An eau de parfum is a composition that contains 15 to 20% of aromatic extracts, diluted in 70 or 90° alcohol. The fragrant molecules are distributed into top notes, heart notes, and base notes; this is referred to as the olfactory pyramid.
Being concentrated, the perfume water has along-lasting hold, of6 to 8 hours. Compared to other formulas such as eau de Cologne or eau de toilette, perfume water is more concentrated; however, it is less concentrated than a toilette perfume which can contain up to 40% of aromatic molecules.
It is still advisable to use one's perfume sparingly. One or two sprays are generally enough to distribute all the scents on oneself. Furthermore, one should avoid repeating the action several times throughout the day, as there is a risk that the scent may become overpowering.
In order to prolong the fragrance, it is necessary to spray the perfume on strategic points. These are the pulse points such as the wrist, the nape of the neck, the crook of the elbow etc. To smell good all day, it is also recommended to spray the fragrance in the morning after showering. Indeed, hydration helps to fix the aromatic molecules.
