Is my disinfectant effective against the novel coronavirus?

The novel coronavirus designated SARS-CoV-2 (also referred to as COVID-19, the name of the illness it causes) first appeared in late 2019 in Wuhan, China.  As it spreads rapidly throughout the world, the novel coronavirus is testing the capacity of health systems in many countries.  Proper disinfection of shared spaces is an important aspect of containing the spread of the virus, along with social distancing measures.  But how can you ensure that the disinfectant you are using is effective against coronavirus?

The disinfectant certification process

The United States Environmental Protection Agency (EPA) is the primary legal authority in the US for regulating disinfectants, which are technically classified as a form of pesticide.  In order to be approved by EPA, a disinfectant must undergo substantial lab testing to verify its efficacy against common pathogens as well as safety for use around people.  Each "kill claim" requires additional testing at considerable time and expense, so many disinfectants are certified as effective against certain subsets of pathogens.

Understanding disinfectant registration

Due to the complicated nature of certification, the active ingredients in most disinfectants are manufactured by a small number of major suppliers.  Approved ingredients are then sub-registered to other manufactures, including Maintex.  Sub-registered products require the same rigorous quality control and labeling requirements as master registrations, and have the same kill claims and contact times.

All Maintex disinfectants are manufactured with EPA-approved active ingredients.

Our most popular concentrated disinfectant for novel coronavirus is CItra Cide, which has a one minute contact time against Human coronavirus.  Turbo Kill is our ready-to-use disinfectant that is effective against Human coronavirus with a two minute contact time.  For disinfecting food contact surfaces, use Sani-Cide Plus with a one minute contact time.  Other Maintex disinfectants are also effective against Human coronavirus and eligible under the EPA Emerging Viral Pathogen Program.  Check with your Maintex sales consultant for more information.


 

Verifying a disinfectant is approved for novel coronavirus

Your supplier of disinfectant should provide an efficacy information sheet that lists all the kill claims, contact times, and testing procedures.  The most basic check is to look for a claim for "Human coronavirus."  This claim technically refers to previous strains of coronavirus including SARS and MERS.

For newer threats like the novel coronavirus, the EPA uses a certification regime called the Emerging Viral Pathogen Program.  This program certifies existing disinfectants based on preliminary data.  The EPA has released a list of disinfectants certified under the program in a document referred to as List N (PDF).

On the label of each disinfectant as well as on the specification sheet and efficacy information sheet is a registration number such as this one for Maintex Citra Cide: EPA Reg No. 47371-131-6885.  The first two number groupings correspond to the master registration for the active ingredient in the product.  The third number grouping indicates the Maintex sub-registration. Looking up the registration EPA List N displays the following information for Citra Cide under the master registration:

Registration Number Product Name Company Formulation Type
47371-131 HWS-64 H&S CHEMICALS DIVISION OF LONZA, LLC DILUTABLE

Clicking on the registration number on the digital version of EPA List N leads to the EPA-approved label and efficacy claims.

The Clean Up

Frequent disinfecting is an important component of reducing the speed and spread of novel coronavirus.  Make sure you are using a disinfectant that is approved for coronavirus and follow all instructions for dilution and contact time.  Practice good hygiene including social distancing measures to help reduce the spread of this dangerous new threat.
