In addition to its optical properties, Lithopone B301 also offers good chemical and weather resistance. This means that products formulated with Lithopone B301 will maintain their color and performance even when exposed to harsh environmental conditions. This makes it a reliable and durable choice for a wide range of applications.
JECFA previously assessed titanium dioxide at its 13th meeting, at which time the expert committee assigned a “not specified” ADI for the additive due to an absence of significant absorption and a lack of toxicological effects in the available experimental animal and human studies. Since its original evaluation by JECFA, titanium dioxide has become a public point of contention, with its ban being introduced (and then subsequently withdrawn) in California legislation in 2023, a legal battle playing out in the EU over the additive’s ban and classification as a carcinogen in 2022, and the European Food Safety Authority (EFSA) calling titanium dioxide unsafe. However, supporters of titanium dioxide say that claims about its dangers are founded in unreliable studies, and some recent research has supported its safety as a food additive.
The factories where lithopone is produced adhere to strict quality control measures to ensure that the pigment meets the required specifications for different applications
lithopone 28~30% factories. This includes testing the purity, particle size, and brightness of the pigment, as well as conducting performance tests to assess its coverage and weather resistance.
We’re most often exposed to E171 through the foods we ingest. We find E171 in many food products, like popsicles, ice cream, gum, and more. Another way we ingest E171 is through pharmaceutical drugs. Many pills and capsules contain E171 as an inactive ingredient.
In the sulfate process, the ore is first crushed and then heated with sulfuric acid. This reaction produces titanyl sulfate, which is subsequently treated with water to form titanium dioxide. The resulting precipitate is filtered, washed, dried, and calcined to produce the final product. One of the drawbacks of this method is the large amount of waste acid generated, which requires careful disposal to minimize environmental impact.
The production of titanium dioxide in China is mainly concentrated in the eastern provinces of Shandong, Jiangsu, and Henan. These provinces are home to numerous titanium dioxide manufacturers, both large and small, that cater to the domestic and international markets. The industry has been growing rapidly in recent years due to the increasing demand for titanium dioxide worldwide.
As a food additive, titanium dioxide and its nanoparticles in particular have been associated with DNA damage and cell mutations, which in turn, have potential to cause cancer. When used as a food coloring, it is known as E171.
How we’re exposed to an ingredient matters greatly in terms of our long-term health.
Research shows that inhaling titanium dioxide particles in significant quantities over time can cause adverse health outcomes. Unless you work in an industrial setting, inhaling substantial amounts of titanium dioxide is highly unlikely.
