Materials

Lithopone, a chemical compound with a rich history, emerges as a vital substance in various industries. Comprising barium sulfate and zinc sulfide, this compound boasts unique properties that make it a popular choice in applications such as paints, inks, and plastics. Recognized for its exceptional opacity and brightness, lithopone significantly enhances the covering power of materials in which it is incorporated. Its inert nature and resistance to atmospheric influences contribute to its longevity in diverse formulations. As a white pigment, lithopone plays a pivotal role in achieving vibrant and enduring colors across a spectrum of products, marking it as a cornerstone in the realm of chemical compounds.

While the conclusions of the EU expert panel were considered in this report, Health Canada's Food Directorate conducted its own comprehensive review of the available science. This included evaluating new scientific data that addressed some of the uncertainties identified by the EU expert panel and were not available at the time of their review.    

LITHOPONE

Abstract

History

In a study published in the journal Toxicology, researchers examined the effects of exposing human colon cancer cell line (HTC116) titanium dioxide food additives in vitro. “In the absence of cytotoxicity, E171 was accumulated in the cells after 24 hours of exposure, increasing granularity and reactive oxygen species, inducing alterations in the molecular pattern of nucleic acids and lipids, and causing nuclei enlargement, DNA damage and tubulin depolymerization,” the scientists wrote. Researchers removed the additive from the culture, then examined the results 48 hours later. They found, “The removal of E171 was unable to revert the alterations found after 24 h of exposure in colon cells. In conclusion, exposure to E171 causes alterations that cannot be reverted after 48 h if E171 is removed from colon cells.”

One of the key advantages of using titanium dioxide in rubber is its ability to enhance the whiteness and brightness of rubber products. This is especially important in applications where aesthetic appeal is a priority, such as in the manufacturing of white or light-colored rubber goods. The high opacity of titanium dioxide allows for better hiding power, ensuring a uniform and attractive finish on rubber surfaces.

Faber argued there hasn't been enough change in these federal regulations in the decades following the FDA's approval of titanium dioxide – especially as others increasingly point to potential health consequences.

There are many ways we’re exposed to titanium dioxide in our everyday life. Below are the most common ways we encounter titanium dioxide.
