In addition to its functional benefits, titanium dioxide also plays a crucial role in UV protection. It acts as a shield against harmful ultraviolet radiation, preventing premature degradation and maintaining the integrity of the rubber over time It acts as a shield against harmful ultraviolet radiation, preventing premature degradation and maintaining the integrity of the rubber over time It acts as a shield against harmful ultraviolet radiation, preventing premature degradation and maintaining the integrity of the rubber over time It acts as a shield against harmful ultraviolet radiation, preventing premature degradation and maintaining the integrity of the rubber over timetitanium dioxide for rubber supplier. This is particularly important in outdoor applications where rubber products are exposed to sunlight and weathering.

A few non-dietary studies have reported adverse effects in the gastrointestinal tract of laboratory animals given food-grade TiO2. However, these same effects were not seen when the same or higher doses of food-grade TiO2 were administered in the animals' diet. Dietary studies best reflect how humans are exposed to TiO2 from food. Thus, the Food Directorate placed the most emphasis on the results of these studies in the state of the science report.

In a study published in the journal Environmental Toxicology and Pharmacology in 2020, researchers examined the effects of food additives titanium dioxide and silica on the intestinal tract by grouping and feeding mice three different food-grade particles — micro-TiO2, nano-TiO2, and nano-SiO2.  With all three groups, researchers observed changes in the gut microbiota, particularly mucus-associated bacteria. Furthermore, all three groups experienced inflammatory damage to the intestine, but the nano-TiO2 displayed the most pronounced changes. The researchers wrote: “Our results suggest that the toxic effects on the intestine were due to reduced intestinal mucus barrier function and an increase in metabolite lipopolysaccharides which activated the expression of inflammatory factors downstream. In mice exposed to nano-TiO2, the intestinal PKC/TLR4/NF-κB signaling pathway was activated. These findings will raise awareness of toxicities associated with the use of food-grade TiO2 and SiO2.”
