Eli5: How is the alcohol in sanitizers different than in whiskey?

357 views

And if it’s the same then can someone drink sanitizer (a very small portion) and get drunk?

Well, first of all, there’s whole lot of different kinds of alcohols, and only ethanol is somewhat safe for humans (as it’s degraded by ferments in our liver), others can either poison you or cause severe intoxication. Usually, hand sanitizers use either ethanol and/or isopropyl ether, second one is more toxic than first, but somewhat safe in small doses. And first one is usually technical, i.e. it’s actually could be a mixture of mostly ethanol and some fraction of methanol, which is highly toxic. During fermentation, you usually get such mixture and it’s not suitable for food consumption, so it’s distilled, maybe even multiple times, to separate ethanol from methanol. But technical alcohol could be just filtered, so it has relatively high amount of methanol and it’s unsafe for consumption, potentially deadly even.
