china formation of titanium dioxide

One of the key reasons why TiO2 is favored by paper suppliers is its excellent light-scattering properties. When added to paper, TiO2 particles scatter light, making the paper appear brighter and more opaque. This is crucial for producing high-quality papers that are aesthetically pleasing and easy to read. TiO2 also helps to enhance the whiteness of paper, giving it a clean and crisp appearance that is highly desirable in the paper industry.

For a review published in 2023 in the journal Environmental Pollution, researchers examined E171 as a possible factor promoting obesity-related metabolic disorders. Because gut microbiota play an important role in immune function maintenance and development, and because titanium dioxide as a food additive has been shown to alter gut microbiota, researchers wanted to review “the dysregulations along the gut microbiota-immune system axis after oral TiO2 exposure compared to those reported in obese or diabetic patients, and to highlight potential mechanisms by which foodborne TiO2 nanoparticles may increase the susceptibility to develop obesity-related metabolic disorders.” The study authors discovered recurrent changes in the gut microbiota composition when exposed to titanium dioxide nanoparticles, with an imbalance of intestinal symbiotic microbiota. These changes and imbalances were also reported and played a role in the development of obesity, the authors wrote. This highlights “foodborne TiO2 nanoparticles as an endocrine disruptor-like chemical promoting obesity-related disorders,” the authors concluded.
