How should I store this green mandarin oil and what is its shelf life?
Green mandarin oil is a monoterpene-rich citrus oil that oxidises faster than most essential oils. Stored correctly — full, closed, cool, and dark — it keeps its fresh character for up to 18-24 months from filling.
Storage and Shelf Life
| Item | Recommendation |
|---|---|
| Shelf life | 18-24 months from filling date when stored correctly |
| Container | Original sealed drum, HDPE jerrican, or dark glass; keep headspace minimal |
| Temperature | 5-20°C, away from heat sources and direct sunlight |
| Humidity | Dry warehouse — avoid damp storage rooms |
| Closure | Always re-seal immediately; oxygen is the main enemy |
| Oxidation signs | Darkening, harsh/woody off-odour (turpentine-like), rising peroxide value (> 2.0) |
- Peroxide value is the freshness control: fresh batches stay below 1.0 meq O2/kg; a value approaching 2.0 signals you should use the oil soon
- Partially used drums should be topped with nitrogen or moved to smaller containers to reduce headspace
- Do not store in direct sunlight — UV accelerates limonene oxidation and fades the natural green colour
- Because the oil is flammable (flash point ≈45°C), store away from ignition sources and follow local flammable-liquid storage rules
- If you re-bottle into smaller units for resale, transfer under nitrogen and date every new container
