Abstract

Quaternary N-alkyl-N,N'-,N'-polyoxyalkyl-.alpha.,.omega.-diamino-alkylene fatty acid esters of the formula (1) ##STR1## in which R.sub.1 is C.sub.8 -C.sub.30, preferably C.sub.16 -C.sub.18 -alkyl, or C.sub.8 -C.sub.30, preferably C.sub.16 -C.sub.18 -alkenyl, PA0 R.sub.2 is C.sub.1 -C.sub.4 -alkyl, preferably methyl, PA0 R.sub.3 is C.sub.7 -C.sub.29, preferably C.sub.15 -C.sub.17 -alkyl or C.sub.7 -C.sub.29, preferably C.sub.15 -C.sub.17 -alkenyl, PA0 x and y each are hydrogen or methyl with the proviso that x and y are not simultaneously methyl, PA0 a is 0, 1 or 2, PA0 n is an integer of from 1 to 11, preferably 1, PA0 m is 1 or 2, PA0 p is an integer or from 1 to 5, preferably 3, and PA0 A is an anion, preferably a halogen, methosulfate or methophosphate ion. These compounds are prepared by esterifying the basis oxalkylated alkylene diamines with fatty acids and subsequent quaternization. They are used as softeners.
