This article reviews the uses, benefits, and safety of titanium dioxide.

Barium sulfide is produced by carbothermic reduction of barium sulfate. Zinc sulfate is obtained from a variety of zinc products, often waste, by treatment with sulfuric acid.

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.

① Coatings: The downstream demand structure of domestic and overseas titanium dioxide is similar. Coatings are the largest application fields, accounting for 61% of the consumption. Among the four components of paint products, namely resin, pigments and fillers, solvents and additives, titanium dioxide accounts for 10% to 25% of the total cost, accounting for more than 90% of the total amount of pigments and fillers, and more than 95% of the total amount of white pigments.

Product Name: Lithopone

The ROS seemed to be endlessly produced by P25TiO₂NPs upon irradiation, since the values detected after 6 h are similar to the ones after 3 h. However, the amount of vitamin B2 in the surface of the NPs proved to be enough to decrease the ROS detected even after 6 h. Statistical analysis showed a significant difference between C and A. p < 0.05

Below 20% substitution, it is recommended to replace 1 kg of TiO2 with 1 kg of Lithopone.  

EU ban on titanium dioxide

CSPI’s Chemical Cuisine is the web’s definitive rating of the chemicals used to preserve foods and affect their taste, texture, or appearance. Besides titanium dioxide, the group recommends avoiding artificial sweeteners like aspartame, acesulfame potassium, and sucralose, as well as synthetic food dyes like Yellow 5 and Red 3. CSPI and others have recently asked the Food and Drug Administration to ban the latter dye in foods and ingested drugs because the FDA has already determined that it is a carcinogen unsafe for use in cosmetics.

Used for coloring paint, ink, rubber, etc. Inorganic white pigments are widely used as white pigments in plastics such as polyolefin, vinyl resin, ABS resin, polystyrene, polycarbonate, nylon and polyformaldehyde, as well as paints and inks. It is less effective in polyurethane and amino resins, and less suitable in fluoroplastics. It is also used for coloring rubber products, papermaking, varnished cloth, oilcloth, leather, watercolor paints, paper, enamel, etc. Used as an adhesive in the production of electric beads.

For years scientists have raised concerns about the potential toxicity of titanium dioxide.
