Goldshield®’s persistent residual antimicrobial barrier protection technology
- The microbe lands on the treated surface
- The microbe is then pulled onto the molecule by strong electrostatic forces
- The microbe is then pierced and killed
- The analogy is “a bed of molecular nails”
Goldshield ® ’s technology forms a covalent bond which allows it to remain affixed to any hard or soft surface. The surface is then positively charged generated by a nitrogen molecule, which pulls in negatively charged microbes. Through a long chain carbon, this unique assembly penetrates the cytoplasmic membrane physically stabbing the cell releasing ions, denaturing proteins and causing cytoplasm to leak so the cell is then destroyed. This renders the microbe dead and incapable of any adaption.
Goldshield ® uses a technology that not only cleans and disinfects any surface but also protects it from microbes that land on the treated surface once it is dry.
Extensive clinical trials have shown the product will remain active depending on the product and surface treated from 24 hours to 14 days. For many years cleaning and disinfection has relied upon old technologies that have failed to evolve and keep pace with microorganisms that are becoming ever more difficult to treat.
The need for new products that are safe to use, sustainable and are as environmentally friendly as possible has never been greater, Goldshield ® fits this need.
Goldshield® is an innovative solution to reduce the risk of cross-infection, providing a more effective solution that can be easily implemented without causing any business interruption whatsoever.
Goldshield ® is a silicone based polymer that for many years was used in the treatment of textiles to provide both hydrophobic and antimicrobial properties. Our R&D team were able to adapt this technology to provide a water based solution and a molecule capable of forming a covalent bond with hard and soft surfaces. This meant that we now have a biocidal product capable of being used on hard and soft surfaces that provides a durable antimicrobial mono-molecular layer protecting the surface for extended periods.
Why is this of benefit?
Disinfectants of which there are many, are important to control pathogenic or harmful microorganisms as if there are any on a surface which have the potential of causing infection, removing them by cleaning and killing them by disinfection minimises that risk. Many products contain both detergent and disinfectant and are termed sanitisers. Products containing powerful agents such as chlorine or more recently chlorine dioxide, have excellent microbicidal properties but can be damaging to surfaces and can have health & safety issues depending on their concentration.
When these products are applied they remove the pathogen but only at that point in time if the source of the pathogen remains the surface will re-contaminate after approximately 2 hours and with other potentially harmful (and non-harmful) microorganisms. Goldshield ® is not only microbicidal at point of use but also carry’s on protecting the surface, to a level minimising the risk of cross-contamination. Other disinfectants cannot provide this extended antimicrobial activity
Goldshield ® and routine cleaning processes
Goldshield ® does not replace cleaning as this remains an important part of the process and as an acknowledgement of this we have a sanitiser in our range that both cleans and disinfects. A surface has to be visibly clean before the application of Goldshield ® . The reason cleaning is important is that during the course of the day surfaces become “contaminated” and need to be cleaned to remove any solids and for aesthetic reasons. Moreover, if surfaces were not cleaned regularly preferably with microfiber and normal detergent, soiling such as body fat (the “smudge” we see on glass) will build up and both shield and provide nutrients for microorganisms held within to grow and develop.
Goldshield ® ’s covalent bonding means that the product remains active and even if the treated surface is cleaned by physical and even chemical action. Goldshield ® has a product that:
- Is not removed by routine cleaning
- Enhances cleaning
- Provides a surface that is microbiologically clean for between 24 hours and 14 days depending on the product used and the surface to which it is applied.
Goldshield ® is a product that:
- Provides an anti-microbial surface once dry
- Is a broad spectrum biocide
- Is Water based
- Covalently bonds to any surface making it difficult to remove
- Microbiologically protects surfaces over long periods of time
- Is safe and simple to use
- The analogy is “a bed of molecular nails ”
Goldshield ® ’s unique technology differs to other technologies in that it not only kills microorganisms but also leaves a residual layer on any surface once dry. Most other formulations contain quaternary ammonium compounds (QAC) as the main biocidal active, which is not capable of leaving an antimicrobial barrier once dry.
In the environment, residual activity is important because even though after disinfection, the levels of environmental bacteria are reduced, they soon recover as the surface is re-seeded from the air, people and animals shedding microorganisms and touching surfaces and other sources.
Goldshield ® provides a protective layer that has been shown in numerous tests to remain for periods in excess of 24 hours and 14 days depending on the product used and the surface to which it is applied. Also, because Goldshield ® has a unique covalent bond, it is able to remain on the surface even if it is subsequently cleaned with normal detergents after application as cleaning is important to remove soils such as dirt and body fat. This is represented on the graph above, which is a visual representation to show the principle. The numbers of bacteria and levels of kill will vary depending on the environment.
Goldshield ® ’s ability to create this protective layer after disinfection, reduces the potential for cross-contamination/infection of potentially harmful pathogens in all areas of application in our industry sectors. This will create a safer environment in a world where we are seeing more and more antibiotic resistant strains of bacteria and viral pandemics. Goldshield ® ’s technology therefore provides a safer environment by providing a protective shield, wherever it is applied giving confidence that surfaces remain hygienic for days after application.
