Quality Control

Our 2-Hydroxyethyldimethyl-3-Stearamidopropylammonium Phosphate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, performance, and compliance with relevant specifications for personal care and industrial use. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment.

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/59-77°F). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product quality.
