Titanium dioxide comes in the form of a white powder and is sometimes used in cosmetics to adjust a color to a lighter shade. This is also why it can produce a white cast.
One such manufacturer stands out for its pioneering role in developing eco-friendly production methods. This forward-thinking company has implemented water recycling systems and energy-saving technologies within its plants. By reducing their environmental footprint, they not only comply with strict international regulations but also appeal to a broader clientele concerned with sustainability. Zhejiang Huayi, for instance, is known for its high-purity lithopone products, while Zibo Dongfang Jincheng offers customized solutions to cater to diverse customer needs. Shanghai Kangle, on the other hand, boasts an extensive distribution network, ensuring timely delivery and efficient service.The production process of titanium dioxide powder mainly includes ore selection, acid decomposition, hydrolysis, washing, drying, calcination, and crushing. During this process, strict quality control is required to ensure that the final product meets the relevant standards. Moreover, environmental protection measures must be taken during the production process to minimize the impact on the environment.
A 2022 review on past studies of titanium dioxide and rat lung cancer, for instance, said the original study was under extreme conditions and its effects were not replicated in other animal species. Additionally, the review concluded that the few studies which did directly focus on titanium dioxide's impact on humans did not end up showing any increased cancer risk.
Titanium dioxide (TiO2) is a highly versatile and widely used white pigment that is commonly used in a variety of products such as paints, coatings, plastics, and cosmetics. As a result, there are many manufacturers around the world that produce titanium dioxide in various forms and grades to meet the needs of different industries.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.
