Method of maximizing stability and minimizing production of toxic fumes as explosion by-products by utilizing a moisture resistant blasting composition and said composition, comprising an invert emulsion component having, as the continuous external organic phase thereof, a partial ester of a 2-12 carbon polyhydric alcohol and a tall oil fatty acid, said explosive composition being capable of utilizing sufficient solid oxygen-supplying salt to obtain an Oxygen Balance of about zero without substantial loss of sensitivity.

A blasting composition comprising (A) an invert water/oil emulsion component consisting essentially of (a) an internal discontinuous aqueous phase containing about 50-90 weight percent of a water soluble inorganic oxygen supplying salt; and (b) an effective amount of a continuous hydrophobic organic phase of a partial ester of a 2-12 carbon polyhydric alcohol esterified by a tall oil fatty acid, (B) a solid oxygen-supplying inorganic salt to obtain an Oxygen Balance of about zero, (C) 0% to about 50% by volume of a density control agent; and (D) 0% to about 40% by weight of a sensitizer.
