Dodecyl Polyoxyethylene Ether AC-1210 should be stored sealed in a cool, dry, and well-ventilated place at 5~40°C, with a shelf life of two years under recommended conditions.

Detailed Explanation

Dodecyl Polyoxyethylene Ether AC-1210 (CAS No.: 26635-75-6) is a nonionic surfactant that is chemically stable under normal temperature and pressure. This product is hygroscopic, so the container must be kept tightly sealed during storage. It is recommended to store it in the original container to avoid moisture absorption from the air that could lead to deterioration. The product has a flash point greater than 150°C and is not classified as dangerous goods, but it should still be kept away from heat sources and high temperatures.

The storage environment should avoid direct sunlight, as ultraviolet radiation may trigger slow oxidative degradation, affecting the color and performance of the product. Additionally, the product exhibits weak cationic properties and should be kept away from strong oxidizers, strong acids, and strong bases and other incompatible substances to prevent chemical reactions that could cause product failure or safety hazards.

Under recommended storage conditions (temperature 5~40°C, original sealed container, cool, dry, and well-ventilated), the shelf life of the product can reach two years. It is recommended to manage inventory using the "first-in, first-out" principle. Products exceeding the shelf life should undergo performance testing before further use, and only those passing the test should be used.

Application Recommendations

After opening the drum, reseal the container as quickly as possible to minimize the product's exposure to air. If the product becomes turbid or stratified at low temperatures, this is a normal physical change. Move the container to a warm environment to slowly return to room temperature and stir evenly before use; product performance will not be affected. Special attention should be paid to frost protection in winter to prevent the product from solidifying at temperatures below 0°C, which could cause difficulties in dispensing.

Precautions

  • The storage area should be designated as a restricted access area, with appropriate warning signs posted (signal word: Warning).
  • The product is chronically toxic to aquatic life (H412). Do not discharge spills directly into sewers or water bodies; rinse water must be collected and treated in accordance with local environmental regulations.
  • Long-term storage at high temperatures may cause darkening of the product color. It is recommended to periodically inspect the appearance of stored inventory.
