Propylene glycol (1,2-propanediol), technically at least 99.5 % (5,15 kg) -

For chemical-technical applications.

Application

1,2-Mono-propylene glycol or 1,2-propanediol is a water-clear, colorless and almost odorless polyhydric alcohol. It is highly water-absorbent and is often used as a carrier or solvent for dyes, flavors, emulsifiers and for dissolving enzymes due to its dissolving and emulsifying properties.  In the technical field  , 1,2-mono propylene glycol is used in water-substance mixtures as antifreeze and as a coolant. Propylene glycol can substitute glycerine in various manufacturing processes 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. It is generally 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 food areas.

Precautionary measures

Wash hands and other exposed areas of the body with mild soap and water before eating, drinking or smoking and when leaving the workplace.  Provide process area with good ventilation to avoid formation of vapors.

Hazard statements

No labeling required.

Further information

Contrary to popular belief, 1,2-mono-propylene glycol can apparently even kill pneumococci (bacteria that cause pneumonia) when vaporized. At least these are the conclusions of a study by Dr. Oswald Hope Robertson from Billings University in Chicago, which he carried out back in the 1940s. Streptococci and pneumococci were exposed to steam and could thus be significantly reduced.

Storage

Store only in the original container in a cool, well-ventilated place. Keep container closed when not in use. Avoid direct sunlight.
