1. Hydrophobizing dispersion gel comprising relative to a total quantity of 100 wt. % the components:
(A) 0.1 wt. %-less than 50 wt. % alkyltrialkoxysilane, (B) 0.1 wt. %-1.0 wt. % branched polyacrylic acid, (C) 0.5 wt. %-2.0 wt. % trialkyl-amine-N-oxide, (D) 3.0 wt. %-10 wt. % non-ionic tenside and (E) 10 wt. %-80 wt. % water, wherein the trialkyl-amine-N-oxide (C) is an amine oxide having the general formula I, wherein R1, R2, and R3 are each independently of one another the same or different and selected from C1-C6 alkyl groups which are unsubstituted or substituted with one or more hydroxyl groups, where optionally two of the residues R1, R2, and R3 together form a saturated ring which optionally contains another oxygen atoms and where the residues R1, R2, and R3 independently of one another are optionally substituted by an —N+(R1, R2)—O−group, and the non-ionic tenside (D) is either a) a tenside having the general formula (lla) or b) a tenside having the general formula (llb) or c) a tenside having the general formula (llc) or d) a fatty acid-bis-(polyoxyalkylene)-amide having the general formula (lld), wherein the residues R1-R4 of the non-ionic tenside (D) each have the following meaning: R1 are alkyl or alkenyl residues having 6 to 22 carbon atoms as well as mixtures of these residues, R2 is hydrogen or a methyl group, R3 is hydrogen or alkyl groups having 1 to 6 carbon atoms, R4 are alkyl groups with 1 to 6 carbon atoms optionally bound via hetero atoms, preferably oxygen, and x and y are numbers from 1 to 25. |
