Below 10% substitution, 1 kg of TiO2 should be replaced by 1 kg of Lithopone 30%.  

Titanium dioxide is predominantly used as a pigment in products such as paints, coatings, plastics, food, cosmetics, and paper. The ability of TiO2 to scatter light and provide a white color makes it an essential ingredient in achieving high-quality finishes in these applications. However, the production of titanium dioxide can be complex and costly, given that it involves raw materials such as ilmenite and rutile, as well as advanced processing technologies. Manufacturers are continuously striving to optimize costs without compromising quality, making the search for affordable suppliers a top priority for many businesses.

Titanium dioxide comes in the form of a white powder and is sometimes used in cosmetics to adjust a color to a lighter shade. This is also why it can produce a white cast.
