Creation of Magical Elixirs: 5 Methods of Making Essential Oils 

Before you buy essential oils, know about how they are made, as it will give you a better insight into their value for money offerings. Thus, here are the different methods used in making essential oils:

  • Steam Distillation

This is the primary and the most authentic way of making essential oils, as it retains their therapeutic properties despite the use of direct heat. In this method, the plant materials, i.e., flowers, herbs, bark, roots, etc., are passed through steam, which helps release essential oils from the natural ingredients. Initially, the oils are in vapour form, which are then rinsed and passed through a cooling system, condensing them into liquid. This method is mainly used to extract the purest essential oils from natural elements, except citrus-based plants.

  • Cold Pressed Extraction

Commonly used for the extraction of essential oils from citrus fruits, this method involves putting pressure on the outer skin of the fruit. After grinding the peel with appropriate pressure, it starts excreting a liquid. This liquid is then put into a centrifuge so that oil can be separated from it. This method has to be quick so that oxidation can be avoided, resulting in premium-quality essential oils.

  • Solvent Extraction

This method of making essential oils involves soaking the natural ingredients in a solvent to draw the fragrance out in the form of a liquid. This liquid is called ‘absolute.’ However, it is in a mixture form. The mixture is processed many times so that the absolute can be separated from the solvent. This method of extraction is usually used for fragile natural ingredients like flowers.

  • CO2 Extraction

Under this method, carbon dioxide is used as a solvent to extract essential oils from natural elements. Here, the CO2(carbon dioxide) is made to reach a certain temperature, where it is believed to enter into a supercritical stage, i.e. somewhere between gas and liquid form. Further, the temperature of the carbon dioxide is manipulated to bring it back to the gaseous form, where it breaks down completely, leaving behind an essential oil-like compound. 

  • Enfleurage

Although this method isn’t commercially viable today, many modern processes take inspiration from this ancient essential oil extraction method. It involves harvesting specific flowers and a complex system of exposing them to diverse oils for days on end. It results in a thick mixture called pomade, which is further either heated or exposed to alcohol. It results in an aromatic essential oil formation.
