All our Flavour extracts are synthetic and of the highest of quality, generally most of our e-liquid have between 15% - 20% flavour added. The flavour extracts are identical that chefs use to flavour food, such as cakes, drinks, bakery products and like. So the flavours we use you probably already consume on a daily basis, all food safe and part of a modern existence.
The bulk of the e-liquid is made up of Vegetable Glycerin (Glycerine), it's a clear syrup-like liquid that has little taste and no odor. It’s obtained from vegetable fats found in carrier oils, such as soybean oil or coconut oil. In vaping this creates the vapor cloud on exhale and smooths the draw of vapor into your lungs.
Finally Propylene Glycol is added which has no odour or colour and works to maintain the flavour quality for longer periods of time, and also aids in the throat hit, which some users claim is similar to the sensation experienced when smoking. Propylene Glycol is an additive that is used in other foods such as coffee-based drinks, ice cream, whipped dairy products and soft drinks.
So typically the make up of an e-liquid is 20% flavour, 20% P.G. and 60% V.G.
Flavour = Taste
P.G. = Throat hit & preserves flavour
V.G. = Smoothness & vapour cloud.
The ratios can change, if you like less of a throat hit and want a smoother vape then you can adjust the V.G. up to around 80%, reducing the P.G. to compensate.
*note well; lowering the P.G. too much can reduce the flavour shelf life.
