G-25 Glycereth-25, as a polyoxyethylene nonionic surfactant, requires storage precautions focused on preventing moisture absorption, high-temperature degradation, and contamination. The product itself is non-flammable, non-explosive under normal handling conditions, and chemically stable. However, prolonged exposure to high temperatures or humid air may cause moisture absorption, discoloration, or performance degradation.
It is recommended to follow the "First In, First Out" principle for inventory management. Upon receipt, verify that the packaging is intact, labels are clear, and record the batch number and arrival date. Opened packaging should be used as soon as possible; if not used up in one go, promptly reseal the container after each use to minimize air exposure. Use clean, dry tools to avoid introducing moisture and impurities.
| Storage Factor | Specific Requirement |
|---|---|
| Temperature Range | 10°C to 40°C, avoid freezing and prolonged high-temperature exposure |
| Environmental Requirement | Cool, dry, well-ventilated |
| Container Condition | Keep tightly sealed to prevent moisture absorption |
| Avoid Sources | Heat sources, sparks, open flames |
| Incompatible Substances | Avoid storage with strong oxidizers, strong acids, and strong bases |
| Floor Protection | Impermeable surface, with emergency containment trenches or dikes |
| Secondary Containment | Place in a corrosion-resistant, impermeable secondary containment container |
| Regular Inspection | Check packaging for leaks, deformation, or corrosion; transfer immediately if damaged |
Currently, the Guoli Chemical product database does not provide specific shelf life parameters for G-25 Glycereth-25. Based on industry common practice, for glycereth nonionic surfactants that strictly follow the above storage conditions, the typical shelf life for unopened original packaging is 2 years from the date of production.
It is recommended that users refer to the production date and expiration date printed on the product packaging, or request the Certificate of Analysis (COA) for the specific batch from Guoli Chemical to confirm shelf life information. Products beyond their shelf life should not be used directly; they must be retested for key indicators (e.g., appearance, pH value, hydroxyl value, cloud point, etc.) and deemed acceptable before evaluating continued use.
