Essential Oil Extraction Processes


There are several processes used in the production of essential oils; each in turn applied to the various plant matter being used to produce a specific oil; the most common method is Steam Distillation.

In steam distillation raw organic material is loaded directly into the distillery, which basically operates with the same principals as a large pressure cooker. Traditionally, the steam is produced outside the pot, and is piped into to mix with the vegetative material. Under pressure, the steam draws out the plant oils, which are then forced from the container and sent through a cooling chamber where the oil and water mixture turns from steam into a liquid form.

As the water/oil mixture cools it condenses; the ingredients begin to separate with the lighter and purer oil floating on top, and the heavier base water content sinks to the bottom.
The oil is syphoned from the mixture and is ready to be used in the fragrance and aromatherapy/health industries as pure raw essential oil.

The remaining diluted oil/water mixture is also harvested as an oil hydrosol, and can be utilized in many soap, cleaning products, shampoos, conditioners, and cosmetic making markets and industries.

Cold Pressing is another very successful method of extracting oils, and is especially used for extracting delicate oils of citrus type fruits. In this system raw plant material, namely the peels, are soft pressed without the use of heat. Most Carrier Oils are derived from plant material in this manner thusly preserving the living essence of the plant.
Solvent Extraction is the method utilizing special solvents; the resulting Absolute Oils are extremely pure and highly concentrated. It is a delicate procedure to remove an aromatic substance from living plant matter using solvents. In the process, plant matter is crushed in order to break down the molecular structure of the plant material, and then left to be soaked for a period of time in solvents. The plant oil then forms a waxy substance, which is then mixed with an alcohol solution. Then through a distillation process the solvents are evaporated and the oils are then removed producing a very high quality Therapeutic product.

The fourth popular extraction procedure incorporates an infusion process where raw plant material is allowed to soak for a reasonable amount of time in base carrier type oils such as soy and olive oil.

This allows the oil to receive the essence of the flower and is used specifically in the production of Infused Essential Oils that are used extensively in the aromatherapy practices.
Carrier Oils are base oils derived from vegetable based plants; they are very high in quality and in epidermal nutrition. Carrier Oils are used extensively in Massage Oils and as a dilution medium of highly concentrated Essential Oils, allowing them to be applied directly to the skin in topical applications. These oil blends make an excellent choice for promoting health and adding lustrous beauty to your skin, and nutritional support to your body and hair.
Carrier Oils can be obtained through cold pressing of nuts, roots, bark, grains, and seeds of plants
