Firstly, TiO2 is commonly used as a white pigment in plastic products. Its high refractive index and ability to scatter light across the visible spectrum provide excellent opacity and brightness to plastic materials. This makes it an essential component in producing white or light-colored plastics, such as packaging materials, household items, and toys. The addition of TiO2 not only enhances the aesthetic appeal of these products but also improves their overall quality by increasing their durability and resistance to UV radiation.

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.”
