Abstract

The present invention relates to copolymers which are formed from specific amounts of (a) ethylene and (b) monomer(s) selected from propylheptylacrylate and propylheptyl-methacrylate, and optionally at least one further monomer. Said copolymers are useful as oil soluble additives for cosmetic formulations and especially oil depositioning enhancers for rinse-off formulations.
