An organopolysiloxane copolymer containing on average at least one polyester group bonded to the siloxane via a spacer and on average at least one hydrophilic group of given formula bonded to the siloxane via a spacer is new. An organopolysiloxane copolymer containing on average at least one polyester group bonded to the siloxane via a spacer and on average at least one hydrophilic group bonded to the siloxane via a spacer, the hydrophilic group having the formula (I): R1 = 1-30C alkyl or phenyl, R2 = R1, A-R3 or -B-R4, A = divalent 3-24c alkleneoxy group, which can be optionally branched and/or contains double bonds and/or a divalent polyoxyalkylene group of average formula (II):q = 1-100, r = 0-100, s = 0-100, R5 = 1-24C divalent alkyleneoxy, which can be optionally branched and/or contains double bonds, R3 = polyester of formula (III): t = 1-10, (-(O = C)-S-O-) = a fragment of the corresponding hydroxycarboxylic acid HO-(O=C)-S-OH, S = optionally branched and/or double bond containing 5-30C alkylene, with the proviso that the carboxyl group (HO-C(O)-) and OH group (-OH) are separated by at least 5 C atoms, B = a spacer between the siloxane residue and R4 and is of know type, R4 = a hydrophilic residue of average formula (IV):q = 1-100, r = 0-100, s = 0-100, R6 = alkylene or 1-24C alkyleneoxy, which can be optionally branched and/or contains double bonds, R7 = H, or 1-20C acyl, R4 = polyhydroxyorganyl, especially glycerol, polyglycerol, sugar or sugar derivative, polyvinylalcohol, carboxylate, sulfate, or phosphate, ammonium, or amphoteric betain or amphoglycinate, a = 1-1000, b = 0-10, with the proviso that on statistical average at least one R2 = -A-R3 and R2 = -A-R3, A = divalent polyoxyalkylene of formula (II) above. Independent claims are included for: (1) a process for preparation of compounds of formula (I) in which the polyester residue is obtained either by hydrosilation of double bond carrying polyesters on the polyhydrogensiloxane or by esterification of OH functional polysiloxanes with free carboxyl grou p carrying polyesters with addition of the hydrophilic residue by a known process to the polysiloxane; (2) dispersions and emulsions containing at least one compound of formula (I); (3) cosmetic W/O emulsions containing 0.5-4 wt.% on the total formulation of at least one compound of formula (I).
