Character
How it smells
Smoky, tarry, unapologetically raw rubber.
The word comes from indigenous Amazonian languages, meaning 'weeping tree', describing how latex flows from tapped bark.
Origin
Brazil
Amazonian peoples discovered Hevea brasiliensis latex millennia ago, using it for waterproofing and tools. When European explorers documented 'caouche' in the 18th century, they encountered a material that seemed almost magical. French chemist François Friedel exported the first rubber samples to Europe in 1763.
The industrial revolution transformed rubber into a strategic resource. Charles Goodyear's 1839 vulcanization discovery unlocked its commercial potential, fueling demand that would devastate wild Brazilian stands. By the 1870s, British smuggler Henry Wickham successfully transported seeds to Southeast Asia, launching plantation cultivation.
In perfumery, raw rubber absolute entered compositions in the early 20th century, lending distinctive leather and smoke accords to landmark fragrances.
