Propylene glycol is a viscous, colorless liquid. It is almost odorless and has a faintly sweet taste. Its chemical formula is CH₃CHCH₂OH. As it contains two alcohol groups, it is classified as a diol. An aliphatic diol may also be called a glycol.Propylene glycol (IUPAC name: propane-1,2-diol) is a viscous, colorless liquid. It is almost odorless and has a faintly sweet taste. Its chemical formula is CH₃CH(OH)CH₂OH. 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^[6] are non-irritating and have very low volatility.^{[7]
The compound is sometimes called (alpha) α-propylene glycol to distinguish it from the isomer propane-1,3-diol, known as (beta) β-propylene glycol. Propylene glycol is chiral. Commercial processes typically use the racemate. The S-isomer is produced by biotechnological routes.}
