OP-30 (Octylphenol polyoxyethylene ether) is a nonionic surfactant, appearing as a white to light yellow waxy solid or paste. The key to storage is to prevent moisture absorption, heat degradation, and contact with incompatible substances. Proper storage not only ensures product performance stability but also effectively mitigates safety risks.
Regarding shelf life, there are currently no official shelf life parameters for this product in the data repository of Guoli Chemical. Based on industry practice and the chemical stability of this type of nonionic surfactant, under strict compliance with the following storage conditions, OP-30 can typically be stably stored for 1 to 2 years. It is recommended to follow the "First-In, First-Out" principle and check for any changes in product appearance and performance before use. If the product exhibits noticeable color deepening, stratification, unusual odor, or other anomalies, discontinue use. The shelf life for specific batches shall be based on the product packaging label or factory inspection report.
| Storage Element | Specific Requirement |
|---|---|
| Environmental Conditions | Store in a cool, dry, well-ventilated dedicated warehouse, away from fire, heat sources, and direct sunlight. Avoid high temperatures to prevent product softening or deterioration; avoid freezing to prevent structural damage. |
| Container Sealing | Keep containers tightly closed. Reseal opened containers immediately after use to prevent moisture absorption and foreign matter entry. |
| Temperature Recommendation | It is recommended to store at temperatures within the range specified in the product technical data sheet. OP-30 is a waxy solid/paste; storage at room temperature (15-30°C) is sufficient, avoiding extreme high or low temperatures. |
| Segregation | Store strictly separately from food, beverages, feed, and strong oxidizing agents to prevent cross-contamination or unsafe reactions. |
| Spill Prevention | The storage area should be equipped with spill containment trays or dikes, and the floor surface should be made of impermeable material to contain any potential leaks. |
When taking OP-30, it is recommended to use clean, dry tools to avoid introducing moisture or other impurities into the packaging container. As this product may become viscous or paste-like at low temperatures, if difficult to use in winter, the sealed package can be placed in a warm environment for slow temperature recovery (recommended not to exceed 40°C) before use. Direct heating with open flame or steam is strictly prohibited to avoid localized overheating leading to product degradation.
