Antimicrobial composition

摘要

A stabilized antimicrobial composition comprising (a) polymeric polyquaternary ammonium compounds and (b) an antimicrobial metal, such as elemental silver, alloys thereof or silver compounds. The antimicrobial composition may be used as a stand-alone composition, in an antimicrobial formulation, or in combination with medical articles or medical devices. The antimicrobial composition prevents silver-containing formulations and medical devices from discoloration and loss of antimicrobial activity.
