Stability and Storage Conditions

Polyethylene glycol (PEG) is hygroscopic and should be stored in airtight 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 should be followed during storage and handling, keeping it away from open flames, heat sources, and oxidizers.
