1,2‐Propanediol, [57‐55‐6], propylene glycol, HOCH2CH(CH3)OH, is very similar to ethylene glycol in its physical and chemical properties (→ Ethylene Glycol). The first reported description of 1,2‐propanediol was by Wurtz in 1859 1.

Industrial‐scale synthesis of 1,2‐propanediol from propylene oxide (→ Propylene Oxide) and water began in the 1930s. Current production uses this same process, which leads simultaneously to di‐ and tripropylene glycols. The worldwide capacity for 1,2‐propanediol was predicted at 2.56 × 106 t in 2017 2.

1,2‐Propanediol finds use in diverse applications, such as unsaturated polyesters (→ Polyester Resins, Unsaturated) for thermoset composites, food chemistry, food processing equipment, cosmetics, pharmaceuticals, as well as deicers and automotive antifreeze components (→ Antifreezes).
