GERMICIDAL COMPOSITIONS CONTAINING HALOGENATED PHTHALALDEHYES, AND METHODS OF USING SUCH COMPOSITIONS FOR DISINFECTION OT STERILIZATION

摘要

Germicidal compositions including a diluent, and a germicidal compound havi ng the formula: <See formula I> wherein X is a halogen, and methods of using such compositions for killing bacteria, disinfection, or sterilization are disclosed. In one aspect, the composition may include a germicidally effective amount of the compound. For example, the composition may include an amount of the compound that is effective to kill at least 1.times.10 6 Mycobacterium terrae bacteria in contact with the composition in less than one hour with a bacteria suspension test at a temperature of 20.degree.C. In another aspect, the compound may have a staining property that is less than that of phthalaldehyde.
