Abstract
A composition containing, at least one film-forming polymer and at least one thermal transition agent which undergoes a change of state at a transition temperature Tt chosen within the range from 25° C. to 80° C., the at least one thermal transition agent being not water soluble in water maintained at a temperature below the transition temperature Tt, the at least one film-forming polymer and the at least one thermal transition agent are present in an amount which is sufficient so that the composition is capable of forming a film, at the temperature of a keratinous material, wherein the film has a water uptake (Rc) for hot water maintained at 40° C. of at least 15%, and a water uptake (Rf) for cold water maintained at 20° C. wherein Rc−Rf≧3%, and wherein the at least one film-forming polymer and the at least one thermal transition agent are the same or different. The invention also relates to a cosmetic care or make-up process for a keratinous material. The composition makes it possible to obtain a film which may be resistant to cold water and removable with hot water.
