Lithopone, a white pigment composed of a mixture of zinc sulfide and barium sulfate, has become an indispensable ingredient in the paint industry. Its unique properties, including excellent opacity, high brightness, and resistance to weathering, make it highly valued among paint manufacturers. As the demand for sustainable and efficient paint products grows, the role of lithopone and its suppliers has become more critical than ever.
The European Food Safety Authority (EFSA) has concluded that titanium oxide should not be considered safe as a food additive, due to uncertainties about possible inflammation and neurotoxicity (9Trusted Source).
Key benefits for stakeholders
In response to the allegations, Justin Comes, vice president of research and development at Mars Wrigley North America, told Health that safety is of paramount importance to Mars Wrigley. While we do not comment on pending litigation, all Mars Wrigley ingredients are safe and manufactured in compliance with strict quality and safety requirements established by food safety regulators, including the FDA.
As for titanium dioxide, the FDA approved titanium dioxide for use as a food additive in 1966. The last time the agency reviewed the additive’s safety, according to the Guardian, was in 1973.
Lithopone B301, Lithopone B311 powder, brilliant white pigment used in paints, inks, leather, paper, linoleum, and face powder. It was developed in the 1870s as a substitute or supplement for lead carbonate (white lead), to overcome its drawbacks of toxicity, poor weathering, and darkening in atmospheres that contain sulfur compounds. Lithopone B301, Lithopone B311 powder is an insoluble mixture of barium sulfate and zinc sulfide that precipitates upon mixing solutions of barium sulfide and zinc sulfate. The precipitate is recovered by filtration, then calcined (roasted) at temperatures above 600° C (1,112° F). Although Lithopone B301, Lithopone B311 powder has been replaced in many applications by titanium dioxide, it is still widely used in a number of products, such as water paints.
One of the key factors that influence the quality of lithopone is its raw material composition. We carefully select high-quality barium sulfate and zinc sulfide as the main components, which are essential for the formation of the desired crystal structure and chemical properties of lithopone. To further enhance the performance of lithopone, we also add certain additives during the production process. Chinese Tio2 manufacturers have been able to achieve economies of scale, allowing them to offer competitive prices in the international market. Their advanced refining technologies and capacity expansion initiatives have further consolidated their position. Companies like Tianda Chemical, Zhejiang Huayi, and Anhui Annada Titanium Industry Co., Ltd. are among the leading producers contributing to this growth. In the plastics industry, titanium dioxide is used as a filler to improve the strength, durability, and whiteness of the final product. It also helps to protect plastics from ultraviolet (UV) light, which can cause degradation over time. As a result, titanium dioxide-filled plastics are commonly used in applications such as automotive parts, household appliances, and outdoor furniture.Some small test-tube research has shown that these nanoparticles are absorbed by intestinal cells and may lead to oxidative stress and cancer growth. However, other research has found limited to no effects (13Trusted Source, 14Trusted Source, 15Trusted Source).
In terms of production, China is the largest producer of both calcium carbonate and titanium dioxide in the world. The country has abundant reserves of both minerals and a well-developed mining and processing industryTitanium dioxide market trend analysis and prediction
