1.Vegetable Glycerin (VG for short: Vegetable Glycerin):

Vegetable glycerin, like PG, is also a very widely used raw material in daily life. Careful friends look at the cosmetics, food, wine, and sugar around you. The ingredients marked on these packages are all “propylene glycol and glycerol”. Especially people who like to eat sweets, they also consume a lot of VG. Because the ingredients of these sweets such as cakes and biscuits mostly contain VG. The main role of VG in e-liquid is to produce mist.

VG will produce a lot of mist after heating. Generally, friends who use excessive smoke or dripping atomizers should know that if you want to increase the amount of smoke, you need to use refined oil to add a large amount of VG to produce ideal smoke . VG is highly hygroscopic and very viscous. If the fluidity of an e-liquid is very poor, it must have a high VG ratio. Such e-liquid has a lot of smoke, a slightly worse flavor, and a slightly weaker throat hit .

2.Propylene glycol (PG)

Propylene glycol is a common drug and food additive. It is hygroscopic, slightly sweet, colorless, odorless, transparent, and has good fluidity. The US Food and Drug Administration (FDA) defines PG as “generally safe for humans.” As one of the basic components of electronic vape juice, PG mainly functions as a carrier of flavor and enhances the taste of vape juice. After heating, it will produce a small amount of mist and have a certain throat hit.


Needless to say, nicotine can not only relieve cravings, but also produce a certain throat hit. Since pure nicotine is toxic when it comes in contact with the skin, it is generally dissolved in VG first.

4.Food flavors

Food flavors play a very important role in vape juice, which can be said to be the soul of vape juice. The flavor of vape juice is determined by the essence. The combination of different flavors and the ratio determine the flavor of a vape juice. In general, vape juice with a unique flavor has a very complicated flavor formula.

If smokers use e-cigarettes, they must choose good quality vape juice. The quality of vape juice will also affect the safety of electronic cigarettes. Buy vape juice and e-cigarette products made by regular manufacturers, so the safety is still guaranteed.
