Quick Summary

Pyrocellulose, also known as guncotton, is a highly flammable compound derived from cellulose treated with nitric acid. It is a mixture of nitric esters of cellulose and is the primary ingredient in modern gunpowder. Highly nitrated pyrocellulose is unstable and ignites easily, making it suitable for explosives, gunpowders, and solid rocket propellants.1

Moderately nitrated cellulose, sometimes called pyroxylin, is less volatile and dissolves in alcohol and ether. This form is used in paints, coatings, and nail polish. The degree of nitration determines the solubility and flammability of the final product. Pyrocellulose was also historically used to create the first man-made fibers and plastics.1
