Castor is a secretion found in both sexes of the beaver, and it accumulates in two pear-shaped bags on the abdomen of the animal. The sacs are about the length of a finger, and at the thickest point are about the diameter of the thumb. They contain a greasy mass of yellowish-brown, reddish or blackish viscous substance. ("A Subtle Something" by Charles J. McGuirk Saturday Evening Post. Dec. 4, 1926).


An animal secretion, the castor, used in perfumery, is chiefly employed as a fixative. It consists of the dried membranous follicles of the beaver. They are filled with a strong smelling secretion which, when diluted, is not disagreeable, the odour being due to an essential oil it contains. (The Mystery and Lure of Perfume, 1969, p. 205).

Sécrétion odorante du castor, employée en pharmacie et en parfumerie.


Les [...] produits naturels d'origine animale, [...] musc, civette, ambre et castoréum ont pratiquement disparu du marché; leurs odeurs caractéristiques ont été reproduites par la synthèse chimique, à l'exception peut-être du castoréum, dont l'odeur est extrêmement complexe.
