One of the key factors affecting TiO2 manufacturing is the choice of raw materials. Rutile and anatase are the two most common forms of TiO2, each with its own unique properties and applications. Rutile is known for its higher refractive index and hardness, making it suitable for use in coatings, plastics, and other high-performance applications. Anatase, on the other hand, has better photocatalytic activity and is often used in environmental protection and solar energy applications.

In 2017, French researchers from the Institut National de la Recherche Agronomique (INRAE) were among the first to examine the effects of E171 nanoparticles on the body. They fed rats a dose of 10mg of E171 per kilogram of body weight per day, which was similar to human exposure in food. The research, which was published in Scientific Reports, showed that E171 was able to traverse the intestinal barrier, pass into the bloodstream, and reach other areas of the body in rats. Researchers also found a link between immune system disorders and the absorption of titanium dioxide nanoparticles.
