Quality Control

Our Lignin, Alkali, Reaction Products With Disodium Sulfite And Formaldehyde is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters including sulfonate content, pH, reducing sugars, and ash content to ensure consistent performance. Certificates of Analysis (COA) are available upon request to support your quality assurance and regulatory compliance 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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent caking and degradation due to moisture absorption.
