-Not a special compound, but a special delicate equilibrium of ten or so compounds makes this scent by the interaction of interaction of benzyl acetate (26.0%), anisaldehyde (0.1%), anisyl alcohol (0.2%), (E)-cinnamyl acetate (1.7%), and cinnamyl alcohol (1.3%), together with a series of derivatives of (E,E)-undeca-3,5-dien-2-one (0.2%), (E)-undec-5-en-2-one (1.7%), (E)-undec-5-en-2-ol (0.2%), (E)-undec-5-en-2-yl acetate (0.3%), and a distinct aura added by α-ionone and β-ionone. \\
