About this material
Cedramber is a refined expression of modern perfumery—an elegant, high-impact ingredient prized for its exquisite, enveloping aroma.
Derived from natural inspirations, it reveals a beautifully balanced profile of warm, woody notes, delivering both depth and radiance to fine fragrance compositions and personal care creations alike.
Renowned among perfumers for its versatility, Cedramber offers a sophisticated and cost-effective alternative to synthetic ambergris, imparting a rich, long-lasting sensuality that enhances and anchors complex accords.
Its smooth, ambery-woody character blends seamlessly with complementary materials such as Vertofix, Ambroxan, and Fixateur 505 E, amplifying diffusion and longevity.
Particularly valued as a fixative, it excels in stabilising and elevating delicate floral aldehydic notes.
It harmonises beautifully with ingredients such as Undecylenic Aldehyde, Cyclamen Aldehyde, Lyral, and Lilial, lending structure, warmth, and persistence to luminous floral compositions.
A staple in contemporary fragrance design, Cedramber embodies both luxury and performance—an essential ingredient for perfumers seeking to craft enduring, captivating scents.
Embrace the allure of Cedramber and experience its distinctive, velvety essence today.

Creative ideas to explore
Creative directions, not tested formulas.Woods in daylight
With bergamot and a crisp citrus openingExplore a spare wood structure with citrus providing the opening contrast. Compare a brighter version with the wood reference and follow how the outline changes, keeping the later impression as important as the first moment.
A softer grain
With sandalwood and a musk directionSet the woody material beside a softer wood reference, then compare a restrained musk variation. Decide whether your concept needs creamy texture, dry definition or more space between its parts before expanding the accord.
Petals on timber
With rose and a clear floral accordTry a flower-and-wood study in which both subjects remain recognisable. Compare the floral reference with the woody variation through the evaluation, noting whether the wood forms a useful backdrop or becomes the centre of the idea.






Anis Dadou –
My favourite wood-amber. Very dry woody, without the ‘screechy-ness’ (so called) experienced with modern wood-amber-super-ambers like Ambrocenide. Though not as diffusive or multifaceted as those (which often have background soft vanilla like elements). Cedramber is decidedly dry wood, ambroxan without the sweetness
