POLYOX™

Resins That Allow Distinctive Drug Delivery Solutions

What is it?

POLYOX™ resins are nonionic poly (ethylene oxide) polymers. They are white to off-white, free-flowing hydrophilic powders supplied in a wide variety of viscosity grades corresponding to approximate molecular weight, ranging from 100,000 to 7,000,000 daltons. POLYOX™ polymers possess thermoplastic properties, are fast-hydrating and very quickly form hydrogels. They are essentially tasteless, colorless, nonionic and non-caloric. Their unusual combination of properties makes them useful in a surprisingly broad array of pharmaceutical formulations such as controlled release formulations, tablet binding and mucosal bioadhesives.
