Delta-decalactone

Uses in perfumery :

Delta-Decalactone is used for coconut reconstitutions, but also to bring a fruity and milky effect in sandalwood or fruity compositions for example.

Year of discovery :

Data not available.

Natural availability :

Delta-Decalactone is found in the odorous principle of many fruits as coconut, peach, raspberry, apricot and some cheeses. It does not exist on a natural state for perfumery.

Isomerism :

Delta-Decalactone has one asymetric carbon. A mixture of its enantiomers is used for 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.

Synthesis precursor :

Delta-Decalactone is not used for the synthesis of another compound used in perfumery.

Synthesis route :

Delta-Decalactone can be prepared by oxidation of 2-pentylcyclopentanone, using a peracide.

Stability :

Lactones tend to polymerize through time, making them more viscous and leading to a phase shift in alcohol.

Other comments :

Comparing with other lactones, Delta-Decalactone is without a doubt one of the most coconut-like one, with no real peach effect.

This ingredient does not contain any allergen.
