Both 28B301 and 30B311 are white pigments with high brightness and excellent covering power. They are commonly used in coatings, plastics, rubber, and paper industries. The main difference between these two grades lies in their particle size distribution. 28B301 has a smaller particle size, resulting in higher opacity and better dispersion. On the other hand, 30B311 has a larger particle size, which makes it more suitable for applications that require good rheological properties.

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JECFA, titanium dioxide has become a public point of contention, with its ban being introduced (and then subsequently withdrawn) in California legislation in 2023, a legal battle playing out in the EU over the additive’s ban and classification as a carcinogen in 2022, and the European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.
