A review published in 2022 in the journal NanoImpact evaluated the latest research related to genotoxic effects of titanium dioxide through in vivo studies and in vitro cell tests. Researchers summarized the results by stating TiO2 nanoparticles “could induce genotoxicity prior to cytotoxicity,” and “are likely to be genotoxic to humans.”

Finally, it's important to consider the global trends impacting the pigment industry as a whole. Environmental regulations, technological advancements, and sustainable practices are increasingly becoming part of the conversation. Suppliers that prioritize eco-friendly production methods or offer biodegradable alternatives may appeal to buyers willing to pay a higher price for sustainably sourced materials.

Le lithopone a été découvert dans les années 1870 par DuPont. Il a été produit par la Krebs Pigments and Chemical Company, entre autres¹. Il se faisait en différents grades, en fonction de la teneur en sulfure de zinc. Les qualités « bronze » et « or » contenaient 40 à 50 % de sulfure de zinc, ce qui les rendaient particulièrement couvrantes². Bien que ce pigment ait atteint son pic de popularité autour de 1920, il s'en produisait encore annuellement plus de 220 000 tonnes en 1990. Il est principalement utilisé dans les peintures, les pâtes et les plastiques³.

According to data released by the China Coatings Industry Association, the total production of China's coatings industry has increased from 12.72 million tons in 2012 to 24.388 million tons in 2019, with a compound annual growth rate of 9.7%. Coatings, as an intermediate commodity, are closely related to downstream consumer markets such as the automotive industry, real estate, infrastructure, and home furnishings.

The global Lithopone market was valued at $169.8 million in 2019, and is projected to reach $218.6 million by 2027, growing at a CAGR of 3.30% from 2020 to 2027.

Lithopone is a white pigment composed of a mixture of barium sulfate (BaSO4) and zinc sulfide (ZnS). It is commonly used in the production of paints, plastics, rubber, and various other industrial applications. As such, manufacturers and distributors often provide Material Safety Data Sheets (MSDS) to ensure the safe handling and use of the product.
