Nitrostarch, which is closely related to nitrocellulose, attracted early attention, but it was not until about 1905 that it proved possible to produce it in a stable form. In general nitrostarch explosives are similar to the straight and ammonia dynamites except that nitrostarch is used in place of nitroglycerin. Disadvantages are its relatively low strength, mediocre water resistance, and the fact that it cannot be transformed into gelatinous products. Nitrostarch explosives, however, do not produce the headaches from skin contact that are characteristic of mixtures containing nitroglycerin. For that reason they are still marketed.
