An emulsion suitable for use as a flame-retardant for textile materials is prepared by dissolving 1,1,2,3,4,4-hexabromobutene-2 in an N-alkylpyrrolidinone in which the alkyl group has from 1 to 5 carbon atoms to form a solution containing from 15 to 50% by weight of 1,1,2,3,4,4-hexabromobutene-2, diluting this solution with an aromatic hydrocarbon, and mixing the resulting solution with a non-ionic emulsifying agent and water to form the emulsion.
