Abstract
Abstract A fabric softener which contains as fabric-softening agent from 1 to 35% by weight of a condensation product obtained from about 1 to 1.5 moles of a fatty acid or a fatty acid ester of the formula I r--co.sub.2 x (i), in which R represent an aliphatic radical having from about 11 to 21 carbon atoms, and X stands for hydrogen, methyl or ethyl, with 1 mole of an alkyl-propylene-diaminoxalkylate of the formula II ##STR1## in which R 1 represents an aliphatic radical having from 12 to 22 carbon atoms, and R 2 stands for hydrogen or methyl, and x, y and z stand for 0 or 1, the sum of x, y and z being from 1 to 2.
