Abstract From the Canadian patent
A thickened water-based, salt-containing explosive composition is provided wherein the sensitising agent comprises a mixture of a soluble fuel such as dimethyl sulphoxide, sugar or formamide and an auxiliary sensitising material such as ethylene glycol mononitrate. The mixture produces a synergism which results in marked improvements in sensitivity in aqueous slurry explosives containing the sensitizer blend.
