    Abstract: Compositions comprising an ionene polymer and a pyrithione salt, wherein the two components present in a combined amount synergistically effective to control the growth of microorganisms such as bacteria, fungi, algae or mixtures thereof. The ionene polymer comprises the repeating unit of Formula (I); wherein R1, R2, R3 and R4 are identical or different, and are selected from hydrogen, C1-20alkyl and benzyl; A is a divalent radical selected from C1-10alkyl, C2-10alkenyl, C2-10alkynyl, C1-10hydroalkyl, symmetric or asymmetric di-C1-10alkylether, aryl, arylC1-10alkyl and C1-10alkylarylC1-10alkyl; B is a divalent radical selected from C1-10alkyl, C2-10alkenyl, C2-10alkynyl, C1-10hydroxyalkyl, symmetric or asymmetric di-C1-10-alkylether, aryl, aryl-C1-10alkyl, or C1-10alkylaryl-C1-10-alkyl; and X2- is a divalent counter ion, two monovalent counter ions, or a fraction of a polyvalent counter ion sufficient to balance the cationic charge in the repeating unit which forms the ionene polymer backbone. The preferred pyrithione salt is sodium pyrithione, zinc pyrithione, copper pyrithione, aluminium pyrithione or magnesium pyrithione.
