The manufacturing process of lithopone involves several steps, including sulfide precipitation, grinding, classification, and packaging. During the sulfide precipitation stage, zinc sulfide and barium sulfate are reacted in an aqueous solution under controlled conditions to form a precipitate of lithopone. The precipitate is then washed, dried, and ground to the desired particle size distribution. Finally, the ground pigment is classified to remove any oversized or undersized particles and packaged for storage and transportation.

The safety of food-grade titanium dioxide, or E171, lies in its ultrafine particle size. These particles are too small to be absorbed by the human body, passing through the digestive system without causing harm. Extensive research has been conducted to confirm this, with studies showing no evidence of genotoxicity or carcinogenicity. However, recent concerns about potential effects from nano-sized particles have led to ongoing evaluations However, recent concerns about potential effects from nano-sized particles have led to ongoing evaluations However, recent concerns about potential effects from nano-sized particles have led to ongoing evaluations However, recent concerns about potential effects from nano-sized particles have led to ongoing evaluationsfood safe titanium dioxide.
