butyl or diethylene glycol or their acetates (for example products of the "Cellosolve” type from Union Carbide Corp.) can also be used.
• Formalin is usually used as a preservative in an amount of 0.05-1% by weight.
• complexing agents for heavy metal ions are added.
• Common complexing agents are Sodium, potassium or triethanolamine salts of aminopolycarboxylic acids, such as, for example, ethylenediaminetetraacetic acid or nitrilotriacetic acid. They are used in amounts of 0.1 to 1% by weight.
• Suitable fragrances are substances with a floral / fresh or fruity fragrance or those designated as cosmetic or creamy.
• Suitable dyes are e.g. water-soluble red xanthene dyes, such as rhodamine B-extra.
