What is salt nicotine?
From the chemical perspective, nicotine salts are compounds of pure nicotine with some organic acid for example benzoic acid, or malic acid. In other words, nicotine salts are just another chemical form of nicotine to be blended with PG/VG. The difference, however, between nicotine salts and pure nicotine is not only the chemical structure but also the vaping experience of users.
Because of the lower pH level of nicotine salts (around 5) than traditional pure nicotine, nicotine salts are more biocompatible with the human organism. In other words, nicotine salts do not provide vapers with the harshness on the throat, so-called “throat hit”.
How are nic salt e-liquids different from the ordinary pure nicotine e-liquids?
Because of the less harshness on the throat, users of nicotine salts e-liquids can vape them with the higher nicotine strengths without uncomfortable, or unpleasant sensations. This leads to a greater nicotine fix which can be compared to the one after smoking an ordinary cigarette. For this reason, nicotine salts e-liquids are an ideal solution for people who would like to switch from or completely quit smoking.
Most of the traditional e-liquids with pure nicotine (not salts) are ideal for sub-ohm vaping which produces large vapor clouds. Nicotine salts, on the other hand, require different equipment.
