About Propylene Glycol. Propylene Glycol (a.k.a. Propane-1,2-diol) is a clear, colorless, non-corrosive but strongly hygroscopic difunctional alcohol, in such a way that it must be protected from exposures to the atmosphere. Unique among the glycols, propylene glycol has low toxicity for humans. It was first manufactured in 1859 by hydrolysis of propylene glycol diacetate, but it wasn’t until 1931 that it was first commercialized and used as a substitute for glycerol in pharmaceuticals. It is commonly used in unsaturated polyester resins, but also in foods, cosmetics, pharmaceuticals, and other applications.
Chemical Formula. C3H8O2
Commercial Grades. High-purity industrial grade (99.5 wt%); higher-purity; USP grade (99.5 wt%, higher quality standards in terms of some impurities)
Uses. Unsaturated polyester resins account for the majority of the commercial use of Propylene Glycol. Such resins, in turn, are used in thermoset composites. Other applications are for hydraulic fluids, rubber lubricants, and antifoam agents; as intermediates in urethane foams adhesives, coatings, elastomers, plasticizers, paint formulations and laboratory reagent. Particularly the U.S.P. grade Propylene Glycol is used in pharmaceuticals, cosmetics, and food additives.
- Propylene oxide + water (direct hydrolysis, coproduced with dipropylene glycol and tripropylene glycol)
- Glycerol + (hydrogenolysis)
- Propylene carbonate + carbon dioxide + methanol (transesterification, coproduced with dimethyl carbonate)

Derivatives. Propylene Glycol is used as raw material in the production of unsaturated polyester resins (coating grades, general grades, isophthalate grades).
