But in 2021, EFSA reevaluated titanium dioxide to consider the impacts of its nanoparticle. After considering more studies, EFSA concluded that nanoparticle-size titanium dioxide can accumulate in the body, break DNA strands and cause chromosomal damage.
Key benefits for stakeholders
As a key ingredient in solar panels, titanium dioxide helps to harness the power of the sun and convert it into clean energy As a key ingredient in solar panels, titanium dioxide helps to harness the power of the sun and convert it into clean energychina 98%min titanium dioxide anatase. By investing in the development of solar technology, China is not only reducing its reliance on fossil fuels but also helping to mitigate the effects of climate change.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.”
