Eau de cologne

An eau de cologne (EDC) is a fragrance concentration containing 2 to 5% perfume concentrate in an alcohol-water base, the lightest standard concentration category, traditionally built around citrus-aromatic accords and designed for refreshing wear (Société Française des Parfumeurs EN, accessed 2026-05-27).

Definition

Eau de cologne is simultaneously a concentration category, a style category, and a historical brand name. The legal status of the designation varies: in Germany, Kölnisch Wasser (cologne water) is a registered geographic designation; in international perfumery, it is a generic concentration label.

In contemporary niche perfumery, the cologne category has been revisited with higher-quality naturals and higher concentrations, blurring the line between classic EDC and modern cologne-style fragrances.

How it works

The eau de cologne format originated in Cologne, Germany, with Johann Maria Farina's Eau de Cologne (1709), a light citrus-aromatic formula centered on bergamot, lemon, neroli, and rosemary in high alcohol dilution. The name became generic: by the nineteenth century, eau de cologne referred to any fragrance in this light, fresh, citrus-led format (Wikipedia EN, Eau de cologne, accessed 2026-05-27).

Due to its low concentration, an EDC offers limited longevity (typically 1 to 2 hours) but maximum freshness. It is applied generously and frequently, traditionally poured rather than sprayed. Niche uses: Atelier Cologne built its brand around the cologne absolue format (8-15%), a more concentrated version of the cologne aesthetic. Hermès releases cologne concentrés as higher-dilution takes on the genre (Fragrantica, accessed 2026-05-27).
