Product Description of Polyethylene Glycol CAS#25322-68-3

Polyethylene Glycol is a high-purity industrial product with a minimum purity of 99%. It is available in multiple grades: AEO3 is a colorless liquid and AEO9 is a white paste. Both have a faint fatty odor and belong to nonionic surfactants. AEO3 has a melting point of 5–6 °C and a boiling point of about 290 °C. At 25 °C, its vapor pressure is below 0.1 hPa with a relative density of 0.925–0.940, featuring low volatility and stable physical properties. In terms of solubility, AEO3 is water-dispersible while AEO9 is freely soluble in water. Both dissolve readily in ethanol but are insoluble in kerosene. The product is stable under normal conditions; prolonged contact with strong acids at high temperatures should be avoided.
