The present invention is concerned with the flame-proof finishing of textiles, and provide, a flame-proofing composition capable of giving stable emulsions in organic water-insoluble solvents. The composition comprises a salt of (a) guandine or salts thereof with weak acids, dicyandiamide or cyanamide and/or reaction products thereof with formaldehyde, and (b) acid mono and/or diphospheric acid esters of alcohols having 1 to 4 carbon atoms, the salt of (a) and (b) having in aqueous solution a pH value of more than 3.6, and (c) 3 to 15% by weight, based on the weight of the solid content of the composition, of compounds having the general formulae: ##EQU1## and/or ##EQU2## x being equal to 2 to 15, R.sup.1 representing a saturated alkyl group having 4 to 18 carbon atoms, and R.sup.2 representing hydrogen or a methyl group. An advantage of the composition is that it can be applied from organic water-insoluble solvents.
