Descrizione

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[1] can exist in the monomer and aqueous phases.[2]

Application

Poly(ethylene glycol) has been used:

to grow the crystals of HLA-A∗02:01-N222-230 LLLDRLNQL (pHLA) complex[3]
in the fabrication of ultrathin, free-standing, and porous polymer membranes for retinal tissue engineering
to grow the crystals of the C2c2-crRNA complex[4]
to grow the crystals of the apo-C2c2 thermolysin-resistant core[4]

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.
