Definition
The term eau de toilette dates to eighteenth-century France, derived from eau de toilette meaning water used at the dressing table. It became the standard descriptor for moderately concentrated fragrance waters by the early twentieth century.
The distinction between EDT and EDP in practice is more nuanced than the concentration table suggests: formula design, natural content, and application method all modulate actual longevity independently of the concentration percentage.
How it works
The EDT has historically been the dominant concentration for mainstream fragrance and many classic niche releases. Its alcohol-to-concentrate ratio allows a lively opening with brighter top notes than an EDP of the same formula, while providing 3 to 6 hours of typical wear. The higher alcohol proportion gives EDT a distinctly different skin feel from EDP or parfum (Wikipedia EN, Perfume, accessed 2026-05-27).
In niche perfumery, the EDT format has been used for deliberate artistic choices: Hermès's Eau d'Orange Verte is a classic cologne-EDT hybrid built for freshness over sillage; Diptyque's early releases were EDTs that emphasized immediacy over longevity. Some houses specifically design EDT versions of their core EDPs to offer a lighter daytime interpretation (Fragrantica, Bois de Jasmin, accessed 2026-05-27).
