Ethylene brassylate

Brassylic Acid. This acid is commercially available from Nippon Mining Company (Tokyo, Japan). It is made by a fermentation process (76). Several years ago, Emery Group, Henkel Corp. (Cincinnati, Ohio) produced brassyUc acid via ozonization of emcic acid primarily for captive use in making dimethyl brassylate and ethylene brassylate. A pilot-scale preparation based on ozonization of emcic acid has been described in which brassyUc acid yields of 72—82% were obtained in purities of 92—95%. Recrystallization from toluene gave purities of 99% (77). 

Miscellaneous Derivatives. Fimehc acid is used as an intermediate in some pharmaceuticals and in aroma chemicals ethylene brassylate is a synthetic musk (114). Salts of the diacids have shown utUity as surfactants and as corrosion inhibitors. The alkaline, ammonium, or organoamine salts of glutaric acid (115) or C-5—C-16 diacids (116) are useflil as noncorrosive components for antifreeze formulations, as are methylene azelaic acid and its alkah metal salt (117). Salts derived from C-21 diacids are used primarily as surfactants and find apphcation in detergents, fabric softeners, metal working fluids, and lubricants (118). The salts of the unsaturated C-20 diacid also exhibit anticorrosion properties, and the sodium salts of the branched C-20 diacids have the abUity to complex heavy metals from dilute aqueous solutions (88). 

The compound is used in perfumery as a musk fragrance, but is not as long-lasting as the following homologous compound, ethylene brassylate.

Ethylene brassylate is used in large amounts in perfumery as a fixative and for rounding off sweet-flowery odor notes. 

Otherwise, in general construction the perfume follows closely that of a classical oriental, with citrus oils (making up some 25%), lavender, sandalwood, patchouli, vanillin, coumarin, castoreum, and rose. The general sweetness of the perfume is further enhanced by the choice of musk materials, Galaxolide (5%), Tonalid, ethylene brassylate, and musk ketone, as well as by the use of Cashmeran, an intensely sweet fruity musk material associated with the synthesis of Galaxolide. 

In Casmir the same technique is used but in an oriental context. The formula is constructed around large amounts of Hedione (20%), Galaxolide and ethylene brassylate, a combination of Iso E super and Vertofix, and vanillin (14%), which together make up some 80% of the formula. In deference to the oriental character linalool and linalyl acetate are present to provide a top note with traces of rose, vetiver, and patchouli, in the background. A strong fruity note, characteristic of many modem American perfumes, is also included.
