Title (EN) WATER BASED CONCENTRATED PRODUCT FORMS OF OIL-SOLUBLE ORGANIC UV ABSORBERS
(FR) FORMES DE PRODUIT CONCENTRÉ À BASE D'EAU D'ABSORBEURS UV ORGANIQUES SOLUBLES DANS L'HUILE
Abstract:
(EN) An aqueous polymer dispersion with an average particle size of less than 1000 nm comprising a) a polymer carrier prepared by heterophase radical polymerization of at least one ethyleni- cally unsaturated monomer in the presence of b) an oil-soluble organic UV absorber selected from the class of p-aminobenzoic acid derivatives; salicylic acid derivatives; benzophenone derivatives; diphenyl acrylate derivatives; benzofuran derivatives; polymeric UV absorbers, comprising one or more organosilicon radicals; cinnamic acid derivatives; camphor derivatives; s-triazine derivatives; trianilino-striazine derivatives; menthyl anthranilates; and benzotriazole derivatives; wherein the weight ratio of the oil-soluble organic UV absorber (b) to polymer carrier (a) is greater than 50 parts UV absorber per 100 parts of carrier; and c) a surfactant selected from c1) a nonionic surfactant selected from c11) the condensation product of a C6 to C18 fatty alcohol or C6 to C18 fatty acid and a mono- or disaccharide; and c2) an anionic surfactant selected from c21) sulfosuccinates and sulfosuccinamates; c22) fatty alcoholates; and c23) mixtures of phosphoric acid esters and fatty alcohols having from 6 to 18, preferably from 8 to 10, carbon atoms. The aqueous polymer dispersions show unexpectedly high sunscreen effects and a positive skin feeling. They have excellent anti-pollen, ant-dust and anti-oxidant performances in sun screen compositions.
(FR) L'invention concerne une dispersion polymère aqueuse ayant une taille moyenne de particule inférieure à 1 000 nm, comprenant a) un support polymère préparé par polymérisation radicalaire en hétérophase d'au moins un monomère éthyléniquement insaturé en présence de b) un absorbeur UV organique soluble dans l'huile choisi dans la classe des dérivés de l'acide p-aminobenzoïque ; des dérivés de l'acide salicylique ; des dérivés de la benzophénone ; des dérivés du diphénylacrylate ; des dérivés du benzofurane ; des absorbeurs UV polymères, comprenant un ou plusieurs radicaux d'organosilicium ; des dérivés de l'acide cinnamique ; des dérivés du camphre ; des dérivés de la s-triazine ; des dérivés de la trianilino-striazine ; des anthranilates de menthyle ; et des dérivés du benzotriazole ; le rapport en poids de l'absorbeur UV organique soluble dans l'huile (b) à un support polymère (a) est supérieur à 50 parties d'absorbeur UV pour 100 parties de support ; et c) un tensioactif choisi parmi c1) un tensioactif non ionique choisi parmi c11) le produit de condensation d'un alcool gras en C6-C18 ou d'un acide gras en C6-C18 et d'un monosaccharide ou d'un disaccharide ; et c2) un tensioactif anionique choisi parmi c21) des sulfosuccinates et des sulfosuccinamates ; c22) des alcoolates gras ; et c23) des mélanges d'esters de l'acide phosphorique et d'alcools gras comprenant entre 6 et 18 atomes de carbone, de préférence entre 8 et 10 atomes de carbone. Les dispersions polymères aqueuses présentent des effets d'écran solaire étonnamment élevés et une sensation au toucher positive. Elles présentent d'excellentes performances anti-pollen, anti-poussière et anti-oxydant dans des compositions d'écran solaire.
