Application

Poly(ethylene oxide) serves as a versatile polymer with a range of applications in pharmaceutical formulations and other industries. It is a linear polymer composed of repeating ethylene oxide units, with molecular weights ranging from 200 to several million. The polymer's properties vary with molecular weight, influencing its applications and physical state. Poly(ethylene oxide) is water-soluble, nonvolatile, and generally nonirritant, making it suitable for use in ointment bases, suppositories, and controlled-release systems. It acts as an emulsion stabilizer, helps adjust viscosity, and enhances the solubility of poorly soluble compounds. Liquid grades (below molecular weight 600) are versatile solvents, while solid grades (molecular weight 1000 and above) are employed as plasticizers and lubricants in tablet formulations. Its adaptability extends to film coatings, where it improves the water permeability and flexibility of the film. Furthermore, poly(ethylene oxide) is used in innovative drug delivery systems, including microparticles and nanoparticles, demonstrating its broad utility and effectiveness as a polymer.
