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.

First claim

The invention claimed is:

1. A composition 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 (20-25° C.) and at atmospheric pressure (760 mmHg or 1.013×10 5 Pa), 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.

2. The composition according to claim 1 , in which the at least one surfactant that is liquid at room temperature and at atmospheric pressure, with an HLB<8 comprise one or more linear or branched, saturated or unsaturated hydrocarbon-based chains, comprising from 11 to 44 carbon atoms.

3. The composition according to claim 1 , in which the fatty acid ester(s) of sugar are monoesters or polyesters of fatty acid and of sugar or of alkyl sugar, which esters may be oxyalkylenated, or polyglycerolated.

4. The composition according to claim 3 , in which the fatty acid ester(s) of sugar are chosen from monoesters or diesters of a C11-C22, bearing a linear or branched, saturated or unsaturated hydrocarbon-based chain, comprising from 11 to 22 carbon atoms, and of sugar or of alkyl sugar.

5. The composition according to claim 3 , in which the fatty acid ester(s) of sugar are chosen from fatty acid esters of sucrose, maltose, glucose, fructose, mannose, galactose, arabinose, xylose, lactose, trehalose or methylglucose.

6. The composition according to claim 1 , in which the fatty acid ester(s) of sugar result from the reaction of a fatty acid whose fatty unit comprises an unsaturated linear hydrocarbon-based chain comprising from 12 to 24 carbon atoms, and of a (C 1 -C 4 alkyl) sugar.

7. The composition according to claim 1 , in which the fatty acid ester of sugar is methylglucose dioleate.

8. The composition according to claim 1 , in which the alkyl polyglucoside(s) are chosen from the compounds having the following general formula:
RO-(G) a

in which R denotes a saturated or unsaturated, linear or branched hydrocarbon-based chain comprising from 12 to 44 carbon atoms, the group G denotes a saccharide residue comprising from 5 to 6 carbon atoms and a is a number ranging from 1 to 10.

9. The composition according to claim 8 , in which the saccharide residue is chosen from glucose, dextrose, saccharose, fructose, galactose, maltose, maltotriose, lactose, cellobiose, mannose, ribose, dextran, talose, allose, xylose, levoglucan, cellulose, starch and methylglucose.

10. The composition according to claim 1 , in which the alkyl polyglucoside(s) are chosen from the compounds having the following formula:
R′O-G

in which R′ denotes a saturated branched alkyl radical comprising from 12 to 44 carbon atoms, and the group G denotes a saccharide residue comprising from 5 to 6 carbon atoms.

11. The composition according to claim 8 , in which the alkyl polyglucoside is octyldodecyl xyloside.

12. The composition according to claim 1 , in which the branched alkane(s) comprising from 8 to 18 carbon atoms are chosen from C 8 -C 18 isoalkanes.

13. The composition according to claim 1 , in which the branched alkane(s) comprising from 8 to 18 carbon atoms are present in the composition in an amount at least equal to 40% by weight relative to the total weight of the oily phase.

14. A cosmetic process which comprises applying a composition according to claim 1 to hair.

15. A cosmetic process for removing makeup from, cleansing and/or caring for the skin, the lips and/or the eyes, in which a composition according to claim 1 is applied to the skin, the lips and/or the eyes.

16. The composition according to claim 2 , in which the fatty acid ester(s) of sugar are monoesters or polyesters of fatty acid and of sugar or of alkyl sugar, which esters may be oxyalkylenated, or polyglycerolated.

17. The composition according to claim 4 , in which the fatty acid ester(s) of sugar are chosen from fatty acid esters of sucrose, maltose, glucose, fructose, mannose, galactose, arabinose, xylose, lactose, trehalose or methylglucose.

18. The composition according to claim 3 , in which the fatty acid ester(s) of sugar are chosen from fatty acid esters of sucrose, glucose or methylglucose.

19. The composition according to claim 3 , in which the fatty acid ester(s) of sugar are chosen from fatty acid esters of methylglucose.

20. The composition according to claim 2 , in which the fatty acid ester(s) of sugar result from the reaction of a fatty acid whose fatty unit comprises an unsaturated linear hydrocarbon-based chain comprising from 12 to 24 carbon atoms, and of a (C 1 -C 4 alkyl) sugar.
