Historically, the first mentions of zinc sulfide being utilized as a pigment were approximately sixty years before the everyday use of lithopone. Originally, it was thought to be appropriate for coloring rubber. In England, a patent was granted for this process. Two decades after this, the focus shifted to zinc sulfide as a suitable pigment for paint. The year 1874 witnessed the patenting of a manufacturing process for a novel white pigment composed of zinc sulfide and barium sulfate. Dubbed Charlton white or Orr’s white enamel, this began a new era for white pigments.
Animal studies have shown that, when consumed as a food additive, titanium dioxide can induce intestinal inflammation.

Market Dynamics
- Both 28B301 and 30B311 are white pigments with high brightness and excellent covering power. They are commonly used in coatings, plastics, rubber, and paper industries. The main difference between these two grades lies in their particle size distribution. 28B301 has a smaller particle size, resulting in higher opacity and better dispersion. On the other hand, 30B311 has a larger particle size, which makes it more suitable for applications that require good rheological properties.
- Therefore, the most ideal treatment method for acid leaching slag is to selectively leaching zinc, allowing zinc to enter the leaching solution, and recovering and utilizing zinc to obtain valuable zinc-containing products such as lithopone products.
Since then, there has been a few animal studies suggesting titanium dioxide is connected to cancer. A 2017 study in Scientific Reports, for instance, found that rats with titanium dioxide in their diet had impaired immune systems, which could contribute to autoimmune diseases and colorectal cancer.
- The cost factor is another critical consideration for buyers
The availability of other white pigments poses a major challenge for the Lithopone market during the forecast period. Other alternatives to Lithopone include Zinc White, Titanium Dioxide, Calcium Carbonate, Blanc Fixe, and Barytes. The use of TiO2 has reduced the commercial significance of the Lithopone in the pigments industry.

Titanium dioxide is an inert earth mineral used as a thickening, opacifying, and sunscreen ingredient in cosmetics. It protects skin from UVA and UVB radiation and is considered non-risky in terms of of skin sensitivity. Because it is gentle, titanium dioxide is a great sunscreen active for sensitive, redness-prone skin. It’s great for use around the eyes, as it is highly unlikely to cause stinging.
- Moreover, the development of new technologies has expanded the applications of titanium dioxide beyond its traditional uses. For example, nanotechnology has enabled the creation of titanium dioxide nanoparticles with enhanced properties, such as improved UV protection and antibacterial activity. These nanoparticles are being used in a variety of products, including textiles, electronics, and healthcare products.

According to the EFSA's Expert Panel on Food Additives and Flavorings 2021 opinion regarding titanium dioxide, it could not rule out a concern for genotoxicity from ingestion of the material based on a perceived gap in data on this risk, which serves as the basis for current ban, said a March report on the decision.
- Titanium dioxide is a key ingredient in many products, including paint, sunscreen, and food coloring. As a result, there is a high demand for this versatile compound, leading to the need for reliable suppliers who can provide high-quality titanium dioxide.
Prof Matthew Wright, both a member of the FAF Panel and chair of EFSA’s working group on E 171, said: “Although the evidence for general toxic effects was not conclusive, on the basis of the new data and strengthened methods we could not rule out a concern for genotoxicity and consequently we could not establish a safe level for daily intake of the food additive.”

- Anatase, on the other hand, is a titanium dioxide form that exhibits higher photocatalytic activity and lower photocorrosion compared to rutile. It is commonly used in sunscreens, cosmetics, and water treatment due to its ability to absorb ultraviolet light and protect skin from harmful UV radiation. Anatase titanium dioxide is typically produced by the chloride process, which involves the chlorination of titanium ore to produce titanium tetrachloride Anatase titanium dioxide is typically produced by the chloride process, which involves the chlorination of titanium ore to produce titanium tetrachloride

Yet another study, this one published in 2006 by the International Agency for Research on Cancer said there was insufficient evidence to conclude that titanium dioxide causes cancer. However, the study also categorized the ingredient as a potential human carcinogen.
Some websites maintain titanium dioxide is inferior to zinc oxide, another mineral sunscreen ingredient whose core characteristics are similar to those of titanium dioxide. The reality is that titanium dioxide is a great broad-spectrum SPF ingredient and is widely used in all manner of sun-protection products. What gets confusing for some consumers is trying to decipher research that ranks sunscreen ingredients by a UV spectrum graph. By most standards, broad-spectrum coverage for sunscreen ingredients is defined as one that surpasses 360 nanometers (abbreviated as “nm” - how the sun’s rays are measured). Titanium dioxide exceeds this range of protection, but depending on whose research you read, it either performs as well as or slightly below zinc oxide.
Though the regulated use of titanium dioxide in food products is legal in the U.S. and Canada, it's banned in some other countries, notably throughout Europe. In May 2021, the European Food Safety Authority announced that titanium dioxide can no longer be considered safe as a food additive.
According to Procurement Resource, the prices of titanium dioxide are expected to showcase mixed sentiments. With trade and supply-chain normalization, the automotive and construction sectors are estimated to improve their global performance, thus affecting the prices positively.
