As an accredited Methylisothiazolinone factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | A white plastic drum labeled "Methylisothiazolinone, 99%, 25 kg." The label includes hazard symbols, batch number, and manufacturer details. |
| Container Loading (20′ FCL) | 20′ FCL container typically loads 16–18 metric tons of Methylisothiazolinone, securely packaged in drums or IBCs for safe transportation. |
| Shipping | Methylisothiazolinone should be shipped in tightly sealed containers, protected from light and moisture. It must be clearly labeled and transported according to local, national, and international regulations for hazardous chemicals. Avoid extreme temperatures, direct sunlight, and incompatible substances to ensure stability and safety during transit. Handle with appropriate personal protective equipment. |
| Storage | Methylisothiazolinone should be stored in a cool, dry, and well-ventilated area away from direct sunlight, heat sources, and incompatible materials such as strong oxidizers. Containers must be tightly closed and clearly labeled to prevent contamination and leaks. Store at temperatures between 4–25°C. Properly secure storage areas and ensure access is limited to trained personnel to promote safety. |
| Shelf Life | Methylisothiazolinone typically has a shelf life of about 12–24 months when stored tightly sealed in a cool, dry place. |
