Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is controlled for identity, purity, and consistency to meet the specific requirements of dye and pigment manufacturing. Certificates of Analysis (COA) documenting key parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture.
