If you've ever compared price tags on two bottles that look almost identical, you've probably run into these three terms: Eau de Toilette (EDT), Eau de Parfum (EDP), and Extrait de Parfum. They aren't just marketing labels — each one describes a genuinely different formula, and understanding the difference will change how you shop for fragrance for good.
What Do These Terms Actually Mean?
Every perfume is a blend of aromatic oils dissolved in alcohol (and sometimes water). The percentage of those aromatic oils — called the "concentration" — determines how strong the scent is, how long it lasts, and often, how much the bottle costs.
Eau de Toilette (EDT)
Eau de Toilette typically contains around 5–15% aromatic oils. It's light, fresh, and ideal for daytime or warm-weather wear, but it tends to fade within 2–4 hours and usually needs reapplication.
Eau de Parfum (EDP)
Eau de Parfum sits in the 15–20% concentration range. It's noticeably stronger and longer-lasting than EDT — usually 4–6 hours of wear — and is the most common format sold by mainstream designer brands.
Extrait de Parfum (Parfum / Perfume Extract)
Extrait de Parfum is the most concentrated form of fragrance available, typically containing 20–40% aromatic oils. Because there's less alcohol and more actual perfume oil in every spray, an extrait:
- Lasts significantly longer — often 8+ hours on skin
- Projects a richer, deeper version of the scent
- Needs fewer sprays to achieve full coverage
- Is generally gentler on sensitive skin due to lower alcohol content
This is the concentration used across every fragrance in the Obsidian Fragranza collection — we build every scent as an extrait de parfum from the start rather than diluting it down to a lighter EDT or EDP.
Side-by-Side Comparison
| Type | Oil Concentration | Typical Longevity | Best For |
|---|---|---|---|
| Eau de Toilette (EDT) | 5–15% | 2–4 hours | Daytime, casual, warm weather |
| Eau de Parfum (EDP) | 15–20% | 4–6 hours | Everyday wear, office, versatile occasions |
| Extrait de Parfum | 20–40% | 8+ hours | Signature scents, evenings, special occasions, all-day wear |
Why Obsidian Fragranza Only Makes Extrait de Parfum
We built Obsidian Fragranza around a simple belief: a signature scent shouldn't need to be reapplied to be remembered. By formulating every fragrance as an extrait de parfum from the start — rather than offering a lighter, cheaper EDT version — we're able to deliver the depth, richness, and all-day performance that a true luxury fragrance should have.
Which One Should You Choose?
If you want a light, easy scent for the gym or a quick errand, an EDT-strength fragrance is usually enough. But if you want a fragrance that becomes part of how people remember you — one spray in the morning that's still noticeable at dinner — an extrait de parfum is the concentration to look for.
