Abstract: The present invention relates to a composition for topical application consisting of an aqueous phase and an oily phase, which are separate and transparent, comprising at least one surfactant that is liquid at room temperature and at atmospheric pressure, with an HLB<8 and chosen from fatty acid esters of sugar and alkyl polyglucosides, at least one branched alkane comprising from 8 to 18 carbon atoms, and from 0 to 4% by weight of silicone oils relative to the total weight of the composition. The composition according to the invention makes it possible to obtain, after shaking, an emulsion that rapidly separates again into two transparent phases, having a perfectly sharp interface and with no appearance of droplets that remain attached to the walls of the transparent container. The composition in accordance with the invention has the same makeup-removing efficacy and better sensory properties, and in particular it leaves less greasy residue on the skin.

Abstract: The invention relates to a cosmetic composition comprising, in a physiologically acceptable aqueous medium, a cucurbic acid compound of formula (I) in which R1 represents a radical COOR3, where R3 denotes H or a C1-C4 alkyl radical, which is optionally substituted by one or more hydroxyl groups; R2 represents a hydrocarbon radical having from 1 to 18 carbon atoms; and a copolymer of 2-acrylamido-2-methylpropanesulphonic acid and hydroxylated C2-C4 alkyl(meth)acrylate. Application to the care and make-up of keratin materials.

Abstract: The invention relates to a cosmetic composition in oil-in-water emulsion form comprising a cucurbic acid compound of formula (I) in which R1 represents a radical COOR3, R3 denoting H or a C1-C4 alkyl radical, optionally substituted with one or more hydroxyl groups; R2 represents a hydrocarbon-based radical containing from 1 to 18 carbon atoms; an inulin bearing hydrophobic ester or carbamate groups, an oily phase and an aqueous phase. Use for caring for and making up keratin materials.

Abstract: The present invention relates to a treatment process for human skin, comprising the topical application to said skin of a composition comprising, in a physiologically acceptable medium, a tetrapolymer of methacrylic acid, methyl methacrylate, butyl acrylate and C16-C20 alkyl (meth)acrylates, said composition being devoid of sunscreen agents. The invention likewise relates to the use of a tetrapolymer of methacrylic acid, methyl methacrylate, butyl acrylate and C16-C20 alkyl (meth)acrylates.

Abstract: The invention relates to a composition containing at least one optical brightener and at least one semi-crystalline polymer that is solid at room temperature and that has a melting point of less than 70° C., the polymer having a) a polymer skeleton and b) at least one crystallizable organic side chain and/or a crystallizable organic block forming part of the polymer skeleton, the polymer having a number-average molecular weight of greater than 2000. The invention also relates to a cosmetic process for lightening and/or bleaching the skin, using the invention composition, and to a makeup process using the invention composition.
