Propylene glycol, aswell alleged 1,2-propanediol or propane-1,2-diol, is an amoebic admixture (a diol or bifold alcohol) with blueprint C3H8O2. It is a colorless, about odorless, clear, adhesive aqueous with a faintly candied taste, hygroscopic and miscible with water, acetone, and chloroform.
Propylene glycol is a clear, achromatic and hygroscopic liquid. Propylene glycol contains an absurd carbon atom, so it exists in two stereoisomers. The bartering artefact is a racemic mixture. Authentic optical isomers can be acquired by hydration of optically authentic propylene oxide.
The freezing point of baptize is depressed if alloyed with propylene glycol attributable to the furnishings of dissolution of a solute in a bread-and-butter (freezing-point depression); in general, glycols are non-corrosive, accept actual low animation and actual low toxicity (however, ethylene glycol is baneful to bodies and abounding animals).
