Understanding PG and VG and How To Use It
Newcomers to vaping will no doubt have seen the PG and VG listed in e-liquid ingredients. It’s important to know what these substances are because they have an impact on your vaping experience.
All e-liquids comprise both VG and PG to differing equations. Getting the right measure of each substance will be a matter of personal choice, but this short guide will give you valuable insights before placing an order for e-liquids.
What PG and how is it used?
PG or Propylene Glycol is a liquid with no odour or colour. In vaping, PG carries the flavour and is the substance that gives you a ‘throat hit.’
Many vapers say the sensation from PG is parallel to smoking tobacco - but without the harmful side effects associated with traditional cigarettes.
Having said that, you may read stories in the mainstream media about PG being used in anti-freeze. These scaremongering campaigns are most likely sponsored by tobacco companies.
PG is used in non-toxic anti-freeze which is also used by food-processing manufacturers. It is not used in toxic anti-freeze. That contains a substance known as ethylene glycol (EG). PG and EG are not the same.
As a matter of fact, PG is found in many products that are classified safe:
- Oral hygiene products
- Pharmaceutical medicines
- Topical formulas
- Pet food
- Beauty products
- Baby wipes
What is VG and how is it used?
VG, or Vegetable Glycerine, is a derivative of vegetable oil and is used in vaping to thicken the e-liquid. It is the VG that produces the dense vapour clouds associated with sub-ohm vaping.
The VG content also has a slightly sweet taste and provides a vaping experience than PG. If you prefer sub-ohm vaping, e-liquids with a higher content of VG is advisable.
Choosing the right PG v VG ration for your e-liquids
When you’re choosing your first e-liquid, the best option is to go for a 50-50 split between PG and VG. This will give you an idea of what you most want from your vaping experience.
If you enjoy the sensation of smoking cigarettes, you may prefer the throat hit you can get with vaping. A higher PG percentage is better for this. Other vapers will find that too much PG will irritate your throat.
The typical symptoms you feel after smoking e-liquids with a higher PG ration are dry mouth, increased thirst and possible a sore throat. You may also notice symptoms of dehydration so drink plenty of water between vapes.
The advantages of a higher PG are they produce less plumage which is more acceptable for smoking e-cigarettes in public. If you want to produce vape clouds, a higher VG content is needed.
Higher levels of VG fluid also provide a smoother vaping experience albeit the flavour is less muted. Remember PG helps carry the flavour.
