Description
A grayish, wax-like material with a sweet spicy odor. Ambergris is formed in the intestinal tract of the sperm whale (Physeter catodon), possibly as a result of an infection. The lightweight wax pieces are obtained directly from whale bodies, floating in the sea, or washed up on beaches, especially China, Japan, Africa, the Americas, and Carribean islands. Ambergis is primarily composed of Cholesterol with smaller amounts of alkaloids, fatty acids, and ambrein. The wax has been used since antiquity as a spice in food and wine, and as a perfume. In perfumes, ambergris provides a scent and also serves as a fixative by decreasing the evaporation rate of other essential oils. Synthetic ambergris has been made using ingredients such as gamma-dihydro ionone and gamma lactone to reproduce the odor (Brady 1971).
