Quality Control

Our Sodium β-Hydroxyethoxyacetate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and composition. Certificates of Analysis (COA) documenting results for assay, impurities, and other critical parameters are provided to guarantee traceability and batch-to-batch consistency for your formulations.

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 may lead to caking or degradation.
