Claim:
An antimicrobial composition concentrate comprising pyrithione or a pyrithione complex in an amount of from about 0.05% to about 20 weight percent, a zinc source in an amount of from about 0.01% to about 5%, and an organic amine component in an amount of from about 30% to about 80%, said percents being based upon the total weight of the composition concentrate, said organic amine component comprising a first organic amine selected from the group consisting of 1,2-alkanolamines, 1,3-alkanolamines, and combinations thereof, in combination with second organic amine selected from the group consisting of monomeric and polymeric forms of 1,2-alkyldiamines, monomeric and polymeric forms of 1,3-alkyldiamines, and combinations thereof, with the proviso that the first organic amine is present in said antimicrobial composition concentrate in an amount sufficient to insure that said amine component is soluble in said antimicrobial composition concentrate.
