Polyethylene Oxide 400 (PEO 400) is a water-soluble synthetic polymer produced via anionic ring-opening polymerization of ethylene oxide. It serves as a high-purity oligomer with the molecular formula (C2H4O)n and CAS No. 25322-68-3. This low-viscosity grade acts primarily as a solvent, plasticizer, or binding agent in industrial formulations.
Store in tightly sealed containers at ambient temperatures away from moisture to prevent hydrolysis. While generally non-toxic, avoid inhalation of dust during handling. Not recommended for direct parenteral administration without specific pharmaceutical-grade validation.
