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.

Application

Poly(ethylene glycol) was used as hydrophilic carriers for characterizing the sirolimus solid dispersion nanoparticles.[1]

Biochem/physiol Actions

Polyethylene glycol (PEG) is a condensation polymer of ethylene oxide and water. It enhances the refolding of extracted proteins. This enables characterization of crystallized proteins.[2][3]

Preparation Note

Poly(ethylene glycol) dissolves in many organic solvents and is readily soluble in aromatic hydrocarbons. It also slightly dissolves in aliphatic hydrocarbons.
