Quelques termes liées à la parfumerie :

Absolute
The absolute oil is obtained from “concretes” or resinoïds. After extraction of these from alcohol ethylic absolute, the alcoholic solutions are freeze between -12° and -15° Celsius, filtrate and after that concentrate under reduce steam. The absolute oil is very precious for the richness that occurs for the compositions in which they are incorporate.

Dissonance
Break of harmony between the fragrant notes.

Head Space
New technique employing a vacuum process for the analysis of the volatile constituents of the fragrant products. This technique is made at three times; in the first place the took of the nice-smelling molecules emitted by the alive or not alive materials, secondly the analysis of the booby-trapped smell of materials, the identification and the quantification of molecules composing it by chromatographic analyses coupled with mass spectrograph, finally the formulation in laboratory with materials of synthesis. We can get faithful reconstructions.

Identical Nature (I.N.)
Product obtained in laboratory by chemical reaction of two or several bodies which can be stemming from natural essence or from the other materials without visible report with the perfume shop themselves. It would be false to say or to think that all the synthetic products come purely and simply to supplant the natural products. They offer a wide range of findings smells in the nature or the unknowns of this one. For example the ionone which does not exist in the violet, but the smell of which it exhales however. Synthetic products enrich the palette of the creator of indispensable products and high qualities.

Spectrometry
Physical method of analysis which complements chromatography in studying and testing elements, used in perfumery.
