Claims
- 1. 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%.
- 2. A wetting agent according to claim 1, wherein, in the nonionic surfactant of the general formula (4), R.sub.4 is hydrogen or C.sub.1 -to C.sub.4 alkyl and m.sub.3 is 1.
- 3. A wetting agent according to claim 1, wherein the hydrotropic agent in component (b) is an alkyl sulfate 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.
- 4. A wetting agent according to claim 1, wherein R.sub.8 is an aliphatic branched radical of 4 to 12 carbon atoms.
- 5. A wetting agent according to claim 1, wherein R.sub.8 is an aliphatic branched radical of 4 to 8 carbon atoms.
- 6. A wetting agent according to claim 1, which contains, relative to the agent,
- (a) 15 to 60% by weight of component (a),
- (b) 2 to 10% by weight of component (b),
- (c) 0 to 4% by weight of component (c) and
- water to add up to 100%.
