Polyethylene Glycol (PEG): Molecular Weight-Driven Applications in Pharmaceuticals, Cosmetics, and Advanced Materials

Polyethylene Glycol (PEG) is one of the most versatile and widely used synthetic polymers in modern industry. Known for its excellent water solubility, biocompatibility, low toxicity, and minimal immunogenicity, Polyethylene Glycol has become a critical material in pharmaceuticals, personal care, and advanced material science. Derived from the polymerization of ethylene oxide, Polyethylene Glycol is available in a broad molecular weight range, typically from 200 Da to over 20,000 Da, enabling highly customized functionality across applications.
