Quality Control

Our Acid Blue 41 is manufactured under a strict quality management system to ensure batch-to-batch consistency and performance. Each lot is tested against stringent in-house specifications for color strength, shade, solubility, and impurity profiles. A Certificate of Analysis (COA) detailing purity, physical properties, and conformance 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 room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect performance.
