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.

Acidophilic highly-photoluminescent ionic liquid (IL)-modified carbon dots (CDs) were fabricated directly from polyethylene glycol-2000 (PEG2000N) by a simple one-step hydrothermal method in a system containing an IL (1-butyl-3-methylimidazolium bromide [C4mim]Br) and hydrochloric acid (HCl). In this process, PEG2000N works as
