概要

Essential oils for perfumery are extracted from plant materials primarily by steam distillation, a technique refined since the medieval Islamic Golden Age. Steam passes through plant material (flowers, leaves, bark, roots), vaporizing volatile aromatic compounds that co-distill with water. The condensed mixture separates into essential oil and hydrosol (floral water). While synthetic fragrance chemicals now dominate volume, natural essential oils remain critical for fine perfumery. Grasse, France remains the world capital of perfumery, and Bulgarian rose oil and jasmine absolute are among the most valuable natural products per kilogram.

化学プロセス

Plant material is loaded into a still and steam (direct or generated from water below the plant bed) is passed through at atmospheric pressure or slightly above. Volatile terpenes, terpenoids, and aromatic compounds (bp 150-300 degrees C) co-distill with steam at temperatures below 100 degrees C due to the reduced partial pressure of the immiscible mixture. The condensate separates in a Florentine flask — the essential oil floats (or sinks for some oils) and is decanted from the hydrosol.

No chemical reaction — steam distillation is a physical separation exploiting Dalton's Law of partial pressures. Terpenes (C₁₀H₁₆) and terpenoids co-distill with steam below 100 degrees C because the total vapor pressure exceeds atmospheric pressure when the partial pressures of water and oil sum.

原材料

  • Plant material (flowers, leaves, bark) — Cultivation (lavender, rose, jasmine, sandalwood, etc.) (Aromatic source)
  • Steam (H₂O) — Boiler (Distillation carrier and extraction medium)

最終製品

  • Essential oils (complex terpene mixtures) — Fine perfumery, aromatherapy, flavoring (Lavender (linalool/linalyl acetate), rose (citronellol/geraniol))
  • Hydrosol (floral water) — Skincare, food flavoring (rose water, orange blossom water) (Water-soluble aromatic compounds)

Environmental Impact

Essential oil production requires enormous quantities of plant material — 3,000-5,000 kg of rose petals yield just 1 kg of rose oil. This drives intensive agriculture and water use. Sandalwood and rosewood oils have contributed to deforestation of endangered species. Sustainable sourcing certifications and plantation cultivation are addressing these concerns.

安全性の考慮事項

最新のイノベーション

Supercritical CO₂ extraction produces higher-quality extracts without thermal degradation.
Microwave-assisted hydrodistillation reduces extraction time by 50-75%.
Headspace capture technology collects volatile compounds without harvesting the plant.
Biotechnological production of high-value terpenes (squalene, nootkatone) using engineered yeast is becoming commercial.
