Antifungal compositions and method
Efficacious antifungal compositions are prepared comprising a mixture of a traditional fungicide and an ion-exchange type antimicrobial agent.
1 . An antifungal composition comprising a traditional antifungal agent in combination with one or more ion-exchange type antimicrobial agent.
2 . The antifungal composition of claim 1 wherein the ion-exchange antimicrobial agent comprises an antimicrobial metal ion or metal ion source.
3 . The antifungal composition of claim 2 wherein the antimicrobial metal-ion is selected from the group consisting of silver, copper, zinc, gold, mercury, tin, lead, iron, cobalt, nickel, manganese, arsenic, antimony, bismuth, barium, cadmium, chromium and thallium and combinations thereof.
4 . The antifungal composition of claim 1 wherein the ion-exchange type antimicrobial agent comprising one or more ion-exchanged antimicrobial metal ions and an ion-exchange carrier therefore selected from the group consisting of zeolites, hydroxyapatites, zirconium phosphates and other ion-exchange ceramic materials.
5 . The antifungal composition of claim 4 wherein the antimicrobial metal ion is selected from the group consisting of silver, copper, zinc, and gold and combinations of any two or more of the foregoing.
6 . The antifungal composition of claim 4 wherein the antimicrobial metal ions is silver, alone or in combination with copper or zinc or both.
7 . The antifungal composition of claim 1 wherein the antimicrobial agent is a zeolite having ion-exchanged silver ions, alone or in combination with copper ions or zinc ions or both.
8 . The antifungal composition of claim 1 wherein the antifungal active is an amide, acyl amino acid, anilide, benzanilide, furanilide, sulfonanilide, bezamide, furamide, phenyl sulfamide, sulfonamide, valinamide, antibiotic, strobilurin, chloroneb, chlorothalonil, dichlorobenil, dichloran, PCNB, benzimidazole, benzothiazole, bridged diphenyl, carbamate, benzimidazoylcarbamate, carbanilate, conazole, imidazole, triazole, copper, dicarboximide, dichlorophenyl dicarboximide, phthalimide, dinitrophenol, dithiocarbamate, cyclic dithiocarbamate, polymeric dithiocarbamate, imidazole, inorganic mercuric, organomercury, morpholine, organophosphorus, organotin, oxathiin, oxazole, polysulfide, pyrazole, pyridine, pyrimidine, pyrrole, quinoline, quinone, quinoxaline, thiazole, thiocarbamate, thiophene, triazine, triazole, urea, or borate fungicide.
9 . The antifungal composition of claim 1 wherein the antifungal active is a triazole, myclobutanil, imidazole, borate, isothiazolone, dithiocarbamate, and strobilurin fungicide.
10 . The antifungal composition of claim 1 wherein the fungicide is an organic fungicide or a salt thereof.
11 . The antifungal composition of claim 1 wherein the fungicide is a borate.
12 . The antifungal composition of claim 1 wherein the fungicide is not a copper-based fungicide.
13 . The antifungal composition of claim 1 wherein the fungicide is not a zinc based fungicide.
14 . The antifungal composition of claim 1 wherein the antifungal agent is aqueous based or substantially water soluble.
15 . The antifungal composition of claim 1 further comprising a binder selected from the group consisting of hydrophilic polymers, thermoset resins, thermoplastic polymer and silicates.
16 . The antifungal composition of claim 1 wherein each of the two actives is present in an amount that is conventional for its use and the level of antifungal activity is at least as high as would be in the absence of the antimicrobial agent.
17 . The antifungal composition of claim 1 wherein each of the two actives is present in an amount that is conventional for its use and the level of antifungal activity is higher than would be in the absence of the antimicrobial agent.
18 . The antifungal composition of claim 1 wherein each of the two actives is present in an amount that is less than conventional for its use.
19 . The antifungal composition of claim 1 wherein each of the two actives is present in an amount that, when used on their own, is ineffective or poorly effective for preventing the growth of mold.
20 . The antifungal composition of claim 1 wherein the fungicide is a complex or combination of two or more fungicide actives.
