Denatonium benzoate powder is a bitter-tasting compound used as an aversive agent in industrial and consumer products to prevent accidental ingestion. It is widely used as an alcohol denaturant, as a bittering additive in hazardous products such as antifreeze, and as an inert ingredient in non-food pesticide formulations. It is a white to off-white crystalline powder with a molecular formula of C21H29N2O · C7H5O2 and a molecular weight of 446.58 g/mol. It is stable at ambient temperatures and carries the GHS signal word Danger because it causes serious eye damage (H318); it is also harmful if swallowed (H302) or inhaled (H332) and harmful to aquatic life with long lasting effects (H412).
