Ambergris is regarded as a morbid product of the sperm whale, found in its intestines and floating on the sea. In commerce it appears in irregular pieces of gray or gray-brown color. It is lighter than water, soluble in volatile oils, ether and hot alcohol; being nearly tasteless, it is, however, often used for fixing aromas, for which purpose it is extensively employed in perfumery. In the manufacture of carbonated beverages it enters sometimes into compound flavors for the aforesaid purpose.
