As a non-ionic surfactant, the storage conditions of Castor Oil Polyoxyethylene Ether EL-40 (PEG-40 Castor Oil) directly affect the quality stability and performance of the product. Under improper storage conditions (such as extreme high temperature, severe cold, or moisture), the product may undergo separation, turbidity, or deterioration, therefore storage specifications must be strictly followed.
The warehouse should be kept cool, dry, and well-ventilated, with impermeable flooring and equipped with dikes or containment facilities to intercept potential accidental spills. The product should always be stored in its original container or in compatible corrosion-resistant containers, which must be kept tightly closed to prevent moisture absorption or contamination. Containers should be placed on stable pallets or shelves to avoid excessive stacking that could lead to falling and damage.
Additionally, EL-40 should be stored away from drainage systems and water sources to prevent accidental leakage from entering the environment and causing water pollution. The storage environment must not contain strong oxidizers or strong acids to avoid harmful reactions. Although the product is not classified as flammable or explosive, it can assist combustion under fire conditions, so it must be kept away from sources of ignition and heat.
| Storage Parameter | Specific Requirement |
|---|---|
| Temperature Range | 5°C to 35°C (avoid extreme high temperatures and severe cold to prevent freezing or heat-induced separation) |
| Humidity Requirement | Dry environment, container kept tightly closed to prevent moisture absorption |
| Ventilation Condition | Storage area must have good ventilation |
| Light Requirement | Keep away from direct sunlight |
| Container Requirement | Original container or compatible corrosion-resistant container, kept tightly closed |
| Placement Method | On stable pallets or shelves, avoid excessive stacking |
| Prohibited Co-storage | Avoid storage with strong oxidizers and strong acids |
| Isolation Requirement | Keep away from sources of ignition, heat, drainage systems, and water sources |
| Floor Requirement | Impermeable floor, equipped with dikes or containment facilities |
| Environmental Warning | Storage area should have spill containment capability to prevent product from entering soil, sewers, or natural water bodies |
In application fields such as textile dyeing and printing, pesticide formulations, coatings and inks, metalworking fluids, and daily chemical products, EL-40 serves as a key emulsifying and dispersing auxiliary, and its performance stability is critical. It is recommended that users inspect the product appearance before use (normally a light yellow oily liquid to paste). If abnormal phenomena such as stratification, discoloration, or off-odor are observed, usage should be suspended and the supplier contacted for confirmation. After long-term storage, the product may show slight stratification; under the condition that it has not deteriorated, it can be properly stirred and homogenized before use.
