Monopropylene glycol is a colourless, viscous compound liquid, miscible with a large range of solvents including water, acetone and chloroform. It’s a common type of propylene glycerol, along with its brother chemicals dipropylene glycerol and tripropylene glycerol.The structure of monoropylene gycerol contains an asymmetrical carbon atom which means that there are two possible stereoisomers. It is produced through synthesis by the hydration of propylene oxide in a non-catalytic reaction, at 200 oC, and has a chemical formula of C3H8O2.This compound has a low toxicity rating if exposed to. Please note that it is NOT FOR HUMAN CONSUMPTION.
Monoglycerol Glycerol Uses
Monopropylene glycol has found its place in various industries due to its relatively low toxicity and safe use. It is available in two grades: first grade and industrial grade. Below are some ways in which these grades are commonly used.
As a humectant in food and food colourings (becoming E1520, an additive or ‘e number’)
As a solvent for pharmaceuticals.
As a moisturiser in many cosmetic products, such as shampoos, conditioners and make up
As a liquid component in e-cigarettes, also the process known as ‘vaping’.
To lower the freezing point of water – as a de-icer and antifreeze for cars, aircrafts, boats and runways
As an engine coolant
As a minor ingredient in the oil dispersant Corexit
As an intermediate in the production of paints, varnishes and printing inks
In the production of unsaturated polyster resins, such as bathtubs, tanks and pipes.
