Concentration

nounFormats

The proportion of fragrance concentrate in a finished perfume product.

Also known as: fragrance concentration, perfume concentration

In simple terms

A perfume blends its scented concentrate with a carrier or delivery system. Concentration describes the proportion of that concentrate, not how many notes the perfume has. Bottle labels can offer a broad cue, but usually do not disclose an exact percentage.

How concentration works

The names eau de toilette, eau de parfum and extrait are used for different product formats and concentration conventions. Houses may also change the composition between versions. Compare the actual products, rather than assuming the same formula has only been diluted differently.

Examples

An EDT and an EDP sharing a name can emphasise different facets as well as having different concentrations.

“I prefer the EDT’s brighter character, even though the EDP is the more concentrated format.”

Illustrative example

Common misunderstandings

A common misunderstanding

Higher concentration does not by itself guarantee greater projection, longer wear, better quality or a closer match to your taste.
