However, since it’s photosensitive — meaning it can stimulate free radical production — it’s usually coated in silica or alumina to prevent potential cell damage without reducing its UV-protective properties (7Trusted Source).
- After beneficiation, the barium sulfate is then processed into superfine particles

We even use titanium dioxide when brushing our teeth as it’s found in many toothpastes.
Magnesium occurs in seawater and in ores such as dolomite (CaCO 3 MgCO 3), magnesite (MgCO 3), and carnallite (MgCl 2 KCl 6H 2O).

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 Lithopone B301, Lithopone B311 powder itself may vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant might be used, like 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.

What is the FDA limit for titanium dioxide?
Some food products will include titanium dioxide on their nutrition label. But again, it can be hard to tell for those who don't list the ingredient.



According to the American Chemistry Council, titanium dioxide (TiO2) is an inorganic substance that's used as a white powder in a variety of industrial and consumer goods, including in sunscreen, cosmetics, toothpaste, paint, plastics, food and more.
In some studies, E171 was given to animals in drinking water without the stabilizers that keep E171 suspended in the liquid. Without stabilizers, E171 can settle and prevent the ingredient from combining with surrounding ingredients.


But what is titanium dioxide, exactly? Here's what you need to know about this popular food additive — including what products it's used in and whether it's safe to consume.
