How it behaves

Olfactory profile

Family
green
Note tendency
Top
Descriptors
green

Extremely pungent, sulfurous top-note material with a sharp cress, watercress, and mustard-like character. In heavy dilution it reads as a green, vegetal, slightly radish/nasturtium facet; neat it is aggressive and almost gas-like. Used in trace amounts to give natural green-vegetable and cruciferous nuances.AI · claude-opus-4-7
