  4. 4. STEAM DISTILLATION
  5. 5. CARBONDIOXIDE EXTRACTION <ul><li>A relatively new method of extraction that is being employed is called carbon dioxide extraction, or CO2. This process utilizes the &quot;supercritical&quot; state of CO2, when it acts both as a gas and a liquid. </li></ul><ul><li>. The required equipment used for this method is quite expensive but yields a higher volume of essential oil, making more expensive oils such as frankincense widely available. </li></ul>
  6. 6. COLD PRESS EXTRACTION <ul><li>Most high quality citrus essential oils are obtained from a cold pressing of the rind or peel. This process is often called scarification </li></ul><ul><li>Many citrus essential oils on the market are bulk essential oils of inferior quality made by steam distillation of the peels rather than scarification. </li></ul>
  7. 7. ABSOLUTES <ul><li>Another method used to extract essential oils from plants is by using solvents. These oils are called absolutes. Absolutes are commonly used to extract the essence from very delicate plant parts like flower petals. </li></ul><ul><li>Common absolutes are Rose, Jasmine and Mimosa </li></ul><ul><li>These are used primarily for perfumery and blending </li></ul>
  8. 8. USES <ul><li>Aromatherapy </li></ul><ul><li>Room Freshening </li></ul><ul><li>Easy Inhalation </li></ul><ul><li>Massage </li></ul><ul><li>Insect Repellant </li></ul><ul><li>Beauty Products </li></ul><ul><li>Stress Relief </li></ul><ul><li>Perfumery </li></ul>
