Abstract
A solid cleaning composition, the composition including: one or more anionic surfactants, wherein the one or more anionic surfactants constitute 40 wt. % to 90 wt. % of the composition; a cationic biocide, wherein the cationic biocide constitute 0.0001 wt. % to 2 wt. % of the composition; and one or more humectants; wherein the one or more humectants constitute 0.03 wt. % to 35 wt. % of the compositions, the cationic biocide retaining its biocidal activity as demonstrated by a reduction of at least 1.0 log 10 in a standard hand wash test.
