In the "Houston We Have A Problem" thread Kurt said that some nic vendors add citric acid to their nicotine to reduce the peppery taste and (I think) balance the pH. Does anyone know him enough to PM him? I imagine he knows but may be reluctant to tell us because of confidentiality issues with vendors... but maybe not.
Yes, Kurt did say that he felt some vendors are using citric acid to neutralize a strong nic odor & taste. I don't think he knew how many, but I vaguely remember he mentioned one or two by name. In a recent post he said that some have contacted him about testing or getting info on nic. and that most are tight lipped about their liquid but a few are openly working with him.
