Castor Oil Polyoxyethylene Ether EL-60 should be stored in a cool, dry, and well-ventilated warehouse, keeping the container tightly sealed, avoiding direct sunlight and high temperatures. Under recommended conditions, the shelf life is typically 2 years.

Detailed Description

Castor Oil Polyoxyethylene Ether EL-60 (PEG-60 Castor Oil) is a chemically stable non-ionic surfactant, but to ensure the long-term optimal performance of the product, storage conditions are crucial. The product should be stored in a dedicated warehouse that is cool, dry, and well-ventilated, with an ambient temperature recommended to be not exceeding 40°C, and avoiding drastic temperature changes. The container must always be kept tightly sealed to prevent moisture absorption or ingress of impurities.

During storage, it should be kept away from heat sources, ignition sources, and incompatible substances (such as strong oxidizers), and avoid direct sunlight. Use rust-proof and corrosion-resistant storage containers, and ensure labels are clear and intact. It is recommended to follow the "First In, First Out" principle for inventory management, and it should not be stored together with food, beverages, or animal feed. The storage area should be equipped with spill containment materials and emergency eyewash and safety shower equipment.

Regarding shelf life, under the recommended storage conditions mentioned above, the typical shelf life of this product is 2 years. For products beyond the shelf life, it is recommended to re-test key indicators (such as appearance, pH value, emulsifying performance, etc.) before use to confirm they meet requirements.

Application Recommendations

Opened product should be used as soon as possible, and the container should be resealed immediately after each use to minimize contact with moisture and impurities in the air. If the product becomes cloudy or layered under low-temperature conditions, it can be placed in a warm environment to slowly return to room temperature and gently stirred evenly; this usually does not affect performance. If abnormal conditions such as significant color darkening, off-odor, or irreversible layering are observed, it is recommended to discontinue use and conduct quality testing.

Precautions

  • This product is a non-hazardous substance, but it should still be managed and stored according to chemical specifications.
  • Do not store together with food, beverages, or animal feed to prevent accidental ingestion.
  • The storage area should be equipped with spill emergency handling materials (such as sand, vermiculite, or other inert absorbent materials).
  • Products beyond their shelf life should not be discarded directly; they should be disposed of as chemical waste in accordance with local regulations.
