Chemistry & Uses
Uses in perfumery :
Cashmeran® is used in woody, spicy, coniferous and ambery notes. Often associated with Kephalis®, and more generally with woody-ambergris and tobacco notes.
Year of discovery :
Cashmeran® was discovered by scientist John Hall in 1969. At the time, he was working on low cost transformations starting with molecule structures such as pentamethylindane and tetramethylnaphthalène. Patent n°3,773,836 (US) published on Aug.18, 1969 by Hall.J for IFF
Natural availability :
Cashmeran® is not available in its natural state.
Isomerism :
Cashmeran® has an asymmetric carbon. It is nevertheless the racemic mixture of this molecule that is used in perfumery. Alpha-Irone and Isoraldeine® are constitutional isomers of Cashmeran®. However, they have a violet and orris smell, different from Cashmeran®.
Synthesis precursor :
Cashmeran® is not a precursor to the synthesis of another compound of olfactory interest.
Synthesis route :
One of the methods for synthesizing Cashmeran® is to oxidize pentamethyl tetrahydroindene in the presence of a cobalt naphthenate catalyst.
Stability :
Stable in perfumes and diverse functional bases
Other comments :
Cashmeran® has a very singular and complex smell, which differenciates it from any other molecule use din perfumes.
