extraction.
What is it and how to extract essential oil from a flower from a plant, a peel.
What information do ask when you buy a oe to the store or online.
What is a hydrolat or aromatic water.
Extraction by water vapor stream
The plant or the flower is placed on the grids or supports and is made through a current of steam.
Heat "takes out" the oil upward.
Following the cooling we are oil and water below the surface, because the oil is lighter and floats.
is divided and then collect the oil from separating.
As you can see, the oil will be a very concentrated extract of active ingredients, so powerful that we must be careful to handle it (it will be the subject of Chapter No. 2).
This is the essential oil.
Even the water used in the plant, however, is something we have the famous aromatic floral water or water or hydrolat.
(this is the real hydrolat and not tap water with added perfuming molecule synthetic product that is more easily find that plain water scented. Be noted that our noses probably prefer the latter because, alas, we all used to the synthetic me understood, and it takes a while to appreciate the true natural perfumes).
Extraction by cold pressing
is made for citrus, whose peels are squeezed to obtain oil.
It 's a simple task that intuitively we have done many times squeezing an orange peel in his fingers and warning the "oiliness".
method of 'effleurage
It' s a method which consists, in short, to absorb the scents of the flowers of a plate coated with grease. It 'an old method.
solvent extraction using solvents of various forms to extract the oil.
I suggest to all to use the oils extracted by steam current or by cold pressing.
The other two methods I have just summarized, and although some may be suitable for extraction are not possible with other methods, personalmente non mi piace l'uso di sostanze diverse dall'acqua (vapore) che vengono in contatto con la pianta o il fiore.
Anche perchè è più difficile appurare la natura di queste sostanze per noi acquirenti.
Il metodo di estrazione viene indicato sulla confezione o sulla scheda tecnica dell'olio essenziale.
Pretendete di conoscere sempre questo metodo.
E' molto frequente trovare olii non puri e mischiati a solventi vari e con metodologie che non salvaguardano le qualità della pianta o del fiore.
Anche affidarci al naso è molto difficile (se non per espertissime/i) perchè l'aroma dell'olio essenziale non si riconosce esattamente dalla "somiglianza" con la pianta di provenienza: il livello concentration of active ingredients is very high compared to the plant base and recognition of its aroma is rather when we dilute a drop in hot oil (or alcohol white).
Keep in mind that a 10 ml vial for easy use at home we will take at least a couple of years, just to understand the strengths (minimum) that are usually used.
So the first lesson, we expect oil and pure 100% natural.
already ask for the extraction method and see it in black and white is a guarantee in this regard.
If it does not say anything, we can not know how the oil is extracted.
In this case you can also get contact the manufacturer and ask for clarification by phone or by mail.
Note: wanting to be picky, there would be also different degrees of distillation of essential oils to keep in mind, but then we enter an area and use a different and more specific to them.
My interest and my treatment only want to understand the scope of the do-it-yourself cosmetic, fragrance of the creams, detergents and environments. Aromatherapy I keep this because you can not ignore it when you have a hand in o (and explain it well in the next chapter), but I do not go much beyond the cosmetic and therefore use only a limited range of oils.
not it is said that in future I enjoy natural perfumery real ..... but not for the moment.
