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.

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.

Application

Poly(ethylene glycol) has been used:

to grow the crystals of HLA-A∗02:01-N222-230 LLLDRLNQL (pHLA) complex
in the fabrication of ultrathin, free-standing, and porous polymer membranes for retinal tissue engineering
to grow the crystals of the C2c2-crRNA complex
to grow the crystals of the apo-C2c2 thermolysin-resistant core

Biochem/physiol Actions

Poly(ethylene glycol) (PEG) is used in several pharmaceutical applications. This polymer occurs as a preservative and is used in biomedical applications like drug delivery systems, biosensing, and tissue engineering. PEG is also used in cosmetic ointments and creams. It is used as a binding and dispersing agent in chemical and other industries.
