Iso E Super

Absolutely aphrodisiacal. Wicked space-filling transparent woody-ambery energy of pheromonal radiance: Complex, velvety, smooth! Sophia Grojsman was right: Hug me, Iso E!!

Iso E Super (Arborone). Discovered by John B. Hall and James M. Sanders of IFF in 1975 and first named 'Isocyclemone E' ('Scent and Chemistry – The Molecular World of Odors', Verlag Helvetica Chimica Acta/Wiley-VCH, 2012, p. 207–218), Iso E Super wrote perfume history in the 'hug me' accord of Sophia Grojsman, first featured in 'Tresor' (Lancome, 1990). Since then its transparent woody-ambery odor has shaped and defined modern perfumery like hardly any other material, and it has definitely been overdosed to the max like no other perfumery material except perhaps Hedione. We find ca. 18% of 'Iso E Super' in 'Aventus' (Creed, 2010) by Olivier and Erwin Creed, almost the same level as in 'Tresor', ca. 35% in Jean-Claude Ellena's 'Déclaration' (Cartier, 1998), ca. 43% in Pierre Bourdon's 'Feminite du Bois' (Shiseido, 1992), ca. 45% in Nathalie Lorson's 'Encre Noire' (Laliques, 2006), ca. 48% in Maurice Roucel's 'Kenzo Air' (Kenzo, 2013), ca. 51% in Evelyne Boulanger's ‘Incense Jaisalmer’ and ca. 55% in Bertrand Duchaufour's ‘Incense Kyoto’ (both Comme des Garçons, 2002). About 55% of Iso E Super are also present in Jean-Claude Ellena's ‘Terre d’Hermès’ (Hermès, 2006), ca. 65% in Geza Schön’s ‘escentrıc01’ (escentrıc molecules, 2005), ca. 71% in Jean-Claude Ellena's 'Poivre Samarcande' (Hermès, 2006), ca. 75% of Iso E Super in Patricia Choux's 'Orb_ital' (nomenclature, 2015), and there are some 80% Iso E in 'Perles de Laliques' (Laliques, 2006) again by Nathalie Lorson ('Scent and Chemistry – The Molecular World of Odors', Verlag Helvetica Chimica Acta/Wiley-VCH, 2012, p. 218). The 100% Iso E Super dose featured by Geza Schön in 'molecule01' (escentrıc molecules, 2005) finally is impossible to surpass!

While the main α-isomer of Iso E Super with the double bond between the bridgehead carbon atoms is very weak in odor with a threshold of 500 ng/l air, the β-isomer which accounts for <5% determines the odor of commercial grade Iso E Super and has been termed 'Iso E Super Plus'. Its (+)-(1R,2R,8aS)-configured enantiomer with a 100,000× lower threshold (0.005 ng/l air) than the commercial perfumery material was named'Arborone' by Sungwoo Hong and Elias James Corey. It is the minimum energy conformer of this Arborone which is portrayed here in the form of a pendant.

The dimensions of this Iso E Super pendant are ca. 3.5 cm × 2.4 cm × 1.8 cm, and the hole for the necklace (not included) has a diameter of ca. 2.8 mm. It fits nicely on a more delicate necklaces of up to 2.4 mm, and looks also stunning on gold or rose gold plated www.thomassabo.com Charm Club 'Glam & Soul' necklaces, though the eyelets need to be slightly tapered with a pair of pliers.
