A composition, in particular a cosmetic composition, which may be in the form of an emulsion, the said composition comprising a specific copolymer comprised of monoolefinically unsaturated C -C carboxylic acid monomer and fatty-chain monomeric ester of acrylic acid. The invention also relates to the use of the said copolymer in cosmetics, in particular for improving the staying power of the composition.

Cosmetic composition comprising a copolymer and utilization of the copolymer in a cosmetic composition

Compositions comprising an aqueous dispersion of lipid vesicles having an aqueous core, wherein the dispersion comprises at least one uncoated pigment dispersed in the aqueous phase and wherein the lipid vesicles with an aqueous core and a lipid membrane formed from at least one fatty acid ester, these compositions being stable, of homogeneous color and containing no or virtually no lumps of pigment, and a process for dispersing a filler in an oil-in-water dispersion of lipid vesicles by means of a high-pressure homogenizer.

Aqueous composition containing nonionic lipid vesicles and at least one

The present invention relates to a cosmetic or dermatological composition comprising an emulsion of oil-in-water type formed of oily globules which are each provided with a lamellar liquid crystal coating and are dispersed in an aqueous phase. Each oily globule containing at least one lipophilic compound which is cosmetically or dermatologically active is individually coated with a monolamellar or oligolamellar layer obtained from at least one lipophilic surface-active agent, from at least one hydrophilic surface-active agent and from at least one ionic amphiphilic lipid imparting to the emulsion a pH ranging from 5.5 to 7.5, the coated oily globules having a mean diameter of less than 500 nanometers.

Cosmetic or dermatological composition comprising an oil-in-water

The present invention relates to a cosmetic or dermatological composition comprising an emulsion of oil-in-water type formed of oily globules which are each provided with a lamellar liquid crystal coating and are dispersed in an aqueous phase. Each oily globule containing at least one lipophilic compound which is cosmetically or dermatologically active is individually coated with a monolamellar or aligolamellar layer obtained from at least one lipophilic surface-active agent, from at least one hydrophilic surface-active agent and from at least one ionic amphiphilic lipid imparting to the emulsion a pH ranging from 5.5 to 7.5, the coated oily globules having a mean diameter of less than 500 nanometers.

A cosmetic composition formulated as an oil-in-water or water-in-oil emulsion, or a paste or powder contains a fatty phase comprising volatile and cyclic silicone oils of from 2-18 weight % of cyclopentadimethylsiloxane and 2-18 weight % of cyclopentadimethylsiloxane, the weight percentages based on the total weight of the composition.

Cosmetic composition comprising cyclopentadimethylsiloxane and

A composition in the form of an anhydrous gel containing a wax-free fatty phase in which are dispersed an organomodified clay, expanded thermoplastic hollow particles of polymer or copolymer formed from a monomer or a mixture of monomers containing ethylenic unsaturation and a pyrogenous silica, as well as to its uses in topical application. This composition has a creamy, non-greasy, smooth and melting texture and good stability over time. It may be used as a base for make-up products or care products for the skin and/or the face. It may contain heat-sensitive cosmetic or dermatological active agents.

Composition in the form of an anhydrous gel with a wax-free fatty phase,

A composition containing a dispersion of lipid vesicles with an aqueous core and/or of lipid vesicles with an oily core. At least one acidic compound is present in the dispersion in an amount which is sufficient to impart a pH of less than 5 to the composition. The lipid membrane of the vesicles with an aqueous core does not contain:

Acidic composition based on lipid vesicles and its use in topical

Substantially greaseless cosmetic stick, particularly for applying eye shadow, comprises a carrier of compacted powder made of materials softer than calcium carbonate having a particle size between 1 and 20 microns, while its other constituents consist of powders having a particle size not greater than 25 microns.

Compacted greaseless cosmetic stick and particularly stick of eye shadow

Cosmetic article comprises a solid support coated with an impregnating layer which carries a coating layer. The impregnating layer comprises at least one hydrosoluble polymer and the coating layer comprises a product which is thixotropic in aqueous suspension, a polymeric binder capable of forming a gel in an aqueous medium when mixed with said thixotropic product, and a mixture of cosmetic powders.
