OP-30 Octylphenol Ethoxylate (CAS No.: 9036-19-5) appears as a white to light yellow waxy solid or paste at room temperature. Proper storage conditions are crucial for maintaining the product's chemical stability and performance. This product is a non-ionic surfactant with relatively stable chemical properties, but unsuitable storage environments may still cause moisture absorption, discoloration, stratification, or reduced efficacy.
Special attention should be paid to temperature control during storage. The product technical specification recommends keeping the storage temperature within a specified range, avoiding both high temperatures (which may accelerate oxidation, cause darkening, or degrade the product) and freezing (which may disrupt product uniformity and even cause container rupture). Additionally, this product is hygroscopic; ensure the container is always tightly sealed, and reseal immediately after opening to prevent moisture absorption and caking.
| Storage Element | Specific Requirements |
|---|---|
| Environment | Cool, dry, well-ventilated dedicated warehouse |
| Temperature Control | Avoid high temperatures or freezing; keep within the range recommended by the product technical specification |
| Light Requirements | Away from direct sunlight |
| Fire/Heat Sources | Away from fire and heat sources |
| Container Sealing | Keep container tightly sealed; reseal immediately after opening |
| Isolation Storage | Store strictly separately from food, beverages, feed, and strong oxidizers |
| Spill Containment | Equip with spill containment trays or dikes; use impermeable flooring materials |
In practical warehouse management, it is recommended to store OP-30 indoors at a temperature of 10–30°C with a relative humidity not exceeding 60%. It can be packaged in original sealed drums or fiber drums lined with plastic bags. If the product solidifies or separates due to low temperature, slowly warm it in a warm environment and stir evenly before use; do not directly heat with open flames or steam.
Follow the first-in, first-out (FIFO) principle, prioritizing earlier batches within the shelf life. Regularly check the integrity and sealing of packaging; if leakage or damage is found, immediately transfer to an intact container.
