Polyether F-38 should be stored in a cool, dry, and well-ventilated warehouse. The recommended temperature range is 5°C–40°C, away from fire sources, heat sources, and strong oxidizers. The shelf life is typically one year.

Detailed Description

Polyether F-38 (Poloxamer 108) is a non-ionic surfactant with excellent chemical stability. It is stable under normal storage and handling conditions, non-flammable, has no auto-ignition temperature, and is not classified as a hazardous material. Proper storage ensures the product maintains optimal performance within its shelf life.

Temperature control is particularly important during storage. When the ambient temperature falls below 5°C, the product may solidify or become turbid. This is a normal physical change. Simply warm the material and stir evenly to restore it to its original clear liquid state, without affecting product quality. High temperatures should also be avoided; the upper storage temperature limit should not exceed 40°C.

From a chemical compatibility perspective, Polyether F-38 should be stored away from strong oxidizing agents, as contact with them may cause adverse reactions. Under normal storage conditions, the product does not decompose. However, if combustion occurs, it may produce carbon monoxide, carbon dioxide, and other irritating or toxic fumes.

Incompatible SubstancesKeep away from strong oxidizing agents
Packaging ConditionKeep container tightly closed to prevent moisture and contamination
Shelf LifeTypically one year under recommended conditions for unopened packaging
Hazard ClassificationNon-flammable, no auto-ignition temperature, non-hazardous material

Handling Recommendations

  • After each use, promptly reseal the packaging container to avoid prolonged exposure to air, which may cause moisture absorption or contamination.
  • Empty containers may contain residual product; do not use for other purposes without proper treatment.
  • If solidification or turbidity occurs during winter storage, gradually warm the material to above room temperature and stir evenly to restore normal condition.
  • It is recommended to follow the first-in, first-out inventory management principle to ensure the product is used within its shelf life.

Precautions

  • The warehouse should be equipped with eyewash stations and emergency shower devices to handle accidental exposure.
  • Do not discharge the product into drains or the natural environment. Disposal should be carried out by qualified professional agencies in accordance with regulations.
  • Although the product is low toxicity and non-flammable, general industrial chemical handling procedures should still be followed. Eating, drinking, or smoking is prohibited in the storage area.
