OP-10 octylphenol polyoxyethylene ether is a nonionic surfactant with good chemical stability, and it is not prone to decomposition or deterioration under normal storage conditions. However, as a polyoxyethylene ether product, prolonged exposure to high temperature, high humidity, strong light, or long-term contact with air may cause color deepening (oxidation), a small amount of moisture absorption, or slight performance fluctuations. Therefore, following standardized storage methods is key to ensuring product quality and extending service life.
The core principles of storage are "sealed, cool, dry, and ventilated." After opening, the product should be resealed as soon as possible to reduce contact with moisture and oxygen in the air. Although OP-10 has a relatively high flash point (closed cup approximately 250°C) and is not flammable, the storage area should still be kept away from heat sources and ignition sources to maximize safety.
| Storage Element | Specific Requirements |
|---|---|
| Temperature | It is recommended to keep it between 5°C and 40°C, avoiding drastic temperature fluctuations. Low temperatures may cause the product to solidify or precipitate (a physical change that can be restored by slow rewarming), while high temperatures accelerate oxidation. |
| Container Material | Stainless steel, high-density polyethylene (HDPE), or carbon steel lined with epoxy resin are recommended. Avoid prolonged contact with aluminum, copper, and non-polar rubber. |
| Sealing | The container must be kept sealed, opened only during use, and immediately resealed after use to prevent moisture absorption and contamination by impurities. |
| Environmental Requirements | A dedicated warehouse that is cool, dry, and well-ventilated. Set up anti-leakage berms or trays to prevent accidental spills from reaching soil, waterways, or drainage systems. |
| Materials to Avoid | Keep away from strong oxidizers (such as peroxides, hypochlorites), strong acids, strong bases, and other incompatible substances, and store separately. |
| Fire Source Control | Keep away from heat sources, sparks, and open flames. Although it is a non-flammable liquid, the storage area should still enforce a ban on fire sources. |
The official shelf life data for OP-10 is not listed in this product database. Based on industry practices and common experience with similar nonionic surfactants (octylphenol polyoxyethylene ethers), under unopened and strictly following the above storage conditions, the shelf life is typically 12 to 24 months (from the date of production). The specific shelf life should be based on the product outer packaging label, the Certificate of Analysis (COA), or the date indicated by the production batch number.
For products that exceed the labeled shelf life, it is not recommended to directly discard them. Instead, laboratory small-scale testing of key performance indicators (such as appearance, pH value, cloud point, emulsifying power, etc.) can be conducted to evaluate whether they still meet usage requirements. If the test results are within the acceptable range, the product can usually still be used.
