About this material
The Essence of Crushed Leaves and Freshly Cut Grass
Not to be confused with Cis-3-Hexenyl Acetate, Cis-3-Hexenol (also known as (Z)-3-Hexen-1-ol) is one of perfumery’s most authentic green materials, prized for its remarkably natural aroma of freshly cut grass, crushed leaves, and verdant garden foliage.
Often referred to as “Leaf Alcohol”, Cis-3-Hexenol occurs naturally in a wide variety of plants and forms part of a fascinating group of aromatic molecules known as Green Leaf Volatiles (GLVs).
These compounds are released when plant tissue is cut, bruised, or damaged, creating the unmistakable scent of a freshly mown lawn, snapped stems, and living greenery after rain.
Its odour profile is intensely fresh, crisp, and botanical, bringing an immediate sense of vitality and natural realism to fragrance compositions.
Perfumers utilise Cis-3-Hexenol to introduce vibrant green facets to floral bouquets, recreate the sensation of lush foliage, and enhance the freshness of citrus, herbal, and woody accords.
While closely related to Cis-3-Hexenyl Acetate, Cis-3-Hexenol possesses a distinctly greener, more natural and leafy character, whereas its acetate counterpart exhibits a fruitier, softer, and sweeter profile.
Particularly beautiful when paired with Oakmoss, Cis-3-Hexenol adds brightness and living green texture to classic chypre structures, evoking shaded woodland floors, moss-covered bark, and freshly crushed forest leaves.
It also blends harmoniously with galbanum, violet leaf, hyacinth, jasmine, vetiver, cedarwood, and aromatic herbs.
A truly indispensable ingredient for perfumers seeking to capture the pure essence of nature in bloom.

Creative directions, not tested formulas.An aromatic opening
With bergamot and a peel accordExplore a citrus-and-herb opening that keeps the herbal character distinct. Compare a brighter peel variation with a gentler citrus reference, noting whether the imagined result feels like a garden cologne or a more culinary aromatic study.
Herb among petals
With geranium and a floral accordPlace the herbal material beside a familiar flower, using the flower alone as your reference. Compare the green and floral impressions through the evaluation and decide whether the herb should read clearly or remain an accent.
Dry aromatic woods
With cedar-like and sandalwood directionsBuild a simple herbal wood sketch and compare a dry wood option with a smoother one. Keep the aromatic material constant so the study reveals which setting gives your idea the clearest shape and most useful contrast.
