Functions of Silver in ALSTASAN SILVOX

Oligo-Dynamic Function

Silver shows oligo-dynamic effect or toxicity on bacterial cells even in relatively low concentrations. Silver ions denature enzymes of the target cell or organism by binding to reactive groups, resulting in their precipitation and inactivation. Silver inactivates enzymes by reacting with the thiol groups to form silver sulphides.

Stabilizer function

Hydrogen Peroxide is not stable which means that it decomposes to oxygen and water. To solve this problem silver is added to hydrogen peroxide as stabilizer. Thi stabilizer prevents the slow decomposition of the hydrogen peroxide. The Ag (2+) ions keep O (2-) ions.

Activator Function

The silver performs as an activator. The singularity of this silver activator is that it only activates the peroxide when it is exposed to biofoulants. In contact with microbes the silver loses its stabilizing function and activates to release nascent oxygen to oxidize the exposed microbes. When all bacteria have been oxidized by the generated active oxygen compounds, the silver acts as stabilizer for the remaining and non-reacted oxygen.
