Difference between Eau de Toilette and Eau de Parfum – We speak of perfume in a general way and sometimes wrongly: indeed, an eau de toilette, it is not a perfume! While it smells good, but there are real differences that you may not know. We help you to see more clearly so that you can buy the product that meets your expectations.
Formulation of a perfume
The formulation most used in the perfume industry, and also the most recent in the West because its use dates back to the 14th century, is the one whose support is alcohol. Previously, oily or greasy carriers were used. The perfumes of our days are so-called alcoholic perfumes since the support is alcohol. This is ethyl alcohol because it is a neutral substance, which will not alter the scent of the fragrance concentrate.
Fragrances are composed of three elements: the fragrance concentrate, the support, and the fixer.
In perfumery, ethyl alcohol can dilute the fragrance concentrate. In addition, being very volatile, this alcohol will evaporate quickly to leave room for odorous substances on the skin. It is also he who is responsible for the feeling of freshness felt on the skin after being sprinkled with a scented juice. Indispensable, alcohol allows the perfume to be well preserved in time.
Perfumed juice (or fragrant concentrate) is the term for the oils present in the perfume and which, depending on the dosage, allow a longer or shorter duration of it. And it is on this main difference that the distinction between perfume and eau de toilette is made. It’s all about concentration. The juice is added to alcohol (which is present at a level of 70% minimum). The difference in concentration determines whether it is a perfume or a toilet water.
Depending on the concentration of alcohol, it will be a perfume, an Eau de Parfum, a toilet water or a fresh water.
Difference between “Eau de Parfum” and “Eau de Toilette”
After all this gibberish, here are the different appellations and concentrations:
- The light waters (fresh water, tonic water): contain a maximum of 4% concentrate.
- Colognes (EDC – created in 1709): are dosed from 4% to 6%.
- Toilet waters (EDT): the trail is cooler and light, contain 7 to 12% concentrate. Its smell varies between 3 and 5 hours depending on the mixture and the proportion of ingredients.
- Eau de Parfum (EDP) (much more expensive): reach a concentration of 12 to 25% depending on the manufacturer. Its duration varies between 4 and 6 hours. It volatilizes faster than the perfume. Perfect for everyday use.
- The perfumes: concentrated around 18%. The smell stays on the skin for a long time.
- Extracts: from 20%, we enter the field of extracts, essences or perfume elixir. The concentration rate can reach 40% in the case of the most prestigious perfumes. It is the most concentrated and its price is the highest. His concentration is purer. A few drops on the skin are enough for a refined fragrance.
The more the amount of perfume concentrate or “juice” is important, the longer the holding of the perfume lasts in time.
But there is also another factor to take into account for holding a perfume over time. It is simply the skin on which it is applied or sprayed. There are differences between the skins (oily or dry skins, pH level …), it necessarily plays a big role on the outfit.
