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.

Application

Polyethylene glycol 3000 can be used as:
  • A surface-modification agent in the synthesis of monodispersed magnetite colloidal magnetic nanoparticles.
  • A precipitating agent in the crystallization of oligoxyloglucan reducing-end specific cellobiohydrolase (OXG-RCBH) by the hanging-drop vapor diffusion method.
  • A solvent and phase-transfer catalyst (PTC) in the application of aqueous biphasic reactive extraction.
  • An additive in the preparation of polysulfone membrane to study the porometry.
