Abstract: The present invention relates to a composition for washing and conditioning keratin materials, comprising, in a physiologically acceptable medium: from 3% to 50% by weight, relative to the total weight of the composition, of one or more anionic surfactants, one or more C10-C30 liquid alcohols chosen from branched and/or unsaturated C10-C30 alcohols, and one or more nonionic associative polymers. The invention also relates to the use of the said composition for washing and conditioning keratin materials, and to a process for washing and conditioning keratin materials using it.

Abstract: The present invention relates to a composition for washing and conditioning keratin materials, comprising, in a physiologically acceptable medium: one or more anionic surfactants, one or more liquid fatty alcohols, and one or more ethers of a fatty alcohol and of an oxyethylenated polyol of formula (I). The invention also relates to the use of the said composition for washing and conditioning keratin materials, and to a process for washing and conditioning keratin materials using it.

Abstract: The present patent application relates to cosmetic compositions comprising cationic compounds of quaternary ammonium esters derived from 2-[2-(diethylamino)ethoxy]ethanol type, to the use of these cationic compounds, in particular as conditioning agent, to a cosmetic treatment method, in particular a hair treatment method, employing them and to the novel cationic compounds.

Abstract: Disclosed herein is a method for treating keratinous fibers comprising coating the keratinous fibers with a reducing agent, rinsing the keratinous fibers, coating the keratinous fibers with a cosmetic composition comprising at least one non crystalline or semi-crystalline fixing polymer, and/or at least one cerid, and/or at least one sterid, raising the temperature of the keratinous fibers, and coating the keratinous fibers with an oxidizing agent. This method may make it possible to achieve a hair style with an excellent hold which is durable over time.

Abstract: A cosmetic composition. In a cosmetically acceptable medium: one or more vinylformamide/vinylformamine copolymers, and one or more thickening polymers different from the vinylformamide/vinylformamine copolymers. Can be used for hair styling, and can make it possible to obtain a particularly lasting retention of the hair style and hair conditioning properties.

Abstract: A cosmetic composition containing in a cosmetically acceptable aqueous medium: one or more non-silicone fatty substances, one or more surfactants, one or more vinylformamide/vinylamine copolymers, and one or more silicones. Can be used for the styling of the hair and can make possible to obtain a lasting hold of the hairstyle and also hair conditioning properties.

Abstract: The present invention relates to multiphasic particles (MPPs), their design, composition, and use. The present invention also relates to products, and in particular, cosmetics, personal care products, and topical or dermatological products, which may be produced using MPPs.

Abstract: Disclosed herein is a method for treating keratinous fibers comprising coating the keratinous fibers with a reducing agent, rinsing the keratinous fibers, coating the keratinous fibers with a cosmetic composition comprising at least one non crystalline or semi-crystalline fixing polymer, at least one cerid, and/or at least one sterid, raising the temperature of the keratinous fibers, and coating the keratinous fibers with an oxidizing agent. This method may make it possible to achieve a hair style with an excellent hold which is durable over time.

Abstract: The present disclosure relates to a cosmetic composition comprising, in a cosmetically acceptable medium, at least one compound having an opened or a closed cage-like structure, wherein the at least one compound comprises at least 4 atoms of an element chosen from columns 3 to 13 of the Periodic Table, and at least 4 oxygen atoms, wherein the atoms of the element are linked to oxygen atoms and at least one substituent, which are the same or different.

Abstract: Described herein is a hair styling composition comprising, in a physiologically acceptable liquid medium: at least one hydrophilic polymeric high porosity material, and at least one fixing polymer, with the proviso that the at least one hydrophilic polymeric high porosity material is not a silicone polymer or an alkyl polymethacrylate polymer (PMMA). The compositions disclosed herein make it possible to obtain a more strongly fixed and a longer lasting hair style.

Abstract: The present disclosure relates to a cosmetic composition comprising, in a cosmetically acceptable medium, at least one diamantoid comprising at least two adamantane units. The present disclosure further relates to a method for treating keratin materials, as well as a method for improving the mechanical properties of some materials that are used in cosmetics.

Abstract: Disclosed herein are a cosmetic composition for the cosmetic treatment of keratin fibers, which comprises, in a cosmetically acceptable medium, at least one nanoobject of elongate form made of at least one crosslinked synthetic polymer, and methods of cosmetic treatment of keratin fibers comprising applying this composition to the keratin fibers to impart body to the hairstyle.

Abstract: The present disclosure relates to a cosmetic composition, especially a hair composition, comprising, in a cosmetically acceptable medium, at least one cosmetically active compound and a gel comprising at least one crosslinked network of crosslinked polymer particles. The disclosure is also directed towards a method for fixing and/or holding a hairstyle using the composition, and also to the method of manufacturing a gel cosmetic formulation for holding and/or fixing the hairstyle.
