Beschreibung

General description

Polyethylene glycol (PEG) is a versatile and non-ionic polymer[1] commonly used in a range of industrial and pharmaceutical applications due to its low toxicity, hydrophobic nature, and semicrystalline structure. It is made up of CH₂-CH₂O repeating units and its ability to exist in both monomer and aqueous phases at high temperatures[2] makes it valuable for a range of research applications.

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.
