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:
It can also be used as:
- Hierarchically structured silica monoliths for the fabrication of micro-bioreactors.
- Micro-nanostructured PEG-DA (PEG-diacrylates) hydrogels for biomedical applications.[1]
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.[2]
