Beschreibung

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.

Poly(ethylene glycol) (PEG) is a non-ionic hydrophilic polymer and is available in different molecular weights. It helps in the purification and crystal growth of proteins and nucleic acids. PEG and dextran together result in aqueous polymer two phase system, which is required for the purification of biological materials. PEG also interacts with cell membrane, thereby allowing cell fusion. It exhibitsstealth effect, prolonged blood circulation and excellent biocompatibility. PEG has an ability to elicit hypersensitivity reactions via stimulating complement pathway.

Application

Poly(ethylene glycol) has been used:

• as a constituent in the preparation of liquid desiccant solutions
• as a precipitating agent and additive in protein crystallization
• as a representative biocompatible polymer to decipher its interactions with cellular system at molecular level
