Cetyl alcohol - Cetyl alcohol

A higher alcohol with 16 carbon atoms bonded in a straight chain. It is also called 1-hexadecanol. In Europe and the United States, whales were caught in large numbers to obtain oil for lighting, and cetyl alcohol was prepared from spermaceti, one of the main components of spermaceti obtained from whales. It is a white solid that dissolves in organic solvents such as alcohol and ether, but not in water. It decomposes when distilled at normal pressure. It has been used in medicines and other fields as a base for ointments. The sodium salt of this sulfate ester is used as a detergent.
