  • The FDA first approved the use of titanium dioxide in food in 1966, following its 1960 removal (along with the removal of other color additives) from the agency's original Generally Recognized as Safe list. In 1977, titanium dioxide joined the list of color additives that are exempt from certification, which means titanium dioxide doesn't have to be listed on the packaging of every product it's used in, Faber noted.

  • The rutile market is dominated by a few key manufacturers who supply the majority of the world's rutile. These manufacturers are primarily located in countries with abundant mineral resources, such as Australia, South Africa, and China. Some of the leading rutile manufacturers include Iluka Resources, Tronox Limited, Rio Tinto, and Guangdong Huiyun Titanium Industry Co., Ltd.

  • Titanium dioxide is often used as a UV absorber and pigment in cosmetic products, such as foundations, lipsticks, creams, sunscreens and other skin care products. It helps protect the skin from the harmful effects of UV rays by blocking them, while providing a brightening effect.

  • Economic conditions, such as inflation, interest rates, and exchange rates, can also impact titanium prices. A strong economy typically leads to higher demand for titanium, driving up prices. On the other hand, a weak economy can result in lower demand and lower prices. In addition, fluctuations in the value of the US dollar can affect the cost of imported titanium products.

  • Of the products that include the additive in their labels, Thea Bourianne, senior manager at data consultant Label Insights, told Food Navigator USA in May 2021 that more than 11,000 products in the company's database of U.S. food and beverage products listed titanium dioxide as an ingredient. Non-chocolate candy led those numbers at 32%. Cupcakes and snack cakes made up 14%, followed by cookies at 8%, coated pretzels and trail mix at 7%, baking decorations at 6%, gum and mints at 4% and ice cream at 2%.

  • NIOSH's primary concern with titanium dioxide lies in its use as a pigment in paints, plastics, and other industrial products, where workers may be exposed to airborne particles. TiO2 is generally considered safe when used in its solid form; however, inhalation of fine dust particles can pose respiratory risks. NIOSH conducts rigorous studies to establish recommended exposure limits (RELs) to ensure worker safety.

  • No acute effects of nano-sized TiO2 were observed in Danio rerio (zebrafish) embryos. Exposure of rainbow trout to TiO2 NPs triggered lipid peroxidation, influence on the respiratory tract, disturbance in the metabolism of Cu and Zn, induction of intestinal erosion  and accumulation in kidney tissue. Linhua et al. exposed juvenile carp to 100 and 200 mg/ml of particles and TiO2 observed no mortality. However, the fish suffered from oxidative stress and pathological changes in gill and liver. In the infaunal species Arenicola marina, exposure to TiO2 NPs in sediment caused sub-lethal effects including decrease in casting rate and increase in cellular and DNA damage. Aggregated particles were visible in the lumen of the gut, but no uptake through the gut or the skin was observed.

  • EFSA’s scientific advice will be used by risk managers (the European Commission, Member States) to inform any decisions they take on possible regulatory actions.

  • It is a white crystalline powder, which is a mixture of zinc sulfide and barium sulfate. The more zinc sulfide it contains, the stronger the hiding power and the higher the quality. The density of lithopone is 4.136~4.34/cm3 and it is insoluble in water. It easily decomposes when exposed to acid to produce hydrogen sulfide gas, but does not work when exposed to hydrogen sulfide and alkaline solutions.
