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 35000 (PEG 35000) is a hydrophilic polyether compound that can be used to synthesize:
  • Hierarchically structured silica monoliths for the fabrication of micro-bioreactors.
  • Micro-nanostructured PEG-DA (PEG-diacrylates) hydrogels for biomedical applications.

It can also be used as:
  • A template to prepare micro/mesoporous structure of silica by sol-gel process.
  • A stabilizing agent in the synthesis of metal nanoparticles.
