Abstract
A fabric softening composition which comprises as component A a tertiary or quaternary ammonium salt of formulae (I) or (II):RRRNCHCHROC(═O)RX  (I)RRRN(CH)NHR(═O)RX  (II)in which Ris hydrogen, methyl or ethyl, Rand R, independently of one another, are Calkyl or Chydroxyalkyl, Ris hydrogen or methyl, Ris a linear Calkyl or alkenyl radical and Xis a monovalent anion, and as component B a nonionic softener with only one long-chain hydrocarbon radical bonded to a polar radical having at least one free hydroxy group, where fatty alcohol alkoxylate or fatty acid alkoxylate are excluded as component B, exhibits a good softening effect and forms storage-stable dispersions if the molar ratio of component A to component B is in the range from 2:1 to 1:3, the difference between the average chain length of the long-chain hydrocarbon radicals of components A and B is at most 2 carbon atoms and the hydrocarbon radicals of components A and B have on average in each case at most 0.5 double bonds per hydrocarbon radical. Such a composition can be produced by reacting a fatty acid, a Cdiol or Cpolyol, and a tertiary alkanolamine or a diamine having a tertiary and primary amino group in a suitable molar ratio with the removal of water and subsequent alkylation or protonation.
