Hydrogen peroxide readily decomposes, especially in contact with organic material. This produces highly reactive, short-lived atomic oxygen. This reacts with and attacks the surface of microorganisms.
Oligodynamic effects take some time to kick in and are not equally effectively against all micro-organisms. Silver therefore primarily exerts a long-lasting, preservative, bacteriostatic effect.
Higher doses of silver do not necessarily work faster or better. One option, therefore, is to enhance the biocidal effect of silver by using it in combination with other substances.
In combination with oxidising substances such as hydrogen peroxide, the effects are synergistic, producing a highly effective biocidal complex.
The term ‘heavy metal’ is generally used to refer to a group of metals with densities greater than 5.0 g/cm³. Under this definition, silver, which has a density of 10.49 g/cm³, is indeed a heavy metal – as are iron (7.9 g/cm³), nickel (8.9 g/cm³), copper (8.9 g/cm³) and gold (19.32 g/cm³). Heavy metals which are particularly resistant to corrosion are known as noble metals. These include gold, silver and platinum group metals. It is their corrosion resistance and lack of reactivity that makes noble metals suitable for use in jewellery and dental implants.
Like almost everything else in this world (salt, alcohol, water, Big Macs, etc.) silver is not completely ‘non-toxic’. “The dose makes the poison,” as the famous pharmaceutical saying goes.
A number of different maximum doses are therefore defined for silver, depending on the form in which it is used. Conversely, this means that as long as these permitted doses are not exceeded silver is harmless and therefore non-toxic.
Hydrogen peroxide is made up of oxygen and hydrogen atoms. It decomposes into water and oxygen without leaving any residue, and is a powerful oxidising agent. This means it can be harmful at higher concentrations or in greater quantities. At low doses or appropriately diluted, it is immediately neutralised by the catalase and peroxidase enzymes produced by our bodies, which break it down into water and oxygen. Hydrogen peroxide solutions are used in the healthcare sector for direct disinfection on or in people, e.g. disinfecting the mouth or throat, bladder irrigation, dental cervix treatments, ear irrigation, etc. It is also used as a preservative and disinfectant in a variety of face creams.
The SANOSIL disinfectant is powered by the combined two-phase effect of the Hydrogen Peroxide and Silver. These active ingredients make our products unique and successful to eliminate several types of pathogenic organisms.
Hydrogen Peroxide is a chemical compound consisting of two hydrogen atoms and two oxygen atoms. It has the chemical formula H2O2. When it decomposes, Hydrogen Peroxide breaks down into water and oxygen.
Silver is a noble and heavy metal. Metal ions affect cell membrane permeability. This weakens sensitive micro-organisms and makes them more sensitive to oxidizing biocides. Silver is an element with symbol Ag.
The patented SANOSIL products contain the active ingredients hydrogen peroxide (CAS 7722-84-1) and silver (CAS 7440-22-4). Both products are listed at ECHA or European agency for chemical registration. Thus, the sale and use in the EU (and other states that follow their directives) is legal. Following the final EU assessment of the raw materials, the individual Sanosil products are registered in the respective product groups according to BPR.
Yes, there are. Word of the exceptionally successful combination of hydrogen peroxide and silver has of course spread and has spurred the occasional imitator into action. Fortunately, deliberate counterfeits (i.e. products which are fraudulently sold under the Sanosil name) are rare.
There are a few replicas which, as long as they are fresh, have a very similar concentration of active ingredients to the original. However, we have been told by a number of sources that the shelf life and stability of these products over a period of several months presents problems in many cases. In addition, many of our imitators do not have legal access to silver, to enable them to properly declare it in accordance with ECHA (European Chemicals Agency) regulations. As a result, these companies often either avoid mentioning the silver content or deny its biocidal effect, with silver instead being listed as a ‘hydrogen peroxide stabiliser’.
Although aerosol disinfection offers a complete and thus better coverage of all surfaces than wipe disinfection, it has a reduced penetration due to the relatively low quantities of disinfectants. Aerosol technology is an additional level of safety / measure to mitigate microbiological risks.
In 1980, an innovative young chemist, who would go on to be the CEO of Sanosil, noticed that there were very few water disinfection methods and products on the market and that all of the available products had serious drawbacks. They were either very short-lived (chlorine, bromine, or ozone) or very harmful to the environment (chromium, isothiazolinone, or QACs).
It would fantastic if someone could create a fast-acting, environmentally friendly disinfectant with long-lasting effects. Although combining hydrogen peroxide and silver is not a new idea, no-one had ever managed to combine the two without them sooner or later breaking each other down.
With the aid of countless attempts and the generous support of a former mentor and chemistry professor at the University of Zurich, he finally managed for the first time to produce a solution which was and remained stable. Sanosil Super 25 was born. After a lengthy odyssey of approval processes by the required approval authorities, patent offices and expert laboratories, he established the Sanosil AG company in 1982.
The original Sanosil composition and manufacturing process was patented in all relevant markets and industrial nations in order to protect our intellectual property. In 2011, we achieved market readiness for a modified, improved manufacturing process, which was also immediately registered for patent protection.
