What are Nicotine Salts?
At its core, nicotine salts are comprised of the same exact nicotine that's found in its natural state within the tobacco leaf. If this form of nicotine was added to the liquid that we vape, we'd need to vape it at extremely high temperatures for the nicotine solution to be effective, and it still wouldn't be as easily absorbed (bioavailable) as freebase nicotine. Similarly, like freebase, salts need some modification too. The key here is benzoic acid.
