Packaging containing this additive has been shown to decrease ethylene production in fruit, thus delaying the ripening process and prolonging shelf life (4Trusted Source).
Nano-sized TiO2 generally shows low or no acute toxicity in both invertebrates and vertebrates. However, exposure of Daphnia magna to 20 ppm TiO2 for 8 consecutive days was found to cause 40 % mortality. Zhu et al. showed minimal toxicity to D. magna after 48 h exposure, while upon chronic exposure for 21 days, D. magna suffered severe growth retardation and mortality. A significant amount of nano-sized TiO2 was found also accumulated in the body of the animals. Similar findings with coated nano-sized TiO2 (T-Lite™ SF, T-Lite™ SF-S and T-Lite™ MAX; BASF SE) were reported by Wiench et al. Biochemical measurements showed that exposure to TiO2 NPs induces significant concentration-dependent antioxidant enzyme activities in D. magna. Lee et al. showed that 7 and 20 nm-sized TiO2 induced no genotoxic effect in D. magna and in the larva of the aquatic midge Chironomus riparius.
③ Paper making industry: Paper making and paper products industry is the third largest application industry of titanium dioxide. Paper using titanium dioxide has good whiteness, high strength, luster, thin and smooth, and is not easy to penetrate when printing. Under the same conditions, the opacity is 10 times higher than that of paper using calcium carbonate and talc powder, and the weight can also be reduced by 15% to 30%. The amount of titanium dioxide in decorative paper accounts for 20%~40% of its raw materials, and the amount of titanium dioxide in other papers is about 1%~5%. Due to the continuous adjustment of the industrial structure of the paper products industry from 2016 to 2018, according to the data of China Paper Association, the output of China's paper products in 2019 was 72.19 million tons, a significant year-on-year increase of 29.4%, and the use of titanium dioxide increased significantly.
