Eau de Toilette diluted, lightly scented perfume, otherwise wrongly known as a cologne, which is primarily used as a skin freshener in perfumery. It features high levels of alcohol, and is often used right after bathing or shaving. In the past, the products labelled as “eau de toilette”, were often accompanied by the name of the main ingredient in the mixture. Various materials have been associated, often even synonymous, with eau de toilette, with most of these substances being flower derived. This has led eau de toilette to be referred to in many English speaking regions as “flower water”. Some examples of mixtures being utilized for eau de toilette colognes including geranium water, lilac water, and violet water.
These days, perfumery usually utilizes the term as a means of showing the general strength of any given mixture, with eau de toilette being the medium strength dilute perfume between eau de cologne and eau de parfum.
Not always, but very often, perfume oils are diluted via a solvent — although this practice is questioned by many for being somewhat unnecessary. The most common solvent used to dilute perfume oil is ethanol, or a solution that includes both ethanol and water. Eau de toilette features the smallest amounts of perfume oil out of any of the other major perfumery categories. It differs from a true cologne, in that it is generally stronger in its aromas, and is not limited to the presence of any specific compounds — able to be made up of much more than just citrus extracts.
Eau de toilette mixtures are most commonly made up of around 10% aromatic compounds, with the remainder being either ethanol, or a mixture of ethanol and water.
