Quality Control

Our Fatty Acids, C16-18, Zinc Salts undergo rigorous quality testing to ensure compliance with industry standards. Production follows strict protocols to guarantee batch-to-batch consistency for performance-critical applications. Certificates of Analysis (COA) detailing key parameters such as zinc content, moisture, and acid value are available upon request.

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); keep the container tightly sealed when not in use to prevent caking and performance degradation due to moisture absorption.
