The present disclosure relates to a cosmetic composition comprising, in an aqueous medium, at least one film-forming polymer, at least one aqueous microdispersion of wax, and at least one water-soluble aromatic acid ester that is liquid at room temperature. The present disclosure also relates to the process for cosmetically treating keratinous materials, such as the skin, comprising applying said composition to keratinous materials. The composition is easy to apply on keratinous materials and forms a glossy and non-sticky film.

Film-forming cosmetic composition

The invention relates to a composition comprising, in a physiologically acceptable medium containing a fatty phase, a polymer with a weight-average molecular mass of less than 100 000 and in particular ranging from 1 000 to 30 000, comprising a) a polymer skeleton containing hydrocarbon-based repeating units containing at least one hetero atom, and optionally b) pendent fatty chains and/or terminal fatty chains, which may be functionalized, containing from 6 to 120 carbon atoms and being linked to these units, and fibres.

Cosmetic composition comprising a polymer and fibres

Cosmetic composition comprising a polymer blend The invention relates to a composition comprising, in a physiologically acceptable medium, at least a first polymer with a weight-average molecular mass of less than 100 000, comprising a) a polymer skeleton containing hydrocarbon-based repeating Units containing at least one hetero atom, and optionally b) at least one pendent fatty chain and/or at least one terminal fatty chain, which may be functionalized, containing from 6 to 120 carbon atoms and being linked to these hydrocarbon-based units, a dispersion of particles of a second film-forming polymer that is insoluble in said medium. Application to make-up and caring for keratin materials.

Cosmetic composition comprising a polymer blend

The invention relates to methods for the make-up to and care of a keratinous material comprising applying to a keratinous material a composition comprising an aqueous microdispersion of particles of at least one wax and an aqueous dispersion of particles of at least one film-forming polymer. The composition makes it possible to obtain a film which may be resistant to cold water and may be removed as make-up with hot water. The invention also relates to a mascara comprising an aqueous microdispersion of particles of at least one wax and an aqueous dispersion of particles of at least one film-forming polymer wherein the particles of at least one film-forming polymer have a mean particle size of at least 10 nm and further wherein the at least one film-forming polymer is not a coloring polymer and methods for application of the mascara.

The invention relates to the use of at least one polymer chosen from ethylenediamine/stearyl dimer tallate copolymer in a mascara for increasing the adhesion of and/or expressly loading make-up deposited on the eyelashes.

Use of at least one polyamide polymer in a mascara composition for increasing the adhesion of and/or expressly loading make-up deposited on eyelashes

A cosmetic or dermatological film-forming composition comprising a liquid fatty phase, including at least one volatile hydrocarbon oil, and a film-forming polymer in said liquid fatty phase, characterized in that it comprises at least one polyolefin wax resulting from the polymerization of alpha-olefins having at least 10 carbon atoms, said wax having a melting point ranging from 50 to 80&deg; C. The invention includes the use of such a composition, especially for producing a water-resistant film exhibiting good hold with regard to rubbing, to tears, to perspiration or to sebum.

Cosmetic composition comprising a film-forming polymer, a poly-alpha-olefin and a liquid fatty phase

A make-up cosmetic composition for the skin comprising, in a cosmetically acceptable aqueous medium, at least one film-forming polymer, at least one nonionic surfactant, and at least one pulverulent coloring matter, wherein said at least one nonionic surfactant is chosen from polyethylene glycol/polypropylene glycol/polyethylene glycol triblock polycondensates. The composition makes it possible to obtain a make-up for the skin having good covering power and which is tolerated by sensitive skins and/or eyes.

Make-up composition for the skin

A process for making up or caring for keratin fibers. A composition comprising at least one film-forming polymer in the form of particles in aqueous dispersion, wherein the at least one film-forming polymer is chosen from polyurethanes, and fibers is applied to the keratin fibers. A cosmetic composition comprising at least one film-forming polymer in the form of particles in aqueous dispersion, wherein the at least one film-forming polymer is chosen from polyurethanes, at least one wax, and fibers, can also be applied to the keratin fibers.

Cosmetic composition comprising fibers and a film forming polymer

Mascara containing film-forming polymers

The invention includes a composition for making up keratinous material, in the form of a wax-in-water emulsion, characterized in that it comprises at least one polyolefin wax resulting from the homopolymerization of alpha-olefins having at least 10 carbon atoms, the said wax having a melting point ranging from 50 to 80&deg; C. The composition is preferably intended for making up the lashes.

Make-up composition comprising a poly-alpha-olefin

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 topical composition separately containing a hydrophilic carrier and a solid which are intended to be mixed immediately before use, the solid being powdered ascorbic acid and the carrier containing an aqueous medium and at least one hydrophilic gelling agent, the carrier being capable of withstanding the introduction of an acidic compound. In a preferred embodiment, the carrier (L) is packaged in a container (,) closed with a cap (,) containing ascorbic acid (P), a perforable and/or detachable separator (,) being provided between the acid and the carrier.

Cosmetic and/or dermatological composition with a hydrophilic carrier and vitamin C which can be mixed immediately before use

A topical composition separately containing a hydrophilic carrier and a solid which are intended to be mixed immediately before use, the solid being powdered ascorbic acid and the carrier containing an aqueous medium and at least one hydrophilic gelling agent, the carrier being capable of withstanding the introduction of an acidic compound. In a preferred embodiment, the carrier (L) is packaged in a container (1) closed with a cap (3,6) containing ascorbic acid (P), a perforable and/or detachable separator (5) being provided between the acid and the carrier.
