Oleth-5, as a nonionic surfactant, requires storage conditions that primarily aim to prevent product deterioration, stratification, or incompatible chemical reactions. This product has a flash point above 150°C (closed cup) and is not inherently flammable, but it can be ignited under high-temperature conditions. Therefore, the storage environment must be kept away from heat sources, sparks, open flames, and other ignition sources.
During storage, the product should be placed on corrosion-resistant trays or spill containment dikes to prevent the spread of any accidental leakage. Containers must be kept tightly closed to avoid prolonged exposure to air, which could lead to moisture absorption or contamination. Additionally, it should be stored separately from food, feed, and drinking water sources to prevent cross-contamination risks.
It is especially important to note that Oleth-5 must be kept away from strong oxidizing agents (such as peroxides, permanganates, concentrated acids, etc.), as incompatible chemical reactions may occur, leading to hazards. Furthermore, avoid exposure to high temperatures, direct sunlight, and freezing environments, as extreme temperatures may cause stratification or performance degradation of the product.
| Storage Parameter | Specific Requirement |
|---|---|
| Storage Temperature | 5–35°C |
| Environmental Requirements | Cool, dry, well-ventilated |
| Container Status | Keep tightly closed |
| Substances to Avoid | Strong oxidizing agents (peroxides, permanganates, concentrated acids, etc.) |
| Conditions to Avoid | Heat sources, sparks, open flames, direct sunlight, freezing |
| Storage Method | Place on corrosion-resistant trays or spill containment dikes |
| Isolation Requirements | Store separately from food, feed, and drinking water sources |
In practical production use, it is recommended to establish a first-in, first-out inventory management system and regularly check container seals and product appearance. If any abnormal phenomena such as stratification, increased turbidity, or significant color deepening are observed, a quality assessment should be conducted before deciding whether to continue using the product. For opened packaging, use it as soon as possible. If short-term storage is needed, be sure to reseal it tightly and place it within the recommended temperature range.
