I. History

They have been around since antiquity and credits were given to early Egyptians when they employ essential oils for cosmetics, perfumery, and embalming purposes. Examples of essential oils are peppermint, sandalwood, Citronella oil, lavender oil, and eucalyptus etc. Based from the example given, essential oil is named from the plant material from which it was extracted.

II. Production

Essential oils are produced in different ways. Most are produced by distillation (steam distillation). Distillation is a process of separating liquids of different vapor pressure. In chemistry we learned that a substance with higher vapor pressure has a lower boiling point. The next paragraph illustrates this process. In this process, the plant material are held in a pressing material or kept in a certain container where liquids will be allowed to evaporate. Liquid substances in the plant material with lower boiling points are distilled first while allowing liquid material with higher boiling points to remain as in the case of essential oils. Still, other essences (essential oils) are so hard to extract that they need to undergo a series of complicated process. Jasmine and rose oils are examples. They undergo rigorous distillation process, first by being washed in a sea of solvent material (supercritical carbon dioxide or hexane) to extract a mixture of essential oils (concrete) derived from the process. The concrete will then have to undergo a second phase of distillation process using alcohol-based products, to effectively separate various volatile oil (absolute) products from the distilled material.

III. Uses

Due to their characteristic volatile (readily vaporizable) and molecular properties, essential oils possess characteristic odor, and can be appreciated through smelling, skin application and ingestion.
