Possessing a uniquely diffusive and elegant character, the molecule Ambroxan® (Kao) is a cornerstone of the modern amber olfactive family. Its profile is a masterful interpretation of the finest aspects of ambergris, presenting a warm, sweet, and distinctly dry woody scent. This primary structure is enhanced by sophisticated nuances of cedarwood, a clean pine-like freshness, and subtle, intriguing facets of tea and labdanum. Historically developed from sclareol, a component of clary sage, to provide a stable and ethical alternative to the animalic tincture, its most prized olfactive properties are delivered by its (-)-isomer, which ensures a clean, non-animalic yet deeply sensual warmth.
Valued for exceptional substantivity and a radiant sillage, this material imparts a velvety smoothness and incredible longevity to a composition. In fragrance formulation, recommended usage levels can range from a subtle 0.1% to 2% to act as a powerful fixative, or it can be dosed much higher to form the central theme of a scent. Ambroxan® (Kao) excels at amplifying top notes and providing a seamless transition into the heart and base of a perfume. It combines harmoniously with citrus, florals, musks, and especially other woody notes like vetiver and patchouli, lending a sophisticated, skin-like effect that elevates the entire creation.
