E-Liquid Explained


Propylene Glycol and Vegetable Glycerin

The attached chart displays some of the qualities of Propylene Glycol (PG) and Vegetable Glycerin (VG), the two major constituents by volume of e-liquid or its commonly known name “e-juice”. Many E-Liquids are a mixture of both with nicotine and flavourings added. There are also juices that are predominantly PG or VG.


The chart shows PG at 100% on the left and VG at 100% on the right. In between are varying mixtures with half PG and half VG in the middle.

Throat Hit and Vapour Production

100% VG provides a high volume of vapour whereas 100% PG provides more of a sensation in the throat. In-between is some of each.


E-Liquid with a high percentage of VG will usually be thicker than those with a higher percentage of PG. The viscosity may effect how well the e-juice works with various equipment. Some vendors may use liquids other than PG to thin VG mixes.

Flavor and Sweetness

VG has it’s own property imparting some sweetness. However, VG tends to mute the added flavourings. A higher amount of PG in the mix tends to deliver flavors better. Other sweet flavourings can be added to high PG mixes to increase sweetness. The flavours are endless and you can mix and create your own when you have a clear understanding on exactly how the E-liquid is made.
