  • Patent number: 4963366
    Abstract: According to the invention, a liquid deliquescent composition is substantially uniformly applied to grain, animal feed, animal feed ingredients, hay or poultry litter product, inhibiting moisture migration or translocation in the product and thereby inhibiting the formation of mold-generating accumulations of moisture adjacent the walls of storage containers for grain, animal feed, feed ingredients or hay which are subject to large overnight temperature drops, and similary inhibiting the formation of mold-generating accumulations of moisture adjacent the walls of grain elevators or silos subject to large seasonal temperature drops. Such inhibiting of moisture migration or translocation according to the invention also inhibits the formation of dry zones in grain, animal feed, feed ingredients, hay or poultry litter, thereby inhibiting the generation of dust from such products, including the inhibiting of dust generation during the screw-conveying of grain to storage.

  • Patent number: 4937072
    Abstract: The method comprises forming a sporocide having a defined period of sporocidal activity comprising three components including a peroxide or peroxide generating material, a peroxidase and a salt of iodide which serves as a donor molecule; storing the three components in a nonreacting state to maintain the sporocide in an inactive state and admixing the three components in a aqueous based carrier to cause a catalyzed reaction by said peroxidase for generating free radicals and/or byproducts from the iodide salt (donor molecule) and contacting the surface or object to be sterilized with the activated mixture. The concentration level of the three components can be selected such that an active sporocidal state is maintained for any desired period of time.

  • Patent number: 4935248
    Abstract: In the technology of applying, spraying, or sponging antimicrobially effective amounts of aqueous iodophor peroxide solutions to the udder surfaces of cows, or other animals to be milked prior to milking, the present invention comprises the improvement which avoids iodides and staining which consists essentially of the step of shampooing said udders with a non-staining shampoo containing (a) from about 0.5% to 2% of iodine in a povidone-iodine complex and (b) about 0.5% to 5% of hydrogen peroxide as a nascent oxygen source, said individual components (a) and (b) being combined, with water, at the time of use and having been maintained dry and out of contact with one another in a container or receptacle.

  • Patent number: 4847067
    Abstract: A mold and dust inhibiting composition which has particular utility in connection with the storage and handling of animal feeds, grains, and hay, and also in connection with the use of animal litter such as poultry litter, as well as having general utility for controlling both mold and dust. The composition of the invention is an aqueous solution of one or more salts of propionic acid, one or more deliquescent substances, and also preferably one or more humectants. Propionate ions are made available for mold control by this solution just as effectively as propionic acid, but without the disadvantages of propionic acid including a bad odor, serious corrosive characteristics, and high volatility and hence short residual time. The deliquescent, and preferably also the humectant, prevent moisture from migrating toward container walls where there is a large day/night temperature differential, and also prevent dry regions from developing and producing potentially harmful dust.

  • Patent number: RE36605
    Abstract: This invention relates to a disinfecting epidermal cleaner using peroxidase, peroxide and iodide. The active components are maintained inactive until admixed in a .[.define.]. .Iadd.defined .Iaddend.proportion with water. The pH at which the peroxidase is stored is between 7.0 and 9.0 and the pH of the admixture of the active components is between 3.0 and 6.5.
