摘要:
The invention relates to cosmetic compositions comprising, in a cosmetically acceptable medium, at least one conditioner chosen from poly-&agr;-olefins, fluoro oils, fluoro waxes, fluoro gums, carboxylic acid esters, cationic polymers, silicones that are insoluble in the medium, mineral, plant or animal oils and at least one polyoxyalkylenated aminosilicone of (AB)n type, A being a polysiloxane block and B being a polyoxyalkylenated block containing at least one amine group. This combination gives considerably better cosmetic properties (smoothness, softness) than the properties obtained with one or other of the constituents used alone. These compositions are used to wash and/or condition the hair.
摘要:
The invention relates to novel detergent cosmetic compositions comprising, in a cosmetically acceptable medium, at least one anionic surfactant chosen from 2-hydroxyalkyl ether carboxylic acid and salts thereof and at least one non-cellulosic cationic polymer the cationic charge density of which is greater than or equal to 2 meq/g. The invention also relates to processes for washing and/or treating keratin substances with the novel detergent cosmetic compositions.
摘要:
Detergent compositions containing, in a cosmetically acceptable medium, a washing base, at least one water-insoluble carboxylic acid ester and at least one amphoteric polymer comprising at least one monomeric unit chosen from (meth)acrylate and (meth)acrylamide types containing at least one fatty chain, the fatty chain containing from 8 to 30 carbon atoms. These compositions can have improved cosmetic properties, in particular in terms of smoothing the hair. The composition can be used for cleansing, caring for and styling the hair.
摘要:
A cosmetic composition containing, in a cosmetically acceptable medium, at least one antidandruff agent and at least one amphoteric polymer containing at least one monomeric unit chosen from (meth)acrylate and (meth)acrylamide types containing at least one fatty chain, the fatty chain containing from 8 to 30 carbon atoms. This combination makes it possible to improve the deposition of the antidandruff agent. These compositions are used for washing and/or conditioning keratin substances such as the hair or the skin.
