Methoxy Polyethylene Glycol

Industrial Applications Methoxy Polyethylene Glycol (mPEG) is widely used as a surfactant, dispersant, solvent, and chemical intermediate in pharmaceutical, cosmetic, personal care, and polymer modification applications. It plays an important role in drug delivery systems, where it enhances solubility, stability, and biocompatibility of active ingredients. In coatings and polymer formulations, Methoxy Polyethylene Glycol is employed to improve dispersion, flexibility, and surface properties. It is also used as a lubricant additive, contributing to reduced friction and improved performance in industrial systems. Physical Properties Methoxy Polyethylene Glycol (mPEG) is a polyether compound consisting of repeating ethylene glycol units terminated with a methoxy group. It typically appears as a colorless to pale yellow waxy solid or viscous liquid, depending on its molecular weight, and is highly soluble in water, alcohols, and many polar organic solvents. Its physical properties, such as melting point and viscosity, vary with chain length. Grade Industrial Form Liquid Abbreviations mPEG
