Terms such as “eau de toilette” and “eau de parfum” refer to the concentration of perfume oil in the fragrance. The higher the concentration, the more intense and long-lasting the scent is, generally speaking.

Perfumes listed as “parfum” or “extrait” have the highest amount of perfume oil (about 25% or higher). Eau de parfum is the next highest (15-18%), followed by eau de toilette (around 10%), eau de cologne (around 5%), and at the lowest concentration, body spray and after-shave (1-3%).
