Understanding fragrance concentrations
What common fragrance labels can—and cannot—tell you.
Terms such as Eau de Toilette and Eau de Parfum can help you compare fragrances, but they are general descriptors rather than universally fixed international definitions.
Common industry ranges
The International Fragrance Association lists typical ranges for ethanol-based fragrances: Eau de Cologne about 3–8%, Eau de Toilette about 5–15%, Eau de Parfum about 10–20%, and perfume extract about 15–40%. These ranges describe common practice, not strict guarantees.
Concentration is not the whole experience
Longevity and projection also depend on the materials used, the structure of the formula, climate, application and individual skin. A higher concentration may not always feel stronger at every stage.
Choose by wearing, not by label alone
- Test on skin when possible and allow the fragrance to develop.
- Compare after several hours, not only in the first minute.
- Follow product directions and avoid eyes, irritated skin and open flame.
- Buy through brands or authorized sellers when authenticity matters.
NOUR will describe concentration as one part of the fragrance story, alongside notes, character, wear and authenticity.
