Title
(EN) MINERAL SUNSCREEN COMPOSITIONS
(FR) COMPOSITIONS MINÉRALES D'ÉCRAN SOLAIRE
Abstract
(EN)
A sunscreen composition in the form of a water-in-oil emulsion comprising: a) a water phase of about 20% to about 60% by weight relative to the total weight of the sunscreen composition; b) one or more mineral UV filtering agents; c) one or more oil thickening agents selected from poly C10-30 alkyl acrylate, hydrogenated jojoba oil and its derivatives and mixtures thereof; wherein the total amount of oil thickening agents is about 0.5% to about 4% by weight relative to the total weight of the sunscreen composition; wherein the amount of hydrogenated jojoba oil and its derivatives is no more than 1.5 times the amount of poly C10-30 alkyl acrylate; wherein the composition has a viscosity of about 0.1 Pa·s to about 5 Pa·s at 25 ºC at about 10 rad/s; and wherein the inflection point of the largest viscosity transition at about 10 rad/s is in the range from about 30 ºC to about 40 ºC.
(FR)
L'invention concerne une composition d'écran solaire sous la forme d'une émulsion eau-dans-huile comprenant : a) une phase aqueuse d'environ 20 % à environ 60 % en poids par rapport au poids total de la composition d'écran solaire ; b) un ou plusieurs agents minéraux de filtration des UV ; c) un ou plusieurs agents épaississants d'huile choisis parmi le polyacrylate d'alkyle en C10 à C30, l'huile de jojoba hydrogénée et ses dérivés ainsi que leurs mélanges ; la quantité totale d'agents épaississants d'huile étant d'environ 0,5 % à environ 4 % en poids par rapport au poids total de la composition d'écran solaire ; la quantité d'huile de jojoba hydrogénée et ses dérivés n'étant pas supérieure à 1,5 fois la quantité de polyacrylate d'alkyle en C10 à C30 ; la composition ayant une viscosité d'environ 0,1 Pa.s à environ 5 Pa.s à 25 °C à environ 10 rad/s ; et le point d'inflexion de la transition de viscosité la plus grande à environ 10 rad/s s'inscrivant dans la plage d'environ 30 °C à environ 40 °C.
