Alstasan Silvox: SHP based Soil Disinfectant

Based on Hydrogen Peroxide and Nano Silver, stabilized in presence of a catalyst, for use as a multi-purpose and highly effective biocide. It is stabilized to prevent quick oxidation and degradation and a very potent disinfectant of soil and water. It is odourless, colourless, non-toxic, eco-friendly, biodegradable product which does not emit any harmful (fume either during applicable or thereafter).

This combination of peroxide with silver provides high efficacy in killing bacteria, fungi, pests, viruses, in all possible application methods. The process of disinfection is controlled by a store and depot action in which the hydrogen peroxide only gets activated on microbial contact and once the pathogen is killed, silver quickly stabilizes the peroxide to prevent further decay of the same. This store and depot action of silver provides a stable and long lasting disinfection.

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. This stabilizer prevents the slow decomposition of the hydrogen peroxide. The Ag2+ ions keep O2- 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.
