Kephalis (Givaudan)

Description

A sophisticated and powerful woody ingredient. Its profile unfolds with a rich, ambery-woody core, recalling the scent of old, polished wood and the subtle sweetness of cured tobacco leaves. An underlying clean, herbal facet adds a distinctive freshness that balances the composition’s inherent richness. The result is a remarkably linear and consistent effect that provides exceptional stability and substantivity. Developed by Givaudan, the ingredient known as Kephalis serves as a key material for building robust and elegant fragrance structures, prized for its complex yet reliable character.

The versatility of this compound allows it to seamlessly integrate into a wide array of fragrance types. It performs as a powerful and long-lasting heart and base note, lending significant volume, structure, and depth to a creation. In floral compositions, Kephalis enhances the sensuality of jasmine, rose, and violet, while providing a modern twist to classic lavender accords. It is a fundamental building block in sophisticated ambery, woody-aldehydic, and masculine fragrances. With a recommended use level from 1% up to 8%, it can add a subtle richness or become a dominant, defining signature in the final perfume.
