Quality Control

Our p-Menthane-3,8-Diol is produced under strict quality management systems. We offer grades suitable for cosmetic, food, and pharmaceutical applications, with quality assurance protocols aligned with relevant industry standards. Comprehensive testing ensures consistent purity, sensory profile, and safety. A Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each batch.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage or opened containers, an inert atmosphere (nitrogen blanket) is recommended to maintain optimal stability and prevent degradation.
