Nicotine malate salt is a chemical compound formed by combining nicotine with malic acid, resulting in a salt form. It is commonly used in the manufacturing of nicotine-based products, including pharmaceutical formulations and e-liquids for vaping. Nicotine malate salt offers certain advantages, such as improved stability and solubility compared to freebase nicotine. This makes it suitable for various applications where controlled release and enhanced bioavailability are desired. When used in e-liquids, nicotine malate salt can provide a smoother vaping experience with reduced throat irritation. However, it's important to handle nicotine malate salt with caution, as nicotine is a highly toxic substance. Proper safety protocols should be followed during handling, storage, and use to prevent accidents or exposure.
