What exactly is an e liquid?
E liquid or E Juice is the liquid used in electronic cigarette (vape) devices. When heated, inhaled and then exhaled, the liquid becomes vapour.
What is in an e liquid?
E liquids contain up to 5 main components; Propylene Glycol (PG), Vegetable Glycerin (VG), Distilled Water (or AG), Flavour Concentrate, Nicotine or Nicotine Salt.
Propylene Glycol is a synthetic food additive that belongs to the same chemical group as alcohol. It is a colourless and odourless liquid that is a bit thicker than water. It tastes slightly sweet. Other names it is known by include; Monopropylene Glycol or Methyl Ethyl Glycol. Propylene Glycol is used in a range of industries from cosmetics and pharmaceuticals to agriculture, food and of course e-cigarettes.
Propylene Glycol is found in all e liquids and is usually in a higher percentage compared to Vegetable Glycerin. Propylene Glycol carries the flavour of the e liquid better and is known for creating a throat hit while vaping.
Vegetable Glycerin (also known as Vegetable Glycerine, Glycerol or Glycerine) is a liquid typically made from soybean, coconut or palm oils. It is odourless with a mild sweet taste. This liquid is a lot thicker than Propylene Glycol, it is more of a syrup-like consistency. Vegetable Glycerin is particularly popular in the cosmetic industry but has several other uses including medicinal products and e liquids.
Vegetable Glycerin in an e liquid creates a smoother vape and allows for more vapour while exhaling, also known as clouds.
Distilled Water is not found in every e liquid but is usually found in high Vegetable Glycerin e liquids. Some people are Propylene Glycol intolerant (find out more about PG intolerance here) and therefore vape 100% Vegetable Glycerin e liquids. As Vegetable Glycerin is thick and gloopy, it can cause your e-cigarette coils to clog and then burn. Adding 10-20% of distilled water to a high Vegetable Glycerin e liquid makes it thinner allowing it to run through e cigarettes more efficiently. Distilled Water mixed into Vegetable Glycerin is also known as Aqueous Glycerine (AG).
Flavour Concentrates are food grade flavourings that are also used in baking and added to other food related items including coffee. Flavour concentrates are different to syrups as flavour concentrates are the essence (flavour/odour/taste) but do not contain all the water and sugar which goes into making syrup. The majority of flavour concentrates are artificial however there are natural and organic flavours available too. You can check out our range of natural/organic flavours by clicking here.
Flavour concentrates are exactly what their name implies, flavour concentrates are what give your e liquid their flavour, taste and smell. They usually come in Propylene Glycol base this includes flavours from brands (flavour manufacturers) such as Capella (USA), Flavor Apprentice (USA) and Flavor West (USA). However here at Just Vape, we are the home of Vegetable Glycerin (VG) and Aqueous Glycerine based flavours. We are so proud to say we are the biggest VG base flavour supplier in the world with over 300 flavours to choose from. Our brands are manufactured and blended here in the UK. Check them out Kandi Hed and One Shot.
Nicotine (Free Base):
Nicotine is the addictive substance in cigarettes and some e liquids/shortfills. It is in liquid form and is available in Propylene Glycol or Vegetable Glycerin base. It is measured in Milligrams (MG). With most vapers vaping anywhere between 1MG and 12MG.
Some e liquids contain Nicotine Salt instead of Nicotine. They are still measured in the same MG strength as Nicotine and the salt version is also available in Propylene Glycol or Vegetable Glycerin base.
There are two types of Nicotine Salts. One is made with Benzoic Acid and the other is made with Salicylate.
Benzoic Acid is an antimicrobial food preservative also found in many plants and this is blended with freebase (liquid) Nicotine. The other type of Nicotine Salt is made the same way except Salicylate is added instead.
Salicylate is a natural chemical commonly found in fruits, vegetables, herbs etc. Both Nicotine Salt types creates a nicotine rush, as the nicotine is absorbed faster. Plus Nicotine Salts create a smoother vapour experience without the harsh throat hit.
