How do you ensure batch-to-batch consistency of this tea tree oil?
Batch consistency is managed through chemotype selection, blending to spec and release testing — so successive shipments match your approved sample within ISO 4730 tolerances.
Consistency Management
| Measure | Detail |
|---|---|
| Chemotype selection | Plantations selected for high terpinen-4-ol / low cineole |
| Spec blending | Production blended against reference spec (terpinen-4-ol, cineole, terpenes) |
| GC-MS fingerprint | Every batch's volatile profile compared with reference |
| Physical checks | Density, refractive index, optical rotation per lot |
| Sensory panel | Organoleptic check before release |
| Retained samples | Kept for each batch for post-shipment comparison |
- Tea tree chemotypes vary with plantation and cut; blending irons out natural variation to hold the agreed spec
- Tolerances follow ISO 4730 ranges — batch-to-batch differences are kept well inside these limits
- A retained sample of every batch is kept for at least 24 months
- If your process needs tighter tolerances (e.g. terpinen-4-ol >38%), we agree a custom spec and blend to it
- For annual programs, we hold one 'anchor batch' profile and match subsequent lots to it
