PEG200MO is a non-ionic surfactant with stable chemical properties and is not classified as a hazardous chemical. However, under improper storage conditions, the product may undergo phase separation, moisture absorption, degradation, or performance changes. To ensure at least 12 months of stability from the date of production, it is recommended to strictly follow the storage specifications below and implement a first-in, first-out inventory management principle.
This product has certain hygroscopic properties. Long-term exposure to high-humidity environments will cause it to absorb moisture from the air, potentially leading to a decline in product performance. In addition, although the product has an open-cup flash point greater than 200°C and is not classified as a flammable liquid, it is still recommended to keep it away from open flames and heat sources to maximize storage safety.
| Storage Condition | Specific Requirement |
|---|---|
| Ambient Temperature | Recommended 5°C to 35°C, avoid extreme high temperatures or freezing conditions |
| Ambient Humidity | Dry environment, avoid high humidity (product is hygroscopic) |
| Ventilation Requirement | Warehouse should be well-ventilated |
| Container Status | Keep tightly closed; reseal promptly after opening |
| Recommended Container Material | Stainless steel, high-density polyethylene (HDPE), or epoxy-lined containers |
| Heat Source Management | Keep away from open flames, hot surfaces, and other ignition sources |
| Incompatible Substances | Avoid storage with strong oxidizers, strong acids, and strong bases |
| Storage Period | At least 12 months from the date of production under recommended conditions |
In actual use, it is recommended to adopt a first-in, first-out inventory turnover principle and regularly inspect the appearance of the product in stock (normal appearance is a light yellow to yellow viscous liquid). If the product experiences layering or turbidity due to low-temperature environments, it can be slowly warmed to room temperature before use with moderate stirring; this usually restores uniformity without affecting product performance.
