Lithopone, C.I. Pigment White 5, is a mixture of inorganic compounds, widely used as a white pigment powder. It is composed of a mixture of barium sulfate and zinc sulfide. These insoluble compounds blend well with organic compounds and confer opacity. It was made popular by the cheap production costs, greater coverage. Related white pigments include titanium dioxide, zinc oxide (zinc white), zinc sulfide, and white lead.^[1]

2. What foods contain titanium dioxide?

Yes. According to the FDA and other regulatory agencies globally, “titanium dioxide may be safely used for coloring foods”. Titanium dioxide is safe to use, and the FDA provides strict guidance on how much can be used in food. The amount of food-grade titanium dioxide that is used is extremely small; the FDA has set a limit of 1 percent titanium dioxide for food. There is currently no indication of a health risk at this level of exposure through the diet.
