OP-13 (Octylphenol Polyoxyethylene (13) Ether, CAS No.: 9036-19-5) is a nonionic surfactant. At room temperature, it appears as a colorless to pale yellow oily liquid or paste, with a melting point of approximately 20~25°C, and is hygroscopic. Proper storage is crucial for maintaining the product's active ingredients and performance stability. Since the product is toxic to aquatic organisms (H401), leakage must be strictly prevented during storage to avoid environmental and water pollution.
This product has a flash point above 150°C and is not classified as a flammable liquid. However, it should still be kept away from heat and ignition sources to ensure safety. Due to its hygroscopic nature, if the container is not sealed tightly, it may absorb moisture from the air, leading to a decrease in active content or changes in product properties. Therefore, container closure is the primary condition for storage. Additionally, contact with incompatible substances such as strong oxidizers should be avoided to prevent hazardous reactions.
| Item | Specific Requirement |
|---|---|
| Container Seal | Keep container tightly closed to prevent moisture absorption and external contamination |
| Storage Environment | Cool, dry, and well-ventilated |
| Temperature Control | Control according to the range shown on the product label to prevent freezing or overheating deterioration (melting point approx. 20~25°C) |
| Away from Heat/Ignition Sources | Although flash point >150°C, keep away from open flames and high temperatures |
| Incompatible Substances | Keep away from strong oxidizers |
| Segregation Requirements | Do not store together with food, beverages, or feed |
| Container Material | Use corrosion-resistant, leak-proof materials (recommended: 50 kg/200 kg plastic drums or IBC totes) |
For factories with large daily usage, it is recommended to use IBC totes for centralized storage, with a pump for dispensing to reduce the frequency of opening the lid and minimize moisture absorption risk. Small-quantity users can choose 50 kg or 200 kg plastic drums, and immediately tighten the drum cap after each use. If the storage environment temperature is low, causing the product to become pasty or even solidified, this is a normal physical phenomenon. Before use, place the drum in a warm environment to slowly return to a temperature above 20~25°C to restore fluidity. Do not directly use open flames or high-temperature steam for heating.
