Olfactively, however, it sits right in tonka-coumarin territory: balsamic, powdery, with hints of orange flower and heliotrope.

Symrise states a use level of 0.1–5 %: at low doses it rounds off heliotrope and orange flower accords, at higher doses it becomes a balsamic tonka theme. The manufacturer also documents its use in fruit notes – grape and plum gain balsamic depth from Coumarone.\u003c\/p\u003e\n\n\u003ch2\u003eUse in perfumery\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFine fragrance: use level 0.1–5 % in the concentrate\u003c\/li\u003e\n\u003cli\u003eThe manufacturer's application and stability table covers approx. 0.3–8 % across eau de toilette, soap, lotion and detergent\u003c\/li\u003e\n\u003cli\u003eDocumented fields: floriental fragrances, heliotrope accords, fruit notes (grape, plum)\u003c\/li\u003e\n\u003cli\u003eIntended exclusively for perfumery purposes (manufacturer data)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003ePractical note: dissolving, storing, combining\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eDissolving:\u003c\/strong\u003e As crystals, dissolve before formula work – a 10 % pre-dilution in ethanol or DPG is usual and can be dosed precisely.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStorage:\u003c\/strong\u003e Store cool, dry, protected from light and tightly closed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCombining:\u003c\/strong\u003e Documented partners according to the manufacturer: floriental structures, heliotrope accords, orange flower and fruit notes such as grape and plum.\u003c\/p\u003e\n\n\u003ch2\u003eWhat Coumarone is – and what it is not\u003c\/h2\u003e\n\u003cp\u003eThe name is easily misleading, so for clarity: Symrise Coumarone is 2-acetylbenzofuran (benzofuran-2-yl methyl ketone, CAS 1646-26-0).
