Abstract:
1. An organopolysiloxane copolymer comprising, on average, at least one polyester group bonded to a siloxane via a spacer and, on average, at least one hydrophilic group bonded to the siloxane via a spacer, of the general formula (I): in which each R each R in which —A— is a divalent alkyleneoxy group having 3 to 24 carbon atoms, which is optionally branched and/or can contain double bonds, and/or is a divalent polyoxyalkylene group of the general average formula in which q=1 to 100, r=0 to 100, s=0 to 100, R R in which t is an integer in the range from 2 to 5, and [—(O═C)—S—O—] is a radical of 12-hydroxystearic acid or of ricinoleic acid, —B— acts as a spacer between siloxane backbone and R R -R R a has a value from 1 to 1000, and b has a value from 0 to 10, with the proviso that, on statistical average, at least in each case one radical R
