Denatonium also discourages consumption of harmful alcohols like methyl alcohol and ethylene glycol. Denatonium is also used in rubbing alcohol as an inactive ingredient. It is also added to all kinds of harmful liquids including solvents, paints, varnishes, toiletries, and other household products.
Since 1995, when the State of Oregon required that denatonium benzoate be added to antifreeze and windshield wiper fluid, the compound has been increasingly found in these substances throughout the world. The addition is credited with saving children and animals who might otherwise drink sweet antifreeze or wiper fluid and get ethylene glycol or methanol poisoning respectively.
Non-human animals are known to have different sensitivities to the effects of denatonium. It has been used to safeguard rat poisons from human consumption, so presumably rats are not deterred by it, although there is evidence that a small percentage of rodents do avoid such baits. Some cats have been known to be tempted by them — it may not be as effective a deterrent for cats as it is for humans, or perhaps some cats are not deterred due to a genetic factor similar to that affecting human perceptions of the taste of phenylthiocarbamide.
