Following a request for assessment in 2020 by the EU, the European Food Safety Authority (EFSA) assessed E171, particularly for its genotoxicity. In 2022, the agency deemed the food additive no longer safe for use.
Lithopone, also called zinc-barium white, is a very stable network molecular structure formed by the reaction of zinc sulfate and barium sulfide and calcined at high temperature. Lithopone is a white powder that is non-toxic and non-corrosive. It is insoluble in water and does not interact with hydrogen sulfide and alkali. It dissolves with acid and produces hydrogen sulfide gas.
