Some people have concerns about the safety of titanium dioxide because of reports linking it to cancer.
Because of their small size, nanoparticles may have unique physical and chemical properties. These properties may cause them to interact with living systems differently than larger materials with the same chemical composition (also known as bulk materials).
China’s government is working on its plan to eliminate outmoded capacities of TiO2 and strengthen environmental protection measurements. Small and middle-sized enterprises, with a production capacity under 50,000t/a, are the ones to suffer. They mostly get merged or need to withdraw from the market. Without their production capacity of about 500,000 tonnes yearly, the domestic output might shrink about 20%. This will enhance the power of listed companies in China immensely, which is one of the main reasons for the effort to go public.
Thirdly, titanium dioxide is a semiconductor material with a wide bandgap energy of 3
