Uses	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.
Uses	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.
Uses	Used in conjunction with carbon black to form a conductive composite.1 Polymer nanospheres of poly(ethylene glycol) were used for drug delivery.2
Uses	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.
Uses	H2 histamine receptor antagonist, anti-ulcer agent
Uses	nonionic emulsifier
Uses	A polymer used to precipitate proteins, viruses, DNA and RNA
