• Recent EU Clinical Trials: Evaluation of the protection activity of microfine Ti02, pigmentary Ti02 and bisoctrizole and their combinations in voluntary patients with idiopathic solar urticaria (SU): phase II photoprovocation test.
• Inhalation Risk: A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered.
• Effects of Long Term Exposure: Lungs may be affected by repeated or prolongated exposure. This may result in chronic inflammation. This substance is possibly carcinogenic to humans if inhaled.
• Regulation and Approval: The FDA approved the use of titanium dioxide in food in 1966. In a brief statement to industry issued in June 2023, the FDA claims it has evaluated EFSA's opinion and concluded that titanium dioxide is safe.; The European Commission banned titanium dioxide as a food additive in 2022 due to concerns about genotoxicity.
• Industrial Usage: Titanium dioxide is a semiconducting material and chemically inert, widely used in different applications.; Titanium dioxide is extensively used as a white pigment in various applications. It offers advantages such as high stability, non-toxicity, and low cost. The two useful crystal forms for pigment applications are anatase and rutile.; Titanium dioxide is a food additive used to enhance the color of food, prevent spoilage, and extend shelf life. It's also used as a thickener and to keep powdered foods from clumping.; Used in solar panels to reduce air pollutants. Titanium dioxide particles scatter visible light effectively due to their high refractive indices.
• Environmental Applications: Titanium dioxide has emerged as an excellent photocatalytic material for environmental applications.; Factors such as particle morphology, crystal structure, and electronic and optical properties influence its photocatalytic activity.; Photocatalytic oxidation technology using titanium dioxide can efficiently degrade organic pollutants into harmless inorganic substances.
• History and Development: Titanium dioxide is found in many minerals, sands, soils, and dusts on Earth. For example, titanium oxides are found in black magnetic sand in Cornwall, discovered by William Gregor in 1791. In 1795, M H Klaproth isolated the oxide from mineral rutile in Hungary. However, the first commercial production of titanium dioxide pigment did not take place until the 1920s.; Research on titanium dioxide's photocatalytic properties dates back to the 1970s. It has been found effective in degrading pollutants such as polychlorinated biphenyls and cyanide. Titanium dioxide has advantages over traditional catalytic methods in terms of photocatalytic reaction conditions, pollution-free process, and recyclability.
