Nitrostarch, dry or wetted with less than 20 percent water, by mass


Nitrostarch is a secondary explosive similar to nitrocellulose. Much like starch, it is made up of two components, nitrated amylose and nitrated amylopectin. Nitrated amylopectin generally has a greater solubility than amylose; however, it is less stable than nitrated amylose. The solubility, detonation velocity, and impact sensitivity depend heavily on the level of nitration Wikipedia
