I had previously used vodka in a topical and had horrible side effects from it. Making SolBan, I assumed that the vodka was a small enough amount that I could use it topically with no symptoms. NOT so.

Doing a bit of research I found that there are impurities in vodka. Ok, so I'll get the Lab Alley ethanol off Amazon--nope. Reviews indicate a high amount impurities such as ethyl acetate, and nasty symptoms from drinking (and yes, it's undenatured).

I have found some other potentially usable brands of ethanol.

But I'm also interested in the idea of an alternative solvent. AI is suggesting a mixture of propylene glycol, glycerine, and water. Interesting. I guess it would be more of a lotion, and I would have to figure out what concentrations of the active ingredients to use.
