PCT No. PCT/GB87/00145 Sec. 371 Date Oct. 16, 1987 Sec. 102(e) Date Oct. 16, 1987 PCT Filed Mar. 2, 1987 PCT Pub. No. WO87/05187 PCT Pub. Date Sep. 11, 1987.A dry, water-soluble biocidal composition comprises (a) 0.01 to 5 parts by weight of water-soluble inorganic halide, (b) 25 to 60 parts by weight of an oxidizing agent which, in aqueous solution, reacts with the halide to generate hypohalite ions, (c) 3 to 8 parts by weight of sulfamic acid, (d) 0 to 20 parts by weight of a non-reducing organic acid, (e) 10 to 30 parts by weight of an anhydrous alkali metal phosphate, the parts by weight of the composition totaling 100, the pH of a 1% by weight aqueous solution of the composition being between 1.2 and 5.5, and the composition being characterized by lack of evolution of halogen at a pH less than 3.0 and a biocidal activity substantially greater than that produced by like compositions having inorganic halide concentrations greater than about 20%.
