Titanium IV Oxide, commonly known as Rutile Titanium Dioxide (TiO2), is a highly valued compound with an array of applications across various industries due to its exceptional properties. It is a naturally occurring oxide of titanium, predominantly found in the mineral rutile, which is renowned for its high refractive index, excellent opacity, and strong UV resistance. This makes TiO2 a vital ingredient in products ranging from paints and coatings to cosmetics and sunscreen lotions.

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.
