Abstract

The invention relates especially to a composition in the form of an oil-in-water emulsion comprising an inner fatty phase and an outer aqueous phase and containing: a) at least 0.01% by weight and preferably at least 0.05% by weight, relative to the total weight of the composition, of at least one inulin modified with hydrophobic chains, and b) at least 0.05% by weight and preferably at least 0.1% by weight, relative to the total weight of the composition, of at least one thickening polysaccharide of plant origin, the said composition being free of silicones. The invention also relates to a cosmetic process using the said composition.

First claim

The invention claimed is:

1. A composition, comprising:
a) at least 0.01% by weight, relative to the total weight of the composition, of at least one inulin modified with hydrophobic chains, and
b) at least 0.05% by weight, relative to the total weight of the composition, of at least one thickening polysaccharide of plant origin,
wherein
the at least one thickening polysaccharide of plant origin is a (C 1 -C 3 ) hydroxyalkyl cellulose modified with hydrophobic chains comprising from 8 to 30 carbon atoms,
the hydrophobic chain modifying the at least one inulin comprises an alkyl carbamate group of formula (I):
R—NH—CO—  (I)

wherein R is an alkyl group having 1 to 22 carbon atoms,
the composition is an oil in water emulsion having an inner fatty phase and an outer aqueous phase,
the composition does not comprise a silicone, and
the composition does not comprise an emulsifying polymer of petrochemical or synthetic origin and does not comprise a thickening polymer of petrochemical or synthetic origin.

2. The composition according to claim 1 , wherein the inner fatty phase is at least 2% by weight relative to the total weight of the composition.

3. The composition according to claim 1 , wherein the inulin modified with hydrophobic chains is from 0.01% to 20% by weight relative to the total weight of the composition.

4. The composition according to claim 1 , wherein an inulin modified with hydrophobic chains/inner fatty phase weight ratio is from 1:0.1 to 0.1:60.

5. The composition according to claim 1 , wherein the hydrophobic chains are lauryl carbamate groups.

6. The composition according to claim 1 , comprising at least two thickening polysaccharides of plant origin.

7. The composition according to claim 1 , wherein the polysaccharide is from 0.05% to 10% by weight relative to the total weight of the composition.

8. The composition according to claim 1 , wherein the composition is free of surfactant.

9. A non-therapeutic process for caring for, making up or removing makeup from the skin, the scalp, the hair and/or the lips, comprising applying to the skin, the hair and/or the lips a composition according to claim 1 .
