Abstract

The present invention relates to a solid cosmetic composition in the form of a compact powder, comprising, in a physiologically acceptable medium, at least: —a pulverulent phase in an amount of greater than or equal to 35% by weight relative to the total weight of the composition, —a liquid fatty phase comprising at least one non-volatile oil, and —at least one amorphous hydrocarbon-based block copolymer. The present invention also relates to a process for coating the face, and in particular the eyelids, with the said cosmetic composition.

First claim

The invention claimed is:

1. A solid cosmetic composition consisting of, in a physiologically acceptable medium:
a pulverulent phase in an amount of greater than or equal to 35% by weight relative to a total weight of the solid cosmetic composition,
a liquid fatty phase comprising at least one non-volatile oil, wherein the at least one non-volatile oil is present in an amount of greater than or equal to 15% by weight relative to the total weight of the solid cosmetic composition,
optionally an aqueous phase,
an amorphous hydrocarbon-based block copolymer, and
optionally at least one adjuvant selected from the group consisting of preserving agents, cosmetic active agents, moisturizers, UV-screening agents, thickeners, fragrances, and mixtures thereof,
wherein the solid cosmetic composition is in a form of a compact powder,
wherein the pulverulent phase comprises at least one nacre in an amount of greater than or equal to 30% by weight relative to the total weight of the solid cosmetic composition, and
wherein the pulverulent phase comprises from 40% to 95% by weight of nacre(s) relative to the total weight of the pulverulent phase.

2. The solid cosmetic composition according to claim 1 ,
wherein the solid cosmetic composition contains the pulverulent phase in an amount of greater than or equal to 50% by weight relative to the total weight of the solid cosmetic composition.

3. The solid cosmetic composition according to claim 1 ,
wherein the solid cosmetic composition contains the at least one non-volatile oil in an amount of greater than or equal to 25% by weight relative to the total weight of the solid cosmetic composition.

4. The solid cosmetic composition according to claim 1 , wherein the at least one non-volatile oil is a C 12 -C 15 alkyl benzoate.

5. The solid cosmetic composition according to claim 1 , wherein the at least one non-volatile oil is a linear non-volatile silicone oil and/or a phenylated non-volatile silicone oil.

6. The solid cosmetic composition according to claim 1 ,
wherein the solid cosmetic composition contains the amorphous hydrocarbon-based block copolymer in an amount of greater than or equal to 1% by weight relative to the total weight of the solid cosmetic composition.

7. The solid cosmetic composition according to claim 1 ,
wherein the non-volatile oil is a C 12 -C 15 alkyl benzoate, and
the amorphous hydrocarbon-based block copolymer(s) and the C 12 -C 15 alkyl benzoate are present in a respective total content such that a weight ratio of the amorphous hydrocarbon-based block copolymer to the C 12 -C 15 alkyl benzoate is between 0.06 and 0.3.

8. The solid cosmetic composition according to claim 1 ,
wherein the solid cosmetic composition is selected from the group consisting of an eyeshadow, a blusher and a powder with a healthy-complexion effect.

9. A process for coating eyelids with the solid cosmetic composition according to claim 1 , the process comprising:
applying the solid cosmetic composition to the eyelids.

10. The solid cosmetic composition according to claim 1 ,
wherein the solid cosmetic composition is in a form of pressed powder.

11. The solid cosmetic composition according to claim 1 ,
wherein the solid cosmetic composition contains the at least one non-volatile oil in an amount of from 25% to 50% by weight relative to the total weight of the solid cosmetic composition.

12. The solid cosmetic composition according to claim 1 , wherein the amorphous hydrocarbon-based block copolymer is hydrogenated.

13. The solid cosmetic composition according to claim 1 , which contains 0.5% to 5% by weight of the hydrocarbon-based block copolymers.

14. The solid cosmetic composition according to claim 1 , which contains 1.5% to 4% by weight of the hydrocarbon-based block copolymers.

15. A method of preparing the solid cosmetic composition according to claim 1 , comprising combining the pulverulent phase, liquid fatty phase and amorphous hydrocarbon-based block copolymer in a physiologically acceptable medium.

16. The solid cosmetic composition according to claim 1 , wherein the nacre is at least one member selected from the group consisting of titanium mica coated with an iron oxide, mica coated with bismuth oxychloride, titanium mica coated with chromium oxide, and nacreous pigments based on bismuth oxychloride, mica particles at the surface of which are superposed at least two successive layers of metal oxides, and mica particles at the surface of which are superposed at least two successive layers of organic dyestuffs.

17. The solid cosmetic composition according to claim 1 , wherein
the non-volatile oil is at least one C 12 -C 15 alkyl benzoate,
the solid cosmetic composition comprises 15% to 35% by weight of the C 12 -C 15 alkyl benzoate, relative to a total weight of the solid cosmetic composition, and
the ratio between the amorphous hydrocarbon-based block copolymer to the C 12 -C 15 alkyl benzoate is from 0.06 to 0.3.

18. The solid cosmetic composition according to claim 1 , wherein the amorphous hydrocarbon-based block copolymer is selected from the group consisting of styrene-butylene/ethylene-styrene triblock copolymer, styrene-ethylene/butylene diblock copolymer, and mixtures thereof.

19. The solid cosmetic composition according to claim 1 , wherein the pulverulent phase contains at least one nacre in an amount between 30% and 70% by weight relative to the total weight of the solid cosmetic composition.

20. The solid cosmetic composition according to claim 19 , wherein the pulverulent phase contains from 50% to 90% by weight of nacre(s) relative to the total weight of the pulverulent phase.

21. The solid cosmetic composition according to claim 20 ,
wherein the solid cosmetic composition contains the at least one non-volatile oil in an amount of from 25% to 50% by weight relative to the total weight of the solid cosmetic composition.
