This precipitate is not suitable for a pigment until it is filtered, dried, crushed, heated to a high temperature and quenched in cold water. The second heating in a muffle furnace at 725 °C produces crystals of the right optical size.
Moreover, a 2019 study noted that food-grade titanium dioxide was larger and not nanoparticles. Hence, the authors concluded that any titanium dioxide in food is absorbed poorly, posing no risk to human health (3Trusted Source).
The ingredient in question? Titanium dioxide.

Lithopone B301, Lithopone B311 powder, C.I. Pigment White 5, is a mixture of inorganic compounds, widely utilized as a white pigment. It is composed of a mixture of barium sulfate and zinc sulfide. These insoluble compounds blend well with organic compounds and confer opacity. Lithopone B301, Lithopone B311 powder is famous for the cheap production costs, greater coverage. Related white pigments include titanium dioxide, zinc oxide (zinc white), and zinc sulfide
CSPI says it might reconsider its rating if specifications for food-grade titanium dioxide in the U.S. are updated to ensure nanoparticles are minimized, and new studies are conducted to assess its capacity to cause cancer or other health problems.
