The present invention provides novel antimicrobial immobilized 1,2- benzisothiazolin-3-one/zinc oxide (BIT/ZnO) complexes useful as antimicrobial agents because of their resistance to being leached from the substrate to which they are attached. The present invention is also directed to methods for preparing the BIT/ZnO complexes, to BIT/ZnO complexes prepared by the novel methods, to methods for using the BIT/ZnO complexes to inhibit microbial growth or reduce the level of bacteria on the surface of a substrate, and to substrates protected from microbial attack by being treated with the BIT/ZnO complexes. The present invention is further directed to compositions comprising 1,2-benzisothiazolin-3-one which has been immobilized with zinc oxide.
L'invention concerne de nouveaux complexes immobilisés antimicrobiens de 1,2- benzisothiazolin-3-one/oxyde de zinc (BIT/ZnO) servant d'agents antimicrobiens en raison de leur résistance à la lixiviation à partir du substrat auquel ils sont fixés. L'invention concerne également des procédés de préparation de ces complexes BIT/ZnO, des complexes BIT/ZnO préparés par les nouveaux procédés de l'invention, des procédés d'utilisation desdits complexes BIT/ZnO destinés à inhiber une coissance microbienne ou à réduire le taux de bactéries à la surface d'un substrat, et des substrats protégés des attaques microbiennes grâce à un traitement faisant intervenir les complexes BIT/ZnO. L'invention concerne encore des compositions comprenant de la 1,2-benzisothiazolin-3-one qui a été immobilisée par de l'oxyde de zinc.
