Abstract
A process for protecting skin with a hydrophobized titanium dioxide is disclosed. The silicone composition is prepared by the reaction of a reactive alkoxy silicone which is applied to the titanium dioxide then in a subsequent step the coated titanium dioxide is heated to 40 to 100 C. for between 1 and 10 hours for the reaction to occur. The resulting titanium dioxide which is hydrophobic, non-reactive, and not affected by water, is applied to the skin for protection from Ultra violet light of the sun.
