The present invention provides a non-toxic water soluble, inorganic anti-microbial polymer for inactivating microorganisms. The polymer is obtained by forming an aqueous solution comprising alkali metal cations, phosphate anions, carbonate anions, and hydrogen ions. The polymer has antimicrobial activity while in suspension and forms a hard, contiguous, encapsulating antimicrobial transparent film when dry. The film physically disrupts encapsulated microorganisms as it is formed and once formed does not support surface microbial growth. |
