Isomeric Tridecanol Polyoxyethylene Ether E-1306 is a nonionic surfactant that is relatively stable under recommended conditions. Proper storage is crucial for maintaining its emulsifying ability, wetting and penetrating properties, and dispersibility. Improper storage may lead to moisture absorption, color deepening, or reduced surface activity, thereby affecting its application effects in industrial cleaning, textile printing and dyeing, metal processing, and other fields.
Regarding the shelf life, the Guoli Chemical product database currently does not provide a specific shelf life value for this product. Generally, for nonionic surfactant products under sealed, cool, and dry recommended storage conditions, the shelf life from the date of manufacture is usually 12 to 24 months. It is recommended to refer to the specific validity period marked on the factory inspection report or certificate attached to the product packaging, and follow the first-in, first-out inventory management principle.
Products beyond the shelf life are not recommended for direct use. Performance retesting (such as checking emulsifying power, penetrating power, pH value, and other key indicators) should be conducted. Only if qualified, they can be used for downgraded applications or reevaluated for suitability.
| Storage Element | Specific Requirement |
|---|---|
| Environmental Conditions | Cool, dry, and well-ventilated warehouse, avoid direct sunlight and rain |
| Temperature Range | Recommended to be maintained between 5°C and 40°C, away from extreme high temperatures and strong heat sources |
| Container Requirements | Keep container tightly closed, recommended to use stainless steel, polyethylene (PE), or polypropylene (PP) packaging |
| Isolation Requirements | Keep away from strong oxidizers, strong acids, strong alkalis, and other incompatible substances |
| Warehouse Management | Set up clear safety signs, equip with fire-fighting equipment and leakage emergency handling devices, follow the first-in, first-out principle |
Due to the unique branched chain structure of isomeric alcohol, this product has good low-temperature fluidity and a low pour point, making it less prone to solidification in cold environments compared to linear alcohol polyether products. However, to ensure optimal performance, anti-freezing measures should still be considered during winter storage. If turbidity or stratification occurs due to low temperatures, slowly warm the product to 15°C~30°C before use and stir evenly; this usually does not affect product performance.
