Abstract: The invention relates to a cosmetic makeup composition and/or care composition for the skin, comprising a dispersion, in a cosmetically acceptable medium, of particles comprising an at least partially internal supple phase comprising at least one supple polymer having a glass transition temperature of less than or equal to 60° C., and an at least partially external rigid phase which is an amorphous material having a glass transition temperature of greater than 60° C., the supple polymer being at least partially attached by chemical grafting onto the rigid phase.

Abstract: Cosmetic composition comprising a particle dispersion The invention relates to a cosmetic makeup composition and/or care composition for the skin of the lips, comprising a dispersion of particles, in a cosmetically acceptable medium, the particles comprising an at least external supple phase comprising at least one supple polymer having at least one glass transition temperature of less than or equal to 60° C., and an at least internal rigid phase which is a functionalized crystalline or semicrystalline material having a first-order phase transition, of melting or of combustion, of greater than 40° C., the supple polymer being at least partially attached by chemical grafting onto the rigid phase. The invention also relates to the use of such a particle dispersion to improve the comfort and staying power of cosmetic compositions.

Abstract: A composition useful as a tightening agent for decreasing or removing signs of aging, particularly for reducing or removing wrinkles and/or fine lines or to smooth out human skin. This composition comprises at least one grafted silicone polymer which itself comprises a polysiloxane portion and a portion composed of a non-silicone organic chain, one of the two portions constitutes the main chain of the polymer and the other is grafted to said main chain. Processes for the cosmetic treatment of aged skin, in particular wrinkled skin, comprising the application of an effective amount of the composition as defined above to achieve improvement in the appearance of rough, damaged or aged skin, or achieve softening the wrinkle by a tightening effect.

Abstract: This invention relates to the use of colloidal silicic acid as a cushioning agent in a composition including at least one film-forming material and at least one organic or aqueous solvent.
