DE 102005041005 A1 UPAB: 20070510 NOVELTY - Composition comprises nano-particulate silver and further at least a component of silver salts, nano-particulate zinc oxide, chitosan and its derivative. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) masterbatch for the composition containing of 1-50 mass.% of nano-particulate silver, silver salt, nano-particulate zinc oxide, chitosan and its derivative; and (2) a method for the preparation of biocide containing products comprising introducing and/or applying the composition in and/or on the products. USE - The composition is useful for the preparation of: biocides; surface-active medicine products such as catheter, heart valves, surgical instruments, implants like bones- and/or cartilage materials, tooth implants, sore basis and sanitary articles; anti-fouling composition; wood laminating agent; carpets or mats; floor coverings and surface coatings, which are contacted with food. The composition is useful for: surface coating of plastics, air conditioning systems, fibers, fabrics, textiles and paper; cleaning minerals or artifical resins; combating biological materials (all claimed). ADVANTAGE - The composition exhibits improved biocidal effect.
