POLYOX™ resins are nonionic polyethylene oxide solubility polymers. They are white to off-white, free-flowing hydrophilic powders supplied in a variety of viscosity grades corresponding to approximate molecular weight, ranging from 100,000 to 7,000,000 daltons.
 

Exceptionally unique polymer properties

POLYOX™ water soluble polymers for pharmaceutical applications possess a unique set of properties which allow for distinctive drug delivery solutions. 

• Very fast hydration makes them excellent choices for controlled release matrix tablets.
• Rapid swelling enables osmotic pump formulations which are perfect for narrow therapeutic window drugs or resolving food effects. Swelling properties also enable successful gastro-retentive dosage forms.
• Thermoplastic properties with a low melting point of 65°C means POLYOX™ can be extruded. Tablets can also be heat treated to make them crush resistant, a key tool in creating abuse resistant formulations.
• Superior adherence to mucosal membranes for mucoadhesive applications.
