Description

Poly(ethylene oxide)

Poly(ethylene oxide) is a high-molecular-weight, water-soluble polyether used in pharmaceutical, biomedical, and industrial applications for its hydrophilic properties, biocompatibility, and ability to modify rheological behavior. Known for its exceptional solubility in water and organic solvents, it is widely used as a binder, film-former, matrix former, and viscosity modifier in both solid and liquid dosage forms. Poly(ethylene adipate) is

• A nonionic, water-soluble polyether polymer
• Used in tablets, ophthalmic preparations, controlled-release systems, and topical formulations
• Available in high molecular weight grades that offer extended drug release and mucoadhesion
• A low toxicity, non-immunogenic, and biocompatible polymer
• Is manufactured under Good Manufacturing Practice (GMP) certified conditions
• Supplied with complete regulatory documentation including Certificate of Analysis (CoA) and technical data

Poly(ethylene oxide) (PEO) is chemically identical to Poly(ethylene glycol) (PEG), differentiated primarily by molecular weight and intended function. It is commonly available in molecular weights ranging from 100,000 to over 5 million Da, which influences viscosity, swelling, and gelation characteristics.

In pharmaceutical and medical product development, Poly(ethylene oxide) is used in:

• Controlled-release oral dosage forms and osmotic pump tablets
• Ophthalmic inserts, bioadhesive films, and wound dressings
• Mucoadhesive delivery systems for buccal, vaginal, or rectal administration
• Matrix builders and viscosity enhancers in transdermal and topical gels
• Lubricants, stabilizers, and excipients in injectables and diagnostic reagents

The polymer’s ability to form highly viscous aqueous solutions and stable gels makes it valuable for modulating drug release, enhancing drug residence time at target sites, and improving texture and flow properties in semisolid formulations.

CarboMer supplies pharmaceutical-grade Poly(ethylene oxide) in multiple molecular weights and particle sizes to support a variety of formulation strategies. Blends or custom grades may be requested to meet application-specific performance needs.

The material is packaged in sealed, low-particulate, moisture-controlled containers. Available in R&D, pilot, and commercial-scale volumes. Minimum order quantities (MOQ), lead times, and documentation—including CoA and SDS—are provided upon request.

Each batch is tested for identity (IR, NMR), molecular weight distribution (GPC), viscosity, loss on drying, residue on ignition, and microbial purity. Certificates of Analysis (CoA), Safety Data Sheets (SDS), and full traceability documentation accompany every shipment.

As with all CarboMer hydrophilic polymers, Poly(ethylene oxide) is supported by regulatory expertise, formulation consultation, and reliable global distribution to ensure success in advanced pharmaceutical and medical product development.
