COMPOSITE ULTRAVIOLET BLOCKING AGENT, COSMETIC AND RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a composite ultraviolet blocking agent preventing the harmful effects of ultraviolet radiation over the wide wavelength range of UV-A and UV-B and, at the same time, securing high transparency, and to provide cosmetics and resin compositions each containing the agent. SOLUTION: The composite ultraviolet blocking agent comprises lepidochrocite-type plate-like titanic acid crystal particles and cerium oxide-based crystal particles coated on the surface of the lepidochrocite-type plate-like titanic acid crystal particles, wherein the cerium oxide-based crystal particles account for 20-90 mass% of the total of the lepidochrocite-type plate-like titanic acid crystal particles and the cerium oxide-based crystal particles.
