Concentration

What does 30 to 35 per cent actually mean?

Almost every fragrance states a category and not a number. The number is the only part you can compare.

The ladder

Eau de Cologne3–5 %

Typically lasts one to two hours.

Eau de Toilette5–15 %

Two to four hours. The most common category in retail.

Eau de Parfum15–20 %

Four to six hours. What most people mean when they say “perfume”.

Extrait de Parfum, typical20–30 %

The highest tier commonly found in regular retail.

M’OUD Extrait30–35 %

30 per cent across the collection, 35 per cent in the Intense.

These ranges are industry convention, not legal definition — no rule states when a fragrance may be called an extrait. That is precisely why we give the number.

What follows from it

Less is more

Two or three sprays are enough. At this concentration a little carries further than expected — and 100 ml lasts accordingly.

Close, not loud

A high oil content does not automatically mean more projection. It means the fragrance stays longer and unfolds more slowly.

The materials carry it

The higher the share, the less can hide behind alcohol. That is pressure on the raw materials, not a marketing line.

Eine hohe Konzentration allein macht noch keinen guten Duft. Was danach passiert, entscheidet mit: Während der Reifung reagieren Alkohole mit organischen Säuren zu Estern — Molekülen, die weicher und runder riechen als das, woraus sie entstanden sind. Der Duft wird nicht besser, weil es jemand behauptet. Er wird besser, weil sich seine Chemie ändert.

These reactions run at their own pace. They cannot be hurried, only awaited. Oud Amal rests six months before it is filled.

Six months is capital tied up, warehouse space and delayed cash flow. Oud Amal rests six months in Switzerland before filtration and filling. That is why the duration is stated at all.

Und dann der Schnitt

Filtration ist eine Abwägung, keine Einstellung. Zu scharf gefiltert, verliert der Duft Körper — schwere Moleküle gehen mit den Trübstoffen verloren. Zu sanft, und in der Flasche bildet sich Schleier. Wo diese Linie liegt, wird pro Charge entschieden.

Die genauen Parameter bleiben beim Labor. Dafür hat man eines.

The other side

High concentration is not an advantage in every situation.

An extrait unfolds slowly. Judging it after ten minutes is judging it too early. It also sits closer to the skin than an eau de toilette — if you want a large cloud, you want something else. And in high summer a high concentration can simply be too much; that is what the lighter compositions in the collection are for.

If you want to know which of the four suits which occasion, that is in the comparison.
