Leather Note in Perfumery

Leather Notes in Perfu mery
Leather.(Notes from Perfu me and Flavor Materials by Steffen Arctander)
The term "leather"-notes or "leather" perfume
types occur quite frequently in the perfumer's
language. There are even a number of different
perfume types which fall under the category of
"leather". Originally and truly, the odor should
only derive from leather, more exactly from
untanned leather. But the use of the term "leather"
for an odor has slowly changed to become a
description of the tanning and processing materials
in respect to odor type. The curing and tanning
of leather involves the use of a number of chem-
icals, and the process is well known for the
obnoxious odor emitted by the wet leather in the
tanning brine. Various phenols are used as
preservatives, but natural tars have also been
used as "masking" odors during the process.
The leather will acquire an odor of such tars and
retain that odor for a very long time. This odor
has become synonymous with "leather" odor.
As a final step away from the original meaning of
the term, also the various chemicals used in the
curing are known as having a "leather" odor.
A true Leather Tincture was produced in
Germany years ago. Waste pieces of "Juchten-
leder" or other cuttings of leather were chopped
and extracted with alcohol by maceration. Such
tinctures are not commercially available.
In France, the "leather" notes are generally
known as "cuir" or "cuir de russie" (Russian
leather), but none of the commercial products
are based upon natural leather. Birch Tar Oil
fractions, Castoreum Tincture, various phenols,
cresols, creosol, isobutylquinoline, cananga oil,
zingerone, anhydrol ethyl labdanate, mate, styrax,
crude amber oil, cade oil, origanum oil, etc. are
used in the artificial reproduction of the odor-type
which is today generally known in perfumery
circles as a Leather type….
Rectified Birch Tar is a pale yellow to brownish
yellow, clear and oily liquid. The odor description,
"like Russian leather", is conventional, but
somewhat incorrect. Russian leather smells of
birch tar because the leather is tanned with the
tar products which also preserve this special type
of leather. This circle of odor association is
similar to the well-known: vanillin smells of
chocolate!…...
The odor of BirchTar Oil is distinctly phenolic,
very penetrating and diffusive, obviously remini-
scent of tar, charred wood and smoke (all of which
have their odor from components of the birch
tar oil!) However, the most characteristic feature
in the odor pattern of birchtar oil is the sweet-oily
undertone which appears distinctly on the smelling
blotter when the first empyreumatic notes have
faded away.
Amber pieces which are unfit for jewelry as
well as dust and residues from the gem industry,
etc. are submitted to dry distillation in order to
yield the so-called Succinol or Crude Amber Oil.
Crude (or pyroligneous) Amber Oil is a dark
amber-colored or brownish, but clear oily liquid.
Its odor is smoky, tarlike, resinous, with a
distinct resemblance to the odor of tanned leather.
The crude oil finds some application in perfumery
where it blends excellently with labdanum,
castoreum, ionones, amylsalicylate, etc. and it is
sweetened with cananga oil, benzylsalicylate,
zingerone, etc. for typical "leather" bases, e.g.
in men's colognes and after-shaves….
Rectified Cade Oil is a clear, orange-brown to
dark brown, oily liquid with an intense "tar-like",
smoky-phenolic odor. Its use in perfumery is
limited to situations where a smoky-leathery,
woody-phenolic, dry and warm note is called for:
forest notes, leather-bases, fougeres, pine for
"men's fragrances", etc., and in the imitation of
certain essential oils, oakmoss, etc…..

A nu mbar of natural perfume materials are used in creating
the Leather Complex. As mentioned above Birch Tar, Cade,
Crude Amber(very seldom available) and natu rap isolates obtained from them form the basis of the Leather Complex but there are many ty pes of Leather Perfumes which include floral notes, mossy notes, creamy notes, spicy notes, woody notes etc
