For chemical-technical applications.
1,2- Mono-propylene glycol or 1,2-propanediol known, is a water-clear, colorless and almost odorless polyhydric alcohol. It is highly water-absorbent and, because of its solubilizing and emulsifying properties, is often used as a carrier or solvent for dyes, flavors, emulsifiers and to dissolve enzymes. 1,2-Mono-Mono-Propylene Glycol is approved in the European Union as a food additive as E1520 for food supplements, among others. In the technical field , 1,2-mono propylene glycol in a water-substance mixture is used as antifreeze and as a coolant. Propylene glycol can substitute glycerol in various processing operations and vice versa. Due to its antimicrobial effect, additional preservatives can often be dispensed with when using 1,2-mono-propylene glycol.
1,2-propylene glycol, like ethylene glycol , is particularly suitable as a heat transfer medium in solar thermal applications. As a rule, it is used there as a mixture in the desired concentration. Unlike mono-ethylene glycol, 1,2-mono-propylene glycol is non-toxic and can therefore also be used in cooling systems that are used in the food industry.
Wash hands and other exposed body parts with mild soap and water before eating, drinking or smoking and when leaving the work area. Provide process area with good ventilation to prevent formation of vapors.

Contrary to popular belief, 1,2-mono prpylene glycol in its vaporized state can apparently even kill pneumococci (bacteria that cause pneumonia). These, at least, are the conclusions of a study conducted by Dr. Oswald Hope Robertson of Billings University in Chicago back in the 1940s. In this study, streptococci and pneumococci were exposed to steam and could thus be significantly reduced.
