Halo active aromatic sulfonamide organic compounds and uses therefor
View Patent ↗Aromatic N-halosulfonamide organic compounds have been known for over one hundred years. The ability of these compounds to release active halogen ions has been utilized in a range of biocidal and fungicidal applications. This disclosure deals with the use of halo active aromatic sulfonamide organic compounds as odor control and/or biocidal agents in a cleaning solution for use with bovines and other dairy animals.
