The hydrocarbon may be fuel oil, gasoline, kerosene, diesel oil, paraffin oil, benzene, toluene, or xylene. The thickening agent for the aqueous solution may be a biopolymer produced using the microorganism Xanthomanos campestris, or an alkyl-substituted guar gum, which may be supplemented by a normal guar gum, a starch or a polymeric product, together with sodium dichromate as a cross-linking agent. Sodium nitrite may be added as a gassing agent, or air may be stirred in, in order to reduce the density of the composition. Other optional ingredients are particulate aluminium, magnesium alloy, sulphur, vegetable grains, starch, thiourea, ethylene glycol and formamide. Additional dry particulate oxidizer salt may also be added.
