A soft composite explosive composition is made by forming an oil-continuous, melt-in-fuel emulsion in which the discontinuous phase is comprised of ammonium nitrate and other ingredients which together form a eutectic mixture. The continuous phase includes a combination of fuels and emulsifiers constituting less than 2.5% by weight of the formulation. Soluble compounds such as self-explosive compounds or compounds which can be converted to explosive compounds in situ may be added directly to the discontinuous phase along with one or more oxidizer salts.
