Highly water-soluble polymer with excellent biocompatibility and low toxicity.
Consistent molecular weight distribution (Mn ≈ 1900–2100 Da) ensuring reproducible performance in formulations.
Thermally stable up to 150 °C under inert atmosphere, supporting diverse processing conditions.
Non-volatile, non-ionic, and odorless—ideal for sensitive pharmaceutical and cosmetic applications.
Easily sterilizable by autoclaving or filtration without significant degradation.
Protein and peptide conjugation (PEGylation) to enhance pharmacokinetics and reduce immunogenicity.
Excipient in oral solid dosage forms, including as a binder, plasticizer, and solubilizer.
Component in topical ointments, creams, and gels for improved viscosity control and moisturization.
Carrier medium in controlled-release drug delivery systems and microsphere formulations.
Surface modifier for nanoparticles and liposomes to improve colloidal stability and stealth properties.
