Detergent AR-812 should be stored in a sealed container in a cool, dry, and well-ventilated place (5~40℃). Under proper storage conditions, the shelf life is at least 12 months.

Detailed Description

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 Conditions

Storage ParameterSpecific Requirement
Storage EnvironmentCool, dry, well-ventilated warehouse, away from fire and heat sources
Temperature Range5 ℃ ~ 40 ℃ (recommended range)
Light RequirementAvoid direct sunlight to prevent product deterioration or container aging
Packaging SealKeep container tightly sealed; reseal promptly after opening
Prohibited Co-storageDo not store together with strong acids or strong oxidizing agents
Emergency EquipmentStorage area should be equipped with spill containment equipment and emergency response supplies

Application Suggestions

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.

Precautions

  • Although this product is not classified as a hazardous chemical, it should still be stored out of reach of children and unrelated personnel.
  • During long-term storage, a small amount of water condensation may appear on the barrel wall. This is a normal phenomenon; shake well before use.
  • If the original packaging barrel experiences slight bulging due to climatic reasons, slowly release pressure before opening to prevent liquid splashing.
  • The shelf life data is a recommended value provided by Guoli Chemical based on normal storage conditions. The actual service life may vary slightly depending on specific storage environments.
