Polyethylene glycols are a family of linear polymers formed by a base-catalyzed condensation reaction with repeating e thylene oxid e units being added to ethylene. The molecular formula is (C2H4O)multH2O where mult denotes the average number of oxyethylene groups. The molecular weight can range from 200 to several million corresponding to the number of oxyethylene groups. The higher-molecular-weight materials (100 000 to 5 000 000) are also referred to as polyethylene oxides. The average molecular weight of any specific polyethylene glycol product falls within quite narrow limits (°5%). The number of ethylene oxide units or their approximate molecular weight (e.g., PEG-4 or PEG-200) commonly designates the nomenclature of specific polyethylene glycols. Polyethylene glycols with amolecular weight less than 600 are liquid, whereas those of molecular weight 1000 and above are solid. These materials are nonvolatile, water-soluble, tasteless, and odorless. They are miscible with water, alcohols, esters, ketones, aromatic solvents, and chlorinated hydrocarbons, but immiscible with alkanes, paraffins, waxes, and ethers.
Polyethylene Glycol is a binder, coating agent, dispersing agent, flavoring adjuvant, and plasticizing agent that is a clear, colorless, viscous, hygroscopic liquid resembling paraffin (white, waxy, or flakes), with a ph of 4.0-7.5 in 1:20 concentration. it is soluble in water (mw 1,000) and many organic solvents.
polyethylene glycol (PEG) is a binder, solvent, plasticizing agent, and softener widely used for cosmetic cream bases and pharmaceutical ointments. Pegs are quite humectant up to a molecular weight of 500. Beyond this weight, their water uptake diminishes.
Used in conjunction with carbon black to form a conductive composite.1 Polymer nanospheres of poly(ethylene glycol) were used for drug delivery.2
Poly(ethylene Glycol) molecules of approximately 2000 monomers. Poly(ethylene Glycol) is used in various applications from industrial chemistry to biological chemistry. Recent research has shown PEG m aintains the ability to aid the spinal cord injury recovery process, helping the nerve impulse conduction process in animals. In rats, it has been shown to aid in the repair of severed sciatic axons, helping with nerve damage recovery. It is industrially produced as a lubricating substance for various surfaces to reduce friction. PEG is also used in the preparation of vesicle transport systems in with application towards diagnostic procedures or drug delivery methods
