The cytotoxic effect was tested through the colorimetric assay employing 3′-[1-[(phenylamino) -carbonyl]−3,4-tetrazolium]-bis(4‑methoxy-6-nitro) benzene-sulfonic acid hydrate (XTT) by reading the absorbance at 490 nm after 3 h of incubation post treatment [28]. The absorbance is proportional to the metabolic rate of viable (live) cells.

Among the raw materials for coating production, titanium dioxide is more ideal, followed by lithopone. The covering power of lithopone is only that of titanium dioxide, and the price of lithopone is much lower than that of titanium dioxide, so lithopone still occupies a large market share.

We use titanium dioxide as a colourant in some home care products, including in laundry detergents, dishwasher tablets and toilet blocks.

In the manufacturing industry, sometimes many products require coloring, and the ideal coloring material is lithopone. This is a product manufactured through chemical methods. It is a mixture of barium sulfate and zinc sulfide. When the product contains more zinc sulfide, its effect will be better, that is, the coloring ability will be more stable. If you want to buy high-quality lithopone, you have to understand its properties and characteristics. Today’s article will give you a detailed understanding of lithopone.
