You don't want to touch gasoline. Alcohol is fine, if its just Ethanol. You don't want to touch Methanol. The trouble is getting a pure alcohol without any methanol in it. Methanol turns to formaldehyde when it comes into contact with alcohol dehydrogenase, a common enzyme. So beware any hand sanitizer that contains methanol, it is not safe to touch. We get 100% Ethanol in our lab, very expensive. I use the pure stuff for tissue dehydration, wax embedding, and denatured versions for sanitation/sterilizing when diluted to 70% with water. Being so familiar with these and other dangerous liquids is why I stress their properties, to people who probably rarely see them in their full strength. |
