Let me clarify my previous post. It concerned the generic term rubbing alcohol as used in the thread. In this context we are discussing the use of isopropyl alcohol. Isopropyl Rubbing Alcohol USP, BP (USP is United States Pharmacopeia and BP is British Pharmacopeia; both are standards set by the government) contains 68-99% of isopropyl alcohol by volume, water, color additives, stabilizers, and perfume oils.
The other type of rubbing alcohol available is Rubbing Alcohol USP, BP. This product uses ethanol as its base (70%). The balance is water and ATF denaturant forumula 23-H (to make it undrinkable) which contains tiny amounts of MIBK (methyl isobutyl ketone), DMK (aka acetone), and ethanol.
Look at the label to see what you are using.
