Quality Control

Our Calcium Pyrophosphate is manufactured under a strict quality management system. Production adheres to relevant standards such as FCC (Food Chemicals Codex) for food-grade material and ISO guidelines for industrial grades. Every batch undergoes rigorous analytical testing to ensure consistent purity, composition, and performance. A Certificate of Analysis (COA) detailing specific batch results is 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). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of atmospheric moisture which may affect flow properties.
