C. and at least one cationic amphiphilic lipid, and its uses in cosmetics or in dermopharmaceuticals.

Abstract: The invention relates to new cosmetic compositions comprising, in an aqueous medium, at least one lipid ceramide compound and at least one peptide having at least one fatty chain. The invention also relates to an aqueous dispersion comprising a peptide having at least one fatty chain and at least one lipid ceramide compound.

Abstract: A detergent hair composition of the type including, in a cosmetically acceptable medium, a washing base and at least one cationic polymer, and additionally comprising at least one water-soluble or water-dispersible silicone compound including a silicone main chain onto which at least one hydrocarbon group of anionic nature is grafted.This composition may be applied to clean, care and style hair and gives an improved styling effect.

Abstract: The present invention relates to a composition for the treatment of keratinous material, in particular human hair, comprising, in a cosmetically or dermatologically acceptable medium, at least one grafted silicone polymer, containing a polysiloxane skeleton grafted with non-silicone organic monomers and at least one hydrocarbon which is liquid at room temperature, the hydrocarbon chain of which has from 11 to 26 linear or branched, cyclic or acyclic carbon atoms, as well as its applications.The compositions according to the invention are used in particular as rinse-out products or as leave-in products, in particular for the washing, care and conditioning of the hair, for maintaining the hairstyle or for shaping the hairstyle.

Abstract: A cosmetic or dermatological composition for treating keratinous material, particularly human hair, including a cosmetically or dermatologically acceptable medium containing at least one anionic, amphoteric or non-ionic silicone-grafted polymer with a polysiloxane backbone grafted by non-silicone organic monomers, and at least one amphoteric polymer, wherein the ratio of the amphoteric polymer to the silicone-grafted polymer is 0.25-15. Such compositions are particularly suitable for use as rinsable or non-rinsable products for washing and conditioning hair, hair setting or hair styling.

Abstract: A method for strengthening of the mechanical and/or cosmetic properties of keratinous superficial body growths such as the hair, the eyelashes and the nails, by applying certain bioflavonoids, in particular citrus bioflavonoids, as treatment agents to the keratinous superficial body growths. Also, stable compositions containing bioflavonoids and a method for protecting the keratin of superficial body growths from damage by environmental agents.
