Polyethylene Glycol (PEG)

Definition - What does Polyethylene Glycol (PEG) mean?

Polyethylene Glycol (PEG) is a chemical compound that contains polyether and is considered as an osmotic laxative. From petroleum manufacturing to medicine, every industry uses the chemical element. The polymer is quite familiar in the bio-medical field for the products that need different polymer chain lengths. The compound is either a low-melting solid or liquid in nature depending on the molecular weights. There are many different forms of PEG formed due to the presence of different types of initiators and the most often used initiator is methoxy polyethylene glycol.

Petropedia explains Polyethylene Glycol (PEG)

Polyethylene Glycol is formed due to the combination of ethylene oxide with water or ethylene glycol oligomers. Both types of catalysts, either acidic or basic can be used in the process. It has various clinical uses such as it can act as a vascular agent, tumor imaging agent, or lymphatic agent. Due to its high molecular weight, it is considered as the most powerful agent that can work against colorectal cancer in animals. Moreover, it is used in ointment bases, film coatings, and tablet binders. It is stored in jars and at temperatures of 20 degrees Celsius to 24 degrees Celsius.
