Concentration — the number that decides everything
When two perfumes with the same scent behave completely differently — one vanishes before lunch, the other stays until dinner — the answer is almost always essence concentration. Concentration is the percentage of the liquid that is actual perfume oil; the rest is mostly alcohol and water.
The standard concentration levels
- Eau de Cologne (EDC): 2–5% essence. Light freshness, lasts 1–2 hours.
- Eau de Toilette (EDT): 5–15% essence. The most common summer format, lasts 2–4 hours.
- Eau de Parfum (EDP): 15–20% essence. The standard for designer perfumes in stores, lasts 4–6 hours.
- Extrait de Parfum: 20–40% essence. The highest spray grade — less alcohol, more scent, lasts 8+ hours.
- Oil Perfume: alcohol-free oil base. Releases slowly from the skin, lasts 6–10 hours and sits closer to the body.
Why does store EDP feel "strong" but fade fast?
EDP's alcohol evaporates quickly and creates that first burst of scent — which is why it feels intense in the opening minutes. Once the alcohol is gone, only the real essence remains (15–20%). A 40% Extrait works the other way round: it opens quieter, but its scent curve falls far more slowly.
Spray or oil — which should you pick?
It depends on the use case. Spray (Extrait) projects more — people around you notice your scent; right for evenings and events. Oil is more intimate — the scent stays on your skin like a personal aura; ideal for the office, long days and dry skin (oil doesn't dry the skin the way alcohol does).
