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.

Regardless of the technique chosen, manufacturers must follow strict protocols to ensure the accuracy and reliability of their results. This includes proper sample preparation, calibration of instruments, and validation of analytical methods. By following these guidelines, manufacturers can confidently determine the level of sulphate in their TiO2 products and ensure that they meet the required standards for their intended applications.
