What Is EDP?
Eau de Parfum &
Fragrance Types, Explained.
Everything you need to know about fragrance concentration — why it matters, what the types are, and why ATUM builds every perfume as a fine EDP.
EDP — Eau de Parfum — is a fragrance formulated at 15%–20% pure fragrance oil concentration, lasting 6–8 hours on skin. It is the most popular fine fragrance format in the world: richer and longer-lasting than Eau de Toilette, more accessible than Parfum. Every ATUM fragrance is a 50ml EDP, hand-poured at an 80/20 alcohol-to-perfume ratio.
Fragrance comes with its own language — EDP, EDT, Parfum, Extrait — and if you have ever stood in front of a bottle wondering what any of it actually means, you are not alone. These terms describe fragrance concentration: the percentage of pure perfume oil dissolved in a base of alcohol and water. That number controls almost everything — how long a scent lasts on skin, how boldly it projects, how much it costs, and how it develops over time.
At ATUM Fine Fragrance, we have made a deliberate choice to formulate every scent in the collection as an EDP. This guide explains why — and what the difference between fragrance types actually means for your skin.
The Fragrance Concentration
Spectrum
All fragrance is, at its core, a mixture of perfume oil and carrier — typically alcohol, sometimes water. The ratio of oil to carrier determines the concentration type. Here is how each one compares:
Concentration Guide
| Type | Oil % | Wear Time | Character |
|---|---|---|---|
| Parfum / Extrait | 20–40% | 10–14+ hrs | Richest, most intense, most expensive |
| EDP — Eau de Parfum ATUM | 15–20% | 6–8 hrs | Rich, evolving, long-lasting. The fine fragrance standard. |
| EDT — Eau de Toilette | 5–15% | 3–5 hrs | Lighter, fresher. Needs reapplication. |
| EDC — Eau de Cologne | 2–4% | 2–3 hrs | Subtle, casual, close to skin |
| Eau Fraîche | 1–3% | 1–2 hrs | Very light, mostly water base |
What Is EDP — Eau de Parfum?
EDP is the sweet spot. A concentration of 15–20% fragrance oil gives a perfume enough richness to project confidently, enough complexity to develop across top, heart, and base notes over time, and enough oil content to stay on skin through a full day without reapplication. It is the format chosen by most serious niche and independent fragrance houses — because it is where fine fragrance performs its best.
The term Eau de Parfum is French — literally, "water of perfume." Despite the word "water," the carrier is primarily alcohol, which serves as both a solvent for the fragrance oils and a vehicle for projection. The water element is small but plays a role in how the fragrance blooms on skin in the first few moments after application.
"Fragrance is more than something you wear — it is something you experience, collect, and carry with you."

Fragrance Standard
Longevity and projection. A well-formulated EDP lasts 6–8 hours on skin — nearly twice the wear of an EDT — and projects with genuine presence. A scent trail that exists in the air around you, not just against the skin. One application in the morning carries through an entire day.
Complexity and development. Higher oil concentration means more fragrance material available to unfold over time. Top notes open, the heart reveals itself, the base settles — a full narrative arc across hours, not just a single impression on first spray. This is where fine fragrance distinguishes itself from lighter formats.
True cost per wear. An EDP costs more per bottle than an EDT, but 2–3 sprays lasts all day without reapplication — and carries more complex raw materials, heavier musks, richer resins, denser woods than lighter concentrations allow. Fewer applications, less product used, more fragrance experienced. That is where genuine fine fragrance artistry lives.
How a Fine EDP
Unfolds on Skin
Every EDP is built in three layers — a compositional architecture called the fragrance pyramid. The layers are designed to evaporate at different rates, creating a scent that changes and deepens across the hours you wear it.
Citrus, light fruits, green herbs. The most volatile molecules — vivid, immediate, and brief. The first impression of a fragrance: what you smell in the bottle and in the first 15–30 minutes on skin.
Florals, spice, green accords, resins. As the top notes lift off, the heart emerges — the true character of the fragrance. This is where a perfume reveals its personality and where most people fall in love with a scent.
Woods, musks, amber, sandalwood, vetiver, patchouli. Slow to evaporate and deeply persistent — these molecules anchor the fragrance to skin and give an EDP its staying power. The part of a scent still present hours after application.
EDPs carry more heart and base note material than lighter concentration formats — which is why they develop so richly, and why they last. The base is where fine fragrance artistry is most visible.
EDP vs. EDT — What Is
the Real Difference?
EDP vs. EDT is one of the most searched questions in the fragrance world — and the answer matters more than most people expect when they are standing at a fragrance counter.
An Eau de Toilette (EDT) contains 5–15% fragrance oil. It is lighter, fresher, and fades faster — lasting 3–5 hours before it begins to disappear from skin. EDT is a legitimate choice for daytime, warm weather, and situations where a subtle presence is preferable. The format has genuine virtues. But it is not fine fragrance in the same sense — it cannot carry the complexity, depth, or longevity of an EDP.
An Eau de Parfum (EDP) at 15–20% oil does not just last longer. It smells more. More nuance. More evolution. More of the fragrance's actual raw material, developed across hours on skin rather than hours in a bottle. For anyone who wants to wear a perfume rather than apply one, the EDP is the format of choice.
ATUM's position: Every fragrance in the collection is formulated as a 50ml EDP at an 80% alcohol / 20% perfume ratio — not because it is the industry convention, but because it is where these particular fragrances perform best. The notes we use — vetiver, patchouli, oakmoss, sandalwood, birch, amber, incense — require concentration to express themselves fully.

The Travel Sprays
Every ATUM EDP is available as a travel spray — the same fine fragrance formulation in a portable, bag-ready format. Same oil concentration. Same quality. Designed for reapplication throughout the day, for travel, or as a way to carry multiple ATUM scents at once.
EDP travel sprays are among the most practical ways to wear fine fragrance daily. At the same concentration as the full bottle, a travel spray gives you the same wear time and projection — just in a form that fits in a coat pocket or carry-on.
EDP stands for Eau de Parfum — a French term meaning "water of perfume." It describes a fragrance with 15%–20% pure fragrance oil concentration, mixed in a base of alcohol and water. EDP is the most popular fine fragrance format in the world: richer and longer-lasting than Eau de Toilette, more accessible than Parfum. It typically lasts 6–8 hours on skin and develops through distinct top, heart, and base note phases. Every ATUM fragrance is formulated as a 50ml EDP at an 80/20 alcohol-to-perfume ratio.
The difference between fragrance types is concentration — the percentage of pure fragrance oil in the formula:
Parfum / Extrait — 20–40% oil. Lasts 10–14+ hours. Most intense and most expensive.
EDP (Eau de Parfum) — 15–20% oil. Lasts 6–8 hours. The fine fragrance standard: rich, evolving, long-lasting.
EDT (Eau de Toilette) — 5–15% oil. Lasts 3–5 hours. Lighter, fresher, less expensive.
EDC (Eau de Cologne) — 2–4% oil. Lasts 2–3 hours. Subtle, casual.
Eau Fraîche — 1–3% oil. Lasts 1–2 hours. Very light, mostly water base.
For all-day wear, full fragrance development, and the best balance of quality and value, EDP is the preferred choice for fine fragrance.
A quality EDP lasts 6–8 hours on skin. Fragrances with heavier base notes — sandalwood, vetiver, patchouli, amber, musk, and resins — tend to wear toward the longer end of that range. ATUM EDPs such as Fire, Earth, and Offerings are built with rich base note structures and are among the longest-wearing in the collection. To maximize EDP longevity, apply to pulse points on moisturized skin and allow to dry naturally without rubbing.
For fine fragrance purposes — complexity, longevity, and full development of top, heart, and base notes — yes, EDP is the superior format. An EDP lasts nearly twice as long as an EDT, projects more confidently, and carries more of the fragrance's raw material to skin. EDT has its place: for very light daytime wear, warm climates, and anyone who wants a whisper rather than a statement. But if you are investing in a fragrance you will wear as a signature, the EDP is built for that purpose.
