Detergent AR-812 is a nonionic surfactant mainly composed of fatty alcohol polyoxyethylene ether. It has stable chemical properties and is not prone to decomposition or deterioration under normal temperature conditions. Based on the actual production experience and product characteristics of Guoli Chemical, under standard storage conditions, the recommended shelf life for unopened original products is at least 12 months from the date of manufacture. After the shelf life expires, it is recommended to test appearance, pH value, and detergency performance to confirm quality before use.
This product has slight hygroscopicity, so it is particularly important to keep the container tightly sealed during storage. If left open for a long time, the product may absorb ambient moisture, causing a slight decrease in active ingredient concentration. Additionally, avoiding extreme temperatures is also critical – high temperatures accelerate molecular chain degradation, while low temperatures may significantly increase viscosity or even cause solidification. Although this does not affect chemical effectiveness, it can cause inconvenience in use.
| Storage Parameter | Specific Requirement |
|---|---|
| Storage Environment | Cool, dry, well-ventilated warehouse, away from fire and heat sources |
| Temperature Range | 5 ℃ ~ 40 ℃ (recommended range) |
| Light Requirement | Avoid direct sunlight to prevent product deterioration or container aging |
| Packaging Seal | Keep container tightly sealed; reseal promptly after opening |
| Prohibited Co-storage | Do not store together with strong acids or strong oxidizing agents |
| Emergency Equipment | Storage area should be equipped with spill containment equipment and emergency response supplies |
If the product shows slight stratification or turbidity after storage, it is generally a normal physical phenomenon of nonionic surfactants. Simply stir evenly to restore performance, and the detergency effect will not be affected. However, before use, it is recommended to perform a simple visual inspection and a small-scale detergency test to ensure the product quality meets process requirements. If obvious irreversible stratification, significant darkening of color, or precipitation is found, discontinue use and contact Guoli Chemical technical support.
