Quality Control

Our Carboxymethyl-β-1,3-Glucan is produced under a strict quality management system. Each batch is tested to ensure it meets precise specifications for degree of substitution, viscosity, and purity. Certificates of Analysis (COA) documenting key parameters are available upon request, supporting compliance for use in cGMP and ISO-regulated environments.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product performance.
