Definitions

• the wearing comfort of textiles can be improved by applying small amounts of mostly cationic compounds to the textiles, which gives the textiles a pleasantly soft feel and antistatic properties.
• the cationic compounds can be applied both before the first wearing and after a wearing period, for example in connection with washing. It is thus possible to apply the cationic compounds to the textiles in a tumble dryer during washing, rinsing or drying.
• This fabric softener concentrate contains fabric softening quaternary ammonium compounds, an alkali metal soap or the corresponding fatty acids, glycerol and other water-soluble or water-miscible compatible organic solvents and water, the alkali metal soap or the corresponding fatty acid making up 1/70 to 1/3 of the amount of the fabric softening quaternary ammonium compounds, and the content of the quaternary ammonium compounds in the concentrate is at least 30% by weight and the concentrate is in flowable, meterable form.
• the distributability of the concentrates can be further improved if the concentrate contains quaternary ammonium compounds with two acyloxyalkyl groups, the acyl groups of which are derived from saturated or unsaturated carboxylic acids having 12 to 22 carbon atoms.
• Particularly suitable compounds contain acyl groups which are derived from tallow fatty acid, oleic acid, rapeseed oil or coconut oil.
• Typical representatives of this class of compounds are the compounds of the dimethyl-di (-2) type known, for example, from DE-OS-16 19 058, DE-OS 17 94 068, DE-OS 19 35 499 and DE-AS 24 30 140 -acyloxyalkyl-) ammonium methosulfate.

• the anion can, for example, also be the chloride, bromide or ethyl sulfate anion or be derived from phosphoric acid.
• the acyl groups are bonded to the nitrogen atom via oxyalkyl groups with 2 to 4 carbon atoms. In the case of oxyalkyl groups with 3 or 4 carbon atoms, the carbon chain can be linear or branched; Compounds with 3 carbon atoms in the branched carbon chain in particular are of particular importance. A typical preferred representative of these compounds is dimethyl-di-acyloxyisopropyl ammonium methosulfate.
• the last-mentioned compound has particularly valuable properties if the acyl group is derived from rapeseed oil fatty acid.
• the fabric softener concentrates also contain nonionic dispersants, which among other things improve the dispersibility of the active ingredients in water.

• those with two long-chain, saturated or unsaturated aliphatic groups each with 14 to 26, in particular essentially 16 to 20, carbon atoms and at least one quaternary nitrogen atom in the molecule are particularly suitable.
• the long-chain aliphatic groups can be straight-chain or branched and can accordingly derive from fatty acids or from fatty amines, Guerbetamines or from the alkylamines obtainable by reduction of nitroparaffins.
• These quaternary ammonium compounds are derivatives of ammonia, that is to say the quaternary salts obtainable by alkylation of long-chain secondary amines, such as, for.
• quaternary ammonium compounds are those obtained by reacting 1 mole of an aminoalkylethylenediamine or hydroxyalkylethylenediamine with 2 moles of a long-chain C14-C26 fatty acid or its ester imidazoline compounds, which are subsequently converted into the quaternary imidazolinium compounds by alkylation.
• the anion generally consists of the acid residue which has arisen from the alkylating agent used in the quaternization.
• chloride, bromide, methyl sulfate, ethyl sulfate, methane, ethane or toluenesulfonate are suitable as anions.
• the quaternary ammonium compounds are also good antistatic agents. Very good results are also obtained when the quaternary ammonium compounds are mixtures of imidazoline derivatives and ammonia derivatives each with two C14-C26 alkyl or alkenyl groups, especially if the imidazoline derivatives are two long-chain unsaturated groups, for example oleyl Groups included.
• the fatty acids mentioned as component b) are fatty acids with 8 to 20 carbon atoms. Both saturated and unsaturated fatty acids and also mixtures of saturated and unsaturated fatty acids can be contained in the concentrate according to the invention. Instead of or together with the fatty acids mentioned, the alkali metal salts, in general the sodium salts of the fatty acids mentioned, can also be used. Examples of suitable fatty acids or their alkali metal salts are mixtures which are 20% by weight of coconut fatty acid and derive to 80 wt .-% of tallow fatty acid or mixtures derived from 30 wt .-% of C16 fatty acids and 70 wt .-% of C18 fatty acids. These fatty acids and alkali soaps (b), in coordination with the quaternary ammonium compounds (a), are preferably present in such amounts that the weight ratio of a): b) is in the range from 20: 1 to 5: 1.
• a further essential constituent of the concentrates according to the invention is glycerol, concentrates whose proportion of soap b) and of glycerol c) taken together being 5 to 30% by weight are preferred.

• Liquid paraffin oil hydrocarbons are also suitable as emulsifiers.
• Other suitable emulsifiers are ether amines, fatty alcohol esters, benzyl alkanol polyglycol ethers.
• the concentrate according to the invention preferably has a pH of below 6. This is important insofar as the concentrate should expediently react with acid even after dilution with ten times the amount of water. Concentrates with a pH of 3 to 6 undiluted meet this requirement; they are therefore preferred. Acids compatible with textiles and the materials of washing machines, such as, for example, the inorganic acids, hydrochloric acid, sulfuric acid, phosphoric acid, boric acid or else the organic acids, such as, for example, formic acid, acetic acid, benzoic acid, lactic acid, glycolic acid and in particular, are suitable for adjusting the pH below 6 Citric acid suitable.

• the concentrate according to the invention is notable for good dilutability with water and for a good textile-softening effect. It is used by adding it in a concentration of 0.2 to 1 g per 1 to the last rinse water. With increasing number of carbon atoms in the oxyalkyl group of textile softeners essential to the invention, both the softening effect and the dispersibility in water increase. The simultaneous improvement of both properties is surprising, because in general an improvement in one property is at the expense of the other.
• Fabric softener concentrates with the following composition were produced: 45% by weight plasticizer 1% by weight Na tallow fatty acid 11.5 wt% glycerin 17.5% by weight isopropyl alcohol 6% by weight propylene glycol 1,2 3% by weight dipropylene glycol 1.5% by weight nonylphenol + 9.5 mol ethylene oxide 11.5% by weight water 3% by weight of perfume oil

• the distributability in water was also rated by two grades.
• the grade “1” meant “cloudy, homogeneous” and the grade “6” meant “coherent, clumping”.
• the first grade was given for the behavior when pouring into cold water, the second grade after stirring the poured product.
• the experimental results shown in Table 1 were obtained:
• Example 4 is best in terms of softening performance and water dispersibility, and all of the examples of the invention are better than Comparative Example 1.
