Quality Control

Our Zinc Disodium EDTA Dihydrate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for pharmaceutical and food-grade applications. Certificates of Analysis (COA) documenting key parameters such as assay, heavy metals, and loss on drying are provided with every shipment. We adhere to relevant guidelines and can supply material compliant with in-house specifications aligned with USP/NF or FCC monographs upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed after use to prevent absorption of atmospheric moisture, which can lead to caking and reduced stability.
