What is Propylene Glycol?


Propylene Glycol according to the National Library of Medicine and Agency for Toxic Substances and Disease Registry, "is a synthetic liquid substance that absorbs water."

According to the FDA "Propylene glycol (C3H8O2, CAS Reg. No. 57-55-6) is known as 1,2-propanediol. It does not occur in nature. Propylene glycol is manufactured by treating propylene with chlorinated water to form the chlorohydrin which is converted to the glycol by treatment with sodium carbonate solution. It is also prepared by heating glycerol with sodium hydroxide." 

In the Code of Federal Regulation Title 21, Volume 3, SUBCHAPTER B--FOOD FOR HUMAN CONSUMPTION, Propylene Glycol is generally recognized as safe when the ingredient is used in foods at levels not to exceed current good manufacturing practice in accordance with 184.1(b)(1). For further detail check out the CFR - Code of Federal Regulations Title 21.

Propylene Glycol serves many different purposes, 5 of the main purposes are for non-toxic antifreeze, the food industry, pharmaceuticals, cosmetic products and electronic cigarettes. For more detail check out the chemistry blog by ReAgent  "5 Uses of Propylene Glycol" written by Lucy Bell-Young.
