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.

One of the key responsibilities of chemical pigment manufacturers is to develop pigments that are safe, non-toxic, and environmentally friendly. Today, there is a growing demand for greener and more sustainable products, and chemical pigment manufacturers need to keep up with these trends by using eco-friendly raw materials and production processes. This includes reducing the use of harmful chemicals and promoting recycling and waste management practices.
