Eau de Cologne (French: [o d(ə) kɔlɔɲ]; German: Kölnisch Wasser [ˈkœlnɪʃ ˈvasɐ]; lit. “Water of Cologne”), or simply cologne, is a perfume originating from Cologne, Germany. Originally mixed by Italian-born Johann Maria Farina in 1709, it has since come to be a generic term for scented formulations in typical concentration of 2%–5% and also more depending upon its type essential oils or a blend of extracts, alcohol, and water. In a base of dilute ethanol (70%–90%), eau de cologne contains a mixture of citrus oils including oils of lemon, orange, tangerine, clementine, ****, lime, grapefruit, blood orange, and bitter orange. It can also contain oils of lavender, rosemary, thyme, oregano, petitgrain (orange leaf), jasmine, olive, oleaster, and tobacco.
