Because of its many varied properties, our skin, cities, cars, homes, food and environment are made brighter, safer, more resilient and cleaner by TiO2. With a legacy of 100 years of safe commercial use, TiO2 is only going to become more vital as our environment faces greater challenges from a growing population.
But this is just the tip of the ice berg so many articles & studies are coming out challenging the safety of Titanium Dioxide in our food supply & personal care products.
The gastrointestinal tract is a complex barrier/exchange system, and is the most important route by which macromolecules can enter the body. The main absorption takes place through villi and microvilli of the epithelium of the small and large intestines, which have an overall surface of about 200 m2. Already in 1922, it was recognized by Kumagai, that particles can translocate from the lumen of the intestinal tract via aggregation of intestinal lymphatic tissue (Peyer’s patch, containing M-cells (phagocytic enterocytes)). Uptake can also occur via the normal intestinal enterocytes. Solid particles, once in the sub-mucosal tissue, are able to enter both the lymphatic and blood circulation.
Ultimately, most experts advise moderation, as titanium dioxide is typically found in processed foods that come with their own health risks.
In food, titanium dioxide is often used as an artificial color additive. Tasha Stoiber, senior scientist at the consumer health nonprofit Environmental Working Group, says titanium dioxide can generally be thought of as a paint primer – it often goes on a hard-shelled candy like Skittles before the color is added to give it a uniform shine.
To ensure the optimal precipitation percentage, it is important to carefully control these factors during the precipitation process. For example, a higher concentration of titanium sulfate will typically result in a higher precipitation percentage, but may also lead to the formation of impurities. On the other hand, a lower pH of the reaction mixture can promote the precipitation of titanium hydroxide, but may also result in a lower precipitation percentage.
