Other names :
5-ethyloxolan-2-one ; Gamma- caprolactone ; Dehydrotonkalide ; 4-ethyl butan-4-olide ; Gamma-ethyl butyrolactone ; 5-ethyltetrahydro-2-furanone ; 4-ethyl-4-butanolide ; 5-ethyl-dihydrofuran-2-one ; 4-ethylbutan-4-olide ; Hexan-4-olide ; Hexano-1,4-lactone ; 4-hexanolide ; 4- hydroxyhexanoic acid lactone ; Tonkalide
Volatility :
Head/Heart
Uses in perfumery :
Gamma-Hexalactone is used for a gourmet, sunny and milky tonality and to recreate an exoticism in fruity notes in particular.
Natural availability :
Gamma-Hexalactone is present in several fruits. However, it is synthetic Gamma-Hexalactone which is more often used in perfumery.
Year of discovery :
Data not available.
Other comments :
The smell of Gamma-Hexalactone is close to the one of Methyl Laitone® because of its fruity Coumarin note, reminiscent of coconut.
Price Range :
€€€
Stability :
Lactones tend to polymerize through time, making them more viscous and leading to a phase shift in alcohol.
