The active ingredient in the ÆGIS Microbe Shield products forms a colorless, odorless, positively charged polymer that molecularly bonds to the treated surface. You could think of it as a layer of electrically charged swords. When a microorganism comes in contact with the treated surface, the C-18 molecular sword punctures the cell membrane and the electrical charge shocks the cell. Since nothing is transferred to the now dead cell, the antimicrobial doesn’t lose strength and the sword is ready for the next cell to contact it. What is the purpose of the silane portion of the molecule? Silanes are extremely efficient bonding agents that can be coupled to other molecules and then used to permanently bond those molecules to a target surface. Our antimicrobial silane modifies virtually any surface and transforms it into a material that will not support microbial growth. Are the ÆGIS Microbe Shield products quaternary compounds? Yes and no. The ÆGIS active ingredient is an organofunctional silane, but part of the molecule is a quaternary compound. Unlike traditional quats, which have a limited kill spectrum, the ÆGIS technology provides long-term protection and controls a wide range of microorganisms including bacteria, fungus, algae, and mold. What is the difference between the ÆGIS Microbe Shield products and other antimicrobials on the market? Conventional products penetrate living cells and kill by way of poisoning the organism or disrupting a vital life process. They are designed to act quickly and dissipate quickly. Most commercial antimicrobials used for treating surfaces do an adequate job of killing bacteria and fungi, although most have a limited range of effectiveness. The ÆGIS technology takes a totally unique approach. It provides an effective initial microbial kill when applied, but, unlike the conventional methods, it also provides long-term control of growth on treated surfaces, often for the life of that surface. The surface itself is modified to make it antimicrobially active. Against what types of bacteria is the ÆGIS Microbe Shield technology effective? The ÆGIS Microbe Shield technology has a mode of action that involves a positive charge and is effective against all bacteria, plus fungus, algae, and mold. A representative list of microbes against which the ÆGIS Microbe Shield technology has been tested may be obtained by contacting our corporate office. Will this technology adversely affect the skin or environment? No. Since the antimicrobial is permanently bound to the surfaces it protects, it does not leach from the fabric to the skin or into the environment. Extensive toxicological testing shows the antimicrobial does not cross the skin barrier. In fact, AEGIS is so save that it is used on baby nappies to prevent nappy rash. What biocide is used? The ÆGIS active ingredient is 3-trimethoxysilylpropyloctade- Does the biocide use a heavy metal? No. The ÆGIS Microbe Shield products do NOT contain any heavy metals. Tin, arsenic, silver and copper are often used in other antimicrobials. Do the ÆGIS products give off gases after application? No. They do not volatilize, dissipate, or leach onto other surfaces or into the environment. The chemistry polymerizes where it is applied and forms a permanent bond that typically lasts for the life of the treated surface. Normal cleaning should not remove the treatment; although it can be abraded away. How is the treatment applied? For Soft Furnishing The ÆGIS products are applied in aqueous solution and can be inserted into almost any wet process during manufacturing at the mill. They can also be applied to finished goods. The antimicrobial is easily integrated into most jet, pad, and batch processes. The antimicrobial is cationic so it mixes well with other cationic and nonionic finishes (most softeners) and performs well in the same bath. For Hard surfaces AEGIS can be treated on any hard surfaces by either fogging, wipe down, soaking or paint rolling on the target substrate. How long does the treatment last? Since the cured antimicrobial is nonvolatile, insoluble, and non-leaching, the treatment should last for the life of the treated surface. The life of a treated surface depends on a number of factors, not the least of which is surface preparation. If you treat a dirty or unstable surface, when the dirt comes off or the surface is disturbed, some of the antimicrobial will be removed with it. Abrasive or caustic (pH>10.5) cleaners will also shorten effective life. Is there a test method to determine if the ÆGIS polymer is present? Yes. The ÆGIS Shield is based on an active ingredient that, in most cases, can be easily detected. A simple method of detection is available to demonstrate the presence or absence of the treatment. Bromophenol Blue (BPB) stain testing clearly shows the presence of the ÆGIS Microbe Shield in a matter of minutes. What tests show that the growth of bacteria has been prevented? Microbiological testing is what establishes the baseline standard that is used to give the BPB analytical procedure its validity for use as a QA and QC tool. ÆGIS has over 25 years experience in performing extensive microbiological tests such as bacterial retrievals, fungal growth tests (AATCC 30, ASTM G-21) and bacterial growth tests (AATCC 100, ASTM 2149-01). We have a long history of bacterial and fungal testing on many products including shoe linings, leather, socks, carpet and building products. Specific studies are available on our web site or you may contact a sales representative. Why are the ÆGIS antimicrobial products so durable? Because of their exceptional chemical bond (a covalent bond) the bonded polymer is neither soluble nor volatile. The unique bond results in the ÆGIS antimicrobial polymer becoming an integral part of the substrate. Will its use result in 'super bacteria'? No. Adaptation studies show that microbes do not adapt to the ÆGIS Microbe Shield and there has been no 'Zone of Inhibition' develops or reported for the last 30 years.
