  • Publication number: 20030104074
    Abstract: 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.

  • Publication number: 20030059483
    Abstract: 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.

    Abstract: A tissue cell growth-promoting solution produced by this invention comprising water containing at least 1 to 500 ppm of active oxygen, when applied to a wound, supplies active oxygen originating from outside the biobody to supplement the active oxygen produced by the biobody's own protective system cells such as neutrophils and macrophages which gather at the wound site, thus increasing the concentration of active oxygen at the site of the wound, mimicking a state in which a large quantity of such bio-signals is secreted by the biobody itself, to promote the reconstruction of tissues, the action corresponding to the last of the four main steps involved in wound healing biochemical processes of “blood vessel reaction”, “blood vessel coagulation”, “inflammation”, “reconstruction of tissues” and which would otherwise have to rely on the natural healing power of the biobody itself.

    Abstract: The antimicrobial efficacy of N-chlorosulfamate solutions, namely buffered aqueous combinations of HClNSO3−(mono-N-chlorosulfamate) and Cl2NSO3 (di-N-chlorosulfamate), herein referred to as “stabilized hypochlorite”, can be markedly enhanced by the addition of certain organic dopants. The dopants themselves are select hypochlorite stabilizing agents, which are known to readily form stable organochloramides when reacted with “free” hypochlorite (HOCl or NaOCl). Highly effective antimicrobial enhancing dopants include 5,5-dialkyl hydantoins, arylsulfonamides, and succinimides. Examples of these include 5,5-dimethylhydantoin, benzenesulfonamide, and succinimide. Other, less effective dopants include glycolurils. Generally, the dopant is present in a minor mole fraction, relative to the molar amount of stabilized hypochlorite present in the enhanced antimicrobial solution.

  • Patent number: 6245361
    Abstract: An aqueous cleaning and disinfecting composition is disclosed that is a synergistic combination of (a) a sufficient amount of a chlorine-containing bleach compound such as sodium hypochlorite or sodium dichloroisocyanurate to provide from about 1,100 parts per million by weight of available chlorine level with (b) from about 600 to 800 parts per million by weight of bactericidal quaternary ammonium compounds such as mixtures of didecyldimethylammonium chloride and (C12-C16 alkyl)dimethylbenzylammonium chlorides. Such compositions are tuberculocidal at unexpectedly low concentrations. Also disclosed are two component compositions and methods of disinfecting surfaces containing tubercule bacilli and other pathogenic micro-organisms such as bacteria and viruses.

  • Patent number: 6210566
    Abstract: Nestable canisters for use in a dispersal valve that normally holds only a single canister with the nestable canisters suitable for replacing single canisters to enable a fluid mixing stream to be bifurcated and simultaneously but separately treat the water with different materials. The fluid mixing stream which normally flows through the set of ports that are used for dispensing only one solid chemical into the liquid stream flowing through the dispersal valve is bifurcated to provide for both dispersant type bacteria killing as well as in situ bacteria killing. In addition the nestable canisters are provided with an improved bactericide and algaecide for killing algae in the water and absorbing acids that might be generated by use of chlorine in the dispersal valve.
