About this material
Cedryl Acetate by IFF is a powerful fixative with a tenacious, dry, woody, cedar scent and a subtle leathery quality.
Supplied here in the form of white/translucent crystals. It is far more superior than the liquid Cedryl Acetate by Givaudan
It has a woody, slightly leathery aroma with an earthy undertone, similar to Vetiver Acetate.
Cedryl Acetate Crystals are a great choice for adding a consistent woody note to a fragrance without the distinctive character of a woody essential oil like Virginian or Atlas Cedar oil.
It also lacks the terpenic top note that can be found in some woody essential oils.
By complementing other woody materials, it enhances and prolongs the woody scent without overpowering it.
Additionally, it can be used to add a subtle woody background to fragrances where a dominant woody note is not desired.
In citrus, herbal, and spicy formulations, it performs exceptionally well.
It is a great addition to candle fragrances when combined with vertenex, as it provides a woody note without causing wick-clogging issues that some resinous essential oils may have.
The typical usage range for this product in fragrance formulas is between 1% and 10%.

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.
