Quality Control

Our Phosphoric Acid, C12-18-Alkyl Esters is produced under a strict quality management system. Each batch is tested to ensure consistent composition, acidity, and performance characteristics. Certificates of Analysis (COA) detailing key parameters such as acid value, mono-ester content, and alkyl chain distribution are provided with every shipment to guarantee product integrity and traceability.

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 containers are sealed immediately after use to prevent absorption of atmospheric moisture, which can affect product quality.
