An aqueous disinfectant composition, comprising trisodium phosphate, sodiumcarbonate, sodiumbicarbonate and a quaternary ammonium halide such as cetyltrimethylammoniumbromide isprovided. The aqueous disinfectant composition may comprise from about 0.25%to about 3.0%by weight of trisodium phosphate, from about 0.25% to about 3.0% by weight ofsodium carbonate,from about 0.25% to about 3.0% by weight of sodium bicarbonate, and from about0.001% toabout 0.1% by weight of a quaternary ammonium halide. The invention alsoincludes the use of acomposition, comprising trisodium phosphate, sodium carbonate, sodiumbicarbonate and aquaternary ammonium halide in the preparation of an aqueous disinfectantformulation.
