Propylene Glycol 99.80% USP (GW)

What is Propylene Glycol? It is a viscous, colourless liquid. It is almost odourless and has a faintly sweet taste. Its chemical formula is C₃H₈O₂. As it contains two alcohol groups, it is classified as a diol. An aliphatic diol may also be called a glycol. It is miscible with a broad range of solvents, including water, acetone, and chloroform. In general, glycols are non-irritating and have very low volatility.

Frequent Uses

Polymerisation
Forty-five percent of propylene glycol produced is used as a chemical feedstock for the production of unsaturated polyester resins. In this regard, propylene glycol reacts with a mixture of unsaturated maleic anhydride and isophthalic acid to give a copolymer. This partially unsaturated polymer undergoes further crosslinking to yield thermoset plastics. Related to this application, propylene glycol reacts with propylene oxide to give oligomers and polymers that are used to produce polyurethanes.

Paints
Propylene glycol is used in water-based acrylic architectural paints to extend dry time which it accomplishes by preventing the surface from drying due to its slower evaporation rate compared to water.

Food manufacturing
In regulated amounts, propylene glycol is designated as safe for food manufacturing as an anticaking agent, emulsifier, flavor agent, humectant, texturiser, stabiliser, solvent, antioxidant, antimicrobial agent, and thickener.

Antifreeze
Propylene glycol is frequently used as a substitute for ethylene glycol in low toxicity, environmentally friendly automotive antifreeze. It is also used to winterise the plumbing systems in vacant structures.

Ecigs
Propylene glycol, vegetable glycerin, or a mixture of both, are the main ingredients in e-liquid used in electronic cigarettes. They are aerosolised to resemble smoke and serve as carriers for substances such as nicotine and flavourants.
