There's also evidence that inhaling titanium dioxide particles can be dangerous. That's mainly a concern for industrial workers. In places where it's produced, or where it's used to make other products, workers can breathe it in as a dust. The Occupational Health and Safety Administration has exposure standards manufacturers must meet.

Lomon, one of the leading titanium dioxide manufacturers in China, produces the R996 grade titanium dioxide with purity levels exceeding 99%. This high purity ensures that the pigment provides excellent hiding power and color retention in paints, making it a popular choice for the paint industry.

Specification:

Three aspects determine the performance of titanium dioxide as pigment and UV absorber.

1. Properties: white powder, a mixture of zinc sulfide and barium sulfate.

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.

Australian researchers examined how titanium dioxide as a food additive affected gut microbiota in mice by orally administering it in drinking water. The study, published in the journal Frontiers in Nutrition in 2019, found the treatment could “alter the release of bacterial metabolites in vivo and affect the spatial distribution of commensal bacteria in vitro by promoting biofilm formation. We also found reduced expression of the colonic mucin 2 gene, a key component of the intestinal mucus layer, and increased expression of the beta defensin gene, indicating that titanium dioxide significantly impacts gut homeostasis.” The changes were then linked to colonic inflammation, along with a higher expression of inflammatory cytokines, which are signal proteins that help with regulation. The researchers concluded that titanium dioxide “impairs gut homeostasis which may in turn prime the host for disease development.”

Still many experts say the body of research does not support the current health concerns being expressed about titanium dioxide.

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.

You may be taking a second look at your favorite candy after hearing this week's news about titanium dioxide. Recently, a lawsuit was filed against Mars, Inc. based on claims that the manufacturer's popular Skittles candy is unfit for human consumption. The class-action lawsuit, filed in U.S. District Court for the Northern District of California in mid-July, alleged that the candy contained heightened levels of a known toxin called titanium dioxide — a food additive that the company previously pledged to phase out from their products in 2016, according to the Center for Food Safety.

Panzhihua Dongfang TiO2 manufacturer has 28 patents related to titanium dioxide production by sulfuric acid method, 3 research results, and 5 registered trademarks. Excellent quality, excellent covering power, excellent system dispersion, good whiteness, high brightness, and low oil absorption. The company’s products are exported to more than 40 countries and regions in the world, and the export ratio is nearly 40%. It is the second largest exporter in Panzhihua City after Panzhihua Iron and Steel.

What is titanium dioxide?

The produced barium sulfide enters the leacher, and the temperature is controlled above 65°C to obtain a barium sulfide content of 70%, and then enters the clarification barrel, add zinc sulfate for reaction after clarification, control the zinc sulfate content to be greater than 28%, pH=8~9, and obtain a mixture of barium sulfate and zinc sulfide with a density of 1.296~1.357 g/cm3.
