Mushroom absolute (CAS 84649-97-8) — Green Base Note Fragrance Ingredient
Mushroom absolute
CAS 84649-97-8
What Is Mushroom absolute?
Mushroom absolute is a rare fragrance ingredient extracted from wild mushrooms, particularly prized in niche perfumery for its earthy, umami character. It’s found in avant-garde fragrances that push beyond traditional floral or citrus compositions. This ingredient matters because it brings a primal, forest-floor depth to perfumes – a raw connection to nature that’s neither sweet nor conventionally pleasant, but deeply compelling in artistic compositions.
Safety Profile
USE WITH AWARENESSWhat Does Mushroom absolute Smell Like?
Mushroom absolute unfolds with an intense damp earthiness – like walking through a misty forest after rain. The initial burst carries decomposing leaves and wet tree bark, evolving into a savory umami heart reminiscent of dried shiitakes and truffles. As it dries down, a faint leathery animalic quality emerges, underpinned by a persistent loamy depth. This is not a clean scent – it smells alive, fungal, and complex, with subtle shifts between fresh mushroom caps and dried specimens.

Chemistry, Properties & Perfumer Guide
The Chemistry
Mushroom absolute contains complex mixtures of volatile organic compounds including octenol (giving the characteristic fungal aroma), various sesquiterpenes, and mushroom alcohols. The extraction process typically involves solvent extraction of dried wild mushrooms, concentrating the lipophilic aroma compounds. Unlike essential oils, absolutes capture heavier, less volatile molecules that contribute to the deep earthy character.
