General Properties
Propylene glycol methyl ether, PM in short, is an organic solvent used in many different fields due to its fast vaporization and high surface resistance. It possesses two different functional groups and it has ligh, sweet, fruity scent.
Production
Propylene glycol methyl ether produced by adding propylene oxide methanol with a light alcali catalyst. Different catalysts yield different results in products.
Applications
Propylene glycol methyl ether is used as a conductor agent in surface coatings and printer inks. It also works as a solvent in pesticide and live stock businesses. For dyes, it improves fluidity, increases radiance and retards icing.
Aside from these, it is commonly used in domestic and industrial cleaning products. It is also used in printing and packing businesses.
Safety Measures and Toxic Levels
Propylene glycol methyl ether is extremely flammable and it is instable in high temperatures. Therefore, it must be stored in tightly closed containers and cool locations. It must be kept away from direct fire at all times.
Its toxicity is considered low on humans. If swallowed or inhaled in high amounts, it may cause vertigo and narcotic side effects. Its LD50 value on rodents is 4,016 mg/kg. It may be irritant for skin and eyes if exposed in high amounts. It does not pile up in nature and it is dismantled biologically.
