Descripción

General description

Polyethylene glycol (PEG) is a synthetic, hydrophilic, biocompatible polymer that has a wide range of uses in PEGylation, surface conjugation, nanoparticle coating, and crosslinking for hydrogels, etc. PEGs are made by polymerizing ethylene oxide via a ring-opening reaction to produce a wide range of molecular weights and molecular weight distributions (polydispersity).

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 6000 is a non-ionic surfactant that can be used as a structure-directing agent to prepare mesoporous γ-A_l2O₃. PEG 6000 induced the formation of the lamellate structure morphology of boehmite nanoparticles with improved textural properties such as high surface area, larger pore volume, and pore size. It is also used in drug formulations to enhance the dissolution rate of the poorly water-soluble drug molecule.[1][2] PEG-6000 can also be used in the purification of nucleic acids via the selective precipitation method. This approach is economically cost-effective and faster than the commonly employed chromatographic purification method.[3]
