PG and VG – The differences

Difference between pg and vg

The building blocks of e-liquid

All e liquid comes in a base mixed primarily with PG and VG. Obviously, additional ingredients such as flavourings and sweeteners are present. One of the most important choices a vaper makes is determining their PG/VG ratio’s and preferences.  One’s desired percentages are made purely from trial and error however, I suggest a starting point of 50/50.

PG – Propylene Glycol
Propylene Glycol is an organic compound produced from Propylene Oxide. It is colourless, nearly odourless, and retains low viscosity. Food grade Propylene Glycol is recognised safe by the U.S. Food and Drug Administration. The main applications for Propylene Glycol are solvents, humectants, preservatives in food, tobacco products, pharmaceutical products and e liquids.

VG – Vegetable Glycerin
Vegetable Glycerin is a natural liquid generally extracted from plant oils such as soy, coconut and palm oil. It is typically clear and odourless; in some cases sweet and relatively viscous. Like Propylene Glycol it is considered safe by the U.S. Food and Drug Administration. The main applications of Vegetable Glycerin are cosmetics products, food production, and e liquids.

Although VG is fairly thick and places an additional load on the atomiser coils, most of today’s replacement coils are certainly up for the challenge. My mixes tend to be around 25% PG and 75% VG and I’m using Clearomisers daily with no performance issues at all.
