Abstract:
     The characteristic of this invention consists in that it is not a one-step-method by which the essence of flowers is extracted directly, but a two-step-method by which the sweet essence from blooming fresh flowers is absorbed by an adsorbent and then the adsorbed essence oil is extracted and separated by supercritical (or liquid) carbon dioxide. The operation cost is thus decreased, the production of oil is increased, and the produced essence for hair oil has the sweet smell of fresh flowers.
