A) Propylene Glycol (PG)
Propylene Glycol is a base liquid that is used to suspend your flavour. PG has no taste, odourless, and can be found in general products such as food and medicine. PG allows e liquid to be vaporised by the e cigarette atomizer creating a vapor that is inhaled.
B) Vegetable Glycerin (VG)
Vegetable glycerin, is a odourless and clear liquid produced from plant oils, typically palm oil, soy, or coconut oil. Vegetable glycerin has a number of valuable applications that include cosmetic products, foods, and as a replacement for alcohol in herbal and botanical tinctures. It also can be used as a food additive, for food flavourings and is contained in many food products sold.
These 2 solutions are used widely in society today. PG and VG are both base liquids that hold the flavour in your eliquid, and are both odourless and tasteless. PG is less viscous than VG and a higher PG .A higher VG content e liquid is more suitable to a sub-ohm vaping device or a dripper.
The other component that maybe added is nicotine (in varying concentrations). Nicotine is very addictive and non-smokers should not purchase Nicotine Juice Express’s nicotine products.
The final components used in E-liquid are food grade flavourings in very small quantities. These make inhalation more pleasant and are a very important component of vaping.
