POLYOX™

Description

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 molecular weight, ranging from approximate 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.

Key Benefits:
• High solubility in water and polar solvents
• Very fast hydration, rapid swelling and hydrogel formation
• Molecular weights ranging from 100,000 to 7,000,000 daltons
• Hydrogen bonding functionality and good biocompatibility
• Thermoplastic polymer with low melting point of ~ 65°C
• Does not show a strong pH response due to their nonionic nature
• Tasteless, colorless, nonionic and non-caloric
