Quality Control

Our Naphthenic Acid Sodium Salt is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent composition, purity, and performance characteristics. Certificates of Analysis (COA) detailing key parameters such as acid value, saponification value, and moisture content are available upon request to support your quality assurance protocols.

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); ensure the container is kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
