<p>The present invention relates to an antimicrobial composition comprising an isothiazolinone, such as l,2-benzisothiazolin-3-one, and a zinc compound selected from zinc salts, zinc oxides, zinc hydroxides or combinations there of. Useful zinc salts include for example, oxides, sulfates, chlorides, and combinations thereof. In use, the zinc from the zinc compound enhances the a ntimicrobial activity to the isothiazolin-containing composition. This enhan cement permits achieving the desired antimicrobial activity at a lower usage rate than is achieved using the isothiazolinone in the absence of the zinc compound. The antimicrobial composition can also contain co-biocides, such a s pyrithiones, including zinc pyrithione or copper pyrithione.</p> |
