Water in oil emulsion explosive compositions comprises a discontinuous aqueous phase comprising at least one oxygen-supplying component, a continuous organic phase, an emulsifying amount of an emulsifier composition comprising: the reaction product of an amine (C) characterized by the presence within its structure of at least one H-N group and an intermediate formed in the reaction of (A) at least one olefinic compound containing at least one group of formula (I) and (B) at least one carboxylic reactant selected from the group consisting of compounds of the formula (III) R<3>C(O)(R<4>)nC(O)OR<5> wherein each of R<3> and R<5> is independently H or a hydrocarbyl group, R<4> is a divalent hydrocarbylene group, and n is 0 or 1, and reactive sources thereof and optionally, from about 0.5 to about 2 moles, per mole of (B), of (D) at least one aldehyde or ketone; and optionally a sensitizer.
