Dilutions of as little as 10\u00a0ppm\u00a0are unbearably bitter to most humans. Denatonium salts are usually colorless and odorless solids but are often traded as solutions. They are used as\u00a0aversive agents\u00a0(bitterants) to prevent inappropriate\u00a0ingestion. Denatonium is used in\u00a0denatured alcohol,\u00a0antifreeze,\u00a0nail biting\u00a0preventions,\u00a0respirator\u00a0mask\u00a0fit-testing,\u00a0animal repellents,\u00a0liquid soaps, and\u00a0shampoos.
