E-liquid, also known as E-Juice, is the substance that fuels an electronic cigarette and creates the vapour that mimics the actual smoke from traditional cigarettes.
The liquid is slightly thicker than water and produces a denser vapour that doesn’t dissipate as fast as the steam produced by boiling water.
E-liquid clouds are the result of a process during which metal coils present in the e-cig’s atomiser are soaked in e-liquid and heated up through electrical current produced by a battery.
E-liquid is usually enriched with flavourings to enhance the vaping experience. VapeBunkerUK sources a huge array of flavours to accommodate the different tastes of e-cig users, including ranges from Slushys, Drops, Desserts, Sweets, Fruits, Cool/Menthols, Nasti type, Drinks, and our House Special Haloberri. Another common ingredient is a nicotine solution which ranges in strength, whereas some e-liquids can be nicotine-free (depending on the user).
The base ingredients of e-liquid consist of PG (Propylene Glycol), VG (Vegetable Glycerine), or a mixture of both, making up minimum 80% of the e-liquid’s total volume and weight.
What is PG?
Propylene Glycol is a petroleum by-product used in numerous food, beauty and medical supplies.
It is non-toxic, odourless and colourless, and is preferred by vapers who enjoy a ‘throat hit’, a strong sensation felt in the back of the neck similar to the sensation of smoking tobacco.
Being less viscous than VG, it also carries flavour and nicotine more effectively than VG, although a blend of PG and VG is always preferred.
Propylene glycol (PG) is thinner and has a stronger throat hit (TH). The more PG, the stronger the TH. Some people are sensitive and even allergic to PG, but it's not very common.
What is VG?
Vegetable Glycerine is a natural ingredient derived from vegetable oil. It’s sweet, non-toxic and very thick, making it difficult to smoke alone.
A high VG e-liquid provides a smoother vaping experience, and it is best suited for sub-ohm devices.
Though nicotine and flavourings are usually suspended in PG, it is due to VG’s sweet taste that manufacturers produce 100% VG e-liquids as well.
Vegetable Glycerine (VG) is what gives you vapour. The more VG, the more vapour produced. VG is thicker and sweeter than PG and makes for a smoother vaping experience. Because of this, it can mute some flavors. Again, some people can be sensitive or allergic, but it isn't very common.
Vegetable glycerine (VG) is more viscous than propylene glycol (PG). The higher the ambient temperature, the more the vegetable glycerine (VG) should be used.
It is important to know what the grade and the quality of the e-liquid base are when you purchase the e-liquid products. We use the best USP/EP Grade PG and VG ensuring the maximum safety without toxicity risk.
What is the USP/EP?
The USP stands for United States Pharmacopeia. The EP stands for European Pharmacopoeia.
VG Based E-liquid:
VG liquid mainly has a Vegetable Glycerine base, which is derived from vegetables. Whilst a VG liquid mainly contains VG, it also requires some PG content to work too. It is therefore the ratio of VG to PG that determines how it is classified - more VG content generally results in a liquid that will be classified as VG. Some VG liquids are classed as 'pure VG' but they will usually still contain at least 20% PG.
The general characteristics of VG based liquid are:
- VG is thicker than PG
- VG tends to generate more vapour and tends to linger more
- VG generally gives a lesser throat hit and as a result is easier on the throat for all day vaping
- VG tends to have a sweeter taste than PG
(General comparisons are based upon equivalent PG liquid)
PG Based E-liquid:
PG liquid has a Propylene Glycol base, which is used in food flavourings and in fog machines. Whilst a PG liquid mainly contains PG it also requires some VG content to work too. It is therefore the ratio of VG to PG that determines how it is classified - more PG content generally results in a liquid that will be classified as PG. Some PG liquids are classed as 'pure PG' but they will usually still contain at least 20% VG.
The general characteristics of PG based liquid are:
- PG is thinner than VG
- PG tends to generate less vapour and disperses more quickly upon exhale
- PG generally gives a stronger throat hit but as a result can leave you with a dry throat with all day vaping
- A very small percentage of people exhibit a sensitivity to PG liquid and for that reason alone, prefer VG base instead.

Please note that these are general guidelines and as usual, it really does come down to individual preference - experiment to find what suits you best.
