- China, with its abundant raw material resources and advanced manufacturing capabilities, has emerged as a major lithopone pigment manufacturer, catering to both domestic and international markets. Other countries, such as India and the United States, also contribute significantly to the global supply chain, ensuring a steady flow of this vital pigment.
- 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.
In a study published in the journal Food and Chemical Toxicology in 2016, researchers investigated whether titanium dioxide exposure led to an increase in colorectal tumor creation in mice by using a colitis associated cancer model. By measuring tumor progression markers, the researchers found that mice given titanium dioxide experienced enhanced tumor formation in the distal colon. There was also a decrease of cells that act as a protective barrier in the colon. The researchers wrote: “These results suggest that E171 could worsen pre-existent intestinal diseases.”

Production[edit]
The most common foods containing titanium dioxide are chewing gum, candies, pastries, chocolates, coffee creamers, and cake decorations (1Trusted Source, 3Trusted Source).
It should also be considered that due to the low pH in the stomach, the increased dissolution of the TiO2 particles may increase its bioavailability and may facilitate the entry of titanium ions into the blood circulation. Despite the relatively large consumption of TiO2 as a food additive, no studies on the effect of pH on its absorption and bioavailability have been found in the literature. This can be attributed to a general belief that TiO2is completely insoluble. However, this is not completely true, as TiO2 particles show a certain degree of solubility.
In a small study published in the European Journal of Nutrition in 2020, researchers examined the effects of several food additives, including titanium dioxide, along with artificial sweeteners and cleaning products by testing the fecal samples of 13 people. Titanium dioxide was among the samples that “induced significant shifts in microbiome community structure.” The growth of the bacterium species belonging to C. leptum, which has been shown to decrease in patients with inflammatory bowel disease, “significantly decreased in the presence of … titanium dioxide” among other additives and sweeteners tested.

Topical Exposure
Further outstanding properties of Lithopone are its high lightness, neutral white colour and its diffuse reflectance in the near UV range.
The scattering efficiency of pigment particles in a system is governed by two key properties.
