摘要：Organopolysiloxanes that have betaine groups and are of the general formula##STR1## in which R.sup.1 can represent the same or different groups in the moleculeand 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 R.sup.1 radicals aremethyl radicals,< P>< P>R.sup.2 may be the same as R.sup.1, with the proviso that atleast one R.sup.2 radical represents the ##STR2## in which R.sup.3 and R.sup.4 are

different, one radical representing a hydroxyl group, and the other the ##STR3## in whichR.sup.5 and R.sup.6 are the same or different and represent an alkyl radical with 1 to 4carbon 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.
