Question

What are the storage conditions for XPO-4 (Glycerol polyoxyethylene ether oleate), a high-temperature leveling agent?

XPO-4 should be stored sealed in a cool, dry, well-ventilated warehouse at 5°C to 40°C, away from strong oxidizers, strong acids and bases, as well as food and feed.

Detailed Description

XPO-4 (Glycerol polyoxyethylene ether oleate) is a nonionic surfactant, appearing as a light yellow to yellow transparent viscous liquid at room temperature, with a flash point above 150°C. It is a non-flammable liquid with relatively good storage safety. However, as a chemical auxiliary, it still requires standard storage practices to ensure product quality stability and usage safety.

The storage environment should be cool, dry, and well-ventilated, avoiding prolonged exposure to high temperature or humidity. Although the product has a high flash point and is not flammable, high temperatures may accelerate oxidation or cause viscosity changes, affecting performance. Meanwhile, the container must be kept sealed to prevent moisture or impurities from entering.

Special attention should be paid to keeping XPO-4 separate from incompatible substances such as strong oxidizers, strong acids, and strong bases to avoid chemical reactions that could degrade the product. In addition, because the product is harmful to aquatic life (Aquatic Acute Category 3), the storage area should be equipped with a dike or leak containment system to prevent accidental spills from entering drainage systems or water bodies.

Application Recommendations

In daily use, it is recommended to store XPO-4 in its original sealed container, tightly closing the lid after each use. If the product becomes more viscous or turbid due to low temperature, allow it to naturally return to room temperature before use; do not directly heat it. For long-term storage, follow the "first in, first out" principle and regularly inspect container seals and product appearance.

Precautions

  • Away from food and feed: The storage area must be strictly separated from food, beverages, and animal feed to prevent cross-contamination.
  • Avoid freezing: Storage temperature should not fall below 5°C; freezing may cause structural damage or separation.
  • Spill response: In case of a spill, use inert absorbent materials (e.g., sand, vermiculite) to contain and collect; do not wash directly into drains or surface waters.
  • Personal protection: Wear protective goggles and chemical-resistant gloves when handling; no eating, drinking, or smoking in the storage area.
