ABSTRACT:
The invention relates to a composition comprising, in a physiologically acceptable medium, at least one first semi-crystalline polymer having a melting point of greater than or equal to 30° C., and at least one second film-forming polymer capable of forming a hydrophobic film at room temperature. The composition makes it possible to obtain a film that is more resistant to removal by cold water than to removal by warm water. The composition can be applied to the making up and care of keratin materials.
