what is propylene glycol
Propylene glycol is a clear, colorless and hygroscopic liquid. Propylene glycol contains an asymmetrical carbon atom, so it exists in two enantiomers. The commercial product is a racemic mixture.Pure optical isomers can be obtained by hydration of optically pure propylene oxide.t is produced on a large scale and is primarily used in the production of polymers but also sees use in food processing as the E-number E1520. The compound is sometimes called Î±-propylene glycol to distinguish it from the isomer propane-1,3-diol (Î²-propylene glycol).
