摘要

A cosmetic composition comprising at least one continuous liquid fatty phase containing at least one hydrocarbon-based oil and structured with at least one polymer chosen from polyurethanes, poliyurethaneureas, and polyureas, said at least one polymer being soluble or dispersible in said at least one hydrocarbon-based oil, and wherein said at least one polymer comprises in the chain thereof and/or grafted thereto: at least two groups chosen from urethane groups and urea groups, and at least one hydrocarbon-based unit chosen from hydrocarbon blocks and grafts, and from blocks and grafts of hydrocarbon-based, long-chain aliphatic polyesters.
