Abstract
The invention relates to polysiloxane block copolymers of the formula A[LB(S)Q]m, where A is a polysiloxane block, L is a divalent organic linker, B is a polymer block composed of radically polymerizable monomers, S is a sulfur atom and Q is a monovalent organic radical and m is an integer from 1 to 50, to a method for their production, and to their use in cosmetics or personal care.
