A Blog about my love in perfumes, the aesthetics, the hedonism, the greatness of these artistic creations of the olfactory world. It is about my wish, my dream to create something like this one day.

Evaporation Model Incorporating Top, Middle and Bottom Notes.

An Essay on the Evaporation Curve
Within the entire perfume, which I shall call total evaporation curve, there are a mix of 3 evaporation curves, ie. Of the top, middle and bottom notes.

In these three, they blend together to form a harmonous total evaporation curve.

Quantity of MaterialsThe top notes start at the top and mostly evaporate by the time they reach middle of the evaporation curve. The middle notes are perceivable I the start of the evaporation but takes the greatest effect in the middle of the evaporation cycle and the bottom notes become more and more perceivable by the time the end of the evaporation cycle is reached.

Total Evaporation Curve

The total evaporation curve will determine how much the top, middle and bottom notes are in the perfume. For heavy perfumes, more bottom notes are being used. For fresher perfumes more top notes are being used. Perfumes with large amounts of bottom notes, like orientals, chypes etc. Well Balanced perfumes with equal proportions of top notes, middle and bottom notes, eg. Florals, aldehydics etc. Citrus Type perfumes, or fresh perfumes with a high percentage of top notes

Materials linkage within Evaporation Curves

The role of a perfumer is to find materials that blend well a single note within a perfume to form distinct Notes within the perfume. For example, a floral perfume will consist of a blend of Rose, Muguet and Jasmin notes. The perfume will design these three notes with Rose top notes, Rose middle notes and Rose bottom notes, and like wise for muguet and jasmin. The “idea” of the perfume is carried through from top to bottom this way and a good harmony is achieved.
