Les pouvoirs couvrant et éclaircissant du lithopone normal sont supérieurs à ceux de la céruse et de l'oxyde de zinc, mais inférieurs au Dioxyde de Titane pur, étant le meilleur blanc sous tout rapport. C'est le sulfure de zinc qui, avec son indice de réfraction de 2,37, est l’élément opaque ; le 2nd composé, le sulfate de baryum, joue un rôle de diluant minéral et favorise l'efficacité de la diffusion du premier.
In 2022, a year after the EFSA recommended against the use of E171, the Food Standards Australia New Zealand (FSANZ) conducted its own reassessment of titanium dioxide as a food additive. The agency concluded that titanium dioxide was indeed safe to use as a food additive. The United Kingdom and Canada came to similar conclusions.
In June 2022, Health Canada weighed in on the debate, releasing a report on the safety of titanium dioxide. Their expert panel reviewed toxicity studies, including ones involving genetic damage. The expert panel found that previous studies used different forms and properties of titanium dioxide and deliberately broke the material into smaller particles than what you would normally see in food.
Lithopone B301, Lithopone B311 powder is widely used in coatings, printing ink, rubber, plastic industry, etc.
In order to achieve the same solids content, the larger filler and the binder should be reduced if necessary.
