Germicidal compositions including a phthalaldehyde and methods of using suchncompositions for killing bacteria, disinfection, or sterilization, are disclosed. In onenaspect, a germicidal composition may include a diluent, a germicidal compound, such asnphthalaldehyde, and an amount of isophthalaldehyde to enhance the germicidal efficacynof the germicidal compound. In the case of phthalaldehyde, the composition may have anstaining property that is less than a staining property of a composition consistingnessentially of phthalaldehyde diluted to the same concentration. In another aspect, thencomposition may further include an amount of terephthalaldehyde to enhance thengermicidal efficacy of the phthalaldehyde. In yet another aspect, a germicidalncomposition may include a diluent, phthalaldehyde, and a material such asnisophthalaldehyde, terephthalaldehyde, or a combination of isophthalaldehyde andnterephthalaldehyde, in order to reduce a staining property of the phthalaldehyde. |
