If it says isopropyl alcohol or pure isopropyl alcohol on the bottle, 
then you're okay.  Most of the time, there is a percentage like 70% or 
90%, etc.  That's the percentage of alcohol to water.  I can usually find 
upwards of 97% pure in a just regular drugstore.  However, if it says 
RUBBING alcohol, that has oil in it as a lubricant for massages; hence, 
the, name rubbing.  There's not much, but it's there.
