Opis

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.
