NOVEL PHOTOPROTECTIVE SYSTEM

摘要

The present invention concerns a topical, cosmetic or pharmaceutical preparation containing a combination of 3 or 4 solar filters comprising: —one or two UVA filters to obtain a critical wavelength >370 nm, chosen from among: (i)—5,6,5,6-tetraphenyl-3,3′-(1,4-phenylene)-bis[1,2,4]triazine; (ii) 1,1′-(1,4-piperazinediyl)bis[1-[2-[4-(diethylamino)-2-hydroxybenzoyl]phenyl]-methanone; (iii)—Butyl Methoxydibenzoylmethane (BMDBM), in a quantity less than 2% by weight with regard to the total weight of said composition; (iv)—Hexyl-[4-(diethylamino)-2-hydroxybenzoyl]benzoate, -2,4-Bis[4-(2-ethyl-hexyloxy)-2-hydroxyphenyl]-6-(4-methoxyphenyl)-1,3,5-triazine=(BEMT), —one or two filters chosen from among UVB filters, except octocrylene, PABA and ethylhexyl methoxycinnamate, said composition also containing a pharmaceutically or cosmetically acceptable excipient.
