Lithopone is an inorganic white pigment, obtained from co-precipitation of Zinc sulfide (ZnS) and Barium sulfate (BaSO4). Titanium Dioxide (TiO2) has replaced Lithopone as a white pigment in majority applications as TiO2 is more durable. However, it is much cheaper than TiO2 and has advantages such as low binder requirement and good dispensability. As a white pigment, it can improve the substrate's weather resistance, and improve the fungicidal properties of paint formulations. Some of the major applications of Lithopone include manufacturing of paint pigments, plastic & rubber products, paper, printing inks, cosmetics, and leather & linoleum products. It is commercially available under names such as pigment white 5, Barium zinc sulfate sulfide, Becton White, C.I. 77115, Charlton White, Enamel White, and Zincolith. On the basis of content of ZnS, Lithopone is available at 28%-30% Lithopone and 60% Lithopone.

The manufacturing process of emulsion latex paints involves combining polymer emulsions with pigments, additives, and water. Rutile TiO2 serves as the predominant pigment due to its superior light scattering abilities. Its small, uniform particle size ensures maximum surface area coverage, leading to a more vibrant and durable finish. Moreover, the rutile form exhibits good weather resistance and does not readily break down under exposure to UV light, ensuring that the paint maintains its color and integrity over extended periods.
