Description

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 2000 is a hydrophilic linear polymer that can be used as:

• An organic additive in the synthesis of metal nanoparticles to control the size and morphology of nanostructure.
• A carbon source to prepare acidophilic highly fluorescent carbon dots (CDs) via the one-pot hydrothermal method.
• A dispersion stabilizer to synthesize amorphous Fe₂O₃ nanoparticles by microwave irradiation method. During the synthesis, PEG-2000 inhibits nonhomogeneous precipitation to obtain homogeneous precipitation of the metal nanoparticles.
