Abstract

A nonionic detergent mixture containing PA1 a) an ether corresponding to formula (I): EQU R.sup.1 O(CH.sub.2 CH.sub.2 O).sub.m R.sup.2 (I) PA1 in which R.sup.1 is an aliphatic linear alkyl or alkenyl radical containing 12 to 18 carbon atoms, R.sup.2 is an alkyl radical containing 1 to 4 carbon atoms or a benzyl radical and m is a number of 5 to 15, and PA1 b1) an ether selected from the group consisting of an ether corresponding to formula (II): ##STR1## in which R.sup.3 is an aliphatic, linear or branched alkyl radical containing 8 to 10 carbon atoms, R.sup.4 is an alkyl radical containing 1 to 4 carbon atoms or a benzyl radical, p is a number of 2 to 3 and q is a number of 8 to 15 and PA1 b2) an ether corresponding to formula (III): ##STR2## in which R.sup.5 is an aliphatic, linear alkyl radical containing 12 to 14 carbon atoms, R.sup.6 is an alkyl radical containing 1 to 4 carbon atoms or a benzyl radical, x is a number of 0.5 to 2 and y is a number of 5 to 10.
