Abstract

An explosive composition is disclosed which comprises a discontinuous oxidizer phase comprising at least one oxygen-supplying component, a continuous organic phase comprising at least one water-immiscible organic liquid, and an emulsifying amount of at least one nitrogen-containing emulsifier derived from (A) at least one carboxylic acylating agent, (B) at least one polyamine, and (C) at least one acid or acid-producing compound capable of forming at least one salt with said polyamine. These explosive compositions can be water-in-oil emulsions or melt-in-oil emulsions. They can also be explosive compositions derived from such emulsions wherein at temperatures below that at which the emulsion is formed the discontinuous phase is solid or in the form of droplets of supercooled liquid.
