How to Choose a Perfume Concentration
The words are oil percentage, roughly. Parfum is denser and usually longer. EDT is lighter and cheaper per bottle, not per hour.

Percentages are bands, not laws
Houses fudge the terms. An ‘EDP’ can be weaker than another house’s ‘EDT.’ Treat the letters as a hint: more oil usually means more intensity and a higher price per millilitre, not a guaranteed 12-hour miracle.
Cologne in the old sense is light and citrus. ‘Eau de cologne’ on a modern designer bottle may just mean a splashy marketing word. Smell it.
Pick for climate and manners
Heat and an open office: EDT, 1–2 sprays. Winter coat and dinner: EDP or parfum, still 2 sprays, not 8. A 50ml EDP you finish in two years is better than a 100ml parfum you save for a fictional gala.
| Label | Typical oil | Usual use |
|---|---|---|
| EDC / cologne | 2–5% | Heat, splash, short |
| EDT | 5–12% | Day, office, summer |
| EDP | 12–18% | Default signature |
| Parfum / extrait | 20–40% | Evening, pulse, fewer sprays |
Money per hour, not per bottle
A $90 50ml EDP at two sprays a day can be cheaper than a $60 100ml EDT you need four sprays of. Decants ($8–$25) exist so you do not learn this with a full bottle. Store away from light; juice oxidizes like other cosmetics.
Questions, answered
- Does parfum always last longest?
- Often, not always. Heavy base notes last. A citrus parfum can still be gone in three hours.
- Can I layer EDT and EDP of the same scent?
- Yes, if they are the same DNA. Do not create a fog.
- Is oil-based perfume a concentration?
- It is a different format — oil on skin, usually intimate, no spray cloud. Apply with the same restraint.
