About Polyethylene Glycol

Polyethylene Glycol, (C_2nH_4n+2O_n+1), is synthesized by ring-opening polymerization of ethylene oxide, in which the polymer chain has a reactive element on one end that reacts with another monomer. This synthesis process gives PEG a range of molecular weights and distributions from 300 grams per mole to 10,000,000 grams per mole. PEG can be a clear, thick liquid to a waxy solid synthetic resin. Polyethylene Glycol is colorless, inert, odorless, and non-volatile. PEG is biocompatible (it won’t damage tissues or cells), hydrophilic, dissolves readily in water without changing the color odor or taste and is nontoxic.

PEG has a vast amount of uses because of its unique molecular structure. It is often used in various products and industries as a surfactant, emulsifier, cleanser, lubricant and as a carrier for pharmaceuticals. It is found in many cosmetics and products used in daily life, including toothpaste, mouthwash and breath freshener, PEG is added to help consistency and increase shelf life. It has industrial applications to soften textiles, and in detergents and cleaners. In household items it can be used to add nonstick properties and is used as a coating on large industrial products. It’s used in medicinal products as a treatment for constipation and as lubricant in veterinary applications.
