PG versus VG
PG & VG for Vapers
Propylene Glycol is much thinner than vegetable glycerine. Its consistency is comparable to water. It wicks nicer and provides you with a stronger throat hit. PG tends to give you a genuine discernment of the flavors you are adding to your mixture.
Vegetable Glycerine is very thick compared to water and Propylene Glycol. It has a slightly sweeter taste, and will provide more “cloud” smoke than PG. Due to the viscosity of Vegetable Glycerine, it does not wick as well as Propylene Glycol and may wear down your atomiser quicker.
For someone who recently quit smoking, or is in the process of quitting, a higher
PG mix is often preferred, as you will get more of a throat hit often found in traditional cigarettes.
For someone looking to generate heavy “clouds”, or someone who may have allergens to propylene glycol, a higher VG mix will be preferred.
Many people in the process of giving up smoking, or who have already quit may find two juices useful. One juice with their preferred nicotine strength & one juice with zero nicotine strength. One will act as a “nicotine suppressant”, helping fulfill the nicotine craving. The other juice being that of 0 nicotine strength, which can be used as an all-day vape helping fulfill the habitual aspect of smoking.
What is Propylene Glycol (PG)?
Propylene Glycol is a colourless, almost odourless alcohol. It's technical name is propane-1,2-diol. This tells us it has a backbone of 3 carbon atoms., with 2 oxygen-hydrogen (OH) alcohol groups attached to the first and second.
Propylene Glycol is generally considered as safe and non-toxic. As a result it is therefore used in a wide range of consumer products.
Propylene Glycol has many useful properties, including being a humectant (keeping things moist), a preservative and a solvent. Due to this, it's used in cosmetics, pharmaceuticals, human and pet foods, food flavourings and many more products.
It's easy to vaporise, therefore used in Asthma inhalers, fog machines and e-liquids.
What is Vegetable Glycerine (VG)?
Vegetable Glycerine is also an alcohol. It's colourless, odourless and has a sweet taste. Vegetable Glycerine is much more viscous than Propylene Glycol. It also has 3 "OH" groups instead of 2, and it's technical name is propane-1,2,3-triol. It's sometimes referred to as Glycerol.
As with Propylene Glycol, Vegetable Glycerine is generally considered as safe and non-toxic.
Thanks to it's sweetness, it's role as a solvent, the fact that it's a preservative and it's ability to help things retain moisture, it also has many uses.
