Eau de toilette vs eau de parfum: what's the difference?
EDT vs EDP explained — the fragrance concentration ladder, how it affects longevity, projection and price, and how to choose. Plus where aftershave splash fits.
The short answer: eau de parfum (EDP) is more concentrated than eau de toilette (EDT), so it's richer, projects more, and lasts longer — while EDT is lighter, fresher and easier to over-apply by mistake. The two terms describe the same fragrance at different strengths, not different categories of scent. Here's the full ladder and how to choose.
The fragrance concentration ladder
"EDT" and "EDP" refer to how much fragrance oil is dissolved in the alcohol base. Roughly:
| Name | Typical oil concentration | Character |
|---|---|---|
| Parfum / Extrait | ~20–40% | Richest, longest-lasting, most intimate projection |
| Eau de Parfum (EDP) | ~15–20% | Rich and long-wearing; the all-day choice |
| Eau de Toilette (EDT) | ~5–15% | Lighter, fresher, brighter on the open |
| Eau de Cologne (EDC) | ~2–5% | Light and short-lived; a splash-and-refresh |
| Aftershave / splash | ~1–3% | Lowest; meant to scent the shave, not the day |
The percentages are industry conventions, not legal definitions, so they vary by house — but the order is consistent everywhere.
What the difference actually means for you
- Longevity. More oil means the scent lingers longer. An EDP commonly lasts most of a day; an EDT often needs a midday refresh.
- Projection & sillage. Higher concentration generally projects more and leaves a bigger "trail." An EDT sits closer to the skin.
- How the scent reads. Concentration can shift the balance — an EDT often feels brighter and more top-note forward, an EDP deeper and more centred on the heart and base.
- Price. More fragrance oil costs more, so the EDP of a given scent is usually priced above the EDT.
Same scent, two strengths: a concrete example
The clearest way to understand it is one fragrance offered at two concentrations. WhollyKaw's Fougère Bouquet comes as both an Eau de Toilette ($49.99) and an Eau de Parfum ($74.99). Same oakmoss-fougère composition; the EDT is the brighter, more wearable daytime version, while the EDP is richer and lasts longer. Choosing between them is about how strong and how long — not about which scent you like.
EDT or EDP — how to choose
- Pick EDT if you want something light and fresh, you reapply through the day, it's for hot weather or the office, or you're trying a scent for the first time.
- Pick EDP if you want to apply once and have it last, you like more projection, or it's for evening and cooler weather.
- Pick Parfum when you want maximum richness and longevity from a small amount, applied close to the skin.
Where aftershave splash fits
An aftershave splash sits at the bottom of the ladder — a low fragrance concentration meant to scent and refresh the skin right after a shave, not to perfume you all day. That's why a splash fades faster than an EDT and why, if you want a scent to last, you layer a matching EDT or EDP over it. Many WhollyKaw scents exist as a soap, a splash, and an eau de toilette/parfum, so you can match the strength to the moment.
Frequently asked questions
What's the difference between eau de toilette and eau de parfum?
It's the concentration of fragrance oil. Eau de parfum (EDP) typically holds about 15–20% oil, while eau de toilette (EDT) holds about 5–15%. As a result EDP is richer, projects more and lasts longer, while EDT is lighter, fresher and shorter-lived. They're the same scent at different strengths, not different scents.
Does eau de parfum last longer than eau de toilette?
Yes. Because EDP contains more fragrance oil, it generally lasts longer on skin — often most of a day — while an EDT frequently needs a midday refresh. Longevity also depends on the specific notes and your skin, but at equal everything, the higher concentration lasts longer.
Why is eau de toilette cheaper than eau de parfum?
Fragrance oil is the costly part of a perfume, and EDT contains less of it than EDP. So the EDT version of a given scent is usually priced below the EDP version. It's the same fragrance, just less concentrated.
What are the levels of fragrance concentration?
From strongest to lightest: Parfum/Extrait (~20–40% oil), Eau de Parfum (~15–20%), Eau de Toilette (~5–15%), Eau de Cologne (~2–5%), and aftershave or splash (~1–3%). The percentages are industry conventions that vary by house, but the order is consistent.
Which should I buy, EDT or EDP?
Pick EDT for a lighter, fresher scent you reapply through the day, for hot weather, the office, or trying a fragrance for the first time. Pick EDP when you want to apply once and have it last, with more projection, for evening or cooler weather. Some scents — like WhollyKaw's Fougère Bouquet — come in both, so you can choose strength without changing the scent.
How is an aftershave splash different from an eau de toilette?
An aftershave splash has a much lower fragrance concentration (about 1–3%) and is meant to scent and refresh the skin right after a shave, not to perfume you all day. It fades faster than an EDT. If you want the scent to last, layer a matching EDT or EDP over the splash.
