As an ethoxylated stearylamine nonionic surfactant, the storage conditions of AC-1820 directly affect its chemical stability and safety in use. During storage, this product should avoid direct sunlight and high-temperature environments to prevent molecular chain degradation or unwanted chemical reactions. The ideal storage temperature range is generally recommended to be controlled between 5°C and 35°C, avoiding extreme low temperatures that may increase product viscosity or even cause solidification, as well as high temperatures that may cause discoloration or oxidative deterioration.
Keeping the container tightly closed is a key part of storage management. AC-1820 molecules contain polyoxyethylene ether segments and have certain hygroscopicity. If the container is not strictly sealed, the product may absorb moisture from the air, leading to changes in the concentration of active ingredients and even microbial growth, affecting the stability and reproducibility of subsequent formulation processes. Additionally, an open state may allow impurities to enter and contaminate the product.
In terms of chemical compatibility, AC-1820 exhibits nonionic characteristics under neutral and alkaline conditions, but in acidic environments, its tertiary amine groups become protonated and convert to cationic behavior. Therefore, during storage, it should be strictly separated from incompatible substances such as strong oxidizers and strong acids to avoid uncontrolled chemical reactions or container corrosion risks. The storage area should be clearly marked and managed under lock, with access limited to trained and authorized personnel.
| Storage Element | Specific Requirement |
|---|---|
| Ambient Temperature | Store in a cool place, avoid high temperatures, recommended 5°C~35°C (Source: General product storage specification) |
| Ambient Humidity | Dry environment to prevent moisture absorption |
| Ventilation Requirement | Well-ventilated dedicated warehouse or area |
| Light Requirement | Avoid direct sunlight |
| Container Condition | Keep tightly closed to prevent moisture ingress or contamination |
| Segregation Requirement | Store separately from incompatible substances such as strong oxidizers and strong acids |
| Safety Management | Warehouse locked, access limited to authorized personnel |
| Stacking Requirement | Stack layers in compliance with safety regulations to prevent container deformation or damage |
In applications such as textile auxiliaries, pesticide emulsifiers, and industrial cleaning agents, it is recommended to check the storage state of the product before compounding. If the product exhibits stratification, turbidity, or abnormal viscosity due to long-term storage or low temperatures, it can be gently stirred at room temperature to restore uniformity before use. Direct heating at high temperatures is strictly prohibited. Unused product after opening should be promptly resealed and prioritized for consumption to avoid long-term exposure affecting batch quality consistency.
