E-Liquids Ingredients

To produce E-Liquids, there are two key ingredients that should be present which are the following:

  1. Vegetable Glycerin (VG) –  it is a thick and sticky liquid that came from the palm plant. It is used in E-Liquid as a thickener. VG is often used as components for food production, medicines and cosmetics. It can also be used as a sweetener due to its sweet taste and food preservative. 
  2. Propylene Glycol (PG) – it is organic that we have been using for over a century. PG is used for flavouring and nicotine.  It is called as PG in the vaping world which is actually found in a lot of everyday products like medications, shampoo and toothpaste.

Each of an E-Liquid has a mixture of VG and PG with percentage of each should total to 100%. Mixes of PG and VG are recommended to be 50/50 which means 50% VG and 50% PG. There are also instances when the mixture is 70% VG and 30% PG and 60% VG and 40% PG. 


The Medicines and Healthcare products Regulatory Agency or MHRA mandates strict rules on selling E-Liquids in UK by testing and process of certification to make sure of its quality.

There is a larger EU rule that regulates vape products and a list of prohibited substances was presented through a law that was enforced by the MHRA in the Tobacco Products Directive or TPD. This parameter is also being carried out on the flavors and blends including a full toxicology and emission that should be presented prior to E-Liquid being sent to market.
