Surface-modified, structurally modified titanium dioxides

摘要

A surface modified, structurally modified titanium dioxide or titanium dioxide mixed oxide, is prepared by thermal decomposition. Independent claims are included for the following: (1) manufacture of surface modified structurally modified titanium dioxide or titanium dioxide mixed oxide by using a ball mill and optionally post mill; (2) use of surface modified structurally modified titanium dioxide for sunscreen formulation; and (3) sunscreen formulation containing the surface modified, structurally modified titanium dioxide or mixed oxide.
