Ambronova

Ambronova is a novelty that the fine fragrance division of a fragrance house presented at the World Perfumery Congress in 2024. It was shown in the division's own exhibition suite, where the new Iconoclast series and Frostwood made their debut as well.

Composition and chemistry

The same paper presents two novel methoxy ketones that can be obtained in pure form by Claisen chemistry from β-cedren-9α-ol and methoxy acetone. Their highly potent dry-woody ambergris notes show that a ketal function is not a prerequisite for a dry woody ambergris odorant.

Launch

The World Perfumery Congress 2024 took place from June 24 to 27 at the Palexpo site in Geneva, Switzerland. Its theme that year was "Fragrance Forward: Where Global Innovation & Creativity Meet". The fair is one of the most important platforms for fragrance ingredients and draws management, perfumers and purchasing professionals from around the world. Team members also took part in panel discussions during the congress, among them one on the role of artificial intelligence in perfumery. Another conference, "Perfumers and Research: 150 Years of Vanillin", was to focus on discoveries made in a laboratory in Holzminden.

Background: how new fragrance ingredients are protected

A captive is an aroma chemical kept by the manufacturer that invented it for exclusive use in its own perfumes, to protect them from imitation. Perfume formulations cannot be patented, but new odorants can be, so a patented compound can be produced only by the patent owner.
