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.
Intratec offers professional, easy-to-understand reports examining Propylene Glycol production.
