The Importance of Residual Efficacy

Residual efficacy is the residual microbiocidal or antimicrobial effectiveness of the disinfectant when it is applied on surfaces.
It measures the ability of the disinfectant to deactivate microbes. Our Protectus Range has undergone extensive testing to measure its effectiveness in not only destroying microbes but also in inhibiting the growth of microbes long after it has dried.

The Solution?

Our core technology has been developed from years of experience and expertise and result in a unique, patented formulation that enables the ProtectUs range to offer the most unique set of benefits in our industry.

RBTs ProtectUs range significantly reduces the chance of infection AND can reduce the time and cost involved in staying protected. Protectus Ultimate™ & Protectus Viridis™ can be applied to a vast range of environments as a disruptive solution to viruses, bacteria and fungi providing effective disinfection in medical & healthcare, food & drink, animal & pet welfare, professional cleaning and many more industries.

Clinically Proven

RBT solutions are rigorously tested against all relevant testing protocols including EN1276, EN13697, EN1650, Residual efficacy, Taint test, EN14476 viruses, EN1500, biofilm removal and Halal approved at leading independent laboratories.

Besides our in-house laboratories, clinical testing on our products have also been done at independent laboratories in the UK and Germany. These include the Campden BRI Laboratory (UK), the Blutest Laboratory (UK), the Dr Brill and Dr Steinmann Laboratory (Germany), and the Center of Virus and Vaccine Research, Sunway University (Malaysia).

At RBT, we know that testing in the lab and testing in real world environments are both critically important. That is why we have many use case studies where the products were used by childcare centres, dentists and medical clinics.

Meeting Stringent International And Local Requirements

RBT solutions have met the stringent requirements set by the European EN Standards, which evaluate the efficacy of disinfectants against microbes. Through independent testing, Protectus Viridis™ & Ultimate have been proven to have high antimicrobial efficacy, long residual efficacy and is capable of eliminating a broad spectrum of harmful microorganisms.

Field Testing By Established Research Institutions

Our partners at SurfaceTech have also engaged on a consulting basis, established research laboratories including the Center of Virus and Vaccine Research of Sunway University (Malaysia), and the University of South Africa to validate our test results and verify the efficacy of RBT products in live settings with our local and international clients.

Our Partners in Malaysia have an ongoing consulting agreement with the Center of Virus and Vaccine Research of Sunway University to independently verify our testing claims and to conduct ongoing testing procedures for existing and prospective clients in various industries and sectors. Protectus Viridis™ products have been successfully tested in childcare and dental settings on a whole hosts of pathogens, including micro-organisms (commonly associated with HAIs) isolated from hospitals – such as Methicilin Resistant Staphylococcus aureus (MRSA), E. coli and Pseudomonas aeruginosa – under local conditions.

Effective Log Reduction Against A Broad Spectrum Of Microbes

Log reduction is the extent to which the disinfectant is capable of reducing the number of microbes on a surface. A 4-log and 5-log reduction means a disinfectant is able to reduce the number of microbes by 10,000-fold and 100,000-fold respectively after it has been applied to a surface. In other words, it is able to kill 99.999% (4-log reduction) of microbes and 99.9999% (5-log reduction) of viruses.

Protectus Ultimate™ & Protectus Viridis™ have been tested to be effective to perform at log 4-5 reductions in killing pathogens, over a 24-hour period, with 8 wear cycles, on surfaces. This means that after applying on surfaces with Protectus Viridis™, it is able to kill up to 99.999% of microbes on the surfaces and continues to prevent pathogens from proliferating or re-contaminating for up to 24 hours or up to 8 wear cycles.

Our products have been tested independently and
are effective against a broad
spectrum of microbes, including:

  • Staphylococcus aureus
  • Escherichia coli
  • Enterococcus hirae
  • Pseudomonas aeruginosa
  • Listeria monocytogenes
  • Candida albicans
  • Murine norovirus
  • Mycobacterium terrae
  • EV-A71
  • DENV
  • Vaccinia virus
  • Salmonella typhimurium
  • Yersinia enterocolitica
