ORGANIC-INORGANIC COMPOSITE POWDER FOR BLOCKING UV AND THE COSMETIC COMPOSITION CONTAINING THEREOF

摘要

PURPOSE: Organic and inorganic composite powder for blocking UV rays and a cosmetic composition containing the same are provided to ensure excellent UV protection ability, dispersion property, softness, and a moisturizing effect. CONSTITUTION: Organic and/or inorganic composite powder for blocking UV rays is prepared by surface-treating inorganic powder with one or more phospholipids selected from 2-methacryloyloxyethyl phosphorylcholine and 2-methacryloyloxyethyl phosphatidylcholine. The inorganic powder is selected among titanium oxide and zinc oxide. The inorganic powder contains 0.1-8% of phospholipid. A cosmetic composition for blocking UV rays contains 0.1-25wt% of organic and inorganic composite powder.
