Summary

Titanium dioxide (E171) is a white pigment used as a food colorant in candies, chewing gum, coffee creamer, and sauces. It was banned by the European Union in August 2022 after EFSA concluded it could not rule out genotoxicity concerns. It remains FDA-approved in the United States.

Silicon dioxide (SiO2) is a naturally occurring compound used as an anti-caking agent in food products to improve flow and prevent clumping. It is recognized as safe by the FDA and is widely used in powdered foods, seasonings, and supplements at very low concentrations.
