Title (EN) COSMETIC FORMULATIONS COMPRISING ZnO NANOPARTICLES
(FR) PREPARATIONS COSMETIQUES CONTENANT DES NANOPARTICULES DE ZNO
Abstract: front page image
(EN)The present invention relates to the formation of surface treated zinc oxide and titania particles, and in particular zinc oxide and titania nanoparticles, with a siloxane star-graft copolymer coating, comprising a looped and/or linear polymeric structure on a star-graft copolymer coating, on a particle surface to control the interfacial surface interactions between the particle and the oil phase of the cosmetic skin formulation.
(FR)La présente invention concerne la formation de particules de titane et d'oxyde de zinc traitées en surface et, notamment, des nanoparticules de titane et d'oxyde de zinc, avec un revêtement copolymère de greffe en étoile de siloxane, contenant une structure polymère en boucle et/ou linéaire sur un revêtement copolymère de greffe en étoile, sur une surface particulaire de manière à réguler les interactions superficielles interfaciales entre la particule et la phase huileuse de la préparation cutanée cosmétique.
