Title (EN) OIL-IN-WATER EMULSION COMPRISING A MIXTURE OF SPHERICAL AND NON-SPHERICAL SCREENING PARTICLES OF COMPOSITE MATERIAL
(FR) ÉMULSION HUILE-DANS-EAU COMPRENANT UN MÉLANGE DE PARTICULES COMPOSITES FILTRANTES SPHÉRIQUES ET NON SPHÉRIQUES
Abstract: front page image
(EN)The present invention concerns a composition in the form of an oil-in-water emulsion containing, in a cosmetically acceptable medium, a mixture of composite particles comprising: a) at least spherical composite particles A with a mean size of between 0.1 and 30 µm comprising a matrix and an inorganic UV-screening agent, the content of inorganic screening agent in a particle ranging from 1% to 70% by weight, b) at least non-spherical composite particles B with a mean size of between 0. and 30 µm comprising a matrix and an inorganic UV-screening agent, the content of inorganic screening agent in a particle ranging from 1% to 70% by weight.
(FR)L'invention concerne une composition sous forme d'émulsion huile-dans-eau qui contient, dans un milieu cosmétiquement acceptable, un mélange de particules composites comprenant : a) au moins des particules composites sphériques A ayant une taille moyenne comprise entre 0,1 et 30 µm et comprenant une matrice et un agent inorganique filtrant les UV, la teneur en agent filtrant inorganique dans une particule allant de 1% à 70% en poids, b) au moins des particules composites non sphériques B ayant une taille moyenne comprise entre 0,1 et 30 µm et comprenant une matrice et un agent inorganique filtrant les UV, la teneur en agent filtrant inorganique dans une particule allant de 1% à 70% en poids.
