Abstract
Use of a composition containing at least one hydrophobic film-forming polymer and at least one thermal transition agent, in a physiologically acceptable medium, to obtain a film, wherein the composition is applied to a keratinous material, and the film may be removable with hot water. The at least one thermal transition agent being capable of undergoing a transition at a transition temperature Tt chosen within a temperature range of from 25° C. to 80° C., and being not water soluble in water maintained at a temperature below the transition temperature Tt, wherein the at least one hydrophobic film-forming polymer and at least one thermal transition agent are the same or different. The invention also relates to a composition containing, in a physiologically acceptable medium, at least 5% by weight, relative to the total weight of the composition, of at least one first hydrophobic film-forming polymer, and at least one thermal transition agent which is capable of undergoing a change of state within a transition temperature range of from 25° C. to 80° C., and being not water soluble in water maintained at a temperature below the transition temperature. The composition makes it possible to obtain a film which may be resistant to cold water and removable with hot water.
