Napalm is an incendiary mixture of a gelling agent and a volatile petrochemical. The name is a portmanteau of two of the constituents of the original thickening and gelling agents: co-precipitated aluminium salts of naphthenic acid and palmitic acid. Napalm B is the more modern version of napalm and, although distinctly different in its chemical composition, is often referred to simply as "napalm".
