Compositions containing an UV-B filter of the cinnamic acid ester type, a UV-A filter of the dibenzoylmethane type and a derivative of s-triazine; process of photostabilisation

摘要

the present invention relates to a composition, especially a cosmetic composition for topical use containing the association of a uv-b filter of cinnamic acid ester, a uv filter - type derived from dibenzoylmethane and an s-triazine with two groups () inobenzalmalonate congested and a group of the formula (i) and ethyl-4-aminobenzoate.;it also relates to a method of photo stabilization against uv radiation of at least a uv filter - b type ester of cinnamic acid in the presence of a uv filter - type derived from dibenzoylmethane involving mixing at least one audit filters with notes two groups (a group) and aminobenzalmalonate congested ethyl-4-aminobenzoate of formula (i).;the present invention is related to the use of notes in a composite composition comprising in a support cosmu00e9tiquement acceptable, a uv-b filter of cinnamic acid ester.a uv filter - type derivative of dibenzoylmethane, in order to improve the efficiency of the composition with respect to the uv-b radiation, as well as to maintain the balance of uva / uvb during exposure to sunlight.
