Cosmetic composition comprising a polyglycerolated silicone elastomer
The invention relates to a cosmetic composition comprising a polyglycerolated silicone elastomer for application onto keratinous materials, especially the skin or the lips, for purposes of care or makeup. In addition to at least one polyglycerolated silicone elastomer in a cosmetically suitable medium, the composition also contains at least one ingredient chosen from each of the following: an emulsifying elastomer different from the polyglycerolated silicone elastomer; a film forming polymer; a water-soluble humectant; a coated pigment; a structuring agent; a photoprotective system capable of screening out UV radiation; a nonemulsifying spherical silicone elastomer; a fiber; a noncross-linked surfactant; a hydrocarbyl-functional siloxane; a low molecular weight phenyl-substituted siloxane; and a cosmetically-suitable active ingredient. The noncross-linked surfactant must not be chosen from the polyglycerolated noncross-linked silicone surfactant(s).

The invention relates to cosmetic compositions, and in particular hair styling gels, containing in a cosmetically acceptable carrier at least one of each of the following: a fixing film-forming polymer, a thickening agent and a co-thickening agent. The film-forming polymer is chosen from branched block copolymers comprising, as principal monomers, at least one C1–C20 alkyl acrylate and/or at least one N-mono- or N,N-di(C2–C12 alkyl)(meth)acrylamide, and acrylic acid and/or methacrylic acid. The thickening agent is chosen from homopolymers and copolymers based on (meth)acrylic acid, which are cross-linked or noncross-linked. The co-thickening agent is chosen from noncellulosic thickening polymers different from the thickening agent(s).
