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.
Claims6
An aqueous storable wetting agent which is low-foaming in application consisting essentially of
- (a) 10 to 80% by weight of a nonionic surfactant of the general formula ##STR8## in which R.sub.2 is C.sub.9 -to C.sub.14 alkyl, R.sub.4 is hydrogen or C.sub.1 -to C.sub.4 alkyl, one of the radicals Y.sub.5 and Y.sub.6 is hydrogen and the other is ethyl, n.sub.3 is an integer from 4 to 8 and m.sub.3 is an integer from 1 to 3;
- (b) 1 to 10% by weight of a hydrotropic agent selected from the group consisting of aromatic alcohols of the formula ##STR9## in which X is --(CH.sub.2).sub.1-6 --, --CH.dbd.CH--CH.sub.2 -- or --O--(CH.sub.2).sub.2-6 -- and R.sub.5, R.sub.6 and R.sub.7, independently of one another, are hydrogen, hydroxyl, halogen or C.sub.1 -C.sub.6 alkoxy;
- and alkyl sulfates of the formula
- R.sub.8 O--SO.sub.3 X, (5)
- in which R.sub.8 is an aliphatic, saturated, branched or straight-chain radical of 4 to 24 carbon atoms and X is hydrogen, an alkali metal or ammonium;
- (c) 0 to 4% by weight of an nonpolar organic solvent;
- and
- (d) water to add up 100%.
