Propylene glycol - Wikipedia
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 CH 3 CH(OH)CH 2 OH. As it contains two alcohol groups, it is classified as a diol. An aliphatic diol may also be called a glycol.
