Stearic acid polyoxyethylene ether SG-10 (PEG-10 stearate) is a nonionic surfactant, appearing as a light yellow paste to solid at room temperature. Due to the presence of polyoxyethylene chains in its molecular structure, the product has certain hygroscopicity, so moisture-proof must be particularly attended during storage to avoid moisture absorption causing caking or deterioration.
The product is chemically stable but may degrade when exposed to high temperatures or strong oxidizers. Therefore, it is recommended to control storage temperature below 40°C and store separately from acids and strong oxidizers to avoid incompatible reactions. The warehouse floor should be impermeable and equipped with spill containment facilities to deal with accidental leaks.
In practice, containers should be sealed promptly after each use to prevent moisture absorption and cross-contamination from prolonged exposure to air. Adhering to these storage conditions can effectively ensure product quality stability, and the shelf life is relatively long under normal storage conditions.
| Storage Factor | Specific Requirement |
|---|---|
| Ambient Temperature | Recommended not to exceed 40°C, avoid high temperature causing softening or deterioration |
| Ambient Humidity | Dry and ventilated, prevent moisture absorption and caking |
| Container Status | Keep tightly closed, seal promptly after use |
| Storage Location | Cool, well-ventilated dedicated warehouse, away from heat sources, sparks and open flames |
| Isolation Requirement | Store separately from strong oxidizers and acids |
| Floor Requirement | Possess impermeable properties, with spill containment facilities |
It is recommended to establish a first-in-first-out inventory management system and regularly check container sealing and product appearance. If abnormal discoloration, odor or severe caking is found, use should be discontinued and a quality re-inspection conducted. The warehouse should be equipped with firefighting equipment (such as water mist, dry powder, carbon dioxide extinguishers) and keep fire passages unobstructed.
