About
An unsaturated aliphatic C6 alcohol with a vinyl-type double bond, used as a fragrance ingredient providing green, fruity, and slightly fatty notes. The allylic structure may increase reactivity compared to saturated analogs.
1-Hexen-3-ol is an unsaturated aliphatic alcohol (hex-1-en-3-ol) with the double bond allylic to the hydroxyl group. The C6 chain length and vinyl carbinol structure give it characteristic green, fruity, and slightly fatty odor notes. It is not listed in EU Annex II (banned substances) or Annex III (restricted substances) of the Cosmetics Regulation. The absence of GHS hazard classifications suggests a relatively benign profile at typical fragrance use concentrations, though the allylic unsaturation warrants consideration of potential oxidation products.
Skin benefits
- Fragrance ingredient with green, fruity notes
- Contributes to fresh, herbaceous fragrance compositions
Known concerns
- Allylic alcohol may form oxidation products during storage
- Limited long-term skin safety data
- Relatively short carbon chain limits bioaccumulation potential
