Abstract

The present invention is related to hydrophilic silicone powders and the methods to prepare the same that contain 1-30 mol % of units selected from a group consisting of (a) partially hydrolyzed silsesquioxane containing one hydroxyl group (T2) and silica (Q3), (b) partially hydrolyzed silsesquioxane containing two hydroxyl groups (T1) and silica (Q3), (c) silica containing three hydroxyl groups (Q1), hydrolyzed silicone containing siloxane (D1), and mixtures thereof, and hydrophilic silicone powders consisting of core described above and shells composed of silica, and/or titanium dioxide. The particles are useful as ingredients for cosmetics and emulsions because they have good heat resistance, good touching feeling, and readily disperse in water due to their hydrophilic nature and high water absorbency.
