Overview
Polyethylene Glycol 6,000, commonly referred to as PEG 6000, is a polyether compound that is used in a wide variety of fields including pharmaceutical manufacturing as an excipient and active ingredient. Due to its low toxicity it can be used as a lubricating coating for various surfaces in aqueous and non-aqueous environments, a reagent in biochemistry to create very high osmotic pressures, a polar stationary phase for gas chromatography and as a binder.
