EPA Releases Interim Efficacy Guidance and Test Methods for Disinfection of Soft Surfaces

Released on December 21, 2022

Today, the U.S. Environmental Protection Agency (EPA) is issuing for public comment its interim efficacy guidance and test methods for registering products used to kill viruses and bacteria in clinical and institutional settings on soft surfaces such as upholstery, mattress covers, and privacy curtains.

Currently, most EPA-registered liquid-based antimicrobial products, including those on EPA’s list of disinfectants effective against SARS-CoV-2 (List N), are registered for use on hard, non-porous surfaces. Guidance for claims for carpet, rugs, frequently laundered textiles, mattresses, pillows, and upholstered furniture is found in 810.2400 Disinfectants and Sanitizers for Use on Fabrics and Textiles. This new guidance covers test methods and performance standards for disinfection of surfaces (e.g., non-clothing fabrics, textiles, and upholstery that may be laundered on an infrequent basis) not covered under 810.2400.

With the increased interest in the availability of antimicrobial products, EPA’s interim guidance outlines how soft-surface bactericidal and virucidal claims may be added to products that also demonstrate efficacy against specific bacteria and viruses on hard, non-porous surfaces. These products may be used for soft or porous surfaces, particularly in high-traffic, non-residential settings, including hospitals, schools and office buildings.

EPA's interim guidance and methods are available for public comment for 30 days at docket number EPA-HQ-OPP-2022-0337 at www.regulations.gov. For information on how to submit applications for efficacy claims, see EPA’s website.
