Typically, this mineral is produced in two forms. The primary type is pigment-grade titanium dioxide, which utilizes its pigment to provide a look of sensitivity and brightness.

Studies have been carried out with both emulsion paints and powder paints, both with clear results on how the use of lithopone supplier 30% reduces the appearance of algae in the paint once it has been applied (see photos). 

Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors the pigment itself can vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant may be used, such as a small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.
