Quality Control

Our (2-Hydroxypropyl)Methyldioctadecylammonium Chloride is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise specifications and is suitable for its intended industrial applications. A comprehensive Certificate of Analysis (COA) is provided with each shipment to guarantee traceability and compliance.

Storage

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