EPA Reg. 10324-154Synergy Four Disinfectant
Quat disinfectant, cleaner, and deodorizer — four jobs in one concentrate
Synergy Four Disinfectant
Synergy Four Disinfectant is a concentrated, neutral pH quaternary-ammonium disinfectant, cleaner, and deodorizer in one. Part of the Synergy Four family — the same proven chemistry as the Aerosol and Deodorant in the line, formulated for mop-bucket and spray-bottle dilution.
Built for facilities that need to disinfect AND deodorize in one step — hospitals, nursing homes, schools, daycare centers, veterinary clinics, and any institutional or industrial setting. When used per label directions, it's a one-step hospital-use disinfectant that is bactericidal, virucidal, fungicidal, and mildewstatic.
What makes Synergy Four Disinfectant different
- One-step hospital-use disinfectant. Cleans, disinfects, deodorizes, and inhibits mildew in a single application on hard, non-porous, non-food contact surfaces.
- SARS-CoV-2 in 2 minutes. Effective against COVID-19, plus HIV-1, Hepatitis B/C, influenza A (H1N1/H3N2), RSV, and coronaviruses at 2 oz/gal.
- Broad-spectrum bactericidal. Effective against MRSA, VRE, VISA, E. coli (including O157:H7, ESBL, and antibiotic-resistant strains), Salmonella, Listeria monocytogenes, Pseudomonas, and 40+ other organisms.
- Animal / veterinary claims. Effective against Canine Distemper, Feline Picornavirus, Canine Coronavirus, Avian Influenza H5N1/H3N2, and Swine H1N1 at 2 oz/gal. Canine Parvovirus and Rabies at 9 oz/gal.
- Family of formats. Pair with Synergy Four Aerosol and Deodorant for matching Fresh Linen fragrance across high-touch and ambient spaces.

Apply to pre-cleaned surface
Apply to a pre-cleaned hard non-porous surface with mop, sponge, cloth, or sprayer. Heavily soiled surfaces should be cleaned first.
