Poly(ethylene glycol) monomethyl ether [MW 1,900]

Poly(ethylene glycol) monomethyl ether (PEG-MME) is a nonionic, water-soluble polymer with a methyl-terminated end group, providing excellent solubility, low toxicity, and biocompatibility. The unique hydrophilic nature of PEG-MME makes it an essential component in drug delivery systems, coatings, and polymer modification applications requiring controlled surface properties and steric stabilization.

Applications:

Pharmaceutical & Drug Delivery: Used in PEGylation of proteins and nanoparticles to enhance biocompatibility and circulation time.

Coatings & Surface Treatments: Provides anti-fouling and hydrophilic properties in medical and industrial coatings.

Personal Care & Cosmetics: Functions as a humectant and stabilizer in lotions, creams, and emulsions.

Polymer Modification: Enhances flexibility and processability in biodegradable polymers and hydrogels.

Nanotechnology & Biotechnology: Serves as a steric stabilizer in colloidal dispersions and nanoparticle formulations.
