Abstract

A subject-matter of the present invention is a cosmetic composition expanded in volume, in the form of an oil-in-water emulsion, comprising an internal fatty phase and an external aqueous phase comprising at least one inulin modified by hydrophobic chains and at least two gelling agents for the aqueous phase, one of the two gelling agents being chosen from unmodified clays, in particular montmorillonites, hectorites, smectites, bentones or laponites, or cellulose polymers, such as hydroxyethylcellulose, hydroxypropylcellulose, methylcellulose, ethylhydroxyethylcellulose, carboxymethylcellulose and quaternized cellulose derivatives, and the other gelling agent being chosen from gums arabic, guar gum, xanthan derivatives, karaya gum or locust bean gum, the said internal fatty phase being present in a content ranging from 5 to 50% by weight.

Claims

1. A cosmetic composition comprising:

an internal fatty phase and

an external aqueous phase;

wherein

the composition is an oil in water emulsion,

the composition is expanded in volume,

a content of the internal fatty phase is from 5 to 50% by weight, and

the external aqueous phase comprises;

at least one inulin modified by hydrophobic chains, and

at least two gelling agents,

wherein

a first of the at least two gelling agents is an unmodified clay or a cellulose polymer, and

a second of the at least two gelling agents is one selected from the group consisting of gums arabic, guar gum, xanthan derivatives, karaya gum, and locust bean gum.

2. The composition according to claim 1, wherein the first of the at least two gelling agents is an unmodified clay.

3. The composition according to claim 1, wherein the first of the at least two gelling agents is smectite and the second of the at least two gelling agents is xanthan gum.

4. The composition according to claim 1, wherein the content of the internal fatty phase is from 15 to 30% by weight.

5. The composition according to claim 1, further comprising at least one wax in a content ranging from 1 to 15% by weight, with respect to the total weight of the composition.

6. The composition according to claim 1, wherein a content of the at least two gelling agents on a dry basis is from 0.01% to 30% by weight, with respect to the total weight of the composition.

7. The composition according to claim 1, further comprising pulverulent phase in a content ranging from 1 to 30% by weight, with respect to the total weight of the composition.

8. The composition according to claim 1, wherein the inulin is obtained from endive.

9. The composition according to claim 1, wherein the hydrophobic chains are selected from the group consisting of saturated or unsaturated and linear or branched hydrocarbon chains having from 1 to 50 carbon atoms, divalent cycloaliphatic groups, organopolysiloxane chains comprising one or more ester, amide, urethane, carbamate, thiocarbamate, urea, thiourea and/or sulphonamide functional groups, and divalent aromatic groups.

10. The composition according to claim 1, wherein the inulin exhibits a degree of polymerization of 2 to approximately 1000 and a degree of substitution of less than 2 on the basis of one fructose unit.

11. The composition according to claim 1, wherein the hydrophobic chains comprise at least one alkylcarbamate group of formula R—

NH—

CO—

in which R is an alkyl group having from 1 to 22 carbon atoms.

12. The composition according to claim 1, wherein the hydrophobic chains are laurylcarbamate groups.

13. The composition according to claim 1, wherein a % by weight of the inulin is from 0.01 to 20% by weight, with respect to the total weight of the composition.

14. The composition according to claim 1, further comprising:

nonhydrogenated lecithin obtained from a source selected from the group consisting of soybean, sunflower, eggs and mixtures thereof.

15. A method for making up and/or for caring for keratinous substances, comprising:

applying to the said keratinous substance, the composition according to claim 1.

16. The cosmetic composition according to claim 1, wherein the unmodified clay is one selected from the group consisting of montmorillonites, hectorites, smectites, bentones and laponites.

17. The cosmetic composition according to claim 1, wherein the cellulose polymer is one selected from the group consisting of hydroxyethylcellulose, hydroxypropylcellulose, methylcellulose, ethylhydroxyethylcellulose, carboxymethylcellulose and quaternized cellulose derivatives
