What Is Vape Liquid?

Vape liquid also known as e-liquid is the core component of an e-cigarette, when inhaled it produces clouds of vapour. In its simplest form, vape liquid consists of four main ingredients: nicotine, flavour, diluent and water. Let’s take a look at some of these e-liquid ingredients a little more closely below.

Propylene Glycol (PG):

Our Propylene Glycol is high-quality pharmaceutical grade. It helps to produce what we refer to as a ‘throat hit’ in combination with nicotine and flavours. Propylene Glycol is the other key diluent that is used to carry the nicotine and flavour when heated to deliver a throat hit like smoking. The higher the PG content the stronger the flavour and throat hit. Learn more – What is PG and VG?

Vegetable Glycerine (VG):

Glycerine is included to help produce more dense clouds of vapour and adds a complimentary sweetness and smoothness to the e-liquid. It is also what produces the vapour when heated. High VG content produces thick and large clouds of vapour.

This type of vape juice is designed to be used with high-powered mod kits, utilising low-resistance coils that can absorb thicker e-liquids to produce large clouds. Vape juice with a higher PG content is suited towards mouth-to-lung vaping. this technique closely resembles the most common method of smoking. MTL vapers require e-liquid with a high PG content as too much VG will dilute the flavour and nicotine resulting in a weak hit. Plus, the coils designed for MTL vaping have a high resistance meaning they will struggle to wick thicker e-liquid.

Aqueous Glycerine (AG):

Our Aqueous Glycerine is high-quality pharmaceutical grade and is diluted with de-ionised water to keep the e-liquid viscous, which can help the electric vape coils more easily absorb the e-liquid through the wicking material.

The diluents found above can be present in e-liquids at different ratios, as a rough guide the higher the PG content the more throat hit, and the higher the VG/AG content the more vapour is produced.

Nic salt is designed to replicate the natural salt found in tobacco leaves and delivers a vaping experience that closely matches smoking. This type of vape juice provides a sharper rush of nicotine with a smoother throat hit than freebase e-liquid, even at higher strengths. Nicotine salts are designed for MTL (mouth to lung) vapers, especially those who require higher-strength e-liquid but find regular vape juice too harsh. Popular choices include Maryliq, Elfliq, ELUX Legend Nic Salts, and Crystal Bar Liquids.

Nicotine by itself has no flavour, the taste comes from the flavour of the vape liquid within the propylene glycol (PG) content. We offer a wide range of flavours including tobacco, menthol, fruit, drink and cocktails, sweet and desserts, and more. We believe we produce and offer the highest quality product ranges with the finest tasting flavours designed to create the best vaping experience.

Yes, vape liquid can be taken on a plane. However, each bottle must contain no more than 100ml of e-liquid and should be displayed and sealed properly for security. 

There are no restrictions on how many e-liquids you can take in your hold luggage. Please note you cannot carry disposables or vape kits in the hold, as they feature lithium-ion batteries. Alternatively place them in your hand luggage. Typically, most airlines have a limit on how many batteries you can carry, this is generally between 15 and 20.

Vape liquid has a shelf life of 1-2 years when stored in a dark and cool place. However, once a bottle has been open it should be used within a few months to enjoy the best flavour.
