Guncotton is a nitrocellulose of high nitrogen content that is employed extensively in the manufacture of single-base propellants. It is also used in electric primers and in electrically initiated detonators. In most propellants, guncotton is blended with pyrocellulose where an increase in nitrogen content is desired. It is sometimes referred to by various names, such as pyropowder, pyrocellulose, or nitrocellulose.
