Quality Control

Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Key parameters such as color strength, metal content, and impurity profiles are strictly monitored. Certificates of Analysis (COA) documenting these specifications 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 to prevent absorption of atmospheric moisture.
