General description

Polyethylene glycol (PEG) is a polyether compound with repeated ethylene glycol units[-(CH2CH2O)n].
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.

Application

Poly(ethylene glycol) has been used as a liquid medium to prepare shear thickening fluid (STF) by directly mixing it with fumica silica.

Biochem/physiol Actions

Polyethylene glycol (PEG) is a synthetic polymer and is used as an additive in food, cosmetics, and pharmaceuticals. It is also involved in biomedical applications like biosensing, imaging, and tissue engineering. PEG is used as a gold standard in bioconjugation and nanomedicine thereby increasing blood circulation time and improving drug efficacy. PEG-conjugated drugs are approved by the U.S. Food and Drug Administration (FDA). They are considered safe for use in humans. PEG reduces the liver uptake and repels protein adsorption, which makes it useful in nanocoating.
