Landmark test result for surface sanitiser validates 24 hour residual efficacy against Coronavirus

  • Product first to have solid evidence of real success in frequent-use areas against viruses – 99.9% reduction after 24 hours
  • News comes as millions of businesses and public spaces prepare to reopen over the next few months
  • Test data provides assurance to organisations aiming to welcome back customers, students, visitors and employees

The Byotrol PLC technical team has successfully developed a test method to verify whether a disinfectant will provide long-lasting protection against viruses in ‘real-life’ conditions, infection prevention company Byotrol plc, announced that its 4-in-1 Multi-purpose Cleaner and Disinfectant has successfully passed the test confirming COVID-19 protection on frequently touched hard surfaces over 24-hours.

It’s the first time that users can have confidence that the disinfectant they have purchased will provide 24-hour protection against coronavirus on frequently-touched hard surfaces in public spaces - from handrails and door handles to worktops, chairs and other areas such as lifts, office environments and hospitality areas.

The new test standard was developed to replicate in-use conditions rather than the perfect laboratory environment typically used in such tests and makes this a significant step forward for the testing of disinfectant products in the future. Byotrol plc, which developed and performed the new test, has a team of virologists and microbiologists who have worked on the project over several months, to ensure that the data is robust, resulting in Byotrol declaring that its 4-in-1 Multi-Purpose Cleaner & Disinfectant is proven to protect against coronavirus on hard surfaces for 24-hours after application.

Professor James Stewart, Chair of Molecular Virology at the University of Liverpool reviewed and verified the results externally. Professor Stewart was keen to comment on what the result means for the future of disinfectants: “The protocol used to generate the data that supports the 24-hour anti-viral claim is scientifically sound.. I have reviewed the report that describes the execution of this test, the data generated and the result obtained on Byotrol’s 4-in-1 product and I can validate the result of a 3.35 Log reduction of this product relative to the water control

In 2014, Byotrol’s technical team, with the help of independent industry experts, established the BSI approved PAS 2424:2014 method for confirming long-lasting protection of disinfectants against bacteria. The PAS 2424:2014 test is currently being reviewed by the CEN Committee for approval as a new European EN test standard.

Whilst other disinfectant manufacturers have claimed long-lasting protection against Coronavirus over the course of the pandemic, this is the first time the claim has been supported by such rigorous test data, performed to a long-lasting test method against a relevant virus – and crucially, using abrasion to mimic the ‘real-life’ conditions of the product in-use.

Byotrol’s 4-in-1’ is fast-acting, it kills 99.99% of bacteria and viruses and offers long-lasting antimicrobial protection for up to 24 hours, even in frequently touched areas. The formula contains the ActizoneTM polymer technology from Solvay, which anchors antimicrobial actives to the surface enabling the residual antimicrobial nature of the formulation. ActizoneTM technology traps antimicrobial actives to form a protective film on surfaces. The actives initially kill 99.99% of bacteria and viruses and go on to deliver 24-hour protection and peace of mind to consumers while ensuring excellent shine and a residue-free finish.

The product is supported by a full microbiological test data pack including efficacy against Coronavirus, Influenza A (H1N1) and Rotavirus in just 60 seconds, tested to UK and European standard test methods. It is compliant with the European Biocidal Products Regulation and can be used safely in a multitude of environments.

The business says that the test results will give its customers and end-users more confidence in which products on the market are proven to be effective.

Rick Hayman, Managing Director of Byotrol’s Professional Sales Division, said: “Many organisations and distribution channels have expressed concern over the mysticism of claims made by suppliers in the disinfection market. This latest test development will provide the necessary assurance to those organisations seeking proof of residual efficacy against viruses and other micro-organisms, whilst protecting their stakeholders as lockdown relaxes in the UK.”

There have been multiple reports of hand sanitisers and other disinfectant products being sold on Amazon, Ebay and by companies at significantly elevated prices, driven by opportunistic profiteering. Trading Standards and the Government has already made statements regarding task forces to crack down on this practice and some countries have set limits on the prices of certain products.

Medimark Scientific takes a moral and ethical approach to pricing and sale of our products and we strongly distance ourselves from any company that would use this crisis for the purposes of profiteering.

Rest assured that the price you pay today is unchanged through this crisis!

Regulatory Impact of Brexit on Medical Devices

Marking of medical devices in accordance with the requirements of European Council Directive 93/42/EEC as amended permits the sale of CE marked product throughout Europe.

Medimark Scientific Limited are certified by Lloyds Register (LR) in the United Kingdom for the manufacture and distribution of CE marked medical device disinfectants throughout Europe. Such certification is denoted by displaying the CE mark and Lloyds Register’s UK notified body number 0088 on the product label.

The impact of the process known as Brexit on CE marked products manufactured by Medimark Scientific is as yet unclear due to the lack of information and planning that is forthcoming from our Government however, there are a number of potential scenarios that are being considered. Any form of Brexit which does not include plans to allow UK Notified Bodies to continue to provide their clients with CE marking services could directly lead to the risk of patients’ lives in the UK and EU. Our Notified Body believes it is therefore extremely likely that the UK Government and the EU Commission will forge a suitable agreement with the EU27 to prevent this from happening.

Worst Case Scenario – No Deal/Hard Brexit

To maintain our ability to place product on the market in the event of a no deal or hard Brexit, we are required to use a European recognised Notified Body. Our UK Notified body has submitted an application to the Dutch Competent Authority (Inspectie Gezondheidszorg en Jeugd, IGJ) for appointment as a Notified Body in the Netherlands. This will enable them to provide identical services to those they currently provide through their UK Notified Body with what is expected to be a reasonably straightforward process.

If the LR application to the Netherlands is not approved in time and in, what they view as the highly unlikely event of a hard Brexit, then they would be unable to provide Notified Body services for products entering the EU27 markets and as such, current LR issues EC certificates would cease to be valid with effect from the withdrawal date (1st November 2019 00:00 hrs CET). The implications of such a situation are unprecedented.

Therefore, in the worst-case scenario of no deal or a hard Brexit our current EC Certificate will become void on the date at which the UK leaves the EU (31st October 2019). This will result in us not being able to place product on the market until such times as Medimark Scientific Ltd has an EC Certificate from a European Notified Body.

Soft Brexit

In the event that the proposed deal is struck, it is our understanding that a ‘Soft Brexit’ will include an implementation period in which the conformity assessment regime remains unchanged. One possible outcome is that the mutual recognition of Notified Bodies will be included in the proposed transition agreement, covering the period until December 2020 and may also include the possibility of a permanent mutual recognition scheme forming part of the final agreement however, this is yet to be seen. In such a scenario, our existing EC certificate, issued by LR (UK) will continue to be recognised in the EU, in at least the short term, allowing for a period of time to understand what new arrangements are required (if any).

What this could mean for you?

We are continuously liaising with our Notified Body and Government Departments to understand the situation as it unfolds and are putting measures in place to mitigate risks where possible. Existing product that is already in the market, including stock which has been sold to distributors, will continue to be supported under the original CE mark. We feel it necessary to warn customers, particularly those outside of the UK that there may be a period of time whereby Medimark Limited may not be able to directly supply products under our existing CE mark and there may be a delay in obtaining a new CE mark from which is directly linked to the approval of Lloyds Register in the Netherlands and the administration transfer to them. As such we are advising customers to review their current stock levels and order as appropriate in advance of the 1st November 2019 00:00 deadline.

We will endeavor to keep all customers informed of updates as and when they are available. In the meantime, the management team at Medimark Scientific Ltd are on hand to answer any questions that customers may have.

Acquisition of UK infection control company Medimark Scientific Limited

Byotrol plc, the AIM listed anti-microbial hygiene company, is pleased to announce the acquisition of Medimark Scientific Limited (“Medimark”) a leading provider of biocide-based infection control products into the animal and human healthcare markets.

Medimark is a profitable and growing business which has a broad sales, marketing and distribution expertise. Medimark sells infection control products used on surfaces, instruments and hands for the Animal Health, Human Health, Laboratory, Environment and Retail markets. The company is based in Sevenoaks, Kent, and is ISO9001 quality registered with supporting registration under the Medical Device Directive

There is an existing and long-standing relationship already in place between the two companies – Byotrol is currently a white label supplier of hand sanitisers to Medimark, which it sells under its Esense brand.


  • Immediately provides Byotrol with greater scale than could be achieved through current rates of organic growth. Medimark is profitable and cash generative and fits extremely well with Byotrol’s existing products and technology.
  • Highly complementary acquisition, offering extensive sales, marketing and distribution expertise in Byotrol’s core markets. Specific complementary with Byotrol’s Professional and Petcare businesses with significant synergies expected over time, including: enhanced distribution of Byotrol technologies to Medimark customers, in the UK and overseas, boosting economies of scale, distribution and market segment expertise, highly experienced, well-connected and resilient sales team and sales support and introduction of stronger disinfectant technologies to Byotrol portfolio including a proprietary sporicidal formulation
  • Doubles workforce, creating immediate critical mass with cost synergies available from bringing Medimark technical work in house.
  • Executive management staying with the combined business for the earnout and beyond, with incentives closely aligned with Byotrol shareholders.

Commenting on the
acquisition, John Langlands, Byotrol Chairman, said:

“We are delighted to have concluded the acquisition of Medimark and we welcome its directors, employees, customers and stakeholders to Byotrol. The fit between the two companies is remarkably strong with Medimark’s excellent sales and marketing capabilities dovetailing very well with our technical expertise. We also see more opportunities to take the combined group’s infection control products into consumer markets. Our enlarged operations will now be offering cutting-edge infection control products to more customers in our jointly-targeted markets with improved propositions. We have a strong balance sheet and are confident that the combination of the two companies will bring Byotrol to critical mass with the resources to deliver sustained growth and profitability.“

Rick Hayman, the MD and
major shareholder of Medimark, added:

“Joining forces with Byotrol is a very exciting step forward for the Medimark team, enabling us to take our business to a new level. With their technical expertise and our combined commercial and sales experience skills, we see the two companies as an excellent fit. We very much look forward to pursuing the market opportunities together with the Byotrol team.”


Where “DEFRA APPROVAL” Is Required

The use of a “DEFRA APPROVED” product and its relevance to companion animal health organisations has often been confusing and exploited by certain competitors to sell their products.

The DEFRA protocol is established to identify products that can be used in the event of a notifiable disease outbreak under one of the five orders, being Diseases of General Orders, Poultry Order, Swine Vesicular Disease, Foot and Mouth Disease and TB. However, a “DEFRA Approved” product is ONLY required in the event an outbreak of one of such diseases and even then a recommended disinfectant under the relevant order should be used. Generally, products on the Approved Disinfectants list are designed for agricultural environments and designed to work in cold and extremely soiled environments, unlike most companion animal establishments.

Some commonly available companion animal disinfectants do have DEFRA Approval, but we believe that it is impractical to provide DEFRA Approval for all fragrance varieties and all disease orders, since products of our type (made for safe use around animals) generally pass at only high dilutions under DEFRA testing, such as 1:2 - 1:10. We regard these dilutions for companion animal health as impractical for several reasons: -
Instead and where ther is the rarity of a Notifiable Disease Outbreak, we recommend a product that is specially designed for such application. ANIGENE NaDCC has been tested across the majority of Notifiable Diseases at a dilution of between 1:317 and 1:953, with General Orders at 1:360. Additionally, this product is effective against Giardia Lambliaand is recommended as a periodic Deep Clean product or as an economic disinfectant in the event of a notifiable disease outbreak.

  • Using a product at 1:2 - 1:10 (30% - 10%) disinfectant to water ratio would be very expensive
  • Using a product at these dilutions would make cleaning very difficult
  • exceptional foam levels, residue build up, sticky floors, excessive rinsing required
  • There is a potential risk to staff and animals from contact with concentrated chemicals




Join the war against MRSA, E.coli, Coronavirus, Hepatitis, etc. We have opportunities for companies or business motivated individuals to develop exclusive Regional Distributorships and agents for high level infection control and hygiene products into the Human Health, Environmental and Animal Health sectors. We are a UK manufacturing company with over twenty years successful track record and recognised branding in the industry.
