I work in the medical field in a hospital. All of us are expected to use alcohol-based hand sanitizers containing high percentages of alcohol to kill dangerous bacteria exposed on our skin. This alcohol is made from ethyl alcohol, not isopropyl (rubbing) alcohol.

My question is whether or not exposure to this form of industrialized alcohol on the skin nullifies wudhoo (ritual ablution)?

All such alcohols are tahir and can be used for sanitizing and cleaning things and namaz is valid with such industrial alcohols except for muqalideen of Ayatullah Hafiz Basheer Najfi
