Transfer-free composition structured in the stiff form by a polymer

Abstract

The invention relates to a physiologically acceptable, in particular cosmetic, composition comprising at least one liquid fatty phase comprising at least one volatile solvent, the liquid fatty phase being structured by at least one polymer with a weight-average molecular mass of less than or equal to 100 000, comprising a) a polymer backbone having hydrocarbonaceous repeat units provided with at least one heteroatom and b) optionally functionalized pendant and/or end fatty chains having from 6 to 120 carbon atoms which are bonded to these units, the liquid fatty phase and the polymer forming a physiologically acceptable medium. This composition is provided in particular in the form of a stick of lipstick, the application of which results in a notable glossy and transfer-free layer with good hold over time.

1 . A structured composition comprising at least one volatile solvent, the liquid fatty phase being structured by at least one polymer with a weight-average molecular mass of less than or equal to 100 000 comprising a) a polymer backbone having hydrocarbonaceous repeat units provided with at least one heteroatom and b) at least one optionally functionalized pendant and/or end fatty chanin having from 6 to 120 carbon atoms which is bonded to these hydrocarbonaceous units, the liquid fatty phase and the polymer forming a physiologically acceptable medium.
