DENATONIUM BENZOATE

Safety grade: A

Denatonium benzoate is a synthetic chemical that tastes extremely bitter and is added to products to discourage accidental swallowing or ingestion. It's commonly used in products like nail polish and other cosmetics that shouldn't be eaten.

This ingredient serves as a denaturant and masking agent, making the product taste unpleasantly bitter to prevent accidental ingestion while also helping to mask other undesirable tastes in the formula.
