hedione: 3 posts

Perfume wearers and boats have more in common than one might reasonably suspect. Sillage (pronounced as see-yazh) is a French word that means “wake”, as in the airplane contrails criss-crossing the skies or the waves left on water by a passing ship. But it’s also used to describe the scented trail created by perfume. Sillage defines the degree to which fragrance emanates from its wearer and diffuses into the space around them.

Sillage is an important quality to keep in mind when buying a perfume or when selecting it for specific occasions. Big sillage scents are the most complimented because they’re easy to notice, but their distinct presence may make them inappropriate for restaurants, theatres, or some office environments. On the other hand, a fragrance that doesn’t bloom at all is rarely satisfying. The goal is to find the right sillage for your mood and lifestyle.

As a counterpart to the first series of Synthetics in Perfumery, here is the second part. The material I cover today is hedione. I explain how and by whom it was discovered, what led up to the experiments with hedione and what makes it such an important material. Hedione, which is the Firmenich tradename for methyl dihydrojasmonate, occurs naturally in jasmine. While its quantity in jasmine essence is quite small, it provides a unique radiant effect–and that is what Edmond Roudnitska discovered when he used it to create Dior’s Eau Sauvage. While on its own hedione doesn’t have a particularly strong character, the luminosity and radiance that it lends to compositions are striking.

Without hedione, Eau Sauvage would have been a well-crafted but not particularly memorable cologne. Without hedione, we wouldn’t be able to experience a variety of sensations and textures. It’s one of the most versatile perfume materials and today it’s hard to find a fragrance that doesn’t include it.

If you’ve liked my video and want to learn more about hedione, here is another article: Hedione Luminous Jasmine. It includes a number of perfume examples and mentions the doses of hedione used in them.

I’ve made a series of videos about synthetics in perfumery–from a perfumer’s perspective. I would like to explain why certain synthetic aroma-materials have become important in modern perfumery and what effects they create. The video I share today is the  first in the series, and it will offer an overview of the topic as well as talk about one of the most important synthetics. The second video will be released next week.

If you have any suggestions on the materials you would like me to cover or specific topics, please let me know. I note down all of your requests. Thank you!
