SUNSCREEN COMPOSITIONS COMPRISING A MIXTURE OF TITANIUM AND/OR ZINC OXIDE PARTICLES, METHOD FOR PREPARING THE SAME AND USE THEREOF

摘要

A sunscreen composition containing a synergic mixture of titanium and/or zinc oxide particles, characterised in that said particles are incorporated in paste-forming oils and/or esters and/or fatty alcohols and/or ethers selected so as to provide a wetting point of the incorporated titanium oxide particles and of the incorporated zinc oxide particles lower than about 5 and a flow point of said incorporated particles lower than about 30. The invention also provides a method for preparing said composition and the use thereof for protecting the skin against ultraviolet radiation and for maintaining the monocrystalline dispersion of minerals in the formulation and on the skin.
