Eau de Parfum vs Eau de Toilette vs Extrait: What Perfume Concentrations Actually Mean

If you have ever stood in front of a shelf wondering why the same name comes in "eau de toilette," "eau de parfum," and "extrait" — and why the prices jump — this is for you.

These words describe perfume concentration: how much actual fragrance is in the bottle versus how much alcohol and water. In this article we will explain what each term means, the rough percentage ranges behind them, and one fact that surprises most people: none of these labels are defined by law.

What does perfume concentration actually mean?

A perfume is mostly two things: aromatic compounds (the "juice" — the oils and molecules that you smell) and a carrier, almost always alcohol with a little water.

Concentration is the percentage of aromatic compounds in that mixture. A higher concentration generally means a richer, longer-lasting scent that sits closer and develops more slowly. A lower concentration is lighter, fresher, and tends to fade faster.

That is the whole idea. The familiar French names are simply a shorthand the industry uses to signal roughly where a fragrance sits on that scale.

The main concentration types, explained

From strongest to lightest, here are the categories you will see, with the concentration ranges most commonly cited across the industry:

• Extrait de Parfum (also called parfum or pure perfume): roughly 20–40%. The richest and longest-lasting, usually worn sparingly.
• Eau de Parfum (EDP): roughly 15–20%. The modern default for fine fragrance — depth and longevity without feeling heavy.
• Eau de Toilette (EDT): roughly 5–15%. Lighter and fresher, often the brighter, more casual version of a scent.
• Eau de Cologne (EDC): roughly 2–5%. Light and short-lived, traditionally citrus-forward and splashed on generously.
• Eau Fraîche: roughly 1–3%. The lightest of all, mostly water-based, for a brief, subtle freshness.

The thing most people don't know: there is no legal standard

Here is the part that catches people off guard. These terms are conventions, not regulations. There is no international law that says an eau de parfum must contain a specific percentage of oil.

In practice, each house decides where its own products land. That has a real consequence: one brand's eau de toilette can be stronger than another brand's eau de parfum. The ranges above overlap, and they are guidelines rather than guarantees. So the label on the box tells you the maker's intention — lighter or richer — but it does not, on its own, tell you exactly how a fragrance will perform on your skin.

Does a higher concentration mean a better perfume?

No. This is the most common misunderstanding, and it is worth saying plainly.

Concentration changes a fragrance's character — how it projects, how long it lasts, how close it stays to the skin. It does not measure quality. A thoughtfully built eau de toilette made with excellent materials can easily outclass a cheap extrait that simply has more oil in it. What matters far more than the percentage is the quality of the raw materials, the skill of the formula, and how the finished perfume has been allowed to mature.

In other words: concentration is a dial, not a grade.

How we think about concentration at SHŌ ITO

We release our fragrance as an extrait de parfum — around 25% — in a 50ml bottle. That choice was deliberate.

Extrait strength gives the materials real depth and stay-power, so the heart and base carry through a day rather than fading by lunchtime. But concentration is not the same as projection: a higher percentage gives us more to work with, not a louder scent — we compose for depth that stays close to the skin. That suits how we want our perfume to be worn — as something intimate, noticed by people who lean in, not announced across a space.

Just as importantly, we do not treat the concentration number as the headline. We would rather spend our effort on the things the label cannot show you: the quality of the materials we choose, and the time we give the finished blend to rest and settle before it is bottled. A higher percentage on the box is easy to print. A well-made perfume is not.

The short version

• Concentration is the share of aromatic compounds in a perfume, with the rest being alcohol and water.
• From richest to lightest: extrait, eau de parfum, eau de toilette, eau de cologne, eau fraîche.
• The percentage ranges are industry conventions — there is no legal standard, and they overlap.
• Higher concentration changes character and longevity, not quality.
