Salt-nicotine e-liquid is a vape e-liquid (electronic cigarette) containing salt-nicotine. Salt-nicotine is a form of nicotine extracted with added benzoic acid to reduce the alkalinity (pH) of nicotine, making salt-nicotine e-liquid vaporize better at low temperatures, making users feel less sore throat when using high doses of salt nicotine. The commonly used salt nicotine concentration is from 20mg to 50mg.
