What are the storage conditions for MOA-23 (AEO-23)?

MOA-23 (AEO-23) should be stored in a sealed, cool, dry, and well-ventilated environment. The recommended storage temperature is 5°C to 40°C, away from strong oxidizers, strong acids, and heat sources.

Detailed Description

MOA-23 (AEO-23) is a high-polymerization degree fatty alcohol polyoxyethylene ether nonionic surfactant, appearing as a white waxy solid at room temperature. Due to its special physicochemical properties, proper storage is essential to maintain product quality and performance.

During storage, three points require the most attention: first, seal to prevent moisture, as the polyoxyethylene chain segments in nonionic surfactants have certain hygroscopicity, and exposure to humid air may cause the product to absorb moisture and clump; second, control temperature, the product may soften at high temperatures in summer, but this is a normal physical change and does not affect product quality; third, avoid contact with incompatible substances, especially strong oxidizers and strong acids, to prevent chemical reactions that could degrade the product.

Once opened, it is recommended to use it up as soon as possible or reseal it tightly to minimize exposure to air, thereby extending its effective shelf life.

Application Suggestions

In actual warehouse management, it is recommended to store MOA-23 (AEO-23) on shelves indoors, avoiding direct placement on the floor to prevent moisture. During high summer temperatures, the product may soften or become sticky, which is a normal phenomenon. It can be restored by placing it in a cool place before use, no special treatment is required, and it will not affect emulsification, dispersion, or other application properties.

Precautions

• Product softening in high temperature seasons is a normal physical phenomenon and does not affect quality; do not mistake it for product deterioration.
• Avoid discharging the product directly into water bodies or drainage systems. Its water hazard class is WGK 1 (slightly hazardous to water).
• The storage area should be equipped with spill emergency response materials, such as inert absorbent materials (sand, diatomaceous earth, etc.).
• Operators should wear nitrile rubber gloves and safety goggles when handling, to avoid direct contact with skin and eyes.
