Abstract
A process for making metal oxide hydrophobic by coating the metal oxide with a silicone polymer is disclosed. The hydrophobic metal oxide is prepared by contacting the metal oxide with a reactive silicone compound and then in a subsequent step the coated metal oxide is heated to 40.degree. to 100.degree. C. for between 1 and 10 hours. The resulting metal oxide is hydrophobic, non-reactive, not affected by water and can be applied to the skin for protection from ultraviolet light of the sun.
