Abstract
Abstract An anhydrous, three-phase powder-like cosmetic product comprising a) 10 to 60 weight % of a gel phase comprising ethylene/acrylate copolymer and an ester having the formula ROCOR, wherein R is an alcohol or fatty alcohol having a molecular weight of 60-400 and R 1 is a fatty acid having a molecular weight of 120-500; b) 30 to 60 weight % of a powder phase comprising filler, color, preservative and substantially spherical silica particles having an average particle size of less than 15 microns; and c) 10 to 20 weight % of an oil phase comprising cosmetically acceptable alcohol esters of fatty acids.
