Quality Control

Our production of this pigment complex adheres to rigorous quality control protocols to ensure batch-to-batch consistency and performance reliability. Quality is verified through a series of analytical tests including identification, purity assay, and shade strength evaluation. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory compliance needs.

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.
