Description

General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. Polyethylene glycol (PEG) is a biodegradable polymer widely used in pharmaceuticals and cosmetics. Its non-toxic nature and versatility make it a sustainable choice, derived from renewable resources, contributing to greener product formulations. Click here for more information.

Poly(ethylene oxide) is a non-ionic hydrophilic linear polymer. It can be prepared by catalytic polymerization of ethylene oxide. Owing to its hydration and swelling properties, it is widely used in controlled drug delivery systems and bioadhesive materials.

Application

PEO can be used to:

Prepare polymer brushes with unique wormlike conformation which can be used in cancer drug delivery systems.
Synthesize polymer electrolytes for solid-state batteries and fuel cells.
Prepare biodegradable PEO/Ag nanocomposites forbiomedical and food packaging applications.

Features and Benefits

High water solubility
Non-toxicity
Rapid hydration
Insensitive to pH of the physiological system
