Quality Control

Our Tris(Octadecanoate-.Kappa.O)Tri-.Mu.-Oxotri-Aluminum is manufactured under strict quality management systems. Each batch is analyzed to ensure consistent composition, purity, and performance characteristics relevant to its industrial applications. Certificates of Analysis (COA) detailing key parameters such as aluminum content, stearate content, moisture, and residual solvents are available upon request. We can support compliance with standards relevant to your specific industry, including food contact or pharmaceutical excipient guidelines where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from strong oxidizing agents.
