Abstract

Concentrated masterbatches of fabric softeners consisting substantially of PA0 (a) from 20 to 70, weight % of one or more compounds of the formulae I to III, ##STR1## in which R.sub.1 is alkyl or alkenyl having from 8 to 22, carbon atoms, R.sub.2 is alkyl having from 1 to 4 carbon atoms, R.sub.3 is methyl or hydrogen, x is a number of from 1 to 5 and A is an anion PA0 (b) from 20 to 60, weight % of a paraffin, a fatty alcohol, a fatty acid, a fatty acid-C.sub.1 -C.sub.13 -alkyl ester, each having from 8 to 22, carbon atoms, a polyethyleneglycol having a molecular weight of from 200 to 600, an alkyl ester having from 8 to 22, carbon atoms of a polyethyleneglycol having a molecular weight of from 200 to 600 or a polypropyleneglycol having a molecular weight of from 200 to 1,000 or mixtures thereof, PA0 (c) from 5 to 25 weight % of an amino-oxethylate of the formula ##STR2## in which R.sub.1 is alkyl or alkenyl having from 8 to 22, carbon atoms, x and y are hydrogen or methyl, with the proviso that x and y are not simultaneously methyl, n is an integer of from 2 to 40, preferably 10, p is a number of from zero to 1 and m is a number of from zero to 3, with the provisio that in case of…
