Quality Control

Our Aluminium Octadecan-1-Olate is produced under a stringent quality management system. Each batch is tested to ensure it meets precise specifications for identity, purity, and performance characteristics. A comprehensive Certificate of Analysis (COA) detailing assay, heavy metal content, loss on drying, and other critical parameters is provided with every shipment to guarantee consistent quality and traceability for your production 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 to prevent absorption of atmospheric moisture, which can affect product performance.
