How Is Titanium Dioxide Made?
- The determination of sulfate in various matrices is a critical task for environmental monitoring, industrial process control, and quality assurance in chemical production. When present in high concentrations, sulfates can pose health risks and impact the ecosystem. However, the analytical challenge often lies not just in detecting the presence of sulfates but also in accurately quantifying them, especially when they are to be determined as titanium dioxide (TiO2). This article delves into the methodologies used to determine sulfate as TiO2, highlighting the complexities and nuances involved in such an analysis.






A safety review conducted by the EFSA in 2021 assessed thousands of studies published on titanium dioxide.


Health Canada's Food Directorate recently completed a “state of the science” report on titanium dioxide (TiO2) as a food additive. Food-grade TiO2 is a white powder made up of small particles that has been permitted in Canada and internationally for many years as a food additive to whiten or brighten foods. Food-grade TiO2 has long been considered safe in Canada and in other countries when eaten as part of the diet.



Titanium Dioxide Description
Still many experts say the body of research does not support the current health concerns being expressed about titanium dioxide.

In a study published in 2022 in the journal Particle and Fibre Technology, researchers examined the impact of maternal exposure to titanium dioxide nanoparticles in newborn offspring mice. They found that “a chronic exposure to TiO2 NPs during pregnancy alters the respiratory activity of offspring, characterized by an abnormally elevated rate of breathing.” Breathing was also shown to be “significantly and abnormally accelerated,” and the ability for neural circuitry to effectively adjust breathing rates was impaired. The researchers concluded: “Our findings thus demonstrate that a maternal exposure to TiO2 NPs during pregnancy affects the normal development and operation of the respiratory centers in progeny.”
Most notably, a European Food Safety Authority safety assessment published in May 2021 pointed to genotoxicity concerns, as suggested by previous research. Genotoxicity is the ability of chemicals to damage genetic information such as DNA, which may lead to cancer.
Over the last several years, nanoparticles have come under scrutiny for adverse health effects. Nanoparticles are ultrafine particles between 1 to 100 nanometers in diameter. (To put this in perspective, the average human hair is around 80,000 nanometers thick.) Because of their size, which can be engineered and manipulated at the atomic or molecular level, nanoparticles exhibit unique physical, chemical, and biological properties. Titanium dioxide is one of the most commonly produced nanoparticles in the world.
