Descriptions
Comment (FraterWork)
In 2024 Firmenich announced the discontinuation of their acclaimed Hyraceum
Absolute 60% DIPG. In 2025 Fraterworks began manufacturing its replacement in
Grasse. We are now the only supplier of this wonderful natural musk absolute.
Hyraceum Absolute opens with fierce animalic intensity—phenolic, urinous notes
mingle with tarry leather and scorched earth. This fossilised essence captures
millennia of African sun and stone. Use it where you need uncompromising
animalic depth without ethical compromise.
This material transforms on warm skin from challenging rawness to seductive
warmth. Build leather accords with unprecedented realism or add subliminal
sensuality to florals. Master perfumers reach for Hyraceum when synthetic musks
lack soul and natural alternatives prove too tame.
Dose carefully—traces add mysterious depth whilst higher amounts create bold
animalic statements. Combine with labdanum for rich leather effects or blend
into oud reconstructions for authenticity. In chypres, it provides the dark
foundation modern regulations have diminished in their restriction on oakmoss.
WHAT IS HYRACEUM?
Hyraceum comes from the fossilised urine and faeces of the Rock Hyrax (Procavia
capensis), a small mammal native to Africa and the Middle East. These
rabbit-sized creatures live in colonies and use communal latrines in protected
rock crevices over many generations.
The hyrax produces unusually viscous, jelly-like urine that's exceptionally rich
in calcium carbonate and other minerals. When deposited repeatedly in the same
sheltered spots by entire colonies, this material dries, hardens and petrifies
over centuries. Some deposits are over 50,000 years old.
Collection involves mining these ancient, fossilised middens - the rock-like
masses that have accumulated in caves and crevices. The material is literally
chipped away with hammers and chisels, as it's extremely hard and dense.
Collectors harvest only from abandoned sites where no living hyrax colonies are
present.
The raw "Africa Stone" is then either extracted with solvents to produce an
absolute (like the discontinued Firmenich product) or macerated in alcohol to
create tinctures [https://fraterworks.com/products/hyraceum-tincture-10]. The
Fraterworks Signature Absolute undergoes extraction in Grasse using traditional
methods to capture the complex aromatic compounds that develop during the
millennia-long ageing process.
Interestingly, the Rock Hyrax's closest living relatives are elephants and
manatees - they shared a common ancestor 60 million years ago. Despite looking
like oversized guinea pigs, they have continuously growing tusk-like incisors
similar to elephants.
ODD NAMING CONVENTION
Note that this absolute is diluted in DPG to make it fluid. Firmenich's version
of this material was called Hyraceum Absolute 60% DIPG which normally means 60%
hyraceum absolute and 40% DPG, but for some reason they did the opposite, and it
was 40% hyraceum and 60% DPG. For the sake of continuity and discovery we have
followed that same inversion of the perfumery convention here and so this
product is called Hyraceum “Signature” Absolute 60% DPG but contains 40%
hyraceum absolute and 60% DPG.
