Constituent · Oxygenated monoterpene
decanal
decanal is an oxygenated monoterpene (an alcohol, ester, oxide or ketone) — the group that carries much of an oil’s characteristic aroma and softer character. Across our dataset it was measured in 16 oils (110 samples), concentrating most in Clove, Grapefruit, Ginger.
