Abstract: Sulfur-free and carbon-free, white propellant compositions for use as a blackpowder substitute in firearms, munitions, and pyrotechnics to form combustion byproducts that are water soluble and are free of corrosive sulfur compounds and black carbon residues. Formulations include a fuel agent selected from the group consisting of sodium benzoate, lactose, sodium salicylate, sodium m-nitrobenzoate, and mixtures thereof. The fuel agent is combined with dextrin, potassium nitrate, potassium perchlorate, and tricalcium phosphate. Dicyanodiamide may be incorporated in the formulation as a burn rate modifier.

Abstract: Sulfur free propellant compositions for use as a blackpowder substitute in firearms, munitions, and pyrotechnics to form combustion byproducts that are water soluble and are free of corrosive sulfur compounds. Formulations include an ignition aid of a gluconic acid salt or an alkali metal nitrobenzoate salt or a mixture of the two salts in combination with various known oxidizing and reducing agents and with various known propellant additives. The oxidizing and reducing agents may be selected from the group consisting of carbon, lactose, potassium nitrate, potassium perchlorate, sodium benzoate, and mixtures thereof. The propellant additives may be selected from the group consisting of binders, burning rate modifiers, flow agents, colorants, coating agents, moisture retardants and mixtures thereof.
