Description

General description

Polyethylene glycol (PEG) is a polymer of ethylene oxide and water, obtained upon condensation. PEGs are susceptible to oxidative degradation in the presence of air. Minimizing the exposure of PEG to elevated temperatures and/or exposure to oxygen or addition of an antioxidant can limit the amount of degradation. PEGs do not hydrolyze or deteriorate upon storage. PEGs do not support the growth of molds.

Polyethylene glycol (PEG) is used in detergents, emulsifying agents, soaps, metal costing process, pharmaceutical preparations and cosmetics. PEG is commonly used as a lubricant. It′s application is also observed in chromatographic stationary phases. PEG prevents crystal formation in emulsions.

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.
