摘要

Composition comprises nano-particulate silver and further at least a component of silver salts, nano-particulate zinc oxide, chitosan and its derivative. 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.
