Silver – Born in the supernova
to protect man

At the end is the new beginning. How have the chemical elements been created since the beginning of time? The light elements hydrogen, helium and traces of lithium were created a few minutes after the Big Bang in our still very young universe.
All the heavier elements, such as gold, platinum or silver, were only formed later in the interior of stars or during stellar explosions, such as a supernova.

Stars explode as supernovas when their fuel is largely used up, and they have at least ten times the mass of our Sun. In this process, heavy elements such as silver are produced and hurled into space.

Silver was also part of the stellar dust from which our earth was once formed and has since been part of blue planets and was mined early on, for example in large silver mines such as in the town of Schwaz in the Tyrolean Alps.

lver has long been used for jewelry, coinage, means of payment and cutlery. Today silver, which among other things has the highest electrical and thermal conductivity of all metals, is used in countless high-tech and electronic applications. The antimicobial properties of silver were used early on to keep liquid food fresh for longer, for example. This laid the foundation for coatings for modern medical device technology. Silver also has antibacterial, antiviral and fungicidal properties.

Silver and modern medical device technology protect and heal

For some time now, technologies based on the antimicrobial effect of silver ions have been used primarily in medical devices. Silver-coated or silver-doped endoprotheses have long been able to be safely implanted in humans without any problems. 

Coatings on implantable textile medical devices prevent postoperative infections. Vacuum silver-coated medical textiles for neurodermatitis patients demonstrate the wide range of applications for the element silver, which has become an indispensable component in medical device technology. This is especially true for passive infection protection.

Effect on medical textiles by means

of positively charged triple action

Silver is not antimicrobially effective as an element per se, but permanently secretes the positive silver ion in very small quantities.

The positive silver ion develops a threefold mechanism of action, e.g. to inactivate a corresponding bacterium.

3-fold mechanism of action:

    • Locking of the cell membrane
    • Inactivation of bacteria‘s own S-protein
    • Blocking of oxygen-transporting enzymes

IONIC SILVER® MDR is used in hospitals and clinics as a preventive measure to form a passive infection protection barrier on medical textiles used there to largely prevent the transmission of methicillin-resistant Staphylococcus Aureus strain bacteria (MRSA).

The new ACC key technology

In order to transfer silver ions to a medical textile as easily, as permanently and as effectively as possible, a sophisticated technology is required.

The textile experts, who made the textile application of this technology possible at the beginning of the new millennium, have now been able to make another decisive technological leap in the IONIC laboratories. The formulation was not changed, but the crystallization form of the silver compound silver chloride used was optimized. A review of the past helped in this process.

Anyone who knows how matter interacts can arrange it more intelligently. This is how the revolutionary Advanced Core Crystallization (ACC) process creates the new optimized silver chloride crystal lattice of IONIC SILVER® MDR. The ACC process in combination with the low solubility of silver chloride develops maximum efficiency and conserves natural silver resources.

Top marks in the environment.

Silver ions are highly efficient and control bacteria even at a concentration of a few billionths of a gram. But what happens when silver ions enter the environment? The answer is surprising for many – nothing at all!

First of all, silver ions are permanently released from the environment into the environment via natural processes. Silver ions from textile washing, for example, are immediately inactivated to silver sulfite by sulfur-containing waste water components in the sewage system before they even reach the biological stage of a sewage treatment plant. The sewage plant can cope with the silver ion load in the effluent without any problems and works completely undisturbed as always!

Also to a concentration in the environment it does not come. The silver immissions by IONIC SILVER® into the environment are so low, correspond therefore to the average distribution of the silver in the earth‘s crust. An award-winning and very readable study, which was carried out in the tributary area of the alpine river Isar or in the German foothills of the Alps and Munich, proves this statement impressively. Hardly any other effective biocide can demonstrate such an environmental profile.

Biocide Regulation Guidance

So what makes a substance a biocide?

A substance such as lactic acid can be used in different ways. Lactic acid, for example, as a substance is a food additive permitted in the EU and is used under the label E 270. Lactic acid can also be used as a biocide and is subject to EU biocide regulation.

For example, the following aspects must be fulfilled in the EU Biocidal Products Regulation that a substance is subject to the BPR Biocidal Product regulation:

    1. That the substance has a proven biocidal effect
    2. That the substance is named or advertised as a biocide
    3. That the substance meets the specific biocidal active substance definition
    4. That the substance is legally covered for certain uses

If these points are fulfilled, special obligations are derived from it, among other things regarding the approval of the active substance, registration of the biocidal products formulated with the active substance and marking of the goods treated with it.

Conversely, within the CPD, with the exception of one product sector for a certain legal area, the Biocide Ordinance does not apply to the substance used in this area. An example for such an exception from a biocide regulation is the European Medical Device Regulation (MDR) within the legal framework of the CPD, for which IONIC SILVER MDR is designed to maintain the protection of the EU population due to the regulatory frenzy of the EU authorities.

How to use it in the textile finishing

IONIC SILVER MDR can be easily impregnated onto a medical textile or applied by the exhausting method
