Description and usage notes:

This is an extremely versatile ingredient, commonly used in floral accords but also essential in chocolate accords and useful in fruity complexes as well.

Arctander describes it as having a: “Powerful and very diffusive leafy-rosy-musky odor with exceptional topnote effect. Distinctly fresher and more diflusive (not really volatile) than the n-Butylester. Slightly waxy notes (fresh, Narcisse-like ) are typical of the pure product, while unpleasant or pronounced animal-honeylike notes dominate the poorer grades.”

He goes on to tell use that it “Finds extensive use in perfumery for fresh ‘petal’ notes in Rose, Peony, Narcisse, Carnation, Sweet Pea, Freesia, Hyacinth, etc.” 

Jean Claude Elena, in his book Diary of a Nose, suggests that in combination with Vanillin this material can produce an effective illusion of the smell of chocolate and says “To ‘make’ plain chocolate, I recommend adding patchouli; for a ganache a trace of civet; for ‘orangette’, orange zest; for an After Eight, spearmint; and for the smell of cocoa powder, concrete of iris.”  We suggest that you might substitute ethyl vanillin, which is often thought more chocolatey than vanillin; l-Carvone for the spearmint to avoid solubility problems; and Orris Givco for the concrete to avoid needing a second mortgage.

Additional ideas for a more authentic chocolate or cocoa accord are mentioned in the Cocoa Hexenal product description.
