Lauryl Polyoxyethylene Ether LAE-4 should be stored sealed in a dry and ventilated warehouse, with a recommended temperature of 5℃ to 35℃ and a shelf life of two years.

Detailed Description

Lauryl Polyoxyethylene Ether LAE-4 is a non-ionic surfactant with stable chemical properties. It is not flammable or explosive and can be stored and transported according to general chemical regulations. Nevertheless, proper storage is crucial for maintaining its core properties such as emulsification and solubilization. Improper storage may lead to product stratification, moisture absorption, deterioration, or performance degradation.

Under normal storage conditions, this product exhibits excellent chemical stability and is resistant to acids, alkalis, and hard water. However, be aware that if decomposed at high temperatures, it may produce irritating or harmful fumes such as carbon monoxide and carbon dioxide. Therefore, the storage environment must be kept away from ignition sources and heat sources, and prolonged exposure to extreme temperatures should be avoided.

Summary of Storage Conditions

Storage FactorSpecific Requirements
Environmental ConditionsIn a dry, well-ventilated warehouse, away from ignition sources and heat sources
Container StatusKeep the container tightly sealed to prevent moisture absorption and entry of foreign matter
Recommended Temperature5℃ to 35℃
Prohibited ActionsAvoid mixing with incompatible substances such as strong oxidizers, strong acids, and strong bases
Shelf LifeTwo years (under the above storage conditions)
Handling After ExpiryAfter the shelf life, it must be tested and qualified before further use

Application Recommendations

It is recommended that users inspect the appearance of the product before use (it should be a colorless to light yellow transparent liquid). If abnormalities such as stratification, turbidity, or off-odor occur, quality testing should be performed before deciding on use. After opening, any unused product should be sealed promptly to avoid prolonged exposure to air and moisture absorption. For bulk purchasers, it is recommended to follow the first-in, first-out principle and use earlier batches within the shelf life first.

Precautions

  • Avoid prolonged exposure to extreme temperatures (too high or too low) to prevent product stratification or deterioration.
  • Empty containers may contain residual product vapor or droplets. Do not discard or reuse them arbitrarily; dispose of them according to relevant regulations.
  • Do not discharge the product into drainage systems, surface water, or groundwater. In case of major leakage, build dikes to contain and prevent spread.
