Quality Control

Our Calcium Phenolsulfonate is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and composition. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, moisture content, and heavy metal limits to guarantee batch-to-batch consistency and reliability for your processes.

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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect quality and handling properties.
