The present invention relates to an antimicrobial composition containing photochemically stable silver complexes and micelle adducts. In particular, the invention relates to a neutral complex of monovalent Silver of formula Ag-L, wherein Ag is an Ag+ ion and L is a ligand of formula 4- mercaptophenylboronic acid, and wherein the silver ion is linked to the mercapto group of the ligand L. Furthermore, the invention relates to micelle adducts formed between such complexes and a cationic surfactant. La présente invention concerne une composition antimicrobienne contenant des complexes d'argent photochimiquement stables et des produits d'addition sous forme de micelle. En particulier, l'invention concerne un complexe neutre d'argent monovalent de formule Ag-L, dans laquelle Ag est un ion Ag+ et L est un ligand de la formule acide 4-mercaptophénylboronique, et dans laquelle l'ion d'argent est lié au groupe mercapto du ligand L. En outre, l'invention concerne des produits d'addition sous forme de micelle entre de tels complexes et un tensioactif cationique.
