Abstract
A foamed or aerated explosive composition containing a water-soluble organic nitrate sensitizer is provided which retains sensitivity for long periods in small diameter cartridges. The dissipation or migration of entrained air or gas in the composition is substantially prevented by incorporating a blend of a foaming surfactant and a stabilizing surfactant in chosen proportions.
