Application:
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.
