Quality Control

Our Tea Tree Oil is produced and tested to meet stringent quality standards, including ISO and GMP guidelines where applicable. We ensure compliance with key pharmacopoeial monographs (such as ISO 4730:2017) which define the required composition of main components like terpinen-4-ol, γ-terpinene, and α-terpinene.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15°C and 25°C (59°F - 77°F). Due to its highly volatile and easily oxidized nature, containers should be kept tightly sealed when not in use and under an inert atmosphere for long-term storage to preserve efficacy and shelf life.
