The difference between perfume and cologne depends on who is speaking. In perfumery, eau de cologne is a strength: the lightest traditional concentration, often around 2–5 percent perfume concentrate, usually fresh and citrus-led, and short-lived. In everyday speech, especially in the United States, cologne is often used for any fragrance marketed to men, and perfume for any fragrance marketed to women — whatever their actual strength. Neither use says who may wear it.
This article untangles the two meanings and explains what to look for on a label.
Meaning one: a concentration
Fragrances are sold at different strengths, described by French terms on the bottle. From lightest to richest, the common ones are:
- Eau de cologne — very light, often a few percent; fresh, quick to fade.
- Eau de toilette — light to moderate.
- Eau de parfum — richer and usually longer-lasting.
- Parfum or extrait de parfum — the most concentrated.
The figures vary between houses, so treat any percentage as approximate. Each strength is explained in Perfume Concentrations Explained.
In this sense, "perfume" can mean either the general category — all of these are perfumes — or specifically the most concentrated strength, parfum. That double meaning adds to the confusion.
Meaning two: a fragrance for men
In American English, and increasingly elsewhere, "cologne" is commonly used for men’s fragrances and "perfume" for women’s. A bottle sold to men as "cologne" may in fact be an eau de toilette or an eau de parfum, and may last as long as anything sold as "perfume".
This usage is a matter of marketing and habit, not of smell. Plenty of fragrances sold to women are fresh and citrus-led; plenty sold to men are sweet, floral or rich. See What Makes a Fragrance Unisex?.
"Cologne" on a shop sign tells you who it was marketed to. "Eau de cologne" on a bottle tells you how it was made.
Where the word came from
Eau de Cologne — "water of Cologne" — was the name of a light citrus-and-herb water sold in the German city of Cologne in the early eighteenth century by Italian perfumers living there. It became so famous that its name became a generic term, first for that style of fragrance and later, in some countries, for fragrance in general. The full story is in The History of Eau de Cologne.
The classic eau de Cologne was worn by men and women alike, and it was splashed on generously. The gendered meaning came much later.
How to read a label
If you want to know what you are buying:
- Look for the strength in the small print — eau de toilette, eau de parfum, parfum — rather than the word on the shop sign.
- Read the notes and family, which tell you the style. A fresh citrus "cologne" and a warm amber "cologne" have little in common.
- Smell it on skin. See How to Test a Perfume Before You Buy It.
Which lasts longer?
A true eau de cologne is usually the shortest-lived strength, often noticeable for an hour or two, because it is light and built on volatile citrus materials. A fragrance merely called cologne may last as long as any other eau de toilette or eau de parfum. For what affects lasting power, see How to Make Perfume Last Longer.
Common questions
Can women wear cologne, and men wear perfume?
Yes. Smell has no gender, and people of every gender wear fragrances from both sides of the shop.
Is cologne weaker than perfume?
A true eau de cologne is weaker than eau de parfum or parfum. A men’s fragrance called "cologne" in conversation may not be.
What is the difference between cologne and aftershave?
Aftershaves and aftershave balms are usually lighter still and may contain ingredients intended to soothe skin after shaving. Like cologne, the word is used loosely.
Is "eau de cologne" the same as "Kölnisch Wasser"?
Kölnisch Wasser is the German name for eau de Cologne — the same "water of Cologne".
