There is some evidence that ingested titanium dioxide does not completely exit the body. A 2015 review of animal studies and a few human studies suggests titanium dioxide can get absorbed into the bloodstream and expose other organs to damage.
3. Regulatory Compliance It is crucial for suppliers to adhere to industry regulations, especially in sectors like food, pharmaceuticals, and cosmetics. Reliable suppliers will ensure their products meet relevant regulatory standards, providing proper documentation and certifications.
- The first step in the pigment production process often involves mining or sourcing the raw materials. Natural pigments are extracted from the earth, while synthetic pigments are synthesized in laboratories using complex chemical reactions. Once obtained, these materials undergo purification to remove impurities, ensuring the highest quality and consistency.
In 2021, the European Food Safety Authority concluded that titanium dioxide is no longer safe in foods due to the same concerns over nanoparticles. As a result, titanium dioxide is now banned as a food additive in the EU. Although studies have shown that the absorption of ingested titanium dioxide is low, evidence suggests that titanium dioxide nanoparticles can accumulate in the body over time. Health Canada deemed it safe in 2022 but noted concerns. Unlike their European counterparts, Canadian officials did not consider studies performed with titanium dioxide nanoparticles alone.

Founded in 1902 by Henrick J. Krebs, Krebs Pigments and Chemical Company produced lithopone, a widely used white paint pigment also manufactured by DuPont. But Krebs' company had another asset of special interest to DuPont. ...
For research published in 2022 study in the journal Food and Chemical Toxicology, scientists examined “the genotoxicity and the intracellular reactive oxygen species induction by physiologically relevant concentrations of three different TiO2 nanomaterials in Caco-2 and HT29-MTX-E12 intestinal cells, while considering the potential influence of the digestion process in the NMs’ physiochemical characteristics.” They found a “DNA-damaging effect dependent on the nanomaterial,” along with the micronucleus assay suggesting “effects on chromosomal integrity, an indicator of cancer risk, in the HT29-MTX-E12 cells, for all the tested TiO2 nanomaterials.” Researchers concluded that the results showcase “evidence of concern” regarding titanium dioxide used as a food additive.
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.
Buff percentage refers to the amount of uncoated or partially coated titanium dioxide particles in a product. A higher buff percentage generally indicates a lower level of coating, which can impact the overall performance of the titanium dioxide. Manufacturers must carefully control this percentage to ensure that their product meets the specific requirements of their customers.
