Isomeric Alcohol Polyether E-1303 is a nonionic surfactant with excellent chemical stability, which does not easily deteriorate under normal storage conditions. The key points for storage are moisture prevention, sealing, and temperature control. Since the product is hygroscopic, if not sealed promptly after opening, it may absorb moisture from the air, leading to dilution of active ingredients or changes in appearance. Therefore, the container should be resealed immediately after use.
Under recommended conditions (5°C to 40°C, cool and dry, sealed), the product can be stably stored for 2 years. After the shelf life, it is recommended to recheck key indicators such as appearance, pH value, cloud point, and emulsifying performance before use. Only use if the results are satisfactory.
If the product becomes turbid or separates due to low temperature, this is usually a reversible physical change common in nonionic surfactants. Gently warming it to room temperature and stirring evenly can generally restore its usability without affecting performance.
| Storage Element | Specific Requirements |
|---|---|
| Temperature Range | Recommended 5°C to 40°C, avoid freezing or high temperature exposure |
| Environment Requirements | Cool, dry, well-ventilated dedicated warehouse |
| Container Requirements | Keep tightly sealed to prevent leakage and moisture absorption; reseal immediately after opening |
| Isolation Storage | Store separately from strong oxidizers, strong acids, strong bases, and edible chemicals; do not mix |
| Safety Facilities | Equip storage area with spill response equipment and suitable containment materials |
| Packaging Inspection | Regularly check packaging integrity; replace or transfer to intact containers if damaged |
| Shelf Life | Approximately 2 years under recommended storage conditions (database lacks official labeled shelf life data; this is a general reference based on industry experience) |
To ensure optimal product performance, it is recommended to follow the "first in, first out" principle for inventory management. Before each withdrawal, verify that the packaging is intact with no leaks, and seal immediately after use. If the product has been stored for a long time near the minimum temperature (5°C), it can be moved to room temperature in advance to warm up and stirred evenly before use.
