Perfume Longevity Guide: Concentrations, Hours and What Actually Makes Scent Last

Concentration describes the percentage of aromatic compound dissolved in alcohol and water. Higher percentage generally means longer wear, but 'eau de parfum' is not a regulated term: one house's EDP can be weaker than another's EDT. Use the table as a starting expectation, then trust the specific fragrance.

• Extrait de Parfum — 20-40% oil, 8-14+ hours
• Eau de Parfum — 15-20% oil, 6-10 hours
• Eau de Toilette — 5-15% oil, 3-5 hours
• Eau de Cologne — 2-5% oil, 2-3 hours
• Eau Fraiche / mist — 1-3% oil, 1-2 hours

A 20% citrus cologne will still vanish faster than a 12% oriental. What lasts is what evaporates slowly: vanillin, coumarin, patchoulol, cedrol, santalol, labdanum resinoids, Galaxolide and Ambroxan. What disappears is what flashes off: limonene, linalool, citral, dihydromyrcenol.

This is why the longevity figures published across this database range from three hours for aquatic EDTs to fourteen for amber extraits — the family predicts the outcome better than the label does.

None of these require buying anything.

• Apply to clean, moisturised skin. Dry skin has less lipid film to hold aromatic molecules; an unscented emollient before spraying is the single cheapest longevity upgrade.
• Spray, do not rub. Friction generates heat and accelerates the top notes while physically breaking up the drying film.
• Target pulse points plus one fabric point. Skin gives warmth and evolution; fabric gives tenacity — wool and cotton can hold a scent for days.
• Layer with a matching unscented-base product rather than a different fragrance.
• Store the bottle upright, in the dark, below 20 C. Heat and UV degrade citrus and floral materials fastest; a bottle kept on a sunlit shelf can lose its top notes within a year.
• Do not judge longevity from your own nose alone. Olfactory adaptation means you stop perceiving your own fragrance long before others do — ask someone else.

Apply the same number of sprays to the same location at the same time of day, then check at fixed intervals (1, 3, 5, 8 hours) and record whether it is detectable at arm's length, on skin contact, or not at all. Three consistent trials tell you more than any published figure.
