What is PG/VG? How to choose?

All the flavors, vapor and nicotine levels are decided by the e-liquids, batteries just play a role of heating and atomizing e-liquids to vapors, so this time we only analyze e-liquids separately. What’s E-liquid? E-liquid was defined as a substance carrier that atomizes a particular liquid into vapor by a atomizer device. It is mainly composed of four components: PG (propylene glycol), VG (vegetable glycerin), flavor and nicotine.

PG is an abbreviation for propylene glycol. It is a colorless, odorless, sparse, and slightly viscous by-product of petroleum. It absorbs flavors in E-liquid, that’s why some high PG E-liquids have stronger flavor and aroma. During the vaping, PG produced a distinct throat hit which is similar to the traditional cigarette. The FDA describes PG as a "general safety object" as a food additive, indicating that it is safe for the human body. However it’s side effects are also obvious: thirst, dry mouth, sore throat.

VG was called "VegetableGlycerin". VG is a non-toxic and harmless natural chemical extracted of vegetable oil. VG provide vapers a saturated taste experience during vaping. Compared with high PG, high VG has a softer throat sensation and can generate a lot of vapor. If you want pursue large vapor, you can choose high VG liquid But High VG intake can cause dry mouth and thirsty.How to deal with this symptom?


PG&VG has a wide variety of ratios,  the taste and throat sensation are mostly determined by this ratio. Different base ratios bring different taste and throat sensation. Choosing the right PG/VG ratio is important for your E-cig devices and flavor needs. Some devices only work for a specific PG/VG ratio to achieve the best experience. For example: vladdin's closed-type e-liquids is a specific proportion, which can achieves the best balance between flavors and vapor. The levels of nicotine salt is also divided into 18mg and 50mg to meet the needs of different consumers to the greatest extent.
