You've probably seen "EDT", "EDP" or "Extrait" written on a perfume bottle. These abbreviations indicate not the brand but the concentration of the scent — that is, the proportion of essence it contains. The same scent offers a completely different longevity and character at different concentrations. Knowing this difference is the most practical way to choose the right product.
What is concentration?
A perfume consists of essence (fragrance oils) and the alcohol-water mixture that carries it. Concentration is the percentage of pure essence in the total content. The higher the percentage, the more intense and long-lasting the scent; however, its opening is heavier and it projects more closely to the skin.
Types of concentration
The main types, from lowest to highest:
- Eau de Cologne (EDC): ~2–5% essence. Very fresh, short-lived (1–2 hours). Ideal for a quick refresh.
- Eau de Toilette (EDT): ~5–15% essence. Light and everyday; lasts about 3–5 hours on average.
- Eau de Parfum (EDP): ~15–20% essence. Balanced intensity and good longevity (5–8 hours). The most popular type.
- Extrait de Parfum (perfume extract): ~20–30% essence. The most intense and long-lasting form; a little goes a long way and it lasts all day.
Percentages can vary from brand to brand; these ranges offer a general framework.
Which one, and when?
The choice depends entirely on how you intend to use it:
- Daytime, the office, summer: an EDT or a light EDP — a fresh signature without being overpowering.
- Evening, special occasions, winter: an EDP or Extrait — intense, long-lasting and striking.
- A scent that won't disturb those close by: a lower concentration projects less and is more personal.
We gathered the other factors that determine longevity (skin type, scent family, application) in our article on how to choose a long-lasting perfume.
A higher concentration doesn't always mean "better"; it means the right intensity for the right moment.
A common misconception
The idea that "Extrait is always the best" is common but misleading. Wearing an intense extract on a hot summer's day or in an enclosed office can be overwhelming. The goal is to carry the scent at an intensity suited to the setting and the moment. A good wardrobe keeps several options at different concentrations side by side.
In short, the difference between EDT and Extrait is not one of quality but of character and duration. Identify your need, and the right concentration lets you wear your scent exactly the way you want.
