Abstract
An aqueous, storable wetting agent which is low-foaming in application and contains a nonionic surfactant selected from the group of the partially end group blocked alkoxylated fatty alcohols is described, which contains (a) 10 to 80% by weight of a nonionic surfactant of the general formula ##STR1## in which R is an aliphatic radical of at least 8 carbon atoms, R.sub.1 is hydrogen, C.sub.1 -to C.sub.8 alkyl, a cycloaliphatic radical of at least 5 carbons atoms, phenyl(lower)alkyl or styryl, "alkylene" is an alkylene radical of 2 to 4 carbon atoms and p is a number from 2 to 24 and (b) 1 to 10% by weight of a hydrotropic agent. The novel wetting agent is used in the treatment of textiles, in particular in the pre-treatment.
