Quality Control

Our Reactive Red 116 is produced under a strict quality management system to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analysis, including strength (tinctorial value), shade, solubility, and fixation properties. A Certificate of Analysis (COA) detailing purity, physical parameters, and application test results is provided with every shipment 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). Keep away from strong oxidizing agents. The product is hygroscopic (moisture-sensitive); ensure the original container is sealed after each use to prevent moisture absorption and caking.
