Eau de Parfum, Eau de Toilette: names you have probably seen in the past. But what is the difference between them?
In simple terms, the difference comes from the intensity or concentration of the fragrance. A perfumer sometimes combines more than 100 differently scented ingredients. This “mixture” is called a pure perfume or the perfume oil. In order to determine the right strength of the perfume and to ensure safety on the skin, the pur perfume is mixed with a solvent. Perfumers usually use ethanol for this, but they could also use unscented oil or wax. Alcohol is most commonly used as a solvent and is often mixed with a small amount of water. Alcohol makes the product easy to spray, it evaporates quickly and leaves the fragrant components nicely spread on the skin. Furthermore, alcohol has relatively little scent of its own and gives a cooling refreshing effect.
The difference between Eau de Toilette and Eau de Parfum
Based on the amount of pure perfume, we can determine the name of a perfume. For example, an Eau Fraiche contains the minimum concentration of perfume oil, followed by Eau de Cologne.
Eau de Toilette has been the most common strength for fragrances for years. An Eau de Toilette is nice for everyday use, because this formula is frequently lighter. Depending on the quality and structure of the fragrance, you can still enjoy it for quite some time. On average, an Eau de Toilette contains somewhere in the range of 5 and 10% of perfume oil.
If you choose an Eau de Parfum, you choose a fragrance that is a bit more intense, extravagant and fuller than an Eau de Toilette. As a result, you often enjoy an Eau de Parfum the entire day or even night! Most Eau de Parfums contain on average between 10 and 20% perfume oil.
The main contrast is therefore the amount of pure perfume in the formula: an Eau de Toilette contains less perfume oil and more water and alcohol than an Eau de Parfum. Depending on what you like as far as the intensity of a fragrance, you can choose an Eau de Toilette or Eau de Parfum.
Is there a difference in fragrance with the different formulas?
It is possible that you see both an Eau de Toilette and an Eau de Parfum of a fragrance, and although the formulas could be identical, they only differ in concentration. For example, the perfumer can add more emphasis on the light-footed and transparent character of the fragrance in the Eau de Toilette, while in the Eau de Parfum, the deeper and exotic elements of the fragrance are more exposed.
