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.

China's dominance in the production of titanium dioxide is largely due to its vast mineral reserves and advanced processing technology. With a focus on achieving a minimum purity of 98%, Chinese manufacturers are able to produce high-quality titanium dioxide that meets the stringent requirements of various industries. This commitment to excellence has helped China establish itself as a global leader in the production of titanium dioxide.
