Interesting. Thanks for that CVS link.

I did some Googling after posting what you replied to above, just to see if I could find references for what you'd suggested was available. Curiously, the only link I found was to that CVS product. There aren't any CVS stores anywhere close to where I live and shop so I'd never have encountered this product w/o seeing your initial post.

Acetone's cheap enough I have to wonder if it's used as an adulterant / denaturing agent for the otherwise 'drinkable' ethanol their rubbing alcohol product is formulated with? In proper dilution it's likely safer than the more common methanol used in commercial 'denatured' alcohol products used for various purposes, which is best kept from contact with your skin.
