EDT, EDP, Extrait and Pure Parfum: What Concentration Actually Buys You

Eau de parfum vs eau de toilette, plus extrait, pure parfum and attar: oil percentages, longevity, projection and myths, with in-stock decant picks.

Amouage Interlude 53 is 53 percent perfume oil. The number is sitting right there in the name.

Most perfume you will ever own sits under 20 percent. That gap is the whole story of the letters on a label, and it shapes how a scent behaves on your skin.

Concentration simply means how much aromatic oil is dissolved in the carrier. Here is the whole map in one table.

These are widely used industry conventions, not legal rules, so individual houses vary.
Concentration	Typical oil load	Longevity	Projection
Eau de Cologne (EDC)	2 to 5 percent	2 to 4 hours	Bright but fleeting
Eau de Toilette (EDT)	5 to 15 percent	4 to 6 hours	Light and airy
Eau de Parfum (EDP)	15 to 20 percent	6 to 8 hours	Balanced, room-filling
Extrait de Parfum	20 to 30 percent or more	8 to 12 hours or more	Rich, often skin-close
Oil-based attar or mukhallat	Oil carrier	Exceptionally long	Intimate skin scent

Even the names on the bottom rung can mislead. Bortnikoff Musk Cologne is built like a classic citrus cologne, tangerine and lemon over green tea, but Bortnikoff bottles it as an eau de parfum and anchors it with a musk accord and sandalwood, so it holds on far longer than its name suggests.

Oil load and projection

The trap is reading that table as a volume knob. More oil mostly buys depth and hours, not reach. Plenty of extraits sit closer to the skin than the eau de parfum they were built from, trading projection for richness.

And the label only sets the ceiling. Creed Virgin Island Water is an eau de parfum on paper, but lime, coconut milk and jasmine over a skin-close musk is a deliberately airy build, and it is rated 4 to 6 hours with Moderate sillage.

Then there is Interlude 53, which takes its 53 percent and spends every point of it: incense, amber, oud and leather, rated 10 to 12 hours with Enormous sillage.

Now for the part most concentration guides leave out entirely.

What a bigger number changes

A bigger oil load amplifies the notes you do not love just as happily as the ones you do, and a heavy extrait will overwhelm a warm room or a small office.

It can also reshape a scent. Argos Triumph of Bacchus Extrait keeps the saffron, rum and orchard fruit of the original over the same base of tobacco, sandalwood and vanilla, but Argos pitches it warmer and deeper, with more sandalwood in the drydown. The right concentration is the one that suits the scent and the season.

When the alcohol itself smells

Now the corner most concentration guides skip. Everything above assumes the carrier is neutral. It does not have to be.

The old route is the attar, where the carrier is an oil, historically sandalwood oil, and there is no alcohol at all. Nothing flashes off, so the scent sits close to the skin and lasts unusually long.

The stranger route is the tincture. Ensar Oud EO2 Tonkin is released in one concentration only, Pure Parfum, and it follows the first EO No 2, whose pure parfum Ensar Oud said was diluted partly in real deer musk tincture rather than plain alcohol, so the solvent itself smelled. The dilution stops being a blank and becomes part of the perfume: a long, close drydown of Tonkin musk and castoreum over New Guinean oud.

Match the bottle to the moment

Cologne and a fresh EDT for heat, daytime and the office, where lightness is a virtue. An EDP when you want all-day balance. Extraits, pure parfums and attars for cold weather and evenings, where their depth earns its place.

And keep the two rules that cut through the marketing: stronger is not better, and no label can predict what a concentration does on your particular skin. That is exactly what decants are for. Try the whole spectrum, from a citrus cologne to a deer-musk pure parfum, in 2, 5 or 10 ml: browse all fragrance decants.

Frequently asked questions

Is extrait de parfum stronger than eau de parfum?
It carries more aromatic material, so it lasts longer and feels deeper. But stronger is misleading: many extraits sit closer to the skin and project less than a well-built EDP, trading reach for richness and staying power.

Does a higher concentration mean better quality?
No. A beautifully composed eau de toilette will outclass a poorly made extrait every time. The percentage tells you how a scent behaves and says nothing about how good it is.

What is an attar, and how is a tincture pure parfum different?
An attar is a perfume carried in oil rather than alcohol, a tradition rooted in the Middle East, Persia and India. A tincture-diluted pure parfum is different: the carrier is still ethanol, but ethanol steeped with a precious raw material such as deer musk, so the dilution itself adds scent.

Which lasts longer, EDP or EDT?
Usually the eau de parfum, because it holds more oil, roughly 15 to 20 percent against an EDT's 5 to 15. Materials and construction still matter, so a dense EDT can occasionally outlast a light EDP, but the odds favour the EDP.
