The use in and for the preparation of both cosmetic and/or dermatological compositions comprising at least one amphoteric copolymer that is crosslinked and/or branched and derived, e.g., from a mixture comprising at least one monomer selected from acrylate, methacrylate, acrylamide, and methacrylamide monomers comprising at least one C -C fatty chain. Another subject of the invention is the application of the composition for the treatment of keratinous materials and in particular of the skin, hair, eyelashes, and nails.

Cosmetic and dermatological compositions comprising crosslinked and branched amphoteric copolymers and their use

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&deg; 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&deg; C., as well as the cosmetic or dermatological compositions employed.

Polyfluoroalkylthiopoly (ethylimidazolium) compounds, preparation

Cosmetic compositions for bleaching hair comprising at least one oxidizing agent selected from peroxygen compounds and at least one block and/or random linear polyoxyethylene/polyoxypropylene copolymer, the copolymer being anhydrous and, at room temperature, further being both liquid and soluble in water, and the composition being pulverulent and anhydrous. Bleaching powders that are fine, anhydrous, free-flowing, homogeneous, non-dusty, are perfectly dispersible in hydrogen peroxide and have improved cosmetic properties.
