(FR) COMPOSITION COSMETIQUE
Abstract
(EN)
To provide a cosmetic composition having excellent ultraviolet protection against both UVB and UVA, causing neither unpleasant whitening to the applied skin nor skin irritation, and ensuring good feeling on use and hight safety and high stability without causing decomposition of the ingredients blended in the cosmetic material, sch as organic ultraviolet absorber. A cosmetic composition obtained by using fine particulate titanium oxide and fine particulate zinc oxide each surface-treated with silica, alumina or alumina/silica and having a primary particle size of 0.01 to 0.2 $g(m)m in combination and blending titanium oxide and zinc oxide at a mass ratio of 1:4 to 2:3, wherein SPF is maintained as compared with the case where the mass ratio of titanium oxide to zinc oxide is 1:0, and when applied to a thickness of 10 $g(m)m, the whiteness W value measured using the CIE color specification system is 20 or less.

L'invention concerne une composition permettant d'assurer une excellente protection contre les ultraviolets, agissant à la fois contre les UVA et le UVB, ne provoquant ni blanchiment déplaisant de la peau, ni irritations cutanées, donnant une sensation agréable à l'application et présentant une sécurité et une stabilité élevées, et dans laquelle la décomposition des ingrédients incorporés dans le produit cosmétique, tels que les filtres UV organiques, est évitée. On prépare cette composition cosmétique en combinant de l'oxyde de titane en particules fines et de l'oxyde de zinc en particules fines, ayant tous deux subi un traitement de surface à base de silice, d'alumine, ou d'une combinaison alumine/silice, et dont les particules présentent une taille initiale comprise entre 0,01 et 0,2 $g(m)m, puis en mélangeant l'oxyde de titane et l'oxyde de zinc selon en rapport en masse de compris entre 1 :4 et 2 :3. Ce mélange présente un FPS comparable à un produit comprenant un rapport en masse oxyde de titane/oxyde de zinc de 1 :0, et lorsqu'elle est appliquée sur la peau en couche d'une épaisseur de 10 $g(m)m, la valeur de blancheur W mesurée selon le système de détermination des couleurs de la C. I. E est égale ou inférieure à 20.
