Nitrostarch

Nitrostarch is similar to nitrocellulose and is sometimes used as a substitute for TNT, but it is less powerful. It cannot be made to gel and it is not soluble in water. It will dissolve in acetone and alcohol-ether mixtures.

Explosive Grenite is used for filling grenades and manufactured by the Du Pont Company, December, 1918.
Grenite is 95% nitrostarch and 5% binders.
