- What is Propylene Glycol (PG)?
Propylene glycol is an organic compound. It is a colorless, nearly odorless, clear, viscous liquid with a faintly sweet taste that is very low in toxicity. It is a derivative of propylene oxide, which in turn is a derivative of propylene, and is used as an ingredient in many household products and cosmetics. It is also used widely in medicine, such as in asthma inhalers. Propylene glycol is mainly used in E-Cigarettes for its temperature lowering, water-retaining, and dissolving / bonding abilities in a non-toxic way.
- Why is Propylene Glycol Used in E-Liquid?
E-liquid contains vegetable glycerine(VG), which is quite thick. Propylene glycol is used to help "thin" the e-liquid and make it an easier consistency to load and evaporate. Because of PG, e-liquid is more easily absorbed by the fabric inside a cartomizer (the sealed e-cigarette cartridge found in products like the Optimal E-Cigarette Starter Kit and Clearomizer, and inside the clear or colored tank that holds e-liquid in an e-cigarette or e-hookah). The low density of PG also prevents any "gunk" from building up on the heating element of the atomizer.
- What else is Propylene Glycol Used For?
To give you an indication of the wide variety of products propylene glycol is used in, take a look at the following list:
Toiletries and cosmetics, like soap, deodorant, lotions, shampoo, lipstick and lubricants
Food, like salad dressings, soft drinks, cake mixes, fat-free ice cream and popcorn
Other household items, such as non-toxic automotive antifreeze
Used in asthma inhalers and fog machines at clubs/concerts
