Essential oils are steam volatile oils distilled from plant materials and represent the typical flavour and aroma of a particular plant. They are found in flowers, leaves, roots, seeds and barks and find use principally in perfumery and flavourings. They are thus low-volume, very high value products. This makes them attractive crops for remote smallholders where high transport costs prevent the transport of lower value cash crops.
Table 1 shows the important constituents of some common essential oils. Table 1 - Essential oils The quality of the oil obtained from a particular species will be influenced by where it is grown and how it has been processed. New producers are likely to meet with resistance from buyers as this is a very conservative market depending to a great extent on trust regarding supply and quality.
Once established trading relationships are made, however, reliable markets can be gained. Lemon, lime and orange oils are also produced in very large amounts. Correct harvesting is very important. The essential oil content varies considerably during the development of the plant and even the time of day.
If the plant is harvested at the wrong time, the oil yield or its quality can be severely reduced. Essential oils are usually contained in oil glands, or veins that are fragile. Poor handling will break these structures and release the oils resulting in losses.
This is the reason a strong smell is given off when these plants are handled. The first harvest can take place months after planting. Then the grass can then be harvested up to four times a year. If harvested too often, the productivity of the plant will be reduced and the plant may even die. If the plant is allowed to grow too large, the oil yield is reduced. For lemongrass it should be 1. The grass should be harvested early in the morning as long as it is not raining.
Harvesting can be done with machetes or simple knives. Harvesting involves the removal of bark from stems measuring 1. This takes place early in the morning.
The main obstacle to correct harvesting is the crop being picked immature. This is usually due to fear of theft or the farmer requiring money urgently. The preparation of the material for distillation varies. Some materials, and in particular flowers, should be distilled as quickly as possible. Many herbs are left to wilt, or are dried before distillation while barks, seeds and roots can be dried and stored for several months prior to distillation. Information on small scale drying systems can be found in the Practical Action Technical Briefs on drying.
As oil is lost during drying care needs to be taken and low temperatures used. Allowing leaves to dry in the shade or partial shade will result in less loss than direct sun drying. It is vital that the material is dried to a moisture content that is low enough to prevent the growth of moulds and typical moisture levels are shown in Table 2. The dried product should be stored in a cool place and protected from any pick-up of moisture. This section examines the three common methods of distilling essential oils first examining the stills used and then condensers and oil separation methods.
Two stills are shown in Figure 1 below. This small still has a combined condenser on the top of it, shown in section. Cold water is put into the open pan and condensation collects in the dome. The plant material is totally immersed in water and boiled.
The steam and oil vapour is condensed and the oil is separated from the water using the system described below. The stills used are simple and find wide use amongst smallholder farmers, They are often heated over an open fire, which if not carefully controlled, may result in local overheating and burning of the charge.
The quality of the oils produced in such traditional stills can be improved if they are heated by steam generated in a separate boiler. This, however, requires more expenditure in capital equipment. Water distillation remains the recommended method for barks, such as cinnamon and sandlewood, and certain flowers.
The charge of plant material is supported on a mesh or grill above boiling water as shown in Figure 2. The water is boiled, either over a fire or by steam from a boiler using a steam coil or jacket. This system greatly reduces local overheating and burning of the charge. It is important that the charge is packed evenly and not too tightly into the still.
Over-packing will result in back-pressure and the steam finding channels through the charge leaving zones that have not been extracted. The charge is again supported on a mesh above the base of the still and above a steam coil as shown in Figure 3. All still bodies should be insulated to reduce heat losses and fuel consumption. In some cases they are mounted on frames that allow them to be inverted in order to rapidly remove the hot charge after distillation.
For the reasons described below, in many cases, the use of expensive stainless steel is not necessary. Condensers Steam containing the essential oil vapour leaves the still via a head, known as a gooseneck, and passes to a condenser as shown in Figure 4.
Simple condensers consist of a metal coil in a tank of flowing cold water. Ideally the coil of the condenser should be constructed from an inert material such as stainless steel in order to prevent the oil chemically reacting with mild steel.
In many traditional stills the gooseneck and condenser coil were constructed from copper or brass that had been internally tinned to provide a reasonably inert surface.
It is very important that the condensed steam water leaving the condenser is thoroughly cooled. If it is still warm there will be a loss of essential oil. The final step in the distillation of essential oils is the separation from the water flowing from the condenser using a special flask called a Florentine.
This is a very important stage as small quantities of oils of very high value are being handled and maximum efficiency is the key to profitability.
Most essential oils are lighter than water and float to the surface of the Florentine. Some ion oils, however, are denser than water and sink to the bottom. For this reason two types of Florentine are used as shown in Figure 5. It is common practice to link several Florentines together. Most of the oil will separate in the first flask but some will pass over with the water to the second, third etc.
This is usually done by letting the mixture settle in a large container made of glass. If the oil is heavier than water, the oil is collected from the bottom of the container, and if lighter from the top. If the water is cloudy after separation, it should be returned to the distillation unit and redistilled.
This is called 'cohabitation'. At the end of the distillation the oil and water in the Florentines is placed in a large laboratory separating funnel Figure 6 and allowed stand for several hours after which the water can be run off. At is stage a small plug of cotton wool is often placed in the outlet of the funnel. As the oil runs through the plug any final traces of water are removed. The oil should be stored in brown glass bottles or drums, tightly closed and with the minimum possible headspace as oxygen in the air reacts with many oils.

Steam distillation, the extraction method used most commonly to create essential oils, uses high heat that can cause the delicate petals to deteriorate and form a dense mass that steam cannot penetrate, rendering the precious oil impossible to extract from the petals.

Essential Oil Production
The second edition of this book is virtually a new book. There are comprehensive essential oil profiles and almost references. There are new chapters on the respiratory system, the cardivascular system, the urinary system, the digestive system and the nervous system. For each essential oil there is a full breakdown of constituents, and a clear categorization of hazards and risks, with recommended maximum doses and concentrations.
Essential oil , highly volatile substance isolated by a physical process from an odoriferous plant of a single botanical species. The oil bears the name of the plant from which it is derived; for example, rose oil or peppermint oil. Such oils were called essential because they were thought to represent the very essence of odour and flavour.
Across the Mediterranean region aromatic plant species growing naturally. These species are producing essential oils and comprise an important economical indicator for the population. All aromatic plants emit volatile substances into the environment either during their life or during the decomposition process. These volatile constituents affect the top soil microflora and form specific environmental conditions for the recycle process.

From the very first hair, we noticed a difference in colour in each of us. Steve had two thick brown hairs for a first mustache growth , Bill had a fine, red, frizzy hair and John had an almost golden blond hair. It was finally the opportunity for us to stand out from our friends. A few years later, when our beards started to grow , we realized that their texture was different in each of us. Our beard oils are designed with the utmost respect for your beard and skin.

An essential oil is a concentrated hydrophobic liquid containing volatile easily evaporated at normal temperatures chemical compounds from plants. Essential oils are also known as volatile oils , ethereal oils , aetherolea , or simply as the oil of the plant from which they were extracted, such as oil of clove. An essential oil is "essential" in the sense that it contains the "essence of" the plant's fragrance—the characteristic fragrance of the plant from which it is derived. Essential oils are generally extracted by distillation , often by using steam.
The obtained adhesive film will inhibit growth of a wide range of microbes and will be suitable for high-touch surfaces, providing a durable protection with good resistance. It will assure the highest level of hygiene and patient safety, reducing the use of disinfectants. These objectives will be achieved, using a multi-functional approach combining prevention of adhesion with killing of microorganisms, by means of essential oil emulsions embedded in a micro and nanopatterned polypropylene matrix. From bed rails, tray tables, telephones and alarm buttons to furnishings, door handles or taps: Hospitals are hotbeds for bacteria, which can lead to life-threatening infections in fragile patients. These films are applied to large-area surfaces around patients in order to reduce the risk of contamination.
