Abstract: Described herein are clear coating antimicrobial compositions, methods of preparation, and uses thereof for conferring antimicrobial activity to a surface. One particular composition comprises at least one antimicrobial, a vinyl acetal derivative polymer binder and a solvent for solubilizing said at least one antimicrobial and said vinyl acetal derivative polymer binder. Another particular composition, comprises at least one antimicrobial and a binder polymer/solvent selected from an acrylic acid polymer, a polyester-based polymer, an epoxy-based polymer, and mixtures thereof.

Abstract: Described herein are antimicrobial nanoclay comprising two or more cationic antimicrobials. The nanoclay is a phyllosilicate clay and the two or more cationic antimicrobials are individually selected from the group consisting of a quaternary ammonium compound, a metal ion-containing, a cationic chelating agent, a cationic amino acid-based surfactant, a cationic antibiotic, and a cationic compound having a guanidine moiety. The two or more different antimicrobials are incorporated into the nanoclay by a cationic exchange process. Also described are methods for preparing such antimicrobial nanoclays. The antimicrobial nanoclays may be used for conferring antimicrobial activity to an article of manufacture and/or for providing antimicrobial activity to a surface.
