Oleth-5 is a nonionic surfactant with relatively stable chemical properties. However, as a polyoxyethylene ether product, prolonged exposure to high temperatures, light, or humid environments may cause color deepening, pH shift, or reduced emulsifying performance. Therefore, strict storage management is key to ensuring product effectiveness and safety.
According to the chemical safety technical documentation provided by Guoli Chemical, this product should be stored in a cool, dry, well-ventilated warehouse, away from heat sources, sparks, open flames, and other ignition sources. The storage temperature should be controlled within the range of 5–35°C, avoiding high temperature exposure and freezing environments. High temperatures may accelerate oxidative deterioration, while freezing may cause product stratification or cloudiness, affecting performance. Additionally, it must be kept away from strong oxidizing agents (such as peroxides, permanganates, concentrated acids, etc.) to prevent incompatible chemical reactions.
Containers should always be kept tightly sealed to prevent moisture absorption or volatilization, and placed on corrosion-resistant trays or spill containment berms. It is strictly prohibited to store in the same area as food, feed, or drinking water sources to avoid cross-contamination. After opening, unused product should be resealed as soon as possible to minimize air exposure.
| Storage Element | Specific Requirements |
|---|---|
| Temperature Range | 5–35°C, avoid high temperature exposure and freezing |
| Environment Requirements | Cool, dry, well-ventilated |
| Container Status | Keep sealed, reseal promptly after opening |
| Placement Requirements | Place on corrosion-resistant trays or spill containment berms |
| Substances to Avoid | Strong oxidizing agents (peroxides, permanganates, concentrated acids, etc.) |
| Fire Prevention Requirements | Away from heat sources, sparks, open flames, and ignition sources (flash point >150°C closed cup) |
| Segregation Requirements | Avoid storing in the same area as food, feed, and drinking water |
Currently, the Guoli Chemical product database does not provide official standard shelf life data for Oleth-5. According to general industry experience for nonionic surfactants, under strict adherence to the above storage conditions (sealed, protected from light, constant temperature of 5–35°C), unopened products can typically maintain stable performance for 12–24 months. It is recommended that users refer to the batch number and production date on the product packaging and follow a first-in, first-out inventory management principle.
If any of the following abnormal phenomena occur, the product should be discontinued even if it is within the reference shelf life: obvious turbidity or stratification, significant color deepening, off-odor, or pH value significantly deviating from the normal range. It is recommended to sample and test key indicators (such as pH, cloud point, appearance, etc.) upon receipt to establish an internal quality control record.
