Ethylene brassylate is described by Elena Vosnaki as a “brassilic ester with floral woody facets, commonly used in cosmetics, because it acts as an odour neutraliser to the other chemicals used, as well as in fine fragrance.”Ethylene Brassylate (Musk T) is one of the cheaper priced synthetic musks.

Ethylene Brassylate is a Macrocyclic musk. Macrocyclic musks are the new generation of white musk molecules, and will eventually replace most if not all of the polycyclic musks. It is thought that Macrocyclic musks will eventually replace most if not all of the polycyclic musks. Polycyclic musks being the original “white musk” synthetics that were developed primarily for the laundry detergent segment of the market (via Claire Vukcevic on the fascinating editorial piece “The Murky Matter of Musk“). Where she states that people loved the smell of their laundry after using these laundry detergents, and soon there was a demand for that type of squeaky clean musk scent in perfume too.”

Irina on states reminds us that Ethylene Brassylate (Musk T) is a macrocyclic Musk it has less environmental impact than Galaxolide a polycyclic*.
