OP-10 octylphenol polyoxyethylene ether is a nonionic surfactant with good chemical stability, but under improper storage conditions, it may still undergo moisture absorption, oxidation, or degradation, affecting product performance. To ensure product quality and usage safety, the following storage specifications should be strictly followed.
Although this product is not flammable (flash point >200°C, typically about 250°C), a fire prohibition zone should still be enforced in the storage area, away from heat sources, sparks, open flames, and other ignition sources. At the same time, drastic temperature fluctuations should be avoided. The ambient temperature is recommended to be maintained between 5°C and 40°C. Excessive temperatures may accelerate product oxidation and discoloration, while too low temperatures may cause the paste to solidify, affecting ease of use.
Container and material selection are equally critical. It is recommended to use stainless steel, polyethylene (HDPE), or carbon steel containers lined with epoxy resin. Prolonged contact with aluminum, copper, and non-polar rubber should be avoided to prevent container corrosion or material swelling. After each use, the container should be immediately resealed to prevent product moisture absorption and impurity contamination. Additionally, spill containment dikes or trays should be set up to control accidental spills, and leakage into soil, waterways, or drainage systems is strictly prohibited.
| Storage Parameter | Requirement |
|---|---|
| Storage Temperature | 5°C–40°C (recommended) |
| Environmental Requirement | Cool, dry, well-ventilated |
| Container Material | Stainless steel, HDPE, carbon steel lined with epoxy resin |
| Materials to Avoid | Aluminum, copper, non-polar rubber |
| Flash Point (Closed Cup) | ＞200°C (typically about 250°C) |
| Auto-Ignition Temperature | ＞350°C |
| Incompatible Substances | Strong oxidizers (peroxides, hypochlorites), strong acids, strong bases |
In industrial applications, it is recommended to store OP-10 in a dedicated warehouse, equipped with local exhaust ventilation and temperature/humidity monitoring devices. For bulk storage, use storage tanks or large-capacity HDPE drums in conjunction with spill containment trays. For long-term inventory, follow the "first-in, first-out" principle, regularly check container seals and product appearance (color, transparency, whether there is stratification or precipitation) to ensure the product maintains optimal performance within its effective shelf life.
