Quality Control

Our Acid Blue 127 is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise specifications for color strength, shade, solubility, and impurity profiles. Certificates of Analysis (COA) documenting purity, physical properties, and performance characteristics are available upon request to support your quality assurance protocols.

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 absorption of atmospheric moisture, which can affect product performance.
