Chlorophyll in Perfumery | Première Peau

Raw, juicy green -- the smell of crushed stems and torn leaves before any single plant character emerges. Sharper than basil, less bitter than galbanum, with a faintly metallic, almost bloody quality (from the iron in chlorophyll's breakdown products). This is green at its most elemental: a lawn mower, a snapped stem, a handful of grass.

Chlorophyll itself -- the magnesium-porphyrin pigment responsible for photosynthesis -- has no significant odour. What perfumery calls 'chlorophyll' is the complex of volatile compounds released when plant cells rupture: cis-3-hexenol (leaf alcohol), cis-3-hexenal (leaf aldehyde), trans-2-hexenal, and various related C6 aldehydes and alcohols known collectively as green leaf volatiles (GLVs).

These GLVs are produced enzymatically within seconds of tissue damage -- the same biochemical cascade triggered by mowing grass, tearing herbs, or crushing leaves. The scent is universal across the plant kingdom: nearly all green plants produce the same core molecules. In perfumery, 'chlorophyll' is shorthand for this hyper-green, freshly-cut-plant impression.

The note functions as a top-note green modifier. It provides an immediate, raw vegetal impact -- greener than galbanum (which is also resinous), sharper than violet leaf (which is also powdery). Key synthetic materials: cis-3-hexenol (leaf alcohol), cis-3-hexenyl acetate (leaf acetate), cis-3-hexenyl salicylate. The note dissipates quickly due to high volatility.
