Patent GB-781708-A (GB)
Title: Improvements in or relating to disinfectant composition
IPC: A01N59/10
Filed: 1955-02-25
Abstract: A dry, stable, non-interreacting disinfectant composition consists essentially of a dry mixture of chlorinated trisodium phosphate having at least 1/2 per cent of available chlorine, which phosphate serves to provide hypochlorite ions in aqueous solution, and a water-soluble alkali metal bromide, e.g. sodium bromide di-hydrate or hydrated sodium bromide which does not take-up water from the phosphate, the bromide serving to provide hypobromite ions in aqueous solution in the presence of hypochlorite ions.  Preferably the composition contains a sufficient proportion of the phosphate so that the amount of available hypochlorite substituent exceeds the equivalent amount of available hypobromite substituent, thus enabling a mixture of available bromine and chlorine to be present in an aqueous solution of the composition.  By chlorinated trisodium phosphate is meant a compound of trisodium phosphate in its normal Na3PO4.12H2O form combined with sodium hypochlorite.  U.S.A. Specifications 1,555,474 and 1,965,304 are referred to.
