An anhydrous cosmetic makeup composition contains in addition to a fatty phase formed from oils, fatty bodies and surfactants, and optionally waxes, a vesicular lipidic phase that contains at least one ionic or nonionic amphiphilic lipid and optionally additives. The anhydrous composition also preferably contains at least one cosmetically and/or dermopharmaceutically active material. In the presence of an aqueous phase these compositions release vesicles of the vesicular lipidic phase and potentialize the activity of the cosmetically and/or dermopharmaceutically active material of the composition.

Anhydrous cosmetic composition containing a fatty phase and pro-liposomes

A process for preparing a stable and anhydrous solid dispersion, containing from 20 to 95 weight percent of a fatty body, constituted of 10 to 50 weight percent of at least one wax having a melting point greater than 55&deg; C., and from 4 to 50 weight percent of a polyhydric alcohol, involves heating the fatty body and the polyhydric alcohol to a temperature between 65&deg; and 95&deg; C. and mixing the heated components in a turbine rotating at a speed greater than 1500 rpm. The resulting dispersion is employed in the production of cosmetics in stick form.

Process for the preparation of a solid dispersion of at least one polyhydric alcohol in a fatty body and the resulting dispersion for cosmetic and pharmaceutical use

The present invention relates to a cosmetic or dermopharmaceutical composition in the form of a soft paste, which can be used for making up or treating the skin or lips, comprising, in a fatty phase, from 12% to 60% by weight, relative to the total weight of the composition, of at least one wax having a melting point above 55.degree. C., the said composition having a dynamic viscosity at 25.degree. C. of between 3 and 30 pascal-seconds. The present invention also relates to the process for preparing this composition.

An anhydrous solid dispersion for use in cosmetics comprises, with respect to the total dispersion weight, 20 to 95%, preferably 40 to 85% by weight of a fatty substance constituted by 10 to 15% by weight of at least one wax having a melting point greater than 55.degree. C., 0.5 to 50%, preferably 4 to 40% by weight of a dispersed polyhydric alcohol, and 0.1 to 50%, preferably 0.5 to 20% by weight of at least one organofluorinated hydrocarbon compound.

Anhydrous solid dispersion containing organoflourinated hydrocarbon

A process for preparing a stable and anhydrous solid dispersion, containing from 20 to 95 weight percent of a fatty body, constituted of 10 to 50 weight percent of at least one wax having a melting point greater than 55.degree. C., and from 4 to 50 weight percent of a polyhydric alcohol, involves heating the fatty body and the polyhydric alcohol to a temperature between 65.degree. and 95.degree. C. and mixing the heated components in a turbine rotating at a speed greater than 1500 rpm. The resulting dispersion is employed in the production of cosmetics in stick form.
