Answered by Shaykh Faraz Rabbani
I wanted to ask whether it is haram or makrooh to work with 75% ethanol in a “sterile” laboratory? I am studying in the medical field and some of the work we do in labs requires me to spray ethanol on my disposable lab gloves as well as other items we use in our experimentation. I do try my best to spray away from my face & clothes but I cannot be certain that non of the droplets have touched me. I often have to perform some of my Salat whilst at uni in the same clothes; is there a problem with this?
Non-wine alcohol is not filthy, and unconditionally permissible for external use. [Mufti Taqi Usmani, Dars Tirmizi]
And Allah alone gives success.
