MOA-7 (AEO-7) is a fatty alcohol polyoxyethylene ether nonionic surfactant with relatively stable chemical properties, but improper storage conditions may still cause product moisture absorption, discoloration, or performance degradation. To ensure product quality, storage specifications must be strictly followed, and the product should be stored in a dedicated warehouse, avoiding co-storage with strong oxidizers, strong acids, strong alkalis, and food ingredients.
Regarding the shelf life, there is no clear shelf life parameter in the product database. According to common industry standards, the shelf life of fatty alcohol polyoxyethylene ether (AEO series) nonionic surfactants under recommended storage conditions (sealed, cool, dry) is usually 2 years (from the date of production). It is recommended that users refer to the batch number and expiration date on the product packaging and follow the first-in-first-out inventory management principle.
After opening, the product should be used as soon as possible. After each use, the container must be immediately resealed to prevent moisture and impurities from entering the air, avoiding product moisture absorption, deterioration, or microbial contamination. If abnormal phenomena such as stratification, turbidity, discoloration, or odor occur during storage, use should be suspended and quality testing should be performed.
| Storage Element | Specific Requirement |
|---|---|
| Ambient Temperature | Cool environment, avoid high temperature and direct sunlight, recommended storage temperature below 40°C |
| Ambient Humidity | Dry environment, prevent product moisture absorption |
| Ventilation Condition | Warehouse should have good ventilation, equipped with local exhaust facilities if necessary |
| Container Status | Always keep sealed, reseal promptly after opening |
| Away from Ignition Sources | Away from heat, sparks, and open flames |
| Isolation Storage | Avoid co-storage with strong oxidizers, strong acids, strong alkalis, and food ingredients |
| Floor Protection | The floor of the storage area should be treated with anti-seepage measures and equipped with leak collection devices |
It is recommended to check the integrity and seal of the product packaging upon receipt to confirm no damage or leakage. MOA-7 may appear as a white paste or solidified state in low-temperature environments; this is a normal physical phenomenon. Before use, the product can be placed in a warm environment to slowly rewarm and stir evenly; product performance is not affected. Avoid directly heating with open flames or high-temperature steam.
