  • Patent number: 6518313
    Abstract: Solid sanitizing compositions have advantages over corresponding liquids and powders. A solid sanitizing product can be contained within a plastic bottle with a label indicating that the contents have antimicrobial or deodorizing properties containing a non-flowable solid composition having greater than about 0.02 percent by weight antimicrobial compounds. The preferred solid sanitizing compositions consist essentially of an antimicrobial compound selected from the group consisting of quaternary ammonium salts, fatty amines and diamines, chlorhexidine gluconate, phenol, derivatives of phenol, parachloro metaxylenol and mixtures thereof, and between 0 and 99.98 percent by weight of a cleaning composition. The solid sanitizing compositions can be effectively used with solid dispensers. The solid dispensers have a bowl with a drain at the bottom and an upward pointing spray nozzle.

  • Publication number: 20020177528
    Abstract: The present invention is directed to a biocontrol agent Plectosporium tabacinum and methods for the biocontrol of weeds using the biocontrol agent. Preferably the weeds are cleavers (Galium aparine L and Galium spurium L.), and the biocontrol agent is Plectosporium tabacinum CL98-103 (ATCC deposit PTA-3463). The biocontrol agent is effective against herbicide-resistant and herbicide-susceptible cleavers, and it may be used in conjunction with other herbicides.

  • Patent number: 6426317
    Abstract: Dry, stable, high available halogen sanitizing granular compositions with a rapid rate of dissolution comprising halogenated 1,3,5-triazine-2,4,6-triones and a dissolution accelerant that is an alkali metal salt of 1,3,5-triazine-2,4,6-trione are disclosed. The disclosed compositions may include inorganic and/or organic disintegration agents. Additionally, these compositions may contain other performance enhancing additives such as water clarifiers, algaestats/algaecides, surfactants, glidants, processing aids, and binders. These UV stable sanitizing compositions contain a high available halogen content, and are stable even when stored in high-humidity environments.

  • Patent number: 6380182
    Abstract: The invention relates to a method to inhibit bacteria from adhering to a submergible surface. The method contacts the submergible surface with an effective amount of at least one sulfamic acid or salt thereof to inhibit bacterial adhesion to the submergible surface. The invention also relates to a method for controlling biofouling of an aqueous system. This method adds an effective amount of at least one sulfamic acid or salt thereof to inhibit bacteria from adhering to a submerged surface within the aqueous system. This method effectively controls biofouling without substantially killing the fouling organisms. The sulfamic acid used in the method of the invention has the formula R1R2NS(O)2(OH). In this formula, R1 and R2 are independently a hydrogen, a C4-C20 alkyl group or a cyclohexyl group. However, R1 and R 2 are not both hydrogen.

  • Patent number: 6346262
    Abstract: Controlled release compositions of matter are disclosed comprising complexes for treating a population of one or more aquatic organisms in a column of water. The complexes comprise at least one system wherein the system comprises at least one bioactive agent as a component selected for treating a population of aquatic organisms, at least one carrier component, and at least one coating component for regulating the controlled release rate and release profile of the bioactive agent in water or at least one bioactive agent and one joint-function component that can serve as both a carrier and coating to regulate the controlled release rate and release profile of the bioactive agent in water, with or without optional binder components and/or additional formulation materials. The components are selected to sink or float so that the complexes will permeate and/or remain in any planar or volumetric segment of a water column for a period of time that is sufficient to effectively treat a population of aquatic organisms.
