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.”

Regardless of the technique chosen, manufacturers must follow strict protocols to ensure the accuracy and reliability of their results. This includes proper sample preparation, calibration of instruments, and validation of analytical methods. By following these guidelines, manufacturers can confidently determine the level of sulphate in their TiO2 products and ensure that they meet the required standards for their intended applications.

Leading titanium dioxide manufacturers have started to explore alternative synthesis routes that minimize waste and reduce energy consumption. For instance, some have turned to the sol-gel process, which allows for the production of nanoparticles at lower temperatures with better control over the particle size distribution. Others are looking into recycling waste streams from the manufacturing process to recover titanium compounds, thus closing the loop on material use Others are looking into recycling waste streams from the manufacturing process to recover titanium compounds, thus closing the loop on material use Others are looking into recycling waste streams from the manufacturing process to recover titanium compounds, thus closing the loop on material use Others are looking into recycling waste streams from the manufacturing process to recover titanium compounds, thus closing the loop on material usetitanium dioxid manufacturer.
