Grass in Perfumery | Premiere Peau

Sharp, raw, universally green. The most elemental green smell: no flower, no herb, just torn plant tissue releasing its volatile arsenal. Wetter and juicier than dried hay, less bitter than galbanum, less herbal than basil. A faintly sweet undertone sits underneath the sharpness.

Grass in perfumery refers to the freshly-cut-lawn impression -- the specific blend of green-leaf volatiles (GLVs) released when grass blades are mechanically damaged. The key molecule is cis-3-hexenol (leaf alcohol, CAS 928-96-1), supported by cis-3-hexenal (leaf aldehyde), trans-2-hexenal, and cis-3-hexenyl acetate (leaf acetate).

These C6 compounds are produced enzymatically via the lipoxygenase pathway within seconds of cell damage -- a biochemical distress signal that attracts predatory insects to attack herbivores feeding on the plant. The smell of cut grass is literally a chemical cry for help.

In perfumery, grass works as a top-note green modifier of very high volatility. It provides an immediate, vivid green impact that dissipates rapidly. The note is central to green, aquatic, fresh, and outdoor compositions. Cis-3-hexenyl salicylate extends the green impression into the heart with better tenacity.
