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.”

In addition to hiding power, titanium dioxide also plays a vital role in enhancing the durability of paints. It acts as a barrier, protecting the walls from external elements such as UV radiation, moisture and pollutants. Titanium dioxide's high refractive index allows it to reflect harmful UV rays, preventing them from fading paint and retaining its vibrant colors for a long time. This UV resistance is especially important for facades that are exposed to sunlight throughout the day.
