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

AdvantageDetail
Solvent-freeNo hexane / organic solvent residue
Low temperaturePreserves heat-sensitive nutrients (vitamin E, carotenoids)
SelectiveExtracts oil without degrading fatty acids
CleanNo post-deodorization / refining needed for crude grade
SafeCO₂ is inert, non-toxic, easily removed

Process Overview

  1. Seeds cleaned, dried, milled
  2. Supercritical CO₂ extraction under controlled T/P
  3. Separation of oil from CO₂ (CO₂ recovered/recycled)
  4. Filtration, nitrogen flush, filling
  5. 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.
