Damascone-Alpha® is an important perfumery ingredient used to build rose, tuberose, amber and spicy notes in fragrances. It brings green, spicy and fruity dimensions to floral compositions, enriching fragrance complexity. Due to its high potency, it is typically used in diluted form.
The history of the ingredient begins in 1965, when chemists P. Ruzicka and Dr. Demole discovered the first rose ketones while analyzing Damask Rose Absolute. This discovery paved the way for synthesizing a category of molecules that would play a decisive role in the fragrance industry.
Compared to Damascone-Beta®, Damascone-Alpha® features a more powerful and earthy profile, whereas Damascone-Beta® offers more fruity and sweet notes.
The 1965 discovery of rose ketones fundamentally changed the world of perfumery, allowing creators to accurately replicate complex rose notes without relying exclusively on natural oils.
Damascone-Alpha® is such a potent ingredient that it is typically used in dilutions of a few parts per million (ppm), meaning a single drop can influence an entire fragrance composition.
The name "Damascone" comes from Damascus roses, a variety cultivated for centuries and renowned for its rich and complex scent.
