About:
Denatonium benzoate is the most bitter chemical compound known to science. It is colorless and odorless and is sold under the trade name of Bitrex®. It is used to denature ethanol so that it is not treated as an alcoholic beverage with respect to taxation and sales restrictions. It is added to products containing ethylene glycol and methanol such as antifreeze and windshield washer fluid to prevent the accidental poisoning of children and animals.
Fun Facts:
- The claim that denatonium benzoate is the most bitter-tasting chemical known is based not on scientific tests but on human taste tests alone. No automated test exists for determining the bitterness of a substance. [2]
- Oregon was the first state in the United States to require the addition of Bitrex® to antifreeze and car windshield washer fluid. The requirement was instituted to prevent people from drinking such products accidentally or, in the case of alcoholics, intentionally. [2]
