What’s In E Liquid?

E-cig Liquids

The market for electronic cigarettes is growing at an amazing rate and it has already become a multi-billion industry worldwide.

But what are the ingredients in E Liquid?

Actually, there are only four basic ingredients:

  • 84.6 – 92 percent Propylene Glycol and Glycerol
  • 0 – 5.4 percent Nicotine
  • 8 – 10 percent Flavorings
ingredients in ecig Liquid

Propylene Glycol (PG)

Propylene Glycol is used as a carrier for the nicotine and flavorings; this is what produces the vapor upon exhaling.

The U.S. Food and Drug Administration (FDA) states: “Propylene glycol is metabolized
by animals and can be used as a carbohydrate source . . . There is no evidence in the available information on propylene glycol . . . that demonstrates,or suggests reason to suspect, a hazard to the public when they are used at levels that are now current or that might reasonably be expected in future.”

Vegetable Glycerol (VG)

Vegetable Glycerol can be used as an alternative carrier, or it can be combined with PG.

VG is a plant-based carbohydrate and, also produces abundant vapor upon exhaling. VG safety is well accepted and studies demonstrate that it is non-carcinogenic. Both PG and VG are widely used in many industries,including pharmaceutical, cosmetic and food. The FDA has designated both PG and VG as ‘Generally Recognized as Safe’ for oral or dermal use.


Nicotine is a naturally occurring alkaloid found in tobacco plants and added to E Liquid. Although Nicotine can be synthetically manufactured, the nicotine in electronic cigarettes is all extracted from tobacco plants.

Nicotine has addictive properties, but it also has a stimulant effect on the brain, activating receptors and releasing chemicals associated with mood changes. Actually, nicotine acts as both a mild stimulant and relaxant.


One advantage of E Liquid is that the basic nicotine can be supplemented with other flavors, or can be replaced altogether. Flavors range from the simple, like menthol, to exotic versions of fruits and alcohol – and even chocolate!
