Due to its low binder requirement, lithopone provides paints with good flow and application properties. In the plastic processing industry, it is added to plastics to increase the plastic product’s UV tolerance, thus increasing its outdoor life. In the leather industry, it is one of the sulfide-based white pigments. It is also used in the production of linoleum floorings.
The FDA first approved the use of titanium dioxide in food in 1966, following its 1960 removal (along with the removal of other color additives) from the agency's original Generally Recognized as Safe list.

As a widely used substance with multiple applications, research is being carried out to improve the production process to reduce the levels of chemicals used and waste produced, and to recycle any by-products.
