Abstract (en)
[origin: WO9601231A1] Water is treated with silver ions as an antimicrobial agent, accompanied by a complexing agent to render the silver ions more effective, more stable or both. The complexing agent is an organic ligand which forms a soluble complex with silver ions. Preferred are polymeric materials incorporating at least three carboxylate groups capable of coordinating to silver. Also preferred are amphoteric/zwitterionic surfactants and polyethers.
