Abstract

Abstract Translated from French L'invention concerne une émulsion cosmétique filtrant les radiations UV de longueurs d'onde comprises entre 280 et 400 nm, comprenant, dans la phase huileuse, la 2,4,6-tris[p-(2′-éthylhexyl-1′-oxycarbonyl)anilino]-1,3,5-triazine et, dans la phase aqueuse, l'acide benzène 1,4-[(3-méthylidène camphométhyl sulfonique)], partiellement ou totalement neutralisé, de formule :dans laquelle A désigne un atome d'hydrogène, un métal alcalin, un groupement N(R)₄⁺, R désignant un atome d'hydrogène ou un radical alkyle ou hydroxyalkyle en C₁-C₄, ou encore un groupementMn+n où M<sup>n+</sup> est un cation métallique polyvalent dans lequel n est égal à 2 ou 3 ou 4, M<sup>n+</sup> désignant de préférence Ca²⁺, Zn²⁺, Mg²⁺, Ba²⁺, Al³⁺ ou Zr⁴⁺.L'émulsion cosmétique filtrante selon l'invention possède un indice de protection amélioré. The invention relates to a cosmetic emulsion which filters UV radiation of wavelengths between 280 and 400 nm, comprising, in the oily phase, 2,4,6-tris [p- (2′-ethylhexyl-1′- oxycarbonyl) anilino] -1,3,5-triazine and, in the aqueous phase, benzene 1,4 - [(3-methylidene camphomethyl sulfonic)] acid, partially or totally neutralized, of formula: in which A denotes a hydrogen atom, an alkali metal, an N (R) ₄⁺ group, R denoting a hydrogen atom or a C₁-C₄ alkyl or hydroxyalkyl radical, or else an Mn + n group where M <sup> n + </ sup> is a polyvalent metal cation in which n is equal to 2 or 3 or 4, M <sup> n + </sup> preferably denoting Ca²⁺, Zn²⁺, Mg²⁺, Ba²⁺, Al³⁺ or Zr⁴⁺.L The filtering cosmetic emulsion according to the invention has an improved protection index.
