Abstract

The present invention relates to a composition comprising from 0.1 to 30% by weight of copolymer comprising polyether blocks and polyamide blocks (PEBA), and from 70 to 99.9% by weight of a medium which is acceptable in the cosmetics industry, in the perfumery industry and/or in the pharmaceutical industry. The present invention also relates in particular to a process for incorporating a copolymer comprising polyether blocks and polyamide blocks into a cosmetic, perfumery and/or pharmaceutical medium. The subject matter of the present invention is also the use of a copolymer comprising polyether blocks and polyamide blocks (PEBA) for producing a cosmetic, pharmaceutical or perfumery product, said PEBA being incorporated in the form of a composition in accordance with the invention.

First claim

The invention claimed is:

1. A composition comprising:
from 0.1 to 30 wt % of polyether-block-amide copolymer (PEBA) and
from 70 to 99.9 wt % of a medium that is acceptable in cosmetics, in perfumery and/or in pharmacy, comprising an aqueous phase comprising at least 50% water,
said composition having at least one of the following forms: dispersion, solution, emulsion, microemulsion, nanoemulsion, dry emulsion, suspension, aerosol, gel, compact gel, gum, plastic gum, paste, mousse, cream, powder, loose powder, compact powder, expanded powder, butter, film, elastic film, or a mixture thereof.

2. The composition as claimed in claim 1 , in which said medium comprises at least one component that is alcohols, alcoholic solutions, lipid compounds, carbohydrate compounds, hydrocarbons, synthetic polymers, natural polymers, and/or plant extracts.

3. The composition as claimed in claim 1 , in which said medium further comprises an oily phase comprising at least 50% of organic solvent selected from fatty esters, fatty alcohols, fatty acids and mixtures thereof.

4. The composition as claimed in claim 1 in which said medium comprises from 0.1 to 30 wt % of surfactant based on the total weight of PEBA.

5. The composition as claimed in claim 4 in which the surfactant is an anionic surfactant or nonionic surfactant.

6. The composition as claimed in claim 4 in which the surfactant is a salt of alkyl ether sulfate and of polyoxyalkylene, a salt of dialkylsulfosuccinate, a salt of fatty acid and ethylene oxide/propylene oxide copolymers, or a mixture thereof.

7. The composition as claimed in claim 1 , characterized in that it comprises:
from 0.1 to 30% of PEBA,
from 40 to 99.9% of oily phase and/or of aqueous phase,
from 0 to 30% of surfactant,

based on the total weight of the composition.

8. The composition as claimed in claim 1 , further comprising a thickener.

9. The composition as claimed in claim 1 , characterized in that it forms a dispersion of PEBA dissolved in an oily phase dispersed in an aqueous phase in the presence of a surfactant.

10. The composition as claimed in claim 1 , characterized in that it forms a dispersion of PEBA dissolved in an aqueous phase dispersed in an oily phase in the presence of a surfactant.

11. The composition as claimed in claim 1 , said composition being a colored, non-colored and/or transparent product selected from the following products:
makeup products for the face and the human body,
care products for the face and the human body,
hair products,
perfumery products.

12. The composition as claimed in claim 11 , that is foundation, tinted cream, loose or compact powder, eye shadow, mascara, eye liner, lipstick, nail varnish;
cream, milk, lotion, mask, peeling product, cleansing and/or makeup removal products, deodorants, antiperspirants, shaving products, epilatories;
shampoos, products for shaping the hair, styling products, anti-dandruff products, products against hair loss, products against dryness of the hair, hair dyes, bleaching products;
perfume, milk, cream, or perfumed loose or pressed powder.
