Abstract: A subject-matter of the present invention is a composition in the form of a water-in-oil emulsion, comprising ethylcellulose; at least one first non-volatile oil which is liquid at 25° C. chosen from saturated or unsaturated, linear or branched, C10-C26 fatty alcohols; at least one second non-volatile hydrocarbon-based oil which is liquid at 25° C. chosen from ethers of formula ROR′ or carbonates of formula RO(CO)OR′, in which formulae, identical or not, the R and R′ groups represent a saturated or unsaturated, branched or unbranched, hydrocarbon-based group comprising at most 16 carbon atoms, preferably a C3-C16 group; and also their mixtures; at least one first non-ionic hydrocarbon-based surfactant.
It relates to a transparent or translucent composition in the form of an inverse emulsion comprising from 11% to 14% by weight, with respect to the total weight of the composition, of ethylcellulose; from 30% to 50% by weight, with respect to the total weight of the composition, of octyldodecanol; at least dicaprylyl ether as second oil, optionally in combination with dicaprylyl carbonate or pentaerythrityl tetrastearate; the first oil(s)/second oil(s) ratio by weight varying from 50/50 to 70/30; from 2% to 7% by weight, with respect to the total weight of the composition, of a mixture of sucrose laurate and of sucrose palmitate; from 10% to 20% by weight, with respect to the total weight of the composition, of water and of glycerol; optionally at least one water-soluble solvent chosen from saturated C1-C5 monoalcohols; the content of water, polyol(s), if appropriate water-soluble solvent(s) and surfactants being of between 15% and 25% by weight, with respect to the total weight of the composition; at least one fat-soluble or water-soluble dye.
It finally relates to a method for making up and/or caring for human keratin materials which employs them.

Abstract: The present invention relates to a composition in the form of a water-in-oil emulsion comprising:



ethyl cellulose;
at least one first non-volatile oil that is liquid at 25° C., chosen from saturated or unsaturated, linear or branched C10-C26 fatty alcohols;
at least one second non-volatile hydrocarbon-based oil that is liquid at 25° C. chosen from ethers of formula ROR′, carbonates of formula RO(CO)OR′, in which formulae the R and R′ groups, which may be identical or different, represent a saturated or unsaturated, branched or unbranched, hydrocarbon-based group comprising at most 16 carbon atoms, preferably a C3-C16 group; and also mixtures thereof;
at least one first non-ionic hydrocarbon-based surfactant.




It also relates to a method for making up and/or caring for human keratin materials, in particular the skin or the lips, and preferably the lips, in which said composition is applied.

Abstract: The present invention relates to a cosmetic composition comprising, in a physiologically acceptable medium: at least one volatile oil, at least one volatile alcohol, and at least one natural resin; and to the use of such a composition for improving the persistence and/or the resistance to friction without increasing the tacky effect of a film obtained by applying said composition to the keratin materials.
