If there is a scent that can bottle the instant a scythe glides through a lush green lawn at dawn, it is cis-3 Hexenyl Acetate. Also known by the familiar name Leaf Acetate, this compound is a gift of nature, present in many plants such as green tea leaves, violet leaves, strawberry, and mint.

However, to capture its purest soul, science stepped in. Synthetic products have recreated this molecule with extremely high purity, removing impurities to preserve the sharpest and most faithful green note. Behind its simple appearance as a mobile, colorless liquid, it erupts with the fresh green smell of newly cut leaves, blended with a distinct fruity facet of green apple, pear peel, and a faint candy-like sweetness.

As a derivative of “Leaf Alcohol,” the discovery and successful synthesis of cis-3 Hexenyl Acetate changed how perfumers recreate nature’s scent. It allows them to precisely mimic the smell of morning greenery or unripe fruits, delivering a crisp green freshness in the top notes of perfumes and contributing naturalistic flavor effects in the food industry.

Description

Olfactorily, cis-3 Hexenyl Acetate is a declaration of freshness-a cool green breeze that energizes the opening. It belongs to the green/leafy (chlorophyll-like) family and plays a dual role: both a brilliant top note and a powerful modifier.

Its odor is strong and vividly fresh, instantly evoking freshly cut grass or crushed leaves. What makes it more distinctive than its close relative cis-3-Hexenol is the added sweetness of fruity nuances such as pear and banana. Its power is undeniable: very high intensity, immediate diffusion, and even a tiny amount can transform the entire first impression of a blend. Yet this burst is very short-lived, often lasting less than an hour on a blotter.

In formulas, it is used to give floral accords the feeling of fresh flowers still attached to their stems and leaves, or to add crispness and freshness to fruity accords such as green apple and strawberry. It is often paired with cis-3-Hexenol to build a complete green system: Hexenol provides the moist, dewy leaf aspect, while Hexenyl Acetate brings brightness and a fruity sweetness. Because it is so intense, perfumers typically “tame” it by diluting it to 10% or 1% before use, ensuring the green burst does not overwhelm other materials.

Applications

The explosive freshness of cis-3 Hexenyl Acetate appears across many areas of life-from Green, Floral, and Fruity perfumes to living spaces via room sprays and scented candles, bringing a clean, nature-adjacent feeling. It also shows up in shampoo, shower gel, body creams, and even in the food industry to create natural-tasting strawberry, apple, and berry profiles.

That said, its strength demands restraint. Typical usage levels in perfumery range from 0.1% to 1%, though it may be pushed higher in special cases. From a safety standpoint, it is a flammable liquid and should be stored carefully in a sealed container, away from heat and light to prevent oxidation.

Many famous “Green” perfumes-such as Vent Vert by Balmain-and modern creations that mimic green tea carry the signature of this material. Steffen Arctander emphasized it as one of the most important ingredients for creating a brilliant, fresh opening impression, delivering a distinctive “natural” effect that is difficult to replace.
