Eau-de-Cologne (EDC) is a type of fragrance with a low concentration of perfume oils, usually around 2–5%, mixed with alcohol and water. Because of this lighter concentration, it smells fresh and refreshing but typically lasts only 2–3 hours on the skin.
Eau-de-Cologne often features citrus, herbal, and light aromatic notes, making it a popular choice for daily wear and warm weather. Compared to stronger fragrances like Eau de Parfum, cologne is lighter and less intense.
