Water-in-oil (W/O) emulsion stabilized with a lipophilic emulsifier and a hydrophobically modified polysaccharide
The invention relates to a composition in the form of a water-in-oil emulsion comprising an aqueous phase dispersed in an oily phase and containing: a) at least one fatty acid ester of a polyol; and b) at least one hydrophobically modified polysaccharide chosen from inulins, celluloses and derivatives thereof, starches and agars, and mixtures thereof. In particular, the fatty acid ester of a polyol is polyglyceryl-4 diisostearate/polyhydroxystearate/-sebacate. It also relates to a process for caring for, making up and/or removing makeup from the skin, including the scalp, the hair and the lips, comprising the topical application of such a composition to the skin, the scalp or the lips.
1. A composition in the form of a water-in-oil emulsion comprising an aqueous phase dispersed in an oily phase and comprising:
fatty acid ester of a polyol present in the composition at a content ranging from 0.5% to 15%, relative to the total weight of the composition in which the fatty acid ester of a polyol is polyglyceryl-4 diisostearate/polyhydroxystearate/sebacate of formula
where PHS denotes polyhydroxystearic acid and IS denotes isostearic acid
and
Inulin lauryl carbamate present at a content ranging from 0.01% to 20% by weight relative to the total weight of the composition, wherein the composition is free of silicones and free of volatile oils of synthetic origin.
2. A composition according to claim 1 , wherein the oily phase is present in the composition at a content ranging from 10% to 30%, relative to the total weight of the composition.
3. A nontherapeutic process for caring for, making up or removing makeup from the skin, comprising the application to the skin, the hair and/or the lips, of a composition as defined in claim 1 .
4. A process for reducing the visible or tactile irregularities of the surface of the skin, comprising the topical application to the skin of the composition as defined in claim 1 .
5. A composition according to claim 1 , in which the fatty acid ester of a polyol is present in the composition at a content ranging from 1% to 5%, relative to the total weight of the composition.
6. A composition according to claim 1 , in which the fatty acid ester of a polyol is present in the composition at a content ranging from 1.5% to 3.5%, relative to the total weight of the composition.
7. A composition according to claim 1 , wherein the inulin lauryl carbamate is present at a content ranging from 0.05% to 15% by weight relative to the total weight of the composition.
8. A composition according to claim 1 , wherein the inulin lauryl carbamate is present at a content ranging from 0.1% to 5% by weight relative to the total weight of the composition.
9. A composition according to claim 1 , wherein the inulin lauryl carbamate is present at a content ranging from 0.5% to 3% by weight relative to the total weight of the composition.
10. A composition according to claim 1 , wherein the inulin lauryl carbamate is present at a content ranging from 0.1% to 3% by weight relative to the total weight of the composition.
11. A composition according to claim 1 , wherein the emulsion does not undergo phase separation after two months at 37° C.
