Eli5: Why does the alcohol in alcoholic beverages smell different from the alcohol in beauty/hygiene products?
gpt
There are different types of alcohol.  Primarily:

- Isopropyl Alcohol (aka rubbing alcohol...what a nurse rubs on your arm before drawing blood)
- Methyl Alcohol (aka methanol...usually used as a solvent)
- Ethyl Alcohol (aka grain alcohol...what people drink)

You *definitely* do not want to drink the first two.  What they use in hygiene products is usually isopropyl alcohol.
