Nicotine dilutions in VG/PG base refer to solutions containing nicotine dissolved in a mixture of vegetable glycerin (VG) and propylene glycol (PG). These solutions are commonly used in the production of e-liquids for vaping. The VG/PG base serves as a carrier for the nicotine, allowing it to be vaporized and inhaled when heated in a vaping device. Nicotine dilutions in VG/PG base come in various concentrations, allowing users to choose the desired nicotine strength for their e-liquids. When handling nicotine dilutions, it's crucial to follow safety guidelines and use protective measures due to the toxicity of nicotine.
