Запах

Smoky-sweet, rubbery, with an organic-vegetal undertone. Less harsh than synthetic rubber, less acrid than tires. A milky, slightly fatty quality from the latex protein content. Smoked rubber sheets add a phenolic-creosote quality. Overall: warm, thick, organic — an industrial material with botanical origins.

Докладно

Caoutchouc is the raw, natural rubber obtained from the latex sap of Hevea brasiliensis. The word comes from the Quechua 'kawchu' (weeping tree) and refers specifically to unvulcanized natural rubber — a material with a particular sweet-smoky, organic smell quite different from the harsh chemical odor of synthetic rubber.

Fresh latex has a mild, slightly sweet, vegetal-milky smell. As it coagulates and dries, it develops the characteristic rubber odor — smoky, slightly acrid, with fatty-organic undertones from the polyisoprene degradation. The traditional smoking process used to cure rubber sheets (smoked sheets) adds a layer of phenolic, creosote-like character.

In perfumery, the caoutchouc note appears in avant-garde and industrial compositions. It provides an organic, vegetal-rubbery quality distinct from synthetic rubber or tire notes. The smoking process connection makes it compatible with smoky and leather accords.

Цікавий факт

Charles Goodyear discovered vulcanization (heating rubber with sulfur) by accident in 1839 when he spilled a rubber-sulfur mixture on a hot stove. Before vulcanization, natural caoutchouc was nearly useless — it melted in summer and cracked in winter.

Отримання й хімія

Спосіб отримання

Natural caoutchouc is obtained by tapping the bark of Hevea brasiliensis and collecting the latex sap. The latex is coagulated with acid, washed, and dried — either air-dried (pale crepe) or smoked over wood fires (smoked sheets). No fragrance-grade extraction exists; the note is reconstructed in perfumery.

Natural rubber (cis-1,4-polyisoprene). Elastic solid at room temperature. Tg ≈ -70 °C. In perfumery, the accord evokes rubbery, smoky, lactonic facets.

У парфумерії

Caoutchouc is a niche note used in industrial, leather, and avant-garde compositions. It provides an organic rubbery quality that is warmer and more vegetal than synthetic rubber. Built from smoky materials (cade oil, styrene traces), fatty-organic notes, and milky accords. Functions as a heart-to-base modifier. The phenolic smoke connection makes it compatible with leather and tobacco families.
