Запах
Докладно
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.
