Tonka Bean - Coumarin Oil
About 90% of modern perfumes contain coumarin, you can easily detect it by reviewing the list of ingredients on the perfume packaging. Every second perfume has more than 1% of coumarin.
The scent of coumarin is usually described as freshly mown hay. In low concentration coumarin really reminds somewhat of rotting hay, but in a big quantity it has a sweet gourmand, almond-vanillic aroma. Thus gourmand perfumes have it the most. In descriptive lists of perfume notes it might hide behind tonka beans, vanilla, marzipan or tobacco.
