摘要 |
The present invention relates to cosmetic compositions containing sunscreens against sun radiations ranging from 280 to 380 nm and their use for the protection of the skin from UV radiations. The sunscreens of the present invention are a combination consisting of, with respect to the weight of the composition: a) from 1 to 10% of one or more derivatives of dibenzoylmethane of formula (I) <CHEM> wherein Q is hydrogen, straight or branched C1-C4 alkoxy and G is C1-C8 straight or branched alkyl; b) from 0.5 to 10% of one or more derivatives of the benzophenone of formula (II): <CHEM> wherein R1 is hydrogen or a straight or branched C1-C8 alkyl, R2 is hydrogen or an SO3M group, wherein M is hydrogen, an alkali metal or a mono- or polyalkyl substituted ammonium group; c) from 1 to 10% of one or more derivatives of the triazine of formula (III) <CHEM> wherein R3 is a straight or branched C1-C8 alkyl, R4 has independently the same meanings of R3 or is hydrogen or an alkali metal; with the condition that the weight ratio between the compounds of formula (II) and the compounds of formula (I) is at least 0.5. |
