Zusammenfassung:Organopolysiloxanes that have betaine groups and are of the general formula I in which R1 can represent the same or different groups in the molecule and may be an alkyl radical with 1 to 18 carbon atoms, an aryl radical or a polyoxyalkylene radical with the proviso that at least 70% of the R1 radicals are methyl radicals, R2 may be the same as R1, with the proviso that at least one R2 radical represents the in which R3 and R4 are different, one radical representing a hydroxyl group, and the other the in which R5 and R6 are the same or different and represent an alkyl radical with 1 to 4 carbon atoms or a benzyl radical, and n=1, 2, or 3, x has a value of 0 to 200, and y has a value of 1 to 50, as well as processes for their synthesis and their use in cosmetic preparations.
