Product Description

Methxypolyethylene Glycol (MPEG) Description

Methxypolyethylene Glycol (MPEG) is a chemical compound derived from polyethylene glycol (PEG) with a methxy group at one end of the polymer chain. It is a nonionic, water-soluble polymer with excellent biocompatibility, low toxicity, and versatility due to its chemical structure. MPEG is widely used in various industries, including pharmaceuticals, cosmetics, and industrial applications, as a thickening agent, dispersant, or surfactant.
