Abstract
An emulsion explosive comprising a discontinuous oxygen-releasing salt phase, a continuous fuel phase and an emulsifier blend, said emulsifier blend comprising a first emulsifier component consisting of at least one emulsifier comprising a lipophilic moiety, being a polymer of a C.sub.2 to C.sub.6 olefin, and a hydrophilic moiety, being derived from an amine wherein the HLB of the first emulsifier component, as herein defined, is in the range of from 1.0 to 1.3 and a second emulsifier component and wherein the HLB of the emulsifier blend, as herein defined is in the range of from 1.4 to 3.0. Compositions of the present invention combine not only ease of formation and long term stability but also provide significant advantages in the refinement of emulsions and exhibit improved tolerance to shear allowing repumping and greater ease of handling.
