About
An unsaturated leaf alcohol with a fresh green scent used in fragrance compositions; it is structurally similar to other alkenols that are classified as fragrance allergens in the EU.
Trans-2-Hexenol (leaf alcohol) is an unsaturated C6 aliphatic alcohol with a characteristic fresh green odor. It is naturally present in many fruits and plants. Like other unsaturated short-chain alcohols, it may act as a mild irritant at high concentrations. It is not specifically restricted in EU Annexes, but its structural similarity to known sensitizers warrants monitoring.
