Fragrance Concentrations Explained: EDT, EDP, Extrait and Pure Parfum

If you have ever wondered why one bottle says eau de parfum and another of the same scent says eau de toilette, you are asking the single most useful question in perfumery. The answer is concentration: how much fragrance oil is dissolved in the carrier. That one number shapes how strong a scent reads, how long it lasts, how far it travels, and what you pay. This guide walks the full spectrum, from the lightest eau de cologne up through extrait de parfum and the often-overlooked world of pure parfum and oil-based, attar-style perfumery. Along the way we will bust a few myths, because higher concentration is not the same thing as a better fragrance, and it is not the only factor that matters. Every fragrance named here is one we carry as a decant, so you can test these concentrations on your own skin first.

What "concentration" actually means

A finished fragrance is mostly carrier with a percentage of aromatic compounds (the "oils" or "juice") dissolved into it. In conventional perfumery that carrier is high-grade perfumer's alcohol. The percentage of aromatic compounds is what the familiar labels describe. The figures below are widely accepted industry ranges rather than legally fixed rules, so a given house may sit a little above or below them, but they hold up well as a map:

• Eau de Cologne (EDC): roughly 2 to 5 percent oils. Bright, fresh, fleeting. Expect 2 to 4 hours on skin.
• Eau de Toilette (EDT): roughly 5 to 15 percent. Lighter, top-note driven, an easy daytime wear. Expect 4 to 6 hours.
• Eau de Parfum (EDP): roughly 15 to 20 percent. The modern standard: balanced strength and longevity. Expect 6 to 8 hours.
• Extrait de Parfum (also called parfum or pure parfum in the alcohol sense): roughly 20 to 30 percent, and sometimes higher. Rich, deep, long-lasting, often 8 to 12 hours or more, usually with intimate rather than loud projection.

Two ideas matter more than memorising the numbers. First, a higher percentage does not simply make a scent "louder." It changes the balance, letting heavier base notes speak and giving more staying power, but often projecting closer to the skin, not further. Second, the percentage tells you nothing about quality: a beautifully built eau de toilette will always outclass a poorly made extrait. Concentration is a dial, not a score.

Eau de Cologne: the fresh, fleeting opening

Eau de cologne is the lightest mainstream concentration, traditionally built around bright citrus and herbs. It is made to refresh rather than to last, which is exactly its charm on a hot day. A lovely in-stock example that quietly upgrades the genre is Bortnikoff Musk Cologne: juicy tangerine, sweet orange and lemon over green tea and soft white florals, but grounded by real natural musk and sandalwood so it holds on far longer than a typical cologne. It shows how materials and construction can stretch what a concentration "should" do.

Eau de Toilette: the everyday workhorse

Eau de toilette sits a step up, with enough oil to carry through a workday while staying easy and unobtrusive. It leads with its top and heart notes, gives a clean lift on application, and then settles politely. It is the genre most people reach for casually, in offices, and in warm weather. One honest note for niche shoppers: many artisan and luxury houses skip EDT entirely, releasing their work at eau de parfum strength or higher to capture more of the costly raw materials they use. Most of the perfumes in our own collection sit at EDP and above for that reason, so if you love the lightness of an EDT, look for fresh, citrus-forward compositions and apply a little more generously.

Eau de Parfum: the modern default

Eau de parfum is where most contemporary fragrance lives, and for good reason. At roughly 15 to 20 percent it balances presence, longevity and wearability better than anything else, which is why it has become the default for new launches. A great in-stock EDP that shows the range's versatility is Creed Virgin Island Water: lime and bergamot snapping over coconut milk and jasmine, drying down to a warm, skin-close musk. It reads fresh enough for heat yet carries the depth and staying power you expect from an eau de parfum, the kind of scent that lasts an evening without shouting.

Extrait de Parfum: depth, warmth and longevity

Extrait de parfum (often just "parfum") is the richest alcohol-based concentration. With far more aromatic material in the bottle, the heavier base notes (resins, woods, ambers, musks) bloom fully, and the scent can last well over half a day. Crucially, extraits often sit closer to the skin than an EDP, trading reach for intensity and intimacy. Few pieces make this clearer than Amouage Interlude 53, whose "53" refers to its 53 percent oil load, an extrait pushed to the highest concentration the formula allows. The result is a dense, smoky cloud of incense, amber, oud and leather: dramatic, deeply long-lasting, and best in cold weather.

Here is the myth-busting part. Going up in concentration is not automatically an upgrade. A higher oil load can amplify notes you do not love just as readily as ones you do, and a heavy extrait can be overwhelming in a warm room or a small office. Concentration also reshapes a scent rather than merely magnifying it: Argos Triumph of Bacchus Extrait keeps the saffron, rum and orchard fruit of the original but swaps in a darker tobacco, Mysore sandalwood and vanilla base for a more nocturnal feel. It is not "better" than a lighter version, just a different mood. The right concentration is the one that suits the scent, the season and the occasion, not the biggest number on the shelf.

Pure parfum and oil-based perfumery: beyond alcohol

Now for the part most concentration guides leave out entirely. Everything above assumes an alcohol carrier. There is another tradition where the carrier is not alcohol at all but a precious oil or tincture. This is the world of attars and oil-based pure parfums, rooted in the perfumery of the Middle East, Persia and India, where botanicals were historically distilled into sandalwood oil and worn directly on the skin. Because there is no alcohol to flash off and carry the scent outward, an oil-based perfume behaves differently: it projects intimately, sitting close as a true skin scent, and it tends to last exceptionally long.

Our finest in-stock example of this approach comes from Ensar Oud, an artisan agarwood house whose master distiller hand-distils his own single-origin oud and musk oils. Take Ensar Oud EO2 Tonkin, offered in both an eau de parfum and a pure parfum that are identical in composition save for one decisive difference: in the pure parfum, a good part of the carrier is not plain ethanol but a proper deer musk tincture. The dilution itself is made of musk. That is what gives the pure parfum its extra richness, its deeper animalic muskiness, and its long, skin-close drydown built around Tonkin musk, castoreum and New Guinean oud. This is pure parfum in the truest, attar-lineage sense: the carrier is itself a raw material, not a neutral solvent.

The practical lesson is that "strength" is not one straight line. An oil-based pure parfum can have immense longevity and an unforgettable presence on skin while projecting far less than a sprayed extrait. If you love depth and intimacy over a loud trail, this is the corner of perfumery to explore.

So which concentration should you choose?

Match the concentration to the moment. Reach for an eau de cologne or a fresh eau de toilette for daytime, heat and the office, where lightness is a virtue. Choose an eau de parfum when you want all-day balance and reliable presence. Save extraits and oil-based pure parfums for cold weather, evenings and occasions where depth and longevity earn their place. Remember the two rules that cut through the marketing: stronger is not always better, and concentration is only one factor alongside the materials, the composition and how a scent behaves on your particular skin.

That last point is exactly why decants exist. Concentration interacts with body chemistry in ways no label can predict, so the smartest way to learn the spectrum is to wear it. You can sample any concentration, from a fresh cologne to a deer-musk pure parfum, in 2 ml, 5 ml or 10 ml decants, shipped worldwide. Browse all fragrance decants and try the whole spectrum on your own skin before buying a full bottle.
