Polyethylene glycol 400 dioleate (PEG400DO), as a nonionic surfactant, is relatively chemically stable. However, proper storage conditions are crucial to maintaining product performance and shelf life. This product appears as a light yellow to amber liquid at room temperature. During storage, ensure the container is tightly sealed to prevent moisture ingress and contamination by impurities.
It is recommended to maintain the storage temperature between 5°C and 40°C, avoiding prolonged exposure to high temperatures (above 50°C) or low-temperature freezing conditions. Low temperatures may cause increased viscosity, turbidity, or solidification. If this occurs, slowly warm the product to room temperature and stir evenly before use; this generally does not affect product performance. Keep away from fire, heat sources, and strong oxidizers. The storage area should be well-ventilated.
This product is biodegradable, but care should be taken to avoid direct discharge into water bodies. Waste disposal should comply with local environmental regulations. Under recommended storage conditions, the shelf life of unopened original packaging is typically 12–24 months. Please refer to the product packaging label for specific details.
| Item | Recommended Condition |
|---|---|
| Storage Temperature | 5°C ~ 40°C (room temperature storage) |
| Environmental Requirements | Cool, dry, well-ventilated |
| Container Status | Sealed to avoid moisture absorption and contamination by impurities |
| Substances to Avoid | Fire sources, high heat, strong oxidizers |
| Packaging Material | It is recommended to use stainless steel, polyethylene (PE), or lined coated iron drums |
After removing product, promptly seal the container to minimize prolonged exposure to air, thereby preventing moisture absorption or oxidation. For products intended for use after long-term storage, it is recommended to perform a visual inspection and simple performance test before feeding to confirm no abnormalities. If stratification, precipitation, or significant color darkening occurs, conduct a quality assessment before deciding whether to use.
Note: The above general storage recommendations are based on the chemical properties of the product. For specific storage conditions and shelf life, please refer to the product packaging label and quality inspection report provided by Guoli Chemical.
