Description and usage notes:

Very intense, good tenacity, a classic aliphatic aldehyde with nuances of ambergris and incense among other notes. When smelt in concentration it is sweaty and metalic but in dilution floral and herbaceous qualities are revealed. Very different from other aldehydes except in power, it can also be used to enhance the effect of musks in a fragrance.

Arctander writes enthusiastically about it, including: “This aldehyde is probably one of the most preferred perfumery aldehydes with respect to ‘aldehydic topnote’. It blends very well with Galbanum, the Hexenyl family or the Methyl phenyl carbinyl esters, the Methyl-ionones or with Oakmoss. …  It lends excellent notes to a ‘Tabac’ base and blends well with Vetiver for such purpose. In Mimosa it will supply part of the peculiar dry notes, and in Ambre fragrances it is an almost inevitable component. Interesting effects are achieved with Ginger oil and Clary Sage.”
