Under proper storage conditions, the shelf life of OP-4SA nonylphenol polyoxyethylene ether ammonium sulfate is 12 months. The product should be packaged in clean, sealed plastic drums or iron drums lined with plastic bags. The storage area should be equipped with leak collection devices, the floor should be impermeable, and corresponding fire-fighting and emergency equipment should be provided. It is recommended to use anti-corrosion and leak-proof storage containers and pallets, preferably made of stainless steel, polyethylene, or lined polypropylene materials.
The product should be stored separately from strong oxidizing agents, strong acids, and alkalis to avoid hazardous reactions. When not in use, the container must be tightly closed to avoid prolonged exposure to air and moisture, preventing moisture absorption and deterioration. Regularly check the integrity of the packaging and comply with shelf life management.
If turbidity or stratification occurs under low temperature conditions, it is a normal physical phenomenon and not a product quality issue. Simply warm the product to room temperature and stir thoroughly to restore normal use without affecting product performance. At the same time, avoid excessive temperature that may cause an increase in internal pressure of the container.
