Quality Control

Our Sodium L-Aspartate is manufactured under a strict quality management system. We offer grades compliant with Food Chemical Codex (FCC) and pharmaceutical standards, ensuring suitability for sensitive applications. Every batch is supported by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and safety parameters, available upon request to guarantee traceability and regulatory compliance.

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 flow properties.
