The subject of the present invention relates to a composition for dyeing keratin fibers, comprising: a) one or more copolymer(s) derived from the polymerization of at least one monomer of crotonic acid or crotonic acid derivative and of at least one vinyl ester monomer, b) at least one oil-in-water emulsion having a particle size D 50 of less than 350 nm and which comprises: a silicone mixture comprising (i) at least one polydialkylsiloxane comprising trialkylsilyl end groups, having a viscosity at 25° C. ranging from 40 000 to 100 000 mPa·s and (ii) at least one aminosilicone having a viscosity at 25° C. ranging from 1000 to 15 000 mPa·s and an amine number ranging from 2 to 10 mg of KOH per gram of aminosilicone; a surfactant mixture comprising one or more nonionic surfactants, said mixture having an HLB ranging from 10 to 16, and water and c) at least one pigment.

Dye composition based on copolymers derived from the polymerization of at least one crotonic acid monomer or crotonic acid derivative and on silicone

The present invention relates to a composition for dyeing keratin fibers, comprising at least (i) one or more copolymers derived from the polymerization of at least one crotonic acid monomer or crotonic acid derivative and of at least two different vinyl ester monomers, (ii) one or more thickening polymers bearing (meth)acrylic acid unit(s), and (iii) one or more pigments. The invention also relates to a dyeing process in which said composition is applied to keratin fibers, the operation optionally being followed by drying. The composition makes it possible to obtain temporary dyeing having the advantage of forming a transfer-resistant deposit, leaving the treated fibers individualized, with an improved cosmetic feel.

Mascara containing film-forming polymers

The invention relates to a application system for coating, in particular, for making up, keratin fibers, having a reservoir containing a composition for coating, in particular, for making up keratin fibers, in particular, the eyelashes, a removable closure means designed to close the reservoir and an applicator member for applying the composition to the fibers, wherein the coating composition has an aqueous medium and a film-forming polyurethane in the form of solid particles dispersed in the aqueous medium, the composition having a viscosity, measured at 25&deg; C., at a shear rate of 200 s , ranging from 5 Pa&middot;s to 18 Pa&middot;s, and wherein the composition is free of wax.

Mascara product comprising a polyurethane

A composition for topical application comprising, in a cosmetically, dermatologically, hygienically or pharmaceutically acceptable support, at least one fatty phase and at least one lipophilic polymer, wherein the lipophilic polymer is a tert-butylstyrene/C,-C,alkyl methacrylate/C,-C,alkyl acrylate copolymer. The composition makes it possible to obtain a film which has very good staying power and good transfer-resistance properties. The film obtained is particularly resistant to water, to rubbing, for example with the fingers or against clothing, to perspiration and to sebum.

Cosmetic composition comprising a styrene/acrylate copolymer and a fatty phase

A cosmetic composition for coating keratin fibers, in particular the eyelashes. The composition can provide a waterproof coating that curls the keratin fibers. The composition comprises at least one lamellar filler, and an aqueous phase dispersed in a liquid fatty phase containing at least one volatile organic solvent. The aqueous phase contains a polymer system comprising at least one film-forming polymer which is dispersed in the aqueous phase in the form of solid particles.
