COMPOSITION A BASE D'HUILE SILICONEE STRUCTUREE SOUS FORME RIGIDE, NOTAMMENT POUR UNE UTILISATION COSMETIQUE

Composition (A) comprises a fatty liquid phase comprising a silicone oil structured by a gelling agent constituted by a polymer (homopolymer or copolymer) of average molecular weight 500-500000, comprising at least a unit comprising at least a polyorganosiloxane group constituted of 1-1000 organosiloxane units in the chain of the unit or in the form of graft, and at least two groups capable of establishing hydrogen interactions comprising ester, amide, sulfonamide carbamate, thiocarbamate, urea, thiourea, oxamido, guanidino and/or biguanidino groups. Composition (A) comprises a fatty liquid phase comprising a silicone oil structured by a gelling agent constituted by a polymer (homopolymer or copolymer) of average molecular weight of 500-500000, comprising at least a unit comprising at least a polyorganosiloxane group constituted of 1-1000 organosiloxane units in the chain of the unit or in the form of graft, and at least two groups capable of establishing hydrogen interactions comprising ester, amide, sulfonamide carbamate, thiocarbamate, urea, thiourea, oxamido, guanidino and/or biguanidino groups. Provided that at least one of the groups is different from an ester group, where the polymer is solid at room temperature and soluble in fatty liquid phase at 25-250[deg] C, the fatty liquid phase is totally or partially constituted of volatile oil having a flash point >= 40[deg] C and higher than the softening temperature of gelling polymer, and the fatty liquid phase and the polymer forming a medium. Independent claims are included for: (1) a structured solid composition for making up the skin, lips and/or integuments, comprising (A), which is in the form of a solid and pigment, provided that (A) comprises at least 10 mass.% of a non-volatile oil and/or pasty or viscous product; (2) a stick for makeup of skin, lips and/or integuments, preferably lips, comprising (A); (3) a cosmetic process for caring, making up or treating of human keratinous materials, comprising applying cosmetic composition on keratinous material; and (4) a cosmetic process for limiting the migration of the cosmetic composition, comprising structuring (A).
