What extraction method is used to produce this Sea Buckthorn Seed Oil?
This oil is produced by supercritical CO₂ extraction — our standard and recommended method for sea buckthorn seed oil.
Why Supercritical CO₂
| Advantage | Detail |
|---|---|
| Solvent-free | No hexane / organic solvent residue |
| Low temperature | Preserves heat-sensitive nutrients (vitamin E, carotenoids) |
| Selective | Extracts oil without degrading fatty acids |
| Clean | No post-deodorization / refining needed for crude grade |
| Safe | CO₂ is inert, non-toxic, easily removed |
Process Overview
- Seeds cleaned, dried, milled
- Supercritical CO₂ extraction under controlled T/P
- Separation of oil from CO₂ (CO₂ recovered/recycled)
- Filtration, nitrogen flush, filling
- QC: fatty acid GC, peroxide value, acid value, heavy metals
No solvent residues are detected (COA reports "None / ND"). For a refined cosmetic grade, we offer a light deodorization step on request. Discuss your application — we advise on grade.
