Opis

General description

Poly(ethylene glycol) (PEG) is a linear polyether of ethylene glycol (ethane-1,2-diol). It is soluble in water, benzene, ethanol, acetonitrile, and dichloromethane. However, it is insoluble in diethyl ether and hexane. This non-ionic polymer can exist in the monomer and aqueous phases.

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.
