What’s PG and VG?

Propylene Glycol (PG) and Vegetable Glycerin (VG) are two of the four main ingredients in almost all e-liquids, along with nicotine and flavourings. PG and VG are used to help distribute the flavour and nicotine throughout the e-liquid.


PG is an organic compound and is almost odourless and colourless. It has a low viscosity which means it flows easily, similar to water. PG absorbs flavours more easily than VG, and so using higher amounts of PG in e-liquids tends to create a more concentrated taste.


VG is an organic based substance derived from plant extracts. Coconut oil, palm oil and even soy can be used to extract VG. Whilst this substance is also odourless and colourless; it does have a very subtle sweet flavour. VG has a higher viscosity than PG, so higher levels of VG create a thicker vape cloud that some, more experienced vapers prefer. It also tends to produce a less intense hit on the throat when inhaled.
