Quality Control

Our octasodium dye complex is produced under a stringent quality management system. Every batch undergoes comprehensive analytical testing to ensure consistency in color value, strength, purity, and impurity profile. We provide Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, solubility, and heavy metal content. Our quality commitment aligns with industry standards for dye manufacturing, ensuring reliable performance in your formulations.

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). Keep away from incompatible materials such as strong oxidizing agents. Due to its light-sensitive nature, prolonged exposure to direct light should be avoided to maintain product integrity.
