However, China's ascendancy in the titanium dioxide market has also raised environmental concerns. The production process involves significant energy consumption and generates carbon dioxide emissions. With the CAS number 13463-67-7, titanium dioxide production contributes to global greenhouse gas emissions, posing a challenge for sustainable development With the CAS number 13463-67-7, titanium dioxide production contributes to global greenhouse gas emissions, posing a challenge for sustainable development With the CAS number 13463-67-7, titanium dioxide production contributes to global greenhouse gas emissions, posing a challenge for sustainable development With the CAS number 13463-67-7, titanium dioxide production contributes to global greenhouse gas emissions, posing a challenge for sustainable developmentchina dioxide titanium cas 13463-67-7.

Moreover, NIOSH has also delved into the emerging field of nanotechnology, where TiO2 nanoparticles find applications in sunscreens, self-cleaning surfaces, and air purification systems. These nanoparticles can have different toxicological properties than their bulk counterparts, necessitating a more nuanced approach to risk assessment These nanoparticles can have different toxicological properties than their bulk counterparts, necessitating a more nuanced approach to risk assessment These nanoparticles can have different toxicological properties than their bulk counterparts, necessitating a more nuanced approach to risk assessment These nanoparticles can have different toxicological properties than their bulk counterparts, necessitating a more nuanced approach to risk assessmentniosh titanium dioxide. NIOSH has published guidelines and hazard evaluations to address potential exposure risks and promote safe handling practices.

The production process of titanium dioxide involves several stages, starting with the extraction of raw materials from mineral ores such as ilmenite, rutile, and anatase. These ores are then processed through various methods, including the sulfate and chloride processes, to produce high-purity titanium dioxide powder. The sulfate process involves treating the ore with sulfuric acid to extract titanium dioxide, while the chloride process uses chlorine gas to produce a purer form of the pigment.

JECFA previously assessed titanium dioxide at its 13th meeting, at which time the expert committee assigned a “not specified” ADI for the additive due to an absence of significant absorption and a lack of toxicological effects in the available experimental animal and human studies. Since its original evaluation by JECFA, titanium dioxide has become a public point of contention, with its ban being introduced (and then subsequently withdrawn) in California legislation in 2023, a legal battle playing out in the EU over the additive’s ban and classification as a carcinogen in 2022, and the European Food Safety Authority (EFSA) calling titanium dioxide unsafe. However, supporters of titanium dioxide say that claims about its dangers are founded in unreliable studies, and some recent research has supported its safety as a food additive.
