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.
La présente invention concerne un polymère antimicrobien inorganique, hydrosoluble et non toxique destiné à inactiver les micro-organismes. On obtient ledit polymère en formant une solution aqueuse comprenant des cations de métaux alcalins, des anions phosphates, des anions carbonates et des ions hydrogène. Le polymère manifeste une activité antimicrobienne lorsqu~il est en suspension et il forme un film d~encapsulation transparent antimicrobien, dur et continu lorsqu~il est sec. Le film perturbe physiquement les micro-organismes encapsulés lors de sa formation et, une fois formé, il ne donne pas lieu à une croissance microbienne en surface.
