About this material
Elevate your fragrance compositions with the discreet power of Fixateur 505E — a masterfully engineered base designed to enhance longevity, depth, and olfactory cohesion.
Crafted by Firmenich, one of the world’s most revered fragrance houses, this fixative embodies precision, subtlety, and performance at the highest level.
Fixateur 505E works behind the scenes, anchoring volatile top notes while enriching the diffusion of heart and base accords.
Its neutral yet sophisticated profile ensures it harmonises effortlessly with both delicate florals and rich oriental blends, extending wear time without altering the intended character of the perfume.
While it may appear understated at first — particularly in its undiluted form — Fixateur 505E reveals its true character once blended into a composition.
It brings to life a powerful, remarkably lifelike interpretation of natural ambergris, complete with its nuanced animalic signature — a depth notably absent in materials such as Ambroxan.
The result is a dry, woody, earthy ambergris profile of exceptional strength and sophistication, underpinned by an extraordinarily tenacious odour trail.
An iconic base material, Fixateur 505E traces its heritage to Firmenich’s original showcase for the then-captive AMBROX® DL.
Historically, several variations existed within the Fixateur range, each formulated to facilitate the use of AMBROX; today, these have been refined and consolidated into the singular, definitive 505E.
This lineage reinforces its status as a cornerstone ingredient in modern perfumery.
Favoured by perfumers seeking refinement and durability, this professional-grade fixative imparts a smooth, lingering trail — allowing compositions to unfold gracefully over time.
Whether used to stabilise intricate formulas or to enhance the overall tenacity of a fragrance, Fixateur 505E is an essential tool in the art of fine perfumery.

Generic reference only — not an IFRA certificate, compliance decision or use recommendation. The Responsible Person and qualified safety assessor must assess the actual finished formula using current applicable IFRA Standards, supplementary documentation where available and the CPSR.
Raw undiluted material reference. These data refer to the named active material, not the complete supplied dilution. A raw-material IFRA ceiling is not a use level for this diluted product. The assessor must account for the actual concentration, carrier and all other formula contributions.

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.

I use this in tandem with Ambroxan and musky note and it adds depth and layers to the blend
