Denatonio
Denatonio is a term that does not correspond to a widely recognized chemical, concept, or entity in established reference works. In many contexts, it appears to be a misspelling or variant of denatonium, a chemical used as a bittering agent to deter ingestion. Denatonium, commonly encountered in the form of denatonium benzoate, is notable for its extreme bitterness and is added to a range of products—including household cleaners, cosmetics, and some medications—to discourage accidental and intentional ingestion.
Because denatonio is not a standard name in regulatory or scientific databases, its exact meaning can vary
