TiO2 comes in many different forms. However, only a few of these forms are considered food-grade (acceptable to be added to food). Many studies that raised concern about the safety of TiO2, including the concern for genotoxicity, used forms of TiO2 that are not considered acceptable for use in food and have different properties than food-grade TiO2. Other studies did use food-grade TiO2, but took steps to break the material down into smaller particles than what would normally be found in food.
On the other hand, Lithopone B301 is a lower-grade pigment with a lower zinc sulfide content compared to B311. While B301 may not offer the same level of performance as B311, it is still a cost-effective option for applications where high opacity is not a priority
But this is just the tip of the ice berg so many articles & studies are coming out challenging the safety of Titanium Dioxide in our food supply & personal care products.

Now if your an Aussie, I am sure you have seen the Bluescope Steel add about how it stands up to the test of time & the elements – but a little bit of titanium dioxide & it’s all over!!!
