摘要:
An aqueous cosmetic composition for fixing hair is an aqueous particulate dispersion. The dispersion includes particles of a film-forming polymer containing carboxylic acid functions neutralized to a degree of neutralization from between 10 and 80 percent using a non-volatile monobasic agent. The particles have an average diameter of between 10 and 300 nm. The aqueous dispersion also includes at least one plasticizing agent. The composition may be used as an aerosol lacquer, a fixing or setting lotion or a styling mousse.
摘要:
The present invention relates to a cosmetic or pharmaceutical composition comprising an aqueous dispersion of polymers, in particular as film-forming agent. The said aqueous dispersions are obtained by radical polymerization of radical monomer, within and/or partially at the surface, of preexisting particles of at least one polymer chosen from the group consisting of polyurethanes and/or polyureas.

The present application relates to a cosmetic composition, in particular a care or make-up composition to be applied to the skin and/or to the eyelashes, which comprises at least one fatty substance and at least one aqueous polymer dispersion consisting of particles resulting from the polymerization of a radical monomer in the interior and/or partially at the surface of already existing polymer particles of polyester type.
摘要:
Use in association, as oil thickners, in a cosmetic composition comprising an oily phase, of at least one first copolymer including patterns derived from at least one lipophilic monomer and patters derived from at least one hydrophilic monomer, comprising at least one carboxylic acid or sulphonic grouping, and of at least one second copolymer including patterns derived from at least one lipophilic monomer and patterns derived from at least one hydrophilic monomer comprising at least one amine, amide, alcohol or ether grouping. Said first and second copolymers have a molecular weight of not less than approximately 100 000. The association enables thickened composition to be obtained, the texture, look and feel of which correspond to a cosmetic use.
