Description and usage notes:
Characteristic sweet odour of tonka absolute in which it is the majority component. Coumarin has the distinction of being the very first synthetic ingredient used in perfumery (in 1882 by Paul Parquet for Houbigant in Fougère Royal).
In addition to tonka beans, coumarin is also naturally present in a number of herbs and various fruits, including for example strawberries, and can contribute to the sweetness of fruity odours as well as many other fragrance types.
This is a crystalline solid at room temperature and is sold in that form, though it can be supplied as a 10% solution if you prefer (please indicate your preference in the box at checkout).
Arctander describes it as “Sweet, herbaceous-warm, somewhat spicy odor, in extreme dilution more haylike, nut- Iike, tobacco-like…
Extensively used in perfumery to support herbaccous odors, Lavender, Lavandin, Rosemary, Citrus oils, Oakmoss, etc., and as a fixative in numerous types of fragrances;
Almost a standard ingredient in Fougère types with Amylsalicylate and Lavender-notes, with or without Oakmoss.”
