摘要
The particulate metal oxide has a metal oxide core and a coating layer containing an inorganic material and (i) a quaternary silane coupling agent, and / or (ii) a silane coupling agent and a hydrophobic agent. Preferred materials are titanium dioxide core particles, amino organosilane coupling agents and fatty acid hydrophobicizing agents. Particulate metal oxides are suitable for use in forming dispersions, and the particles and dispersions can be used in end use sunscreen compositions that are transparent and exhibit effective UV absorption properties, reduced photoactivity, and / or improved skin feel. .
