摘要:
The present disclosure relates to a cosmetic composition for the treatment of keratinous fibers, such as the hair, comprising at least one polysaccharide chosen from lambda-carrageenans and at least one non-ionic surface-active agent chosen from alkylpolyglucosides, wherein the at least one polysaccharide is present in an amount ranging from 0.1 to 30% by weight of the total weight of the composition. The present disclosure also relates to a cosmetic method for treating keratin fibers and a cosmetic method for fixing and caring for the fibers.
摘要:
The present invention relates to a composition for washing keratinous substances, preferably keratinous fibers, comprising, in a cosmetically acceptable aqueous medium, at least one anionic or nonionic, amphiphilic linear block copolymer comprising at least one hydrophobic block and at least one hydrophilic block, with the exception of block copolymers of ethylene oxide and of propylene oxide, block copolymers comprising urethane units and block copolymers comprising siloxane units, at least one nonvolatile silicone, and at least one anionic surface-active agent in combination with at least one nonionic and/or amphoteric surface-active agent, and to the use of such a composition for washing keratinous substances.
摘要:
The invention relates to novel cosmetic compositions comprising, in a cosmetically acceptable medium, at least one fructan, at least one polysaccharide and at least one beneficial agent, a combination which gives the cosmetic compositions a velvety-smooth texture. Said composition can be easily rinsed off. Hair treated with said composition feels soft and contains no residue. The compositions are particularly suitable for washing and/or conditioning keratinous matter, such as the hair and skin.
