Abstract

Cosmetic or dermatological preparations which have a UVA balance of more than 15, and use thereof.

Claims (31)

1. A cosmetic preparation, wherein the preparation comprises at least one UV filter substance, exhibits a UVA balance of higher than 15, and further comprises one or more of creatine, creatinine, taurine, ubiquinol, ubiquinone, folic acid, 8-hexadecene-1,16-dicarboxylic acid, biotin, isoflavone, a licochalcone, silymarin, silyphos, an extract of licorice, dihydroxyacetone, erythrulose and/or further comprises from 1% to 30% by weight of glycerol, based on a total weight of the preparation.

2. The preparation of claim 1 , wherein the preparation exhibits a UVA balance of higher than 22.

3. The preparation of claim 1 , wherein the preparation exhibits a UVA balance of higher than 30.

4. The preparation of claim 1 , wherein the preparation exhibits a UVA balance of higher than 40.

5. The preparation of claim 1 , wherein the at least one UV filter substance is selected from water-soluble UV filters, UV filters which are liquid at room temperature, organic pigments, inorganic pigments, and broadband filters.

6. The preparation of claim 5 , wherein the at least one UV filter substance comprises at least one triazine compound.

7. The preparation of claim 5 , wherein the at least one UV filter substance comprises one or more water-soluble UVA filter substances.

8. The preparation of claim 1 , wherein the preparation comprises at least one UV filter substance which is selected from benzoxazole compounds and hydroxybenzophenones.

9. The preparation of claim 1 , wherein the preparation exhibits a sun protection factor, determined in accordance with COLIPA method, of at least 20.

10. The preparation of claim 2 , wherein the preparation exhibits a sun protection factor, determined in accordance with COLIPA method, of at least 30.

11. The preparation of claim 1 , wherein the preparation comprises from 1% to 10% by weight of glycerol, based on a total weight of the preparation.

12. The preparation of claim 1 , wherein the preparation comprises one or more of creatine, creatinine, taurine, ubiquinol, ubiquinone, folic acid, 8-hexadecene-1,16-dicarboxylic acid, biotin, isoflavone, licochalcones, silymarin, silyphos, extracts of licorice, dihydroxyacetone, and erythrulose.

13. The preparation of claim 1 , wherein the preparation comprises at least one of creatine and creatinine.

14. The preparation of claim 1 , wherein the preparation comprises taurine.

15. The preparation of claim 1 , wherein the preparation comprises at least one of creatine, creatinine and taurine in a total concentration of from 0.1% to 2% by weight, based on a total weight of the preparation.

16. The preparation of claim 1 , wherein the preparation comprises at least one of phenylene-1,4-bis(2-benzimidazyl)-3,3′-5,5′-tetrasulfonic acid, 2,4-bis[5-1(dimethylpropyl)benzoxazol-2-yl(4-phenyl)imino]-6-(2-ethylhexyl)imino-1,3,5-triazine, and hexyl 2-(4′-diethylamino-2′-hydoxybenzoyl)benzoate.

17. The preparation of claim 1 , wherein the preparation comprises at least 0.5% by weight, based on a total weight of the preparation, of at least one organic broadband filter.

18. The preparation of claim 17 , wherein the at least one organic broadband filter is selected from asymmetrically substituted s-triazine compounds and benzotriazoles.

19. The preparation of claim 18 , wherein the preparation comprises 2,4-bis{[4-(2-ethylhexyloxy)-2-hydroxy]phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine.

20. The preparation of claim 1 , wherein the preparation provides an independent Endogenous Protection Factor (EPF ind ) of greater than 1.5.

21. The preparation of claim 1 , wherein the preparation exhibits a UVA balance of higher than 22 and a sun protection factor, determined in accordance with COLIPA method, of at least 20.

22. The preparation of claim 1 , wherein the preparation exhibits a UVA balance of higher than 30 and a sun protection factor, determined in accordance with COLIPA method, of at least 30.

23. A cosmetic preparation, wherein the preparation comprises at least one UV filter substance and exhibits a UVA balance of higher than 15, the at least one UV filter substance comprising at least 0.5% by weight, based on a total weight of the preparation, of at least one organic broadband filter.

24. The preparation of claim 23 , wherein the preparation exhibits a UVA balance of higher than 22.

25. The preparation of claim 23 , wherein the preparation exhibits a UVA balance of higher than 30.

26. The preparation of claim 23 , wherein the preparation exhibits a sun protection factor, determined in accordance with COLIPA method, of at least 20.

27. The preparation of claim 25 , wherein the preparation exhibits a sun protection factor, determined in accordance with COLIPA method, of at least 30.

28. The preparation of claim 23 , wherein the preparation provides an independent Endogenous Protection Factor (EPF ind ) of greater than 1.5.

29. The preparation of claim 23 , wherein the at least one organic broadband filter is selected from asymmetrically substituted s-triazine compounds and benzotriazoles.

30. The preparation of claim 29 , wherein the preparation comprises 2,4-bis{[4-(2-ethylhexyloxy)-2-hydroxy]phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine.

31. The preparation of claim 23 , wherein the preparation further comprises one or more of glycerol, creatine, creatinine, taurine, ubiquinol, ubiquinone, folic acid, 8-hexadecene-1,16-dicarboxylic acid, biotin, isoflavone, a licochalcone, silymarin, silyphos, an extract of licorice, dihydroxyacetone, erythrulose.
