Stability and storage conditions
Polyethylene glycol (PEG) is hygroscopic and should be stored in tightly closed containers, such as glass, plastic, aluminum, and stainless steel containers, in a cool, dry place, avoiding direct sunlight. PEG is a flammable liquid; therefore, fire safety regulations must be followed during storage and handling. Keep away from open flames, heat sources, and oxidizers.
