Ethylene Brassylate (a macrocyclic lactone) is one of the oldest white musks, being created by Dupont in 1934 when its potential was immediately noticed by Andre Fraysse who gave it its debut in fine fragrance by incorporating it into the musk fond of his masterpiece Arpège for Lanvin (launched seven years earlier) at just the time the company was exploding to industrial proportions. Ethylene Brassylate became extremely popular due to its ease of use (being a liquid) and the fact that it was considerably cheaper than the other non-nitro musks of the early 20th century, for example Muscone and Civetone (Ruzicka, 1926) and Exaltolide® (1930). This musk is very versatile and can be used in almost any fragrance, but it lends itself particularly well to scents needing a soft vanillic note in the dry down. It also has nuances of ambrette seed, fruit and a light powderiness. This is definitely a must-have musk.
