> Why can you go to the store and buy rubbing alcohol to drink? It’s primary ingredient is just ethanol.
AFAIK most/all rubbing alcohol (at least that which is sold in the US) is isopropanol, not ethanol. You can buy ethanol in not-for-consumption form, as denatured alcohol.
And it’s chemistry that forces the additional benzene in denatured alcohol. Water- ethanol forms an Azeotrope at 95% ethanol. Benzene is added to break the azeotrope and get to 99.99% ethanol. Chemistry not a conspiracy
No one is selling 70% ethanol as an antiseptic, it's isopropyl alcohol. Those additives in ethanol not intended for consumption are 8 parts acetone and 1.5 parts methyl isobutyl ketone to 100 parts ethanol. There are some rare ethanol based rubbing alcohols sold but the vast majority is isopropyl because it's not just denatured with bitterants, they add toxic substances as well.
