Publication number: 20030104074Abstract: Described is a process of producing a concentrated liquid biocide formulation. Mixed together are (a) bromine chloride or bromine and (b) an aqueous solution of alkali metal salt of sulfamic acid having a pH of at least about 7, in amounts such that (i) the active bromine content of the solution is at least about 100,000 ppm (wt/wt), and (ii) the atom ratio of nitrogen to active bromine from (a) and (b) is greater than 1 when bromine is used and is greater than 0.93 when bromine chloride is used. Use of bromine chloride as the source of the active bromine in the process is preferred because in the resulting aqueous compositions, all of the bromine of the bromine chloride is made available as active bromine in solution. In other words, the chlorine of the bromine chloride is converted in the process to dissolved alkali metal chloride salt, thereby liberating all of the bromine in the biocidal composition as active bromine capable of providing biocidal activity.Type: ApplicationFiled: October 10, 2002Publication date: June 5, 2003Inventors: Robert M.

Publication number: 20030059483Abstract: Manual warewashing in common food service locations is typically performed in a multicompartment sink within three or more basins. In one basin the ware is contacted with an aqueous solution of a detergent composition. The ware is cleaned using mechanical action to remove soil. The cleaned ware is often rinsed in a subsequent sink in a potable water rinse and is then sanitized in a sanitizing solution in a subsequent basin, typically the third sink in sequence. The sanitizing solution can be rapidly depleted during periods of large volumes of hand washed ware. In order to monitor and control the concentration of the sanitizer in the sanitizer sink, we have found that even highly oxidizing hypochlorite bleaches, if adjusted to an appropriate pH, can maintain substantial sanitizing capacity while not decolorizing otherwise oxidatively sensitive dyes.Type: ApplicationFiled: February 10, 2000Publication date: March 27, 2003Inventors: Eddie D.
