Abstract
The present invention provides a novel manufacturing process for producing a high surface area USP grade titanium dioxide in the nano-anatase form. In a manufacturing method aspect of the present invention, a process of producing a high surface area USP grade TiOnano-anatase base is provided. The method involves steps of: a) phosphorus doping of the titanium hydrate obtained in hydrolysis of a titanium compound; b) drying and calcination of the doped paste, thereby producing a high surface area USP grade titanium dioxide in the anatase crystal form with nano-particles suitable for UV screens and cosmetics.
