Quality Control

Our production of Dipotassium 2,5-Dimethyl-3,6,9,12,15,18,21,24-Octaoxahexatriacontan-1-Yl Dihydrogen Phosphate adheres to stringent quality management systems. Every batch undergoes rigorous analytical testing, including assay, impurity profiling, and physical characterization, to ensure it meets precise customer specifications and industry benchmarks for high-purity surfactants. Certificates of Analysis (COA) documenting purity, identity, and key parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and performance.
