Each perfume is classified according to the concentration of essences or aromatic oils they contain.

Let us demystify this!  

Eau de Cologne :  

Tends to be 7% essence dissolved in alcohol of 60° or 70°. The least concentrated of all. Great for hot weather and tend to be marketed in large sizes up to 200 ml and if often applied by spray. 

Eau de Toilette : 

One of the most popular forms in which fragrances are sold. Patricularly appropriate for the summer, Eau de Toilette evaporates and fades away slowly. It contains up to around 10% aromatic essence. The top notes are dominant. 

Eau de Parfum :  

The concentration of oils is over 15% sometimes reaching as high as 20%. It is less intense than perfume extract, but lasts well and is sold in various sizes. The middle notes or heart notes of an Eau de Parfum is noticeable. 

Parfum : 

The most expensive version of any fragrance, this perfume extract has a high concentration of essence – as much as 40% by volume. It is directly applied to the wrist, behind the ears, and at the throat. It is the longest lasting of all scent categories.
