Abstract

The invention relates to a composition in the form of an oil-in-water emulsion and its use that contains in a physiologically acceptable medium,
i) at least 0.005% by weight, preferably at least 0.01% by weight, relative to the total weight of the composition, of at least one inulin modified with hydrophobic chains, and ii) at least 0.01% by weight, preferably at least 0.05% by weight, of active substance relative to the total weight of the composition, of at least one hydrophilic acrylic polymer selected from the at least partially neutralized, crosslinked acrylic homopolymers or copolymers, the polyacrylamidomethylpropanesulphonic acid (AMPS) homopolymers and mixtures thereof.

First claim

The invention claimed is:

1. A composition in the form of an oil-in-water emulsion comprising, in a physiologically acceptable medium,
i) at least 0.005% by weight relative to the total weight of the composition, of an inulin modified with hydrophobic chains,
ii) at least 0.01% by weight relative to the total weight of the composition, of a neutralized, crosslinked sodium polyacrylate,

wherein the composition is stable for 2 months at 37° C. and 45° C. and which is free of surfactant.

2. The composition according to claim 1 , comprising at least 15% by weight of fatty phase, relative to the total weight of the composition.

3. The composition according to claim 1 , wherein the hydrophobically modified inulin/fatty substance ratio ranges from 1:0.1 to 0.1:60.

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

5. The composition according to claim 1 , wherein
neutralized, crosslinked sodium polyacrylate is present in an amount of active substance ranging from 0.05% to 15% by weight relative to the total weight of the composition.

6. A non-therapeutic method of caring for, making up or removing makeup from the skin, including the scalp, hair and/or lips, comprising the application to the skin, hair and/or lips of a composition according to claim 1 .
