The common ingredients in all e liquids


Whether your e liquid is commercially manufactured or in-house  DIY
They all share these universal ingredients.
Where things generally differ, relate to additional additives and compounds.

We’ll be looking into these in another section-


The 4 basic ingredients


Propylene Glycol Vegetable Glycerin 80 – 90 %

Concentrated Flavourings  8 – 10%

Nicotine 0% – 5%

Additional Ingredients – Additives & Compounds 0 – 2 %

Such as Sweeteners, Stabilisers and Alcohols (All FDA GRAS – Generally Regarded as Safe)

Propylene Glycol
A form of mineral oil, an alcohol produced by fermentation of yeast and carbohydrates.
It functions as a preservative in flavorings. Flavors without PG would not have a long shelf life.
e liquids with a higher PG content are preferred by many vapors as PG enhances flavour and acts as a carrier, and provides us throat hit too.

Vegetable glycerin
AKA glycerol is a clear, odorless liquid produced from plant oils, typically palm oil, soy or coconut oil.
It is considered a more natural, even healthier alternative to PG.
It creates far more vapor than PG and adds some sweetness too.
VG is extremely thick, which places an additional load on delivery systems.

This represents a small percentage of overall volume, but we understand its significance.
The percentage of nicotine is generally displayed on the bottles and measured in ML or MG.
For example- 16mg is 1.6% nicotine/milliliter.

When it comes to e liquid flavoring, it’s important to think in terms of flavor concentrates as opposed to flavor extracts or oils. BTW, the majority of flavorings are FDA approved.
(Never use food flavorings from supermarkets as they contain unwanted oils)

Additional Ingredients
Many e liquids contain some form of additional ingredients.
This is not to say that they represent a concern for the purists at heart,
nor are they anything other than what is found in many of our consumables.
Yes, some are common in tobacco cigarettes too.
