Description
Coumarin Product Overview
Coumarin (C9H6O2) is the lactone of o-hydroxycinnamic acid, which makes it a close structural relative of Cinnamic Acid. It occurs naturally in tonka beans, sweet clover, woodruff and cassia cinnamon. It forms colorless to white crystals that melt at around 68–71°C and dissolve readily in ethanol and oils, but only slightly in cold water.
Its main use is in perfumery, where it provides a warm, sweet, hay and tonka note and acts as a fixative. It is a cornerstone of the fougère fragrance family and pairs naturally with Vanillin in sweet, powdery and oriental accords. It is also widely used in soaps, detergents and other scented products.
It is regulated in several markets. It is a declarable fragrance allergen in EU cosmetics, its use in fragrances is subject to IFRA standards, and it may not be added as such to food in the EU or the United States. In industry, it is also used as a brightening and leveling additive in nickel electroplating baths and as a starting material for coumarin-based dyes and optical brighteners.
