The word “essence” used here is nothing more than a concentrate of perfume, in the form of oil or juice. These oils are extracted from a plant or wood extract according to the choice of the manufacturer, to give a good scent to your cologne.
These concentrated perfumes will then be diluted in denatured ethyl alcohol or ethanol with distilled water to neutralize the high amount of perfume in a finished product. And the freshness that we feel comes from alcohol accelerates evaporation.
