A water-in-oil explosives composition comprising water, liquid or liquefiable carbonaceous fuel and inorganic oxidizer salt, optionally with gassing agent and/or thickening agent, and containing 0.02 to 2% of a stabilizer selected from organo-sulphur compounds, organic compounds containing quaternary nitrogen, phenolic compounds and substituted derivatives thereof, dihydroxybenzenes, quinones, unsubstituted and substituted aryl diazo compounds, unsubstituted and substituted aryl amines and salts thereof, and unsubstituted and substituted quinolines. Preferred stabilizers include thioureo, hydroquinone, anthraquinone, 1-phenylazo-2-naphthol, 1-[(4'-o-tolylazo)-o-tolylazo]-2-naphthol, N-phenyl-.alpha.-naphthylamine, N-phenyl-.beta.-naphthylamine, the condensation products of 1,4 dichloroanthraquinone with p-toluidine and 2,2,4-trimethyl-1,2-dihydroquinolines. The compositions have improved sensitivity and stability against phase separation at elevated temperatures and under cycling temperature conditions between -16.degree. and +50.degree. C.
