china 30-50nm tio2 powders quotes

In conclusion, TiO2 plays a pivotal role in pigment manufacturing due to its unparalleled combination of brightness, stability, and safety. Its integration into industrial processes has led to significant advancements in product quality and sustainability while addressing growing concerns over health risks associated with certain materials. As technology evolves and new applications emerge, TiO2 is poised to remain an essential component for pigment manufacturers seeking to deliver high-performance products that exceed customer expectations and regulatory standards alike.

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.
