CINCINNATI – Pilot Chemical Corp. announced that through its subsidiary, Mason Chemical Co., it has received EPA acceptance to add an emerging viral pathogen claim to the labels of eight products from the company’s EPA-registered quaternary ammonium compound and active ingredient line, under its Maquat® and Maguard® brands.

The National Institute of Allergy and Infectious Diseases defines emerging viral pathogens as pathogens “that have newly appeared in a population or have existed but are rapidly increasing in incidence or geographic range.” In the case of SARS-CoV-2, the product must have the emerging viral pathogen language on the label and be effective against a harder-to-kill virus than SARS-CoV-2.

“Meeting the EPA’s criteria for effectiveness against emerging viral pathogens enables our customers to make off-label claims that their products can fight the virus that causes COVID-19 and future threats that may emerge,” said Richard Rehg, Vice President of Commercial, Pilot Chemical Co. “Our team has been working hard to bring this to fruition and help our customers offer effective formulated products to meet rapidly changing market needs.”

This represents the first group of Pilot products submitted for emerging viral pathogen claims, with plans for additional future submittals.
