Nicotine dilutions in VG/PG base refer to nicotine solutions that are diluted in a mixture of vegetable glycerin (VG) and propylene glycol (PG). These solutions are commonly used in the production of e-liquids for vaping. Nicotine is typically dissolved in a high concentration and then mixed with VG and PG to achieve the desired nicotine strength for the final e-liquid product. The ratio of VG to PG can vary depending on the preferences of the manufacturer or the desired characteristics of the e-liquid. VG/PG-based nicotine dilutions allow for precise control over nicotine levels in e-liquids while also providing a smooth vaping experience. As with any nicotine-containing product, proper safety precautions should be followed during handling and usage.
