Emulsifier SG-100 (PEG-100 Stearate) is a non-ionic surfactant, appearing as a white to slightly yellow waxy solid at room temperature. It is chemically stable, but storage conditions have a significant impact on its quality retention and performance. Proper storage management can effectively prevent moisture absorption, discoloration, or performance degradation. It is recommended to strictly adhere to the following storage requirements.
The storage environment should be a dedicated warehouse or area that is cool, dry, and well-ventilated. The product should be protected from direct sunlight and kept away from heat sources, ignition sources, and incompatible substances. Regarding container management, use original sealed containers or compatible storage tanks (e.g., stainless steel, polyethylene, or lined carbon steel containers). After each use, immediately reseal the container to prevent moisture absorption and contamination.
| Storage Condition | Specific Requirement |
|---|---|
| Storage Temperature | 5°C to 40°C, should be maintained above the product's melting point or pour point to ensure good fluidity. Minor temperature fluctuations do not affect product quality. |
| Environmental Requirements | Cool, dry, well-ventilated; avoid direct sunlight; keep away from heat sources and ignition sources |
| Container Material | Stainless steel, polyethylene, or lined carbon steel containers; use original sealed containers |
| Isolation Requirements | Keep away from strong oxidizing agents, strong acids, strong bases, and other incompatible materials |
| Container Sealing | Reseal immediately after use to prevent moisture absorption and foreign matter ingress |
In actual warehouse management, it is recommended to follow the "first in, first out" principle and regularly check container sealing and product appearance. If the product is stored in a low-temperature environment for a long time, causing crystallization or solidification and hardening, the container can be moved to a warm environment for natural warming before use. Minor temperature cycling does not affect product quality and requires no special treatment. Empty containers may have residual product; do not cut, weld, or use them for other materials before cleaning.
