  • Patent number: 6241994
    Abstract: The invention provides a solid TCMTB formulation for controlling the growth of at least one microorganism. The use of a solid TCMTB formulation, as compared to a liquid, minimizes user contact and is more readily packaged. A solid TCMTB formulation of the invention contains TCMTB adsorbed onto a water-soluble, salt carrier matrix, with the TCMTB present in an amount effective to control the growth of at least one microorganism, preferably in an aqueous system. Other microbicides and additives may also be incorporated into a solid TCMTB formulation of the invention. In a preferred embodiment, the formulation contains both TCMTB and one or more other microbicides (e.g., methylene bisthiocyanate (MTC)) and a water-soluble, salt carrier matrix. The TCMTB is adsorbed onto the water-soluble salt carrier matrix. The TCMTB and other microbicide are present in a combined antimicrobial amount effective for the control of at least one microorganism.

  • Patent number: 5866016
    Abstract: The present invention relates to a method to inhibit bacteria from adhering to a submergible surface. The method contacts the submergible surface with an ionene polymer and a salt of dodecylamine in a combined amount effective to inhibit bacterial adhesion to the submergible surface. The present invention also relates to a method for controlling biofouling of an aqueous system. This method adds an ionene polymer and a salt of dodecylamine in a combined amount effective 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 present invention also relates to compositions containing an ionene polymer and a salt of dodecylamine and useable in the above methods. The compositions comprise an ionene polymer and a salt of dodecylamine in a combined amount effective to inhibit bacteria from adhering to submergible or submerged surfaces.
