Eau de cologne, or water of cologne, is an alcohol based perfume. It can be used by men or women and is the kind of perfume most often chosen for day time wear because it is light in fragrance. The alcohol base makes it evaporate quickly into the air. It does not have the long lingering fragrance of more concentrated perfumes that are great for night time wear but a bit over powering for the office.
