Volatility :
Heart/Base
Uses in perfumery :
Gamma-Decalactone adds a fruity and velvety touch to floral accords. Used in peach reconstitutions, accompanied by Aldehyde C14.
Natural availability :
Gamma-Decalactone is included in the fragrant principle of many fruits such as apricot or peach, and can be extracted from Osmanthus Absolute or from Carrot Leaf EO.
Year of discovery :
Data not available.
Other comments :
Gamma-Decalactone has a more sweet and syrupy peach side, while Aldehyde C-14 is renowned for its paper-like note.
Price Range :
€€€
Stability :
Lactones tend to polymerize through time, making them more viscous and leading to a phase shift in alcohol.

Synthesis route :
Gamma-Decalactone is part of the family of gamma-lactones: cyclic esters whose cycle consists of five atoms. This molecule is synthesized biochemically. A beta-oxidation of ricinoleic acid (derived from castor oil) causes the formation of 4-Hydroxydecanoic acid, which can be cyclized at an acidic pH to obtain the final product: gamma-Decalactone.
Synthesis precursor :
Gamma-Decalactone is not a precursor to the synthesis of another compound of olfactory interest.
Isomerism :
Gamma-Decalactone has an asymmetric carbon. However, it is its racemic mixture that is used in perfumery.
Delta-Decalactone is a constitutional isomer of Gamma-Decalactone, having one carbon atom less in its cycle, and one more in its ramified carbon chain. The resulting smell is very peachy for the isomer, and coconut-like for Delta-Decalactone.
