The present invention relates to an emulsion not containing any emulsifying surfactant, in particular to an oil-in-water emulsion not containing any emulsifying surfactant, characterized in that it comprises, especially in a physiologically acceptable medium, at least composite particles comprising a core comprising at least organic or inorganic particles A; said core being covered at the surface, continuously or discontinuously, with an envelope comprising at least organic or inorganic particles B; said particles A and B having different polarities.

Emulsions stabilised by amphiphilic composite particles

The present invention relates to a process for making up the skin, including the step that consists in forming, on a deposit of a foundation composition applied to the skin, a discontinuous deposit of islets of corrective composition and/or a deposit of corrective composition including visible substances that give it an inhomogeneous appearance, said corrective composition having optical properties that locally modify the appearance of the makeup so as to create a pattern reproducing the appearance of skin relief and/or colour heterogeneities.

Makeup process

Provided is a composition, especially a cosmetic composition, that comprises at least one monoglyceride and at least one tartaric ester of monoglyceride, and at least one coated pigment and/or mineral filler. Also provided is the use of a coated pigment and/or coated mineral filler for improving the stability of a composition, especially a cosmetic composition comprising at least one monoglyceride and at least one diacetyl tartaric ester of monoglyceride. Further provided is a cosmetic treatment method that implements the composition of the invention.

Stable cosmetic composition containing a monoglyceride, a tartaric ester of monoglyceride, and a coated filler

The present invention relates to a composition in the form of an emulsion containing portions of hollow spheres of organosilicon-based material, the portions of hollow spheres having a mean diameter ranging from 0.05 to 10 &#x3bc;m. The invention also relates to physiologically acceptable emulsion compositions comprising hollow spheres, and to a process for fading out skin surface defects, in particular to reduce the sheen of the skin and/or to fade out pores, shadows under the eyes, marks, wrinkles and/or fine lines, comprising the topical application to the skin of the above-mentioned compositions.

Emulsion containing organosilicon-based portions of hollow spheres

Cosmetic composition for making up and/or caring for keratin materials, in particular the skin and/or the lips, including: at least one aqueous phase gelled with at least one polymeric gelling agent that is natural or of natural origin; and at least one oily phase gelled with at least one lipophilic gelling agent chosen from particulate gelling agents, organopolysiloxane elastomers, semi-crystalline polymers and dextrin esters, and mixtures thereof; the phases forming therein a macroscopically homogeneous mixture.

Gel-type cosmetic composition

The present invention is directed towards a cosmetic composition for making up and/or caring for keratin materials, in particular the skin and/or the lips, comprising: &#x2014;at least one aqueous phase gelled with at least one synthetic polymeric hydrophilic gelling agent; and &#x2014;at least one oily phase gelled with at least one lipophilic gelling agent chosen from particulate gelling agents, organopolysiloxane elastomers, semi-crystalline polymers and dextrin esters, and mixtures thereof; the said phases forming therein a macroscopically homogeneous mixture.

The present invention relates to a composition comprising a mixture: of hydrophobic silica aerogel particles having a specific surface area per unit of mass (S) ranging from 500 to 1500 m/g and a size expressed as the volume-average diameter (D[0.5]) ranging from 1 to 1500 &#x3bc;m, and of at least one first linear silicone oil having a viscosity greater than 50 mm/s and of at least second and third linear silicone oils having a viscosity less than or equal to 50 mm/s. The present invention also relates to a cosmetic composition comprising a mixture: of hydrophobic silica aerogel particles having a specific surface area per unit of mass (S) ranging from 500 to 1500 m/g and a size expressed as the volume-average diameter (D[0.5]) ranging from 1 to 1500 &#x3bc;m, and of at least one first linear silicone oil having a viscosity less than 10 mm/s and of at least one second linear silicone oil having a viscosity greater than or equal to 10 mm/s. The mixture of silica aerogel particles and linear silicone oils makes it possible to obtain compositions that are comfortable and soft on application, having mattifying and soft-focus properties.

The present invention relates to a composition comprising a mixture of: hydrophobic silica aerogel particles with a specific surface area per unit of mass (S) ranging from 500 to 1500 m/g and a size expressed as the mean volume diameter (D[0.5]) ranging from 1 to 1500 &#x3bc;m, and at least a first and at least a second hydrocarbon-based oil chosen from branched esters, pentacrythritol esters, hydrogenated polyolefins and fatty acid triglycerides, and mixtures thereof, the first hydrocarbon-based oil being present in a content of greater than or equal to 40% by weight of the mixture of the first and second oils.

Cosmetic composition comprising silica aerogels particles and hydrocarbon-based oils

The present invention relates to a method for the cosmetic treatment of the skin, comprising the application, to the skin:

Cosmetic treatment method using a compound that can be condensed in situ and a UV-radiation-filtering agent

A cosmetic composition for making up and/or caring for the skin and/or the lips, has, in a physiologically acceptable medium, at least interference particles with a volume-average size of less than 40 &#x3bc;m and at least one filler such that the composition also has a lightness L* of greater than 60 and a saturation C* of less than 10.

Cosmetic composition with a lightening effect

The invention relates to a cosmetic composition having an immediate anti-wrinkle effect, containing an effective amount of at least one mineral filler, with the exclusion of any mixed silicate, the mineral filler being in the form of colloid particles in a stable dispersion in an aqueous medium. The invention also relates to using such a filler as a tensing agent in and/or for preparing a cosmetic composition.
