Novel flame retardant finishes comprising a water soluble quaternary phosphonium salt, a water soluble organic nitrogen containing compound, a haloalkyl phosphate of the formula <IMAGE> WHEREIN EACH X is independently selected from chlorine, bromine, and hydrogen, wherein a is an integer from 1 to 2, wherein n is an integer from 1 to 8, wherein m is an integer from 0 to n, provided that when n is 1, m is 0, and mixtures of said haloalkyl phosphates, an emulsifiying agent which is capable of passing the following three tests: (1) Solubility (Compatability) Test: said emulsifying agent (20 parts by weight) must be soluble in 80 parts by weight of said phosphate ester at less than or equal to 80 DEG C.; (2) Shelf Life Test: a blend of said emulsifying agent and said phosphate ester prepared as in the Solubility Test must remain in one clear homogeneous phase at 22 DEG C. for at least 1 hour; (3) Finish Formulation Test: a flame retardant finish within the scope of this invention is prepared and must remain in one homogeneous phase for a minimum of 1 hour at 20 DEG C. These flame retardant finishes are excellent for flame retarding textile materials including polyester/cotton blend fabrics.
