is sometimes used in the same context as eau de toilette. It was first developed in the early 18th century and made popular by Napoleon. It is a light, fresh citrusy scent, based on citrus, neroli, lemon, bergamot and lavender, intended to be refreshing and airy, but not very long-lasting. Modern eau de colognes contain 3-5% perfume oil and 70% alcohol/water mix.

Originally the name applied to light refreshing Citrus scented fragrance, also see Cologne. Now, more widely used to relate to a solution of about 3% Perfume compound in an alcohol/water base and is much lighter than a concentrated perfume.

Eau de Cologne is the term used today to refer to a perfume solution with around a 3% compound in an oil and water base. It's the lightest of perfumes and, therefore the least expensive.

Eau de Cologne (French for "water of Cologne", Kölnisch Wasser in German) is a type of light perfume that originated in Cologne, Germany and is defined by its typical concentration of about 2-5% essential oils.
