Quality Control

Our Acid Brown 100 is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters including color strength, shade, solubility, and impurity profile to ensure batch-to-batch consistency and compliance with industry standards. A Certificate of Analysis (COA) detailing these specifications is available upon request.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed when not in use to prevent moisture absorption, which can affect performance.
