Eau de Toilette: This is lighter still and usually sold in spray bottles. The lightness of it makes it more suitable to spray more liberally, the high alcohol content means it will not last very long. Generally this version is the most advisable to use day to day as it is less intense and even if you do use too much it will lighten up fairly quickly. Typically there will be 4-15% pure perfume essence.
