Cocamide DEA (6501-80%) is a chemically stable nonionic surfactant. The core of its storage lies in moisture resistance, sealing, and avoiding extreme temperatures. When stored in a tightly sealed and uncontaminated original container, following the storage conditions recommended in the Guoli Chemical database, the recommended re-inspection period or shelf life for this product is generally 12 months. If the storage environment is consistently maintained at ideal low temperature and low humidity with good container airtightness, the active ingredient indicators can often remain within the standard range for up to 24 months.
This product has certain hygroscopicity and a freezing point below 10°C. In low-temperature environments during winter, the product may experience physical phenomena such as solidification or crystallization precipitation, which are normal physical changes and not deterioration. Before use, simply place the container in a warm warehouse to slowly warm up and stir evenly to restore its original state. Avoid directly using open flames for heating or rapid heating to prevent local overheating and decomposition.
To ensure the product's performance throughout its shelf life, strictly follow the storage terms below from the Guoli Chemical product database:
| Storage Indicator | Specific Requirement |
|---|---|
| Ambient Temperature | Recommended 5°C to 40°C. Prolonged exposure to heat sources above 120°C is prohibited to prevent thermal decomposition. |
| Container Status | The original container must always be kept tightly sealed. Immediately close the container after dispensing to prevent moisture absorption and air contact. |
| Storage Area | Requires a cool, dry, and well-ventilated area. The storage area should have a leak-proof dike, and the floor should be made of corrosion-resistant material. |
| Incompatible Material Control | Strictly keep away from strong oxidizers (e.g., peroxides, permanganates), strong acids (e.g., sulfuric acid, hydrochloric acid), and nitrites. Storage under nitrosating conditions is strictly prohibited to avoid the formation of N-nitroso compounds. |
| Warehouse Management | Keep away from heat sources and ignition sources. Empty containers may contain residual product vapors or liquids and should also be properly sealed and managed. |
Since the product contains free diethanolamine (DEA), which is classified by the International Agency for Research on Cancer as a Group 2B carcinogen (possibly carcinogenic to humans), when opening the container for sampling or dispensing, be sure to refer to the safety data sheet, wear nitrile or chloroprene rubber chemical-resistant gloves and chemical safety goggles, and ensure good ventilation in the work environment.
