Patent ID: 8883712

Claim:
A fabric softening composition, comprising: a) as component A, at least one tertiary or quaternary ammonium salt, selected from compounds of formulae (I) and (II): R 1 R 2 R 3 N + CH 2 CHR 4 OC(═O)R 5 X − (I) R 1 R 2 R 3 N + (CH 2 ) 3 NHC(═O)R 5 X − (II) wherein: R 1 is hydrogen, methyl or ethyl, R 2 and R 3 , independently of one another, are a C 1-4 alkyl or C 2-4 hydroxyalkyl, R 4 is hydrogen or methyl, R 5 is a linear C 15-21 alkyl or alkenyl radical and X − is a monovalent anion, and b) as component B, at least one nonionic softener selected from the group consisting of fatty acids, monoesters of fatty acids with a C 2-6 diol or C 3-9 polyol, and monoesters of fatty alcohols with a C 2-6 hydroxycarboxylic acid, and wherein: i) the molar ratio of the total amount of component A to the total amount of component B is in the range from 2:1 to 1:3, ii) the difference between the average chain length of the long-chain hydrocarbon radicals of components A and B is at most 2 carbon atoms, iii) the hydrocarbon radicals of components A and B have on average in each case at most 0.5 double bonds per hydrocarbon radical and iv) the total amount of tertiary and quaternary ammonium salts carrying two long-chain hydrocarbon radicals of 15 to 21 carbon atoms in the composition is at most 80 mol % of the total amount of components A; v) wherein the total fraction of component A and component B in the composition is at least 50% by weight.
