Uses in perfumery

Extensively used in perfumery to support herbaceous odors, Lavender, Lavandin, Rosemary, Citrus oils, Oakmoss, etc., and as a fixative in numerous types of fragrances. Almost a standard ingredient in Fougére types with Amylsalicylate and Lavender-notes, with or without Oakmoss. A classical masking agent for Jodoform odor, Phenolic odors, Quinoline odors, etc.

Uses in flavor

Extracts of certain botanical materials, rich in Coumarin, are still in use as Tobacco flavoring agents and in other flavors.

Production
