Abstract: Disclosed herein is a nail varnish composition comprising, in a cosmetically acceptable medium, at least one film-forming polymer, wherein the varnish composition is capable of forming a film having a rate of mass loss of less than 0.5 mg/minute when the film is subjected to abrasion produced with the Taber abrasimeter at 23° C., as well as a method for making up and/or non-therapeutic care of the nails comprising applying to the nails the composition.

Abstract: Linear block ethylenic copolymer comprising: at least two blocks with different glass transition temperatures (Tg); at least one of these blocks having a glass transition temperature of greater than or equal to 20° C.; said polymer also having mechanical parameters that satisfy at least one of the following three conditions: a Young's modulus E such that: 500 MPa?E?2000 MPa; an ultimate strain ?r such that: 5%??r?50%; an ultimate strain energy wr such that: 0.1×105 J/m3<wr<150×105 J/m3. Cosmetic composition comprising said polymer. The copolymer makes it possible to improve the styling power and the hold of a hair lacquer, to increase the adhesion and the wear strength of a nail varnish and to improve the staying power of a makeup composition without the compositions being tacky.

Abstract: The present disclosure relates to a nail varnish composition comprising at least one film-forming gradient copolymer exhibiting a mass polydispersity index (PI) of less than or equal to 2.5, the said composition being capable of forming a film exhibiting a rate of loss of weight of less than 1 mg/minute when the film is subjected to abrasion produced with the Taber abrasion tester at 23° C.

Abstract: 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.

Abstract: 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.
