As already mentioned, hydrogen peroxide works quickly. However, it then degrades and loses its effectiveness, allowing any surviving organisms to multiply again. We have therefore added silver ions to the formulation, which provide a longer-lasting antimicrobial effect as they remain on the disinfected surface. We looked for a suitable silver complex that would not impair the stability of the peroxide, as hydrogen peroxide quickly begins to decompose in the presence of free metal ions. Silver citrate proved to be the most suitable, and citrate ions also have a bactericidal effect.
