The present invention is directed to an antimicrobial composition, comprising pyrithione or a pyrithione complex; and a zinc or copper or silver source selected from the group consisting of zinc or copper or silver salts, oxides, hydroxides, sulfates, chlorides, metals, and combinations thereof; wherein the weight ratio of the zinc or copper or silver source to the pyrithione or the pyrithione complex is in the range from about 1:300 to about 50:1, and wherein the antimicrobial composition has an enhanced biocidal effect against a variety of free-living microorganisms or biofilms. Also disclosed is a method of inhibiting the growth of free-living microorganisms or biofilm utilizing the above antimicrobial composition, as well as use of such antimicrobial compositions in various products including fuels, fluids, lubricants, coatings, adhesives, sealants, elastomers, soaps, cosmetics, plastic or woven or non-woven fibers, pharmaceuticals, and as preservatives for the above products.

Pyrithione biocides enhanced by silver, copper, or zinc ions

Disclosed herein is an antimicrobial composition characterized by synergistic antibacterial and antifungal efficacy and comprising a pyrithione salt or pyrithione acid, and at least one compound selected from the group consisting of benzyl and lower alkyl esters of para-hydroxybenzoic acid, salts thereof, carboxylic acids, salts thereof, and combinations thereof. Also disclosed is a method of imparting antimicrobial activity to a composition comprising water or an organic solvent which comprises adding thereto an antimicrobially effective amount of the above-described antimicrobial composition.

Synergistic biocide composition containing pyrithione plus an additive

A method and a kit for separating double-stranded nucleic acid molecules from a mixture containing both single-stranded and double-stranded nucleic acid molecules. The method is particularly suitable for separating hybridized from unhybridized probe nucleic acid.
