Quality Control

Our p-Mentha-8-Thiol-3-One is produced and tested under a strict quality management system. Each batch is analyzed to ensure it meets stringent specifications for identity, purity, and organoleptic quality, aligning with industry standards such as FEMA GRAS and IFRA guidelines. Comprehensive Certificates of Analysis (COA) detailing assay, impurity profile, and physical constants are available upon request to support your compliance and formulation needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) in a cool, dry, and well-ventilated area at 2-8°C (refrigerated) or as specified on the label. Due to its highly volatile and easily oxidized nature, minimize headspace and avoid prolonged exposure to air, heat, or moisture.
