Novel flame retardant finishes comprising a water soluble quaternary phosphonium salt, a water soluble organic nitrogen containing compound, a phosphate ester of haloalkanols, an organic solvent characterized by having a flash point of at least 80.degree. F. and a boiling point within the range of about 300.degree. to about 350.degree. F., an emulsifier having a hydrophile lipophile balance value of from about 10 to about 14, and water. These flame retardant finishes are excellent for flame retarding textile materials including polyester/cotton blend fabrics.
