Isotridecanol polyoxyethylene ether E-1310 is a nonionic surfactant (fatty alcohol polyoxyethylene ether type) with relatively stable chemical properties, but it still needs to be stored strictly according to specified conditions to maintain optimal performance. Improper storage may lead to moisture absorption, stratification, microbial growth, or degradation of active ingredients, thereby affecting its core functions such as emulsification, wetting, and dispersion.
Regarding shelf life, the product is usually accompanied by a certificate of conformance or quality inspection report at the time of shipment, which clearly indicates the production date and expiration date. Nonionic surfactant products under proper storage conditions generally have a shelf life of 2 years. For products beyond the shelf life, it is recommended to conduct small-sample performance verification to confirm that key indicators (such as pH value, cloud point, hydroxyl value, etc.) have not deviated significantly before further use; otherwise, they should be disposed of as waste.
| Storage Parameter | Specific Requirements |
|---|---|
| Storage Temperature | 5°C to 40°C (avoid extreme high or low temperatures to prevent solidification or excessive thickening) |
| Storage Environment | Cool, dry, well-ventilated dedicated warehouse, away from heat sources and direct sunlight |
| Container Condition | Keep container sealed to prevent moisture absorption |
| Recommended Packaging Material | Stainless steel, polyethylene (PE), polypropylene (PP) |
| Prohibited Packaging Material | Aluminum, uncoated carbon steel containers |
| Incompatible Substances | Strong acids, strong bases, oxidizing agents |
| Segregation Requirements | Keep away from food, beverages, and animal feed |
| Floor Measures | Equipped with spill containment measures and collection facilities to prevent leakage spread |
| Shelf Life Reference | Typically 2 years (subject to the factory certificate of conformance; no separate official shelf life parameter is available) |
In actual production and use, it is recommended to follow the "first-in, first-out" principle, prioritizing the use of earlier batch products. After opening and taking materials, the container should be immediately resealed to minimize product exposure to air, avoiding moisture absorption and contamination. If the product undergoes solidification or stratification at low temperatures, it can be slowly warmed to room temperature (20°C–30°C) using a warm water bath before use, and stirred evenly as appropriate. Do not use direct flame or high-temperature steam for heating.
