Polyethylene glycol viscosity
WebPolyethylene 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 (Fig. 18.9) 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 … WebDec 29, 2024 · By investigating two different viscosity grades of polyethylene glycol (PEG), i.e., PEG 3000 and PEG 4000, and controlling the temperature of the microwave oven, it was possible to study the influence of both, temperature and viscosity, on the in situ amorphization of the model drug celecoxib (CCX) during exposure to microwave radiation.
