1-Propylene glycol

Propylene glycol is less toxic than ethylene glycol and is often labeled as a nontoxic antifreeze. This material is used in arenas other than the auto industry, such as water pipes and food processing. Propylene glycol will break down more readily and yield organic acids (formic, carbonic, and oxalic) upon exposure to excessive heat and air. The material will turn reddish in color upon breakdown. [Pg.108]

Propylene glycol (boiling point 189°C, density 1.0361) is produced by hydration of propylene oxide in a process similar to that for the production of ethylene glycol by hydration of ethylene oxide. [Pg.434]

Unsaturated polyester resins account for the majority of the commercial use of propylene glycol. Other uses include food, cosmetics, pharmaceuticals, pet food, and tobacco humectants. [Pg.434]

Sodium PCA is hygroscopic, attracting moisture from the air. It is used as a humectant (moisturizer) for hair- and skin-care products. It is a stronger hydrating agent than the traditional compounds used for this purpose, such as glycerin, propylene glycol, or sorbitol. [Pg.126]

Used as fibres, particularly in textiles and film. Many other polyester polymers are of importance, e.g. unsaturated polyester resins from phthalic anhydride, propylene glycol and maleic anhydride used with reinforcement in boats, cars, etc. (alkyd resins). U.S. production 1983 1-7 megatonnes. [Pg.320]

Ethylene glycol and propylene glycol are common names for these two diols and are acceptable lUPAC names Aside from these two compounds the lUPAC system does not use the word glycol for naming diols... [Pg.634]
