Parfum, EDP, EDT, EDC: what the concentration actually means
The letters on the bottle tell you how much fragrance oil is in the mix — and that changes the price, the projection, and how long a scent lasts on your skin.

Two bottles from the same house can carry the same name and smell noticeably different. Usually the reason is printed right on the label: the concentration. It is the ratio of perfume oil to alcohol and water in the formula, and it drives almost everything you notice about how a fragrance performs.
The scale, strongest to lightest
| Name | Common abbreviation | Typical oil content |
|---|---|---|
| Parfum / Extrait | Parfum | 20–30% |
| Eau de Parfum | EDP | 15–20% |
| Eau de Toilette | EDT | 5–15% |
| Eau de Cologne | EDC | 2–5% |
| Eau Fraîche | — | 1–3% |
These are ranges, not rules. Houses set their own formulas, and a well-built EDT can outperform a weak EDP. Treat the label as a strong hint, not a guarantee.
What higher concentration changes
Longevity. More oil means the scent lingers longer. A parfum can still be there the next morning; an eau de cologne may fade within two hours.
Projection and sillage. Higher concentrations tend to sit closer to the skin and last, while lighter ones bloom outward and then dissipate. This is why an EDT can feel “bigger” in the first hour even though the EDP lasts longer.
The character of the scent. Concentration is not just volume. Extrait versions often lean warmer and rounder, emphasising base notes like musk, amber, and wood. Lighter versions push the fresh, citrus, and green top notes forward. The same fragrance can feel like a different season depending on the version.
Price. More perfume oil costs more to produce, so parfum and EDP sit at the top of a line’s pricing, with EDT and EDC below.
Choosing a version
- Hot, humid weather: lighter concentrations. Heat amplifies fragrance, and a parfum in July can become overwhelming.
- Cold weather, evenings, long events: EDP or parfum. You want something that holds up.
- Office and close quarters: an EDT applied lightly, or an EDP with one spray. Consideration for the people around you matters.
- Trying a fragrance for the first time: if the budget allows, sample the EDP. It is usually the “reference” version the house intends you to know.
A practical tip: buy the concentration that matches how you will wear it, not the one with the highest number. A parfum you apply once a week is worse value than an EDT you reach for every day.
The short version
The abbreviation predicts how strong, how long, and how expensive a fragrance will be — roughly. Match it to the climate and the occasion, compare prices across versions before you commit, and remember that the “weaker” bottle is sometimes exactly the one you want.
