How do you ensure batch-to-batch consistency of this ylang ylang oil?
Batch-to-batch consistency is guaranteed by a controlled supply chain — fixed origin sourcing, standardized distillation, and full GC-MS verification of every lot against ISO 3063 before release.
Consistency System
| Control point | Measure |
|---|---|
| Sourcing | Fixed origin (Madagascar/Comoros/Indonesia) and distilleries for stable profile |
| Distillation | Standardized run time, temperature and fractionation parameters |
| Blending (if needed) | Blending of similar lots to normalize composition |
| Testing | GC-MS fingerprint of every batch vs ISO 3063 ranges |
| Documentation | COA with full composition and grade per batch |
| Retention | Retained sample of every batch kept for reference |
- Grade targets (Extra/Complete/3rd) are set at the sourcing stage, not just at testing
- Release criteria: every batch must pass composition, physicals and contamination tests
- Slight natural variation (within ISO ranges) is expected and accepted by the industry
- Retained samples allow objective comparison if a discrepancy arises later
- Any corrective action is documented and traced back to the source
