Quality Control

Our Triisostearyl Citrate is manufactured under strict quality management systems to ensure batch-to-batch consistency and purity suitable for cosmetic and personal care applications. Quality is verified through comprehensive analytical testing including assay, identity confirmation, and impurity profiling. A Certificate of Analysis (COA) documenting purity, physical characteristics, and compliance with relevant specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen) to preserve quality and prevent degradation. Keep away from strong oxidizing agents.
