E-liquid FAQ's

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, Deserts, Sweets, Fruits, Cool/Menthols, Nasti type, Drinks, our house special Haloberri and many more! Another common ingredient is a nicotine solution which ranges in strength, whereas some e-liquids can be nicotine-free (depending on the users choice).

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.

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 nearly all 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 flavours. 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 Glycerin (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 pharmaceutical USP Grade PG and VG here at VapeBunkerUK ensuring the maximum safety without toxicity risk.

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. 

The USP stands for United States Pharmacopoeia. The EP stands for European Pharmacopoeia.

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 PGVG tends to generate more vapour and tends to linger moreVG generally gives a lesser throat hit and as a result is easier on the throat for all day vapingVG 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 VGPG tends to generate less vapour and disperses more quickly upon exhalePG generally gives a stronger throat hit but as a result can leave you with a dry throat with all day vapingA very small percentage of people exhibit a sensitivity to PG liquid and for that reason alone, prefer VG base instead.

(General comparisons are based upon equivalent VG liquid)

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.

Nicotine Salt FAQs

Nicotine salts are absorbed into the body more quickly than standard freebase nicotine, giving you a quick nic rush, and deliver a smooth throat hit. Nic salts are designed for use in low-power MTL (mouth-to-lung) & Pod devices. The next major advantage of using nic salt e-liquid is the nicotine blood absorption rate. It has been proven that nicotine salt vape juice will enter the bloodstream faster than traditional vape juice. Nic salts provide a blood absorption rate closer to an actual cigarette. Why do I want to vape on salts? Don’t let the name confuse you. The term “Nicotine salt” also known as nic salt just refers to the scientific definition. It doesn’t mean it’s infused with the tasty mineral you sprinkle on your mac and cheese. In chemical terms, a salt results when an acid reacts with a base. Simply put, nicotine salts are made by mixing pure nicotine (base) with certain kinds of acids. I know what you're thinking right about now, Acids? That sounds worse. Nicotine salts exist in tobacco, naturally. So, if you have smoked a cigarette you have experienced nicotine salt.

Nicotine, also referred to as freebase nicotine or nicotine liquid is directly extracted from tobacco. In this process, all the impurities found in tobacco are stripped away. Leaving you with nicotine in its pure form. This form of nicotine is used in almost all e-juices on the market today. Freebase nicotine has a high alkalinity with a PH level around 7-8. Why are you telling me this? Well, because the PH level directly correlates with the severity of harshness the vaper experiences during inhalation. The higher the nicotine strength, the harsher it becomes.

The creation of nicotine salt is achieved by strategically infusing specific acids to freebase nicotine. What this does is reduce the PH level of the nicotine solution, resulting in less irritation. Meaning you can vape higher nicotine salt strengths without that rough throat hit.

We already talked about one advantage that nic salts provide, a smoother hit allowing you to vape higher nicotine concentrations. The next major advantage of using nic salt e-liquid is the nicotine blood absorption rate. It has been proven that nicotine salt vape juice will enter the bloodstream faster than traditional vape juice. Nic salts provide a blood absorption rate closer to an actual cigarette.

This is beneficial to those trying to quit smoking because nic salt e-liquid is mimicking the effects of that cancer stick you're trying to put down. Therefore, if you are struggling with the transition to vaping because you are not getting the same effects as a cigarette then you might want to give nicotine salt e-juice a try.

When vaping nicotine salt e-liquid it is important to understand that the devices used to vape nicotine salt e-liquid will differ depending on the nicotine strength you choose. If you are simply looking to put down the cigarette than a higher nicotine salt strength such as 25mg or 50mg while using a low powered pod device is recommended. LNW's propriety Nicotine Salt formulation was designed to be used as Sub Ohm salts. If you like chucking clouds and getting tons of flavor with your high powered sub ohm device than we recommend turning it down a notch and using a lower nic salts e-liquid in the neighborhood of 6mg - 15mg. Higher nicotine strengths used in high powered devices will likely overwhelm you with too much nicotine so it is strongly advised you do not vape high strength nicotine salts e-liquid in high powered, sub ohm devices.

To wrap things up here is a summary of the pros and cons for vaping nic salt e-liquid.


− Smoother Hit

− Faster Absorption Rate

− Higher Nicotine Strengths Available


− Overwhelmed by too much nicotine

− Need different device for higher strengths
