Gravimetric Determination of Titanium Dioxide in Industrial Applications

The California plaintiff is apparently not the only one concerned about titanium dioxide. The European Union recently banned its use citing concerns about serious health consequences.

The most significant uncertainty identified by the EU experts was the concern that TiO₂ particles may have genotoxic effects. Genotoxicity refers to the ability of a chemical to directly damage genetic material within a cell (DNA), which may lead to cancer in certain situations. Although the experts did not conclude that TiO₂ particles in E171 are genotoxic, they could not rule out the concern that they might be.

Moreover, the region of sourcing can also impact pricing. Suppliers in different geographical locations may offer varied prices due to differences in transportation costs, availability of raw materials, and local market conditions. Buyers must consider these regional variances when negotiating prices and establishing long-term relationships with suppliers. In many cases, sourcing from manufacturers that can produce high-quality lithopone pigments at competitive rates can lead to significant cost savings.
