Quality Control

Our Acid Orange 130 is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including identification, purity assay, and strength evaluation, to ensure it meets precise colorant specifications. A Certificate of Analysis (COA) documenting these results is provided with each shipment to guarantee consistency and performance for your applications.

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, which can affect product performance.
