Propylene Glycol Monopropyl Ether (PGME): Properties, History & Applications

Propylene glycol monopropyl ether is a clear liquid that is stable under most conditions, although it is highly flammable. It is an organic compound that is a derivation of the simpler compound propylene glycol.

Discovery

• Propylene glycol monopropyl ether was discovered in the 1920s, but did not become popular for commercial use until the 1970s. Its use was popularized by the encouragement of the European Chemical Industry Council. Manufacturing of this chemical is executed by the reaction of propanol and propylene oxide.

Commercial Uses

• Propylene glycol monopropyl ether is a solvent for hard surface cleaners.

  Propylene glycol monopropyl ether is primarily used as a base ingredient in cleaning products. This is due to both its hydrophilic and hydrophobic properties. It is also a powerful grease and paint remover and serves as a solvent for hard surface cleaners.

Effects

• Propylene glycol monopropyl ether is a strong chemical compound, and any contact with the human body in its pure form has negative effects. Inhalation causes dizziness, drowsiness and headache. Ingestion can cause abdominal pain, diarrhea, and even unconsciousness.
