Castor oil polyoxyethylene ether EL-90 is a nonionic surfactant and is not classified as a hazardous chemical, so storage conditions are relatively lenient. However, the quality of the storage environment directly affects the product's service life and performance stability, so standardized storage management requirements should still be observed.
The product may solidify or become turbid in low-temperature environments. This is a normal physical change and does not indicate product deterioration. Normal performance can be restored by slowly raising the temperature within the recommended range (5°C–40°C) and stirring evenly. Direct flame heating of containers for thawing is strictly prohibited; indirect heating methods (such as a warm water bath) are recommended for slow melting.
Warehouse management should follow the "first-in, first-out" inventory turnover principle. Storage areas must have clear product identification and warning signs, keep passages unobstructed, and be equipped with eyewash stations and emergency flushing facilities to handle possible accidental contact.
| Item | Requirement |
|---|---|
| Storage Environment | Cool, dry, well-ventilated indoor warehouse, away from direct heat sources, direct sunlight, and high-humidity environments |
| Storage Temperature | Recommended 5°C to 40°C (solidification or turbidity at low temperatures is normal; recovery after heating and mixing) |
| Recommended Packaging Materials | Stainless steel, high-density polyethylene (HDPE), polypropylene (PP) |
| Incompatible Materials | Ordinary carbon steel (avoid prolonged direct contact) |
| Incompatible Substances | Strong acids, strong alkalis, strong oxidizers, hypochlorites, etc.; should be stored separately |
| Transport Classification | General cargo; not subject to special control under dangerous goods transport regulations |
During actual storage operations, containers should be resealed as soon as possible after opening to minimize prolonged exposure to air, preventing moisture absorption or contamination. If the product becomes viscous or solidified due to low temperature, use a warm water bath for indirect heating and stir evenly before use. For large-volume inventories, it is recommended to periodically inspect container seals and product appearance to ensure quality always meets usage requirements.
