K-Quat

A quaternary ammonium (quat) sanitizer is a chemical compound approved by the EPA for sanitizing food contact surfaces in foodservice and food processing environments. Quat sanitizers work by disrupting the cell membranes of bacteria and viruses, killing them on contact when applied at the correct concentration. K-Quat uses a four-chain quaternary ammonium chloride blend that provides broad-spectrum kill against gram-positive and gram-negative bacteria, viruses, and protein-tolerant microorganisms. Chlorine, iodine, and quaternary ammonium are the three chemical sanitizers approved for food contact surface sanitizing under the FDA Food Code.

K-Quat is a no-rinse formula when used as directed on food contact surfaces. After pre-cleaning the surface and applying the diluted K-Quat solution, allow the surface to drain and air dry completely before food contact, no additional rinse is required. This makes quat-based sanitizers like K-Quat more efficient for high-volume food production and commercial kitchen workflows than some other sanitizers that require a final rinse step. Always verify the active concentration with the appropriate test strips before use and follow all EPA label directions.

For standard no-rinse food contact surface sanitizing with K-Quat, dilute 1 ounce of concentrate per gallon of water. For immersion sanitizing in three-compartment sinks or equipment dip tanks, use 1 to 2.67 ounces per 4 gallons of water to achieve a solution of 150 to 400 ppm active quat. Always use the appropriate quaternary ammonium test kit or test strips to verify the solution concentration before use, as both under-concentration and over-concentration affect performance and safety. Follow all EPA-registered label directions for the specific application type.

Yes. Quaternary ammonium sanitizers like K-Quat are one of the three chemical sanitizers approved for three-compartment sink sanitizing in foodservice operations under FDA Food Code guidelines. For three-compartment sink use, immerse pre-cleaned utensils, glassware, dishes, and equipment in a K-Quat solution at 150 to 400 ppm active quat for a minimum of 1 minute, then allow items to drain and air dry without rinsing. Always verify the quat concentration in the sanitizing sink water using appropriate test strips before starting a sanitizing cycle, and change the solution when concentration falls below the minimum effective level.

Quaternary ammonium (quat) sanitizers and chlorine bleach are both FDA-approved for food contact surface sanitizing, but they have different characteristics. Quat sanitizers like K-Quat are odor-free, non-corrosive to most surfaces, and offer residual sanitizing activity, meaning surfaces stay protected longer after application. Bleach-based sanitizers can produce a strong chlorine odor, corrode metals and equipment over time, and lose effectiveness quickly when diluted. Quat sanitizers are generally more stable in solution and more cost-effective at high dilution ratios. However, quat concentration must be tested with the appropriate test kit, as the effective range is narrower than bleach.
