New to the world of vaping and still trying to figure out the importance of PG and VG and the ultimate trade-off between the two? Well, we got you covered here!
When beginning with e-cigarettes, it is important to understand the device’s operation before differentiating between its ingredients. Broadly, an e-cig consists of a battery, atomizer, and a tank. The tank is then filled with your preferred e-liquid.
Upon powering the cigarette by inhaling, the atomizer heats up the eliquid. The e-liquid is soon converted into vapour by the application of heat. This vapour can then be inhaled and exhaled for a pleasant and flavourful hit. However, how strong the hit is, the flavour you experience and how much pleasure you get are vastly decided by the type of eliquid that you choose to go for.
This brings us to an obvious question – what is e-liquid all about? A bottle of eliquid consists of base, flavour concentrate and nicotine*. Our base will always include PG (Propylene Glycol) and VG (Vegetable Glycerine) which gives the e-juice its consistency.

Know What PG is all about
PG or Propylene Glycol is a petroleum by-product which has no odour or colour and is less viscous in comparison to VG. The throat hit provided by a high PG e-liquid is somewhat similar to the sensation fetched on smoking tobacco. It also holds flavour more efficiently than VG, making it the most popularly used suspension fluid for flavour concentrates and nicotine.
PG is commonly found in household items such as asthma inhalers, pet food, medical products and beauty products like make-up, shampoo and baby wipes. PG has been shown to be safe to ingest orally in studies and is generally regarded safe to be used as a food additive by FDA.
High levels of PG may irritate the throat and occasionally result into allergies. If you find this has happened to you we recommend using more VG in your liquid such as a 70%VG/30%PG mix. If you are still having an irritation you may have to mix your own flavours using 100% VG base.
Know What VG Is All About
VG (Vegetable Glycerine) is a natural chemical; it is mainly derived from palm oil. It has a slightly sweet taste and is thicker than PG. The hit of a high VG fluid is considerably smoother than that achieved with PG, which makes it ideal for sub-ohm vaping.
It is also widely used in sweeteners, beauty products, bubble bath and deodorant, pet food, baked goods and various dental care products. Try finding out the VGs in these products the next time you use them.
VG is normally recognized as safe by FDA and shown to possess low toxicity with less potential to irritate the skin or eye. However, if you are allergic to palm oil or coconut oil it is recommended watch your usage of VG. The most common side effects caused by vaping high VG containing eliquid are dry mouth, sore throat, and greater thirst, so consume lots of water and take a break from vaping if required.
The greater thickness of VG implies that it can lower the life of atomizers faster than PG based juice. High VG liquids clog up coils quicker and some kits may not work.
The Distinction between PG and VG E-Juice
PG and VG are odourless liquids which are mixed with flavour and nicotine* to produce e-juice. The difference between PG and VG is that PG e-liquid is thinner than VG due to its runny consistency. The low density of PG juice prevents the gunk from building up on the heating element of your vaporizer as quickly as it does with the thicker VG. PG is a tasteless and odourless substance, thus it doesn’t affect the flavour of the e-juice.
PG is also a strong humectant, so apart from drying your mouth and throat due to its consistent use, it also imparts a stronger throat hit. The downside is that PG has been shown to cause an allergic reaction among a few e-cig users. If you feel uncomfortable after vaping PG e-juice, you should discontinue using it at once and shift to vegetable glycerine.
VG e-liquid, on the other hand, has a slightly sweet taste and is less allergy causing than PG. The throat hit with VG is comparatively less as compared to its counterpart. The upside is that VG e-juices create considerably more vapour due to its thick consistency.
The Better Deal between PG and VG
If you want a great throat hit and high flavour, then go for a PG e-liquid. If you are a lover of clouds and want greater vapour, VG will make your atomizer do it for you. The normal concept is that the greater VG eliquid you intake, the lesser the throat hit.
The vaping community has mixed views regarding VG vs. PG e-liquid preference. Some vapers are in love with deep throat hit with more flavour and vapour provided by PG, while others enjoy the sweet and heavy plumes of vapour delivered by VG.
We recommend a 50/50 base mix for regular vaping, this provides a nice throat hit and sufficient vapour. For sub ohm vaping as this provides as stronger throat hit you don’t require as much PG in the liquid. We recommend a 70VG/30PG mix.
