Quality Control

Our Alkali Lignin is produced under strict quality management protocols to ensure batch-to-batch consistency and performance reliability. While specifications vary by grade and application, our standard quality commitment includes comprehensive testing for parameters such as solids content, pH, sulfonate content, and ash. A Certificate of Analysis (COA) detailing the specific results for your order is provided with every shipment.

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); ensure containers are kept sealed when not in use to prevent caking and degradation due to moisture absorption.
