Stemone ®
Premium Synthetic Ingredient for Perfumery
Stemone® is a synthetic fragrance ingredient developed for its distinctive green, natural, and fruity-fig character. Known chemically as (NZ)-N-(5-methylheptan-3-ylidene)hydroxylamine, it provides a fresh, leafy nuance reminiscent of fig leaves, tomato stems, and blackcurrant buds. With medium odor strength and strong diffusive power, Stemone is primarily used as a modifier to enrich and modernize green top notes across floral, citrus, and fruity compositions. It blends particularly well with lily-of-the-valley, narcissus, mandarin, grapefruit, and other verdant materials.

What is Stemone®?
Stemone® is a low molecular weight oxime compound used in perfumery for its highly realistic green-vegetal character. Its structure includes a hydroxylamine functional group, forming a stable imine that gives it its characteristic leafy scent.
Initially developed and patented by Givaudan, Stemone is valued for its capacity to evoke the smell of crushed green stems and fig leaves, a quality rarely achieved with natural extracts alone. Its vivid green signature makes it a key component in modern green-fruity accords and naturalistic reconstructions.
Olfactory Profile and Perfumery Applications
Stemone delivers a fresh, green aroma often described as a hybrid between fig leaf, tomato stem, and blackcurrant bud. It balances green sharpness with smooth fruitiness, contributing to both realism and originality in top notes.
Its key functions include:
Reinforcing green freshness in fruity and floral compositions
Adding naturality to synthetic-heavy structures
Supporting leafy-herbal or citrus openings
Contributing to transparent fig, narcissus, or mandarin accords
Stemone is typically used in trace to moderate dosages due to its potency. It is especially valued in niche perfumery for its realism and vibrancy.
Industrial and Technical Uses
Stemone is exclusive to fragrance applications and not used in flavoring or other chemical sectors. Its typical uses include:
Fine fragrances
Functional perfumery (soaps, shampoos)
Botanical and vegetal-themed accords
“Greenhouse” or fig-type niche creations
