Film-forming cosmetic composition

摘要

Composition capable of forming a film having a higher cold water resistance than warm water resistance comprises a film-forming polymer (I) and a thermal transition agent (II) which undergoes a change of state at a temperature Tt between 25 and 80 degrees C and is insoluble in water at temperatures below Tt. New composition comprises a film-forming polymer (I) and a thermal transition agent (II) in a physiologically acceptable medium, where: (II) undergoes a change of state at a temperature Tt between 25 and 80 degrees C and is insoluble in water at temperatures below Tt; and (I) and (II) are present in amounts such that the composition is capable of forming a film at the temperature of keratinic materials, the film having a warm water resistance (Rw) of no more than 15 minutes for water at 40 degrees C and a cold water resistance (Rc) for water at 20 degrees C such that Rc - Rw is at least 8 minutes.
