EDP, EDT, Parfum: What's Actually in Your Bottle?

Every fragrance bottle carries a small, cryptic label: EDP, EDT, parfum, cologne. Most shoppers nod at the letters and quietly hope for the best. But those letters are the single most useful thing on the box — they tell you how strong the scent is, roughly how long it will last, and a good part of why it costs what it costs. Once you can read them, you stop guessing and start choosing. Here is the whole system, explained the way we explain it across the counter.

It comes down to concentration

A finished fragrance is perfume oil diluted in alcohol. The label tells you the proportion of oil in the mix. At the top sits parfum — sometimes called extrait — at roughly 20 to 30 percent oil or more. Below it, eau de parfum (EDP) usually runs 15 to 20 percent. Eau de toilette (EDT) lands around 5 to 15 percent, eau de cologne (EDC) at 2 to 5 percent, and body mists below that. The exact numbers vary by house, but the ladder is universal: more oil, more intensity, and — generally — more time on the skin.

Concentration is not a quality ladder

Here is the part the marketing leaves out: a higher percentage is not a better perfume, it is a different behaviour. A rich parfum sits close to the skin, deep and dense, unfolding slowly like a low voice. An eau de toilette is built brighter — more lift, more sparkle, more of that fresh opening — precisely because the lighter dilution lets the citrus and green notes fly. Plenty of beloved classics are EDTs by design, not by budget. Choosing between them is choosing a style of presence, not climbing a ladder from worst to best.

EDP is not the upgrade of EDT. They are two dialects of the same language.

Why the price climbs with the percentage

Perfume oil is the expensive ingredient; alcohol is cheap. Double the oil in the bottle and you have, roughly, doubled the cost of what is inside it — before you count rarer raw materials that concentrated formulas often carry. That is why a small bottle of parfum can cost more than a big bottle of eau de toilette from the same line. It is also why comparing bottles by size alone misleads: a 30ml eau de parfum may deliver more actual fragrance than a 100ml eau de toilette, because each spray carries more of the good stuff.

Longevity versus projection: pick your trade-off

In practice, concentration trades projection for longevity. Lighter formulas announce themselves — the scent reaches across the desk in the first hour, then softens. Heavier formulas stay closer but endure, greeting you from your collar long after lunch. Season plays a role too: in a Toronto July, a heavy parfum can feel like a wool coat, while a bright EDT is a linen shirt; in January, that same EDT may seem to evaporate into the cold, dry air. Many collectors quietly keep both — an EDT for summer days, an EDP for evenings and winter.

So what should you buy?

Match the label to the job. For daily wear that lasts a full workday without overwhelming a shared office, eau de parfum is the dependable middle: strong enough to stay, composed enough to sit politely. It is why most of what we carry — from the 100ml bottles to our pen perfumes — is eau de parfum. Reach for an eau de toilette when freshness and lift are the whole point: mornings, gym bags, summer. Save true parfum for when you want depth that stays close and personal. Read the letters first, and the bottle will rarely surprise you.
