Octadecylamine polyoxyethylene ether AC-1815 is a white to light yellow waxy solid or paste, with certain hygroscopic properties. Proper storage is crucial for maintaining product performance and effectiveness. The product is usually packaged in cardboard drums or woven bags lined with plastic bags. If the package is opened but not fully used, the inner bag should be resealed to prevent the product from absorbing moisture and caking.
From a chemical stability perspective, AC-1815 should be kept away from ignition sources and strong oxidizing agents. Although the flash point of this product is typically greater than 100°C (closed cup method) and it is not classified as a flammable solid, prolonged exposure to high temperatures should still be avoided. It is recommended to control the storage temperature below 40°C, as high temperatures may cause the product to darken in color or soften, affecting its performance and accuracy in formulation.
When stored under specified conditions and left unopened, the product has a shelf life of up to 12 months. If the product has been opened, it is recommended to use it as soon as possible and to seal it immediately after each use to maximize the effective service life of the remaining product.

If the product exhibits slight moisture absorption and caking due to improper storage, its chemical performance is usually not affected. It can be used after being warmed and softened in a warm environment, or appropriately crushed before use. However, if the product shows significant discoloration, mold, or produces an off-odor, it is not recommended for continued use and should be disposed of in accordance with local regulations.
