A nicotine solution typically refers to a liquid formulation containing nicotine dissolved in a solvent, often propylene glycol (PG) or vegetable glycerin (VG). This solution is commonly used in the production of e-liquids for electronic cigarettes and vaping devices. Nicotine solutions come in various concentrations to accommodate different preferences and nicotine strengths desired by users. They are carefully formulated to ensure consistency, purity, and quality, meeting regulatory standards for safety and efficacy. Nicotine solutions are versatile and can be further customized with flavorings and additives to create a wide range of vape juices catering to diverse consumer preferences.
