Naw. It has an assay breakdown of impurities on the label. There is no benzene. And how would adding an impurity (benzene) make it more pure?
That's what I thought. I think most of the acetic acid neutralized though. There is barely nay vinegar smell left. The freebase AMT took a lot of it up.
Well, ethanol forms an azeotrope with water and thus cant be distilled higher than 96% ethanol. To make 100% pure ethanol they often add bezene with forms an azeotrope with ethanol and water. This azeotrope has a lower BP than the water/ethanol azeotrope and can be distilled off. But this leaves a little residue of benzene behind which is pretty toxic. So technically its not 100%, but for that matter there is no such thing as 100% ethanol.
There are other ways of doing this however, so I guess your ethanol is a bid different from the usual 99,99% from the lab

Would there be any downside (as in the longevity of AMT) to accidentally adding a little more vinegar than necessary? Personally, I like the taste of vinegar so long as it is not harsh enough to hurt my throat.
Also, is it more effective to take an alkaloid salt sublingually than its freebase?
I think it would be a good idea adding extra vinegar. It consrvates your solution much better if theres a bit of surplus acetic acid.
I dont think it would matter whether the alkaloid youre referring to is salt or freebase. You have plenty of HCl in your stomach, so its gonna be converted to the alkaloid salt under all circumstances.
