Sillage and durability
Buying a perfume only to find out later that it doesn't last long can be really frustrating. But, how can you avoid (un)pleasant surprise ?
When talking about how long a perfume lasts, the two most frequently used terminology are : durability and sillage – two concepts closely link with volatily and the molecules concentration composing the perfume.
The sillage is the trace we left behind when you move from one room to another, for example. A sillage will be subtle for perfume smelled next to where it was misted whereas, a perfume will have a intense sillage if it's discernible at a greater distance from where it was sprayed or long after you were there.
If you want to wear a perfume at work, in an open-space, choose a product with a more subtle sillage and be careful to not overmist it. On the contrary, if you want a long-lasting sillage in an evening event, an intense sillage is recommended.
The durability of a fragrance is measured by the number of hours a fragrance persists from the perception of the wearer. For a Hedisperian perfume (mostly citrus notes ), durability tends to be lower than with a perfume with woody or spicy notes.
Unlike some claims, an Eau de Parfum or a perfume extract does not assure a longer sillage – it could hardly have been otherwise - The more a perfume is diluted in alcohol, the faster it diffuses. This is justified by the fact that alcohol quickly evaporates, dragging the perfume molecules with it. A perfume extract, highly concentrated in fragrant substance, contains less alcohol, so, its fragant molecules will stay closer to your skin with a better durability.
