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.
Titanium is a common metal element frequently found throughout nature. In our environment, titanium is naturally exposed to oxygen, forming titanium oxides that we find in many minerals, dusts, sands, and soils.
