PEG-6 Stearate is a non-ionic surfactant, appearing as a white to slightly yellowish waxy solid or flakes at room temperature. Correct storage conditions are crucial for maintaining its chemical stability and performance. Although this product is non-flammable (flash point > 150°C, closed cup method), care must be taken to prevent extreme temperatures that may cause changes in material properties.
The main risks during storage are moisture absorption and contamination. Due to the presence of polyoxyethylene chains in its molecular structure, it has certain hygroscopicity; exposure to humid air may lead to caking or performance degradation. At the same time, as a surfactant, storage with incompatible chemicals may cause cross-contamination, affecting the stability and effectiveness of subsequent formulations.
In addition, leakage emergency treatment equipment and suitable containment materials (such as inert absorbents, empty containers) should be provided in the handling and storage area for emergencies. Eating, smoking, or drinking is strictly prohibited in the storage area to ensure personnel safety and material purity.
