  • Publication number: 20200305435
    Abstract: A composition having biocidal properties is disclosed. The composition includes a first biocide that synergistically operates with a second biocide to destroy or inhibit the growth of at least one microorganism. The first biocide comprises a quaternary ammonium salt. The second biocide, on the other hand, may comprise a biguanide. The composition is particularly well suited for use in disinfectant products and for use as a preservative.
