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.

Modern production facilities employ state-of-the-art technologies to ensure particle size distribution is optimal, which is crucial for the pigment's performance in end-use applications. Advanced filtration systems remove impurities, ensuring that the final product meets the highest purity levels. Additionally, manufacturers pay close attention to environmental concerns by implementing waste management strategies to minimize any negative impact during the production process.
