Quality Control

Our Sodium Dihydroxytartrate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and composition. We provide comprehensive Certificates of Analysis (COA) upon request, detailing all relevant parameters. Production can be aligned with various standards, including Food Chemical Codex (FCC) and pharmaceutical-grade requirements, to suit specific customer needs.

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 lead to caking or degradation.
