Question

What are the storage conditions for XPO-5 styrenated phenol polyoxyethylene ether ammonium sulfate?

XPO-5 should be stored in a cool (5–40°C), dry, well-ventilated dedicated warehouse, with the container kept sealed, away from heat sources, open flames, and incompatible substances.

Detailed Description

XPO-5 styrenated phenol polyoxyethylene ether ammonium sulfate is stable under recommended conditions and is a non-flammable, non-explosive product. To ensure product quality and usage safety, strict control of environmental conditions is required during storage. The product should be stored in a cool, dry, well-ventilated dedicated warehouse, with a recommended storage temperature maintained between 5–40°C, avoiding extreme temperatures that may affect the viscosity and performance of the product.

During storage, the container must be kept completely sealed to prevent moisture absorption and contamination from impurities. After opening, the container should be resealed immediately and stored upright to avoid leakage. The warehouse should be kept away from heat sources and open flames. Although the product itself is not flammable or explosive, it may decompose under high temperature or combustion conditions, producing harmful gases such as carbon monoxide, carbon dioxide, sulfur oxides (SOₓ), and ammonia.

Additionally, XPO-5 should be stored separately from incompatible substances such as strong oxidizing agents, strong acids, and strong bases, and must not be mixed during storage. The storage area must be kept away from food, beverages, and animal feed, and equipped with emergency spill response equipment and suitable containment materials (such as inert absorbents) to handle unexpected situations.

Application Recommendations

XPO-5, as an anionic surfactant, is widely used in pesticide emulsifiers, emulsion polymerization emulsifiers, textile auxiliaries, and industrial detergents. It is recommended to check the storage status before use, ensuring the product appears as a light yellow to brownish-yellow transparent viscous liquid without layering or abnormal precipitation before feeding. For long-term stored products, it is recommended to follow the "first-in, first-out" principle and regularly check container sealing.

Precautions

  • Avoid moisture absorption; high humidity environments may affect product quality stability.
  • Never contact with strong oxidizing agents to prevent violent reactions.
  • The storage area should display clear chemical safety signs and restrict access to unauthorized personnel.
  • Although the product has low toxicity and is easily biodegradable, prevent leakage into sewers, waterways, or groundwater.
  • Regularly check container integrity; if damage or leakage is found, immediately transfer to an intact container.
