Castor Oil Polyoxyethylene Ether EL-80 should be stored in a cool (recommended 5–40℃, ideally 5–35℃), dry, well-ventilated warehouse, with the container tightly sealed, shelf life 24 months.

Detailed Instructions

Castor Oil Polyoxyethylene Ether EL-80 is a light yellow paste to solid at room temperature. The key storage conditions are to control temperature and prevent moisture. High temperature will cause the product to soften and cake, affecting performance; low temperature may harden the paste, increasing difficulty in handling. Therefore, the storage environment should avoid extreme temperatures, maintain a stable temperature in the warehouse, keep away from fire and heat sources, and avoid exposure to sunlight and rain.

This product is hygroscopic. After opening the container, it should be resealed as soon as possible to prevent absorption of moisture from the air which may degrade product quality. Also keep away from incompatible materials such as strong oxidizing agents, strong acids, and strong bases to avoid chemical reactions. The storage area should have an impermeable floor and be equipped with emergency spill containment facilities to manage potential packaging damage or leaks.

Under sealed and compliant storage conditions, the product shelf life is 24 months from the date of manufacture. It is recommended to follow the "first-in, first-out" principle to ensure inventory is used within the shelf life.

Transportation and Handling Recommendations

This product is a non-hazardous chemical and can be transported under general chemical conditions. Handle with care during loading and unloading to prevent packaging damage. If a leak occurs during transportation, collect with inert absorbent materials such as sand or sawdust, place in a sealed container, and dispose of waste according to local regulations.

Precautions

  • Do not leave the product container open; moisture absorption may affect emulsification performance and formulation effectiveness.
  • In low temperature winter conditions, the product may harden; before use, it can be restored to normal flowable state at 20–30℃, and should not be directly heated over an open flame.
  • Spills make floors extremely slippery; warning signs should be posted immediately and cleaned up.
  • Waste disposal must comply with local environmental regulations and must not be discharged directly into water bodies or soil.
