Generalities on essential oils

 

General definition of essential oil

Essential oil is a volatile and fragrant substance secreted by aromatic plants. secretive pockets can be located both at the aerial parts (fleurs, uilles, stems and branches) and underground organs (racines, rhizome).
According to iAfnor (French Standards Association), essential oil means a product obtained from a raw material (of which it bears the name) by simple distillation or by mechanical expression.

 

Manufacture of essential oil

A real essential oil is a natural product extracted from aromatic plants. Extraction can be made from flowers, leaves, roots or seeds.

Two processes manufacturing are mainly used:

  • 1- cold extraction :
    Reserved for various citrus (pepperfruit, tangerine, ...), the cold expression is to subject the plant substance to high pressure using a hydraulic press.

  • 2- steam trainingdistilation :
    A heat source (1) heats an alambic that contains water (2) and plants placed on one or more trays (3). heat leads to the formation of steam that passes through the plants and carries with it the aromatic molecules. this steamer enters the capital 'silver head' (4) and then in the collar (5). the steam charged with the aroma then condenses through a refrigerant tank (6). the liquid that comes out of this tank (7) is a mixture of water and essential oil. this liquid is recovered in a wiper where, in the general case, essential oil (8), lighter, separates from water (9). This water, called hydrolat or floral water, contains less than 5% he. loaded with soluble aromas and mineral elements present in the plant, this floral water is a remarkable natural cosmetic product. its subtle properties give it a gentle and secure approach to baby aromatherapy.

The essential oil obtained by distillation is a vegetable essence modified by oxidation and hydrolysis. a controlled temperature and low pressure are essential to maintain an aromatic quality and chemical composition as close as possible to the plant essence that is sought to extract.

Extraction solvent is also used for some essential oils, concepts or absolutes are obtained (alcohol).

 

Distillation yield

Yield means the amount of essential oil obtained from an initial amount of vegetable material.

It is expressed in % and variable according to i's species and distilled parts. This explains the differences in prices or mode of conditioning of essential oils. examples:
- eucalyptus, leaves: 1 -3%
- geranium, air parts: 0.10-0.15%
- rose, petals : 0.015- - 0.020 %

 

But an essential oil, what is it ?

orange

Essential oil is the natural secretion of the plant. It is developed by its secretive organs which are located in the different parts of plants and aromatic trees: seeds, root, wood, leaf, fruit and flower.

When you press an orange bark over a candle, hundreds of small stars light up on the flame. It's from the gasoline orange. It is this precious product that scents all the fruit.

 

How does essential oil work ?

derme

Whatever way to use it, essential oil will be transported by the blood system. the finesse of the molecules will allow it to cross the epidermis as well as the pulmonary alveoli.
Unlike medications, essential oil does not remain in the body. It will be expelled by urine, stools, sweat and expiration.

 

Not to confuse essential oil and petrol

citron

Gasoline is a natural aromatic substance secreted by the plant. for citrus fruit, the essence is extracted by expression of zest. We should say lemon essence and not lemon he.
During its transformation by distillation the gasoline undergoes a biochemical modification and becomes he. Essential oil is therefore the essence of the distilled plant.
It is made up of volatile molecules. a pure and natural essential oil contains no fatty bodies.

 

essential oil "pure and natural?"?

etiquette

The name "pure and natural" guarantee that essential oil comes only from the plant indicated on the label. it is neither mixed nor cut with molecules of other essential oils or synthetic molecules. because essential oil is expensive, falsifications are indeed numerous. certain production practices use additives to improve yield, which significantly affects the quality of essential oil thus obtained. but the available oils are of uneven quality and some manufacturers observe stricter criteria than others. many parameters can change the quality of an essential oil: the conditions and the place of harvest, fertilizers and pesticides used.
Preferably, require organic essential oil, which, in order to respect a specifications, guarantees a minimum of quality.

 

Why are they so expensive ?

melisse

The high price of certain essential oils is linked to the amount of plants necessary for its realization.
Thus, to obtain 1 kg of essential oil of melica, it takes between 4 and 12 tons of melica according to the chosen process. Careful, unscrupulous people can sell you lemongrass for lemongrass. if the smell is close, their properties are totally different.
Then pay attention to cheap essential oils !there are in france real producers, in love with their trades, who market essential oils of excellent qualities but it requires a lot of work (hand-wrapping plants, long distillation,. ) and the price goes with !

The essential oils we offer on our website are neither the best, nor the cheapest, but they have excellent value for money.

 

Use of essential oils
