What Does PG /VG Mean?

Propylene Glycol is a food grade chemical and is a key ingredient as an additive in various medicines and many food products. Propylene glycol is used in food products as a flavoring carrier, is non-toxic, and is an ingredient in products including food coloring and many types of flavouring. A base made of 100% PG is not as smooth as a base made of a PG/VG blend.

What is Vegetable Glycerin?

Vegetable Glycerin is a thick, sweeter tasting, vegetable based liquid used in electronic cigarettes and personal vaporizers. A base made of 100% VG is often very thick and hard to absorb effectively, when compared to a PG/VG mixed base.

What are all of those choices when ordering e-liquid?  40/60, 20/80, 50/50??  What does it all mean??

E-liquid is a mixture of varying amounts of about 4 different ingredients.  Nicotine, PG (propylene glycol), VG (vegetable glycerin) and flavoring.  Some liquids can have additional ingredients, but for the most part, these are the main ingredients to all e-liquid.

The amount of nicotine is dependent on the strength of nicotine in your e-liquid, but let’s say it is around 10% nicotine.  Somewhere around 10% of your e-liquid will be flavoring.  That leaves 80% of the liquid in your bottle for fillers, which dilute the flavoring and the nicotine.  This is where PG and VG come in, and depending on how you like your vape, that determines the percentage of PG and VG in your e-liquid.

Vegetable Glycerin (VG) is a thick, sweet liquid.  VG produces luscious clouds of vapor.  VG also imparts a sweeter taste to your liquid.

Propylene Glycol (PG) is a much thinner tasteless liquid.  PG produces more of a “throat hit” than VG does, which simulates the feel of smoking better.  PG also has a higher rate of sensitivity for some people, meaning that some people just can’t use PG in their vape.
