PEG-6 Stearate must be stored in a cool, dry, well-ventilated warehouse in a sealed container, with temperature controlled between 15°C and 35°C, away from fire sources and incompatible substances.

Detailed Description

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.

Precautions

  • This product is non-flammable (flash point > 150°C), but it is still recommended to implement general protective measures against dust explosion to prevent dust accumulation.
  • Seal the container immediately after each use to minimize contact with air and prevent moisture absorption and deterioration.
  • If a spill occurs, absorb it with sand, vermiculite, or other inert materials, collect it, and avoid entry into sewers or soil; dispose of waste according to local regulations.
  • The product is stable under recommended storage conditions; if used after long-term storage, it is recommended to conduct a small-scale retest to confirm performance indicators.
