Quality Control

Our production of this complex colorant adheres to strict batch-to-batch consistency protocols to ensure reliable performance in your formulations. Quality is verified through a comprehensive suite of analytical tests, including spectrophotometric analysis for color strength and purity, and assessments for heavy metal content and other impurities. A Certificate of Analysis (COA) detailing specific batch results is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect performance.
