L-62 Poloxamer (Poloxamer 182) is a chemically stable nonionic block copolymer surfactant with excellent chemical resistance. Proper storage is key to ensuring long-term performance of the product. Under original sealed packaging conditions, the product can maintain performance stability within its shelf life and is not prone to deterioration or stratification.
The core principles of storage are moisture-proof, sealed, and away from incompatible substances. Since the product is slightly hygroscopic, exposure to moisture and humid air may cause changes in performance, making sealed storage particularly important. Meanwhile, at room temperature, the product is a colorless to slightly yellow transparent oily liquid with a flash point above 200°C. It is not classified as a flammable dangerous good, but it should still be kept away from heat sources and open flames to ensure safety.
| Storage Element | Specific Requirement |
|---|---|
| Temperature | Cool environment, recommended temperature range 5~30°C |
| Environment | Dry, well-ventilated warehouse area |
| Container Status | Keep sealed to prevent moisture and water vapor ingress |
| Container Material | Stainless steel, glass, polyethylene (PE) and other compatible material sealed containers are recommended; original containers should be used preferentially |
| Substances to Avoid | Strong oxidizing agents, strong acids, strong bases, and other incompatible substances |
| Conditions to Avoid | Heat sources, sparks, open flames |
| Supporting Facilities | Storage area should be equipped with appropriate spill containment facilities |
The product database currently does not provide a specific shelf life value. Generally, similar polyether-type nonionic surfactants, when strictly following the above storage conditions (original sealed, cool and dry, 5~30°C), typically have a shelf life of 12 to 24 months. For specific batch products, please refer to the date indicated on the product packaging label or Certificate of Analysis (COA).
