A bitterant (or bittering agent) is a chemical that is added to a product to make it smell or taste bitter. Bitterants are commonly used as aversive agents to discourage the inhalation or ingestion of toxic substances.
Examples of use
- The addition of a bitterant to ethanol denatures the product.
- Bitterants are used in antifreeze to prevent pet and child poisonings. It is required by law in some places (France, Oregon, etc.)
- Gas dusters often use a bitterant to discourage inhalant abuse, although this can cause problems for legitimate users. The bitterant not only leaves an intolerably bitter flavor in the air, but also leaves a bitter residue on objects, like screens and keyboards, that may transfer to hands and cause problems (such as when eating).
Examples of bitterants
- Denatonium is used in a variety of applications as an aversive agent.
- Sucrose octaacetate
- Denaturation (food), the deliberate addition of an unpleasantly flavored or poisonous substances to food in order to prevent the consumption of the food for various reasons.
- Adulterant, a substance added to food for deceptive or malicious reasons, for example to cheaply replace legitimate ingredients.
