Salt nicotine, also known as nicotine salt or nic salt, is a type of nicotine that has been modified to provide a smoother and more satisfying vaping experience. The main difference between salt nicotine and base nicotine lies in their chemical composition and the way they affect the throat and lungs when inhaled.
Base nicotine, also referred to as freebase nicotine, is the purest form of nicotine that is commonly used in e-liquids. It is extracted from the tobacco plant and then undergoes a chemical process to remove impurities and increase its potency. This results in a highly concentrated nicotine solution that can be added to e-liquids to provide a strong nicotine hit.
However, base nicotine can feel quite harsh on the throat, especially at higher concentrations. This is because it has a more alkaline pH, making it more basic on the pH scale. When vaping e-liquids with high-strength base nicotine, users may experience a strong throat hit, which can be uncomfortable for some individuals.
On the other hand, salt nicotine has been modified to have a lower pH, making it more acidic and closer to the pH of tobacco leaves. This modification is achieved by combining nicotine with an organic acid, such as benzoic acid. The addition of the acid reduces the alkalinity of the nicotine, resulting in a smoother and less harsh vaping experience.
The lower pH of salt nicotine allows it to be vaped at higher concentrations without causing excessive throat irritation. This is why salt nicotine e-liquids are often available in higher strengths, such as 25mg or 50mg, compared to the typical maximum strength of 18mg for e-liquids containing base nicotine.
The smoother sensation of salt nicotine also allows for a quicker nicotine absorption in the body, mimicking the rapid nicotine delivery of traditional cigarettes. This can be particularly beneficial for individuals who are trying to quit smoking and are looking for a more satisfying alternative.
It is important to note that the choice between salt nicotine and base nicotine ultimately comes down to personal preference. Some vapers may prefer the stronger throat hit provided by base nicotine, while others may find the smoother experience of salt nicotine more enjoyable.
The main difference between salt nicotine and base nicotine lies in their pH levels and how they feel when inhaled. Base nicotine is more alkaline and can feel harsher on the throat, especially at higher concentrations. Salt nicotine, on the other hand, has been modified to have a lower pH, resulting in a smoother and more satisfying vaping experience.
