Hello. I am performing some biochemical process where the end product is going to be intended for human consumption. I am curious where I can buy large quantities of ethanol that is safe for drinking. I don't want to use the liquor store corn alcohol because it has some impurities reintroduced back in to it to make it taste better. This is not what I need. No, I am not planning to drink it. No, I am not making drugs. I live in United States, in the state of Maryland. What kind of permits do I need to buy laboratory-grade, non denatured ethanol that doesn't smell like cheap corn booze and can be used to make extractions? Thank you.
