Polyethylene Glycol Ether -PEG Grades

Production Detail:

Polyethylene glycol (PEG) is a versatile polyether being utilized in various applications, in particular in medicine. Polyethylene oxide (PEO) is another name for PEG. Typically, ethylene oxide macromolecules with molecular weights less than 20,000 g/mol are called PEG, while those having values above 20,000 g/mol are named PEO. It is reported that PEG is soluble in water, ethanol, acetonitrile, benzene, and dichloromethane, while it is insoluble in diethyl ether and hexane. PEG is available in different structures such as branched, star, and comb-like macromolecules. PEGylation is an attractive process in which PEG is bonded to another molecule, which is promising in therapeutic methods. PEG can hinder the protein adsorption which is essential in drug delivery to minimize the protein corona formation .

CAS No:9004-77-7

Synonym: PEG, Polyethylene Glycol Ether

Uses/Applications: Glycol ethers have many uses; these include use as solvents and as an ingredient in cleaning compounds, liquid soaps, and cosmetics. Acute (short-term) exposure to high levels of the glycol ethers in humans results in narcosis, pulmonary edema, and severe liver and kidney damage.
