99% Isopropyl is cheaper and just as good for the purpose - and it does not go into your liver within 20 seconds after skin contact. (So I have been told by two separate PhD research chemists, while thanking me for my recommendation ...)
Test: Wearing a painter-grade NIOSH respirator (ie: 3M 6200 + 6000 filters) wet a finger with acetone while watching the second timer tick down. When you taste it you have it.
