The cost also plays an important role in the blending process. Aromatherapists must blend the right quantity and number of oils.

Their aroma profile changes and they go through the top, middle and dry out stages. This is when the volatility of the oils corresponds to three characteristic notes.

After this note evaporates, the oil goes through the middle note stage. This is when the body of the oil is the best, most balanced and provides the finest aroma. From this note, the base notes begin to develop slowly. During this middle stage, the base notes are more noticeable and the compounds are less volatile.

Finally the base notes evaporate and the dry out stage is entered. At this stage, the aroma of the oils is bittersweet and powdery indicating there is still a small bit of the oil present. Based on individual aromas, essential oils also can be classified into the various notes.

  • Clary sage – middle note
  • Patchouli – base note
