It was one of the first synthetic materials ever used in perfume, and it still sits at the heart of the fougère family and most tobacco, lavender and gourmand fragrances.

It is fairly tenacious and stays on a strip well into the dry-down.\u003c\/p\u003e\n\u003ch2\u003eHow perfumers use it\u003c\/h2\u003e\u003cp\u003eThe classic pairing is lavender plus coumarin plus a mossy base: that is the fougère idea in one line. Coumarin also rounds out tobacco, tonka and amber accords and gives gourmands a less sugary sweetness than vanillin. It is a crystal, so dissolve it first. Ethanol, DPG or benzyl benzoate all work, and gentle warming helps.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBlends well with:\u003c\/strong\u003e Lavender, Vanillin \/ Ethyl Vanillin, Ambroxan, Cedrol, Musks.\u003c\/p\u003e\n\u003ch2\u003eIFRA \u0026amp; regulatory\u003c\/h2\u003e\u003cp\u003eRestricted under the IFRA Standards (51st Amendment, in force).
