CARBOWAX™ PEG 200E Polyethylene Glycol is the product of the catalysed reaction between ethylene oxide and water. The polymerisation reaction is controlled so that the average molecular weight is in the range 190–210. CARBOWAX™ PEG 200E Polyethylene Glycol, at room temperature, is a clear, hygroscopic liquid, which possesses a characteristic low vapour pressure and excellent lubricity. It is totally soluble in water and in most organic solvents except aliphatic hydrocarbons. At high temperatures and in the presence of air CARBOWAX™ PEG 200E Polyethylene Glycol will undergo decomposition. However, improved stability can be gained by the use of antioxidants. As CARBOWAX™ PEG 200E Polyethylene Glycol contains two terminal hydroxyl groups it can be used in polyurethane and esterification reactions.
