Articles are treated with a reduced amount of a halo active aromatic sulfonamide compound of Formula (I):wherein R1, R2, R3, R4, and R5 are independently selected from hydrogen, COOR′, CON(R″)2, alkoxy, CN, NO2, SO3R″, halogen, substituted or unsubstituted phenyl, sulfonamide, halosulfonamide, and substituted or unsubstituted C1-C12 alkyl； R′ is hydrogen, an alkali metal, an alkaline earth metal, substituted C1-C12 alkyl, or unsubstituted C1-C12 alkyl； and R″ is hydrogen or substituted or unsubstituted C1-C12 alkyl, where the two R″ groups in CON(R″)2 may be independently selected； X is halogen； M is an alkali or alkaline earth metal； and n is the number of water molecules per molecule of the sulfonamide compound. The compound effectively suppresses odors pre-use, in use, and post-use for extended periods of time.
