Abstract

An aqueous antimicrobial composition comprises particles of a silver halide salt and polyvinyl alcohol (PVA). Preferably the silver halide is silver chloride and has a particle size of 100-200nm. The composition may further comprise a corrosion-inhibiting surfactant, a benzotriazole stabiliser substituted by one or more electron-withdrawing substituents, a hydrophobic polymer emulsion resin binder and/or an inorganic oxide. In another embodiment is a method for preparing the composition by controlled precipitation of silver halide in the presence of polyvinyl alcohol. Also claimed is the use of the antimicrobial composition to provide antimicrobial properties to compositions such as fabrics, textiles and wound dressings; or to articles such as furniture and medical devices; or to building materials; or to materials such as plastics and packaging; or to formulations such as paints, detergents and personal care product; or to films, coatings and surfaces.
