Quality Control

Our Light Green Sf Yellowish is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity. Each lot is tested against rigorous in-house specifications, which typically include parameters for color strength, shade, solubility, and impurity profiles. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee compliance with your application requirements.

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.
