Abstract

The present invention relates to a composition comprising, in a cosmetically acceptable carrier, at least one UV screening system, characterized in that it comprises:
(i) at least one screening agent of lipophilic hydroxybenzophenone type; and (ii) at least one silicon-comprising s-triazine of formula (III) substituted by at least two alkylaminobenzoate groups.

In some embodiments, the composition also includes:
(iii) a dibenzoylmethane derivative.

First claim

The invention claimed is:

1. A composition comprising:
(i) 0.01 to 10% by weight of n-hexyl 2-(4-diethylamino-2-hydroxybenzoyl)benzoate of formula (a):

and

2,4,6-Tris(biphenyl-4-yl)-1,3,5-triazine,
2,4,6-Tris(dineopentyl 4′-aminobenzalmalonate)-s-triazine,
2,4,6-Tris(diisobutyl 4′-aminobenzalmalonate)-s-triazine,
2,4-Bis(dineopentyl 4′-aminobenzalmalonate)-6-(n-butyl 4′-aminobenzoate)-s-triazine,
methylene bis-benzotriazolyl tetramethylbutylphenol,
polysilicone-15,
dineopentyl 4′-methoxybenzalmalonate,
1,1-Dicarboxy(2,2′-dimethylpropyl)-4,4-diphenylbutadiene,
2,4-Bis[4-[5-(1,1-dimethylpropyl)benzoxazol-2-yl]phenylimino]-6-(2-ethylhexyl)imino-1,3,5-triazine, and
a mixture thereof.

3. The composition of claim 1 , further comprising monopotassium monocetyl phosphate.

4. The composition of claim 1 , further comprising water.

5. The composition of claim 1 , further comprising triethanolamine.

6. The composition of claim 1 , further comprising a preserving agent.

7. The composition of claim 1 , further comprising C 12 -C 15 alkyl benzoate.

8. The composition of claim 1 , further comprising a PEG 100 stearate/glyceryl stearate mixture.

9. The composition of claim 1 , further comprising dimethicone.

10. The composition of claim 1 , in the form of an emulsion.

11. The composition of claim 1 , further comprising isohexadecane.

12. The composition of claim 1 , further comprising a copolymer of acrylic acid and of C 10 -C 30 alkyl methacrylate.

13. The composition of claim 1 , further comprising cyclopentadimethylsiloxane.

14. The composition of claim 1 in the form of an emulsion and further comprising a preserving agent, water, and dimethicone.

15. The composition of claim 1 , further comprising isohexadecane.

16. The composition of claim 1 , further comprising a copolymer of acrylic acid and of C 10 -C 30 alkyl methacrylate.

17. A method for protecting the skin and/or keratin materials against UV radiation comprising applying the composition of claim 1 to the skin and/or keratin materials.
