Shelf Life & Storage
| Item | Detail |
|---|---|
| Shelf life (unopened) | 2 years from production date |
| After opening | Use within 6-12 months with tight re-sealing |
| Storage conditions | Sealed original container, dark, dry, 5-25 °C |
| Signs of degradation | Harsh/cooked odor, oxidation notes, increased peroxide value |
- The terpinen-4-ol content stays within ISO 4730 spec throughout the shelf life when stored correctly
- Oxidation is the main aging risk — minimize headspace air and light exposure
- Larger drums can be topped up with nitrogen after partial use, or transferred to smaller containers
- Retain a sealed sample from each delivery for reference comparison
- If the oil is stored beyond the stated shelf life, re-test peroxide value and GC profile before use — often it remains usable with confirmed spec
