Polyethylene Glycol (PEG): Complete Guide to Types, Applications, Specifications, and Buying Guide

Introduction to Polyethylene Glycol (PEG)

Polyethylene Glycol, commonly known as PEG, is a versatile synthetic polymer widely used across pharmaceutical, food, cosmetic, chemical, and industrial industries.

Due to its unique characteristics, PEG has become one of the most important multifunctional ingredients in global manufacturing.

Polyethylene Glycol is a polymer compound produced through the polymerization of ethylene oxide. Depending on its molecular weight, PEG can exist in different forms ranging from liquid products with low molecular weight to solid wax-like materials with high molecular weight.

The most common commercial grades include:

Each grade is designed for specific applications and must meet different quality requirements.

Choosing the correct PEG grade is essential because impurities, molecular weight, viscosity, and purity levels directly affect product performance.
