摘要:
The invention relates to a care and/or make-up cosmetic composition comprising a liquid fatty phase comprising at least one silicone oil, structured with a gelling system comprising1) at least one polymer having a weight-average molecular mass ranging from 500 to 500 000, containing at least one moiety comprising: at least one polyorganosiloxane group consisting of 1 to 1 000 organosiloxane units in the chain of the moiety or in the form of a graft, and at least two groups capable of establishing hydrogen interactions, the polymer being solid at room temperature and soluble in the liquid fatty phase at a temperature of 25 to 250° C., and 2) at least one non-polymeric organogelling agent.
摘要:
A composition comprising at least one liquid fatty phase structured by at least one semi-crystalline polymer having a low melting point and an organic structure, wherein said polymer is solid at ambient temperature, has a melting temperature of less than 50° C., and comprises a) a polymer backbone and b) at least one crystallizable organic side chain and/or one crystallizable organic block that forms part of the polymer backbone of said polymer, wherein said polymer has a number-average molecular mass of greater than 2000, and wherein the liquid fatty phase and the polymer form a physiologically acceptable medium. This composition is provided in the form of a stick, for example, which deposits, on keratinous substances such as the lips, a glossy, nonsticky and covering film.
摘要:
The subject-matter of the present invention is the use, in and for the preparation of cosmetic or dermatological compositions, of a grafted copolymer, the skeleton (S) of which is composed of a hydrophilic copolymer, with a glass transition temperature Tg greater than 25° C., obtained by radical polymerization or by polycondensation, comprising, on the chain of the skeleton (S), at least one graft composed of a hydrophobic macromonomer (M) with a glass transition temperature T'g of less than 25° C., as well as the cosmetic or dermatological compositions employed.

The present invention relates to hair-care compositions comprising aqueous polymer dispersions as film-forming agent. These polymers are obtained by free-radical polymerization of a radical monomer in the interior and/or partially at the surface of already existing polymer particles of polyester type.
摘要:
The present invention is directed to a cosmetic composition comprising at least one neutralized ionic film-forming polymer, water and least one polar organic solvent which is at least partially water-miscible and of higher boiling point than the boiling point of water, wherein the film-forming polymer is insoluble in water and is soluble in the organic solvent when it is in a non-neutralized state. In addition the neutralized film-forming polymer is soluble in the mixture of organic solvent and water and further wherein the mixture of neutralized polymer, organic solvent and water is a single phase, where the single phase is a homogeneous solution.
