Dodecylamine polyoxyethylene ether AC-1215 is stable under normal use and storage conditions. However, due to its hygroscopic nature and the presence of amine groups and polyoxyethylene ether chains in its molecular structure, improper storage may lead to product moisture absorption, deterioration, or performance degradation. Therefore, strict adherence to the recommended storage conditions is crucial to ensure product quality and effectiveness.
At low temperatures (below 25°C), the product may appear as a paste or solid, which is a normal physical phenomenon and does not affect product quality. Before use, allow the product to naturally warm up in a warm environment to restore it to a transparent liquid state. Do not use open flames or excessively high temperatures for direct heating, as this may cause product decomposition, producing harmful gases such as carbon monoxide, carbon dioxide, and nitrogen oxides.
Expired products (over 12 months) are not necessarily ineffective, but they must be retested to confirm that all specifications are met before continued use. If the retest fails or the product exhibits abnormal phenomena such as stratification, increased cloudiness, or off-odors, it should be properly disposed of in accordance with hazardous waste management regulations. Do not discharge directly into drains or the environment.
| Storage factor | Specific requirement |
|---|---|
| Ambient temperature | Recommend 5-35°C, cool environment |
| Ambient humidity | Dry, prevent moisture ingress into container |
| Ventilation condition | Well-ventilated warehouse, local exhaust recommended |
| Light requirement | Away from direct sunlight |
| Fire source control | Away from fire and heat sources |
| Container sealing | Keep container tightly sealed to prevent moisture absorption |
| Recommended container material | Stainless steel, polyethylene, lined carbon steel |
| Prohibited container material | Copper, aluminum, and other reactive metal containers |
| Incompatible substances | Strong oxidizers, strong acids (do not store together) |
| Leak protection | Provide containment, such as dikes, for leak collection |
| Shelf life | 12 months (retest required before use after expiry) |
It is recommended to establish product in/out records, noting the production date and storage time of each batch, strictly following the "first-in, first-out" principle to avoid long-term storage and expiration. Regularly inspect containers for integrity, leaks, or seal failure, and address any issues promptly.
For partially used containers after opening, reseal the container as soon as possible to minimize contact with moisture in the air. If on-site dispensing is required, it is recommended to use stainless steel or polyethylene containers for the dispensing and use the product within a short period.
