Catalog › Ethylene Brassylate + Tonka bean absolute
These two appear together in 7 of the accords published to the PerfuMate community. That is a record of two materials used together in real formulations, and it is only that: a record of use, not a recommendation engine. The accords are listed below so the evidence can be read.
They share no olfactive family: Ethylene Brassylate is filed under Musk, Sweet, Aldehydic, Powdery, Floral and Tonka bean absolute under Gourmand, Fruity. What joins them here is use, not classification.
Each accord is a formula published to the PerfuMate community, and these are PerfuMate's own reference accords rather than third-party work. The figures are each material's share of the concentrate in that accord.
