What is nicotine salt, what is the difference between nicotine salt e-liquid and ordinary e-liquid? Nicotine salt has become the main trend this year. More and more e-liquid manufacturers are trying to use nicotine salt. How much do you know about salt-based nicotine and its chemical composition? Where does the salt come from? Nicotine is naturally present in tobacco leaves and in the form of salt, but this particular salt is not suitable for evaporation in vape.

General structure of nicotine salt

In the late 1950s and early 1960s, tobacco companies began to add ammonia or diammonium phosphate to tobacco to improve the taste of cigarettes.

This creates a "free base" form of nicotine that can inhale the blood faster when smoking, which makes smokers more satisfied, and has dominated the tobacco market for decades. In order to separate nicotine from tobacco leaves, it is first converted to its free base form and then solvent extraction is used. This free radical nicotine is most commonly used for atomization in Vape, but the absorption rate of nicotine is lower compared to cigarettes. This may be due to the larger vapor particle size compared to tobacco particulates, which prevents deep penetration of the lungs (usually the fastest nicotine acquisition rate is produced deep in the lungs).

By investigating the monitoring of heart rate, user-reported satisfaction and measuring the plasma nicotine level of test participants in experimental studies, it was found that the amount of nicotine absorbed by certain nicotine preparations containing organic acids after evaporation is equivalent to that of cigarettes. In addition, these formulas improve the stability of the nicotine (longer shelf life) and reduce the damage to the throat of the free-radical nicotine commonly used by vaper (feel more gentle). This is why some people believe that nicotine salts are more useful for quitters, because nicotine is more effective for smokers and they feel more satisfied when they switch to Vaping. One of the formulas is nicotine benzoate, which is formed by adding benzoic acid to nicotine. This is also the most commonly used nicotine salt formulation in popular small cigarette devices in the United States.
