Rutile, the most common form of titanium dioxide, is a reddish-brown pigment with a high refractive index and excellent weathering resistance. It is mainly used in paints, coatings, plastics, and paper industries due to its ability to provide excellent whiteness, opacity, and UV protection. Rutile titanium dioxide is typically produced by the sulfate process, which involves the reaction of titanium ore with sulfuric acid to produce titanium sulfate. The resulting solution is then treated with ammonia to precipitate titanium hydroxide, which is subsequently calcined at high temperatures to obtain rutile titanium dioxide.
FAQ – EFSA 2021 safety assessment of titanium dioxide (E171)
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.”
