Propylene glycol(PG, CAS 57-55-6) is scientifically named as "1,2-Propanediol", and has a chemical formula of CH3CHOHCH2OH and a molecular weight of 76.10. There is a chiral carbon atom in the molecule. Its racemate is a hygroscopic viscous liquid and is slightly spicy. Propylene Glycol has a specific gravity of 1.036 (25/4 °C), a freezing point of-59 °C, and a boiling point of 188.2 °C, respectively 83.2 °C (1,333 Pa). Propylene Glycol is miscible with water, acetone, ethyl acetate and chloroform, and is soluble in ether. Propylene Glycol is soluble in many essential oils, but is not miscible with petroleum ether and paraffin oil. Propylene Glycol is relatively stable to heat and light, and is more stable at low temperatures.
