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 an eco-friendly, 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 glycol) (PEG) is a non-ionic hydrophilic polymer.

Application

Poly(ethylene glycol) has been used in the preparation of cryoprotective solutions.

Biochem/physiol Actions

Poly(ethylene glycol) (PEG) helps in the purification and crystal growth of proteins and nucleic acids. PEG also interacts with cell membrane, thereby allowing cell fusion.
