Introducing RBT Viridis

Our missionTo bring about a change in how we protect both us and our world

Residual Barrier Technology Limited (RBT UK) developed a range of disinfectants and applications that are clinically tested to perform better, protect longer, less harmful, save time and money in application.

RBT has developed a disinfectant solution with 3 levels of protection:• Less harmful• Provides up to to 99.999% effectiveness• Residual protection

Our solution

Introduction• RBT Viridis is a water-based, organic and biodegradable product with very effective microbiocidal efficacy on a broad

spectrum of bacteria, viruses and yeasts.

• The major differentiation of Viridis as compared to other disinfectants is the unique RBT technology that enables

the residual efficacy to be much longer lasting than traditional alcohol based disinfectants (up to 4 hours on hands and 24

hours on hard surfaces).

• Viridis tested against highest EN standards in UK/EU and registered under German BAuA. Viridis products have also been

successfully tested in various childcare and dental settings on microorganisms isolated on surfaces as well as on

several antibiotic resistant bacteria isolated from Malaysian hospitals.

• These tests were carried out by the independent laboratory of Sunway University headed by Distinguished Prof Poh Chit Laa,

(Head of the Centre of Virus & Vaccine Research). Prof Poh* is a leading microbiologist / virologist in the region.

* She has published over 100-ISI cited papers and is on the Editorial Board of the Journal of Bioscience and Bioengineering, published by the Society of Biotechnology, Japan.She is also the leading expert in the world on Enterovirus 71.

What is RBT Viridis

• Unique disinfection formulation to maximise efficacy

and user acceptability

• Broad spectrum efficacy

• Non-corrosive to surface materials

• Water-based, biodegradable ingredients

• Continues to kill pathogens when dried using residual

barrier technology

9

• High antimicrobial efficacy

• Long lasting residual barrier protection

• Less harmful & biodegradable

10

Antimicrobial efficacy

Synergetic, water-based mix of:

1. Organic acids

2. Solvent and preservative

3. Surfactants

Each ingredient by itself is bacteriostatic (preservative) or weakly microbial.

Only by combination in the right ratio, all ingredients work together and become highly effective against bacteria, yeast and viruses.

Enterovirus (EV-A71) and Dengue virus (DENV)

Viridis was proven to be effective in killing Enterovirus (EV-A71) and Dengue virus (DENV) in a study conducted by Sunway University. Viridis was also found to be effective in protecting mammal cells from infection of these viruses.

• High antimicrobial efficacy

• Long lasting residual barrier protection

• Less harmful & biodegradable

13

Residual protection

Ingredients are kept on surface in their active form after

drying:

• Actives need to be stable, stay in their right ratio and be able to

rehydrate upon recontamination

• No covalent interaction with the surface

Our technology

• Actives preserved in micelles formed by surfactants

• Actives are not easily removed from surface by mechanical action

• Minimal surface modification

• Easily rinsed off

Residual protectionTesting done according to established industry protocol:

• Dry disinfectant on test surface

• Incubation under ambient conditions for 2h-24h

• Treatment with different amount of wear cycles:

• Dry cycle: Polyester cloth wiped over test surface with defined force

• Wet cycle: Damp polyester cloth wiped over test surface

• Inoculation with suspension containing test organism

• Sampling of surviving organisms and determination of reduction in viable cells

15

• High antimicrobial efficacy

• Long lasting residual barrier protection

• Less harmful & biodegradable

Why biodegradable?

OECD 301: Test Guideline describing methods that permit the screening of chemicals for ready biodegradability in an aerobic aqueous medium.

Recent times – COVID19Viridis has a proven track record against similar enveloped virus as well as other non-

enveloped virus where it is 100% effective in killing or inhibiting; such as HFMD EV-A71 (non-

enveloped) and DENV (enveloped).

In a lab test conducted at Sunway University, under Prof Poh, 5% Viridis was able to inhibit EV-

A71 in 5 minutes whereas it took 10% Chlorox (highly toxic) to be effective in 60 minutes. EV-

A71 is typically a virus that can survive up to 7 days on surfaces and the current COVID2019

has been reported to exhibit similar survivability rate on surfaces.

18

The Viridis formulation therefore has been proven to inhibit viruses that have the characteristic of survivability on surfaces.

Viridis has been tested to be effective to perform at V-log 4-5 (99.999%) in killing pathogens, over a 24 hour period, with 8 wear cycles, on surfaces.

Instructions to use

1. Ensure area is clean and all dirt remove before Viridi disinfectant is applied.

2. Apply Ready To Use (RTU) solution using spray or fogging from a distance of

approximately 30cm from the surface or equipment

3. The surface or equipment to be treated should be evenly and lightly wetted. Avoid

drenching the equipment with excessive product. There should not be any running

of droplets or drips from the treated areas. Viridis disinfectant is water based and

non hazardous and should be allowed to air dry.

4. Once air-dried, the treated area will be effectively disinfected following a contact

time of 5 minutes.

5. Re-apply on high traffic areas such as touch screens.
