Abstract

An cleaning composition loaded on a cleaning wipe having improved biocidal release from the cleaning wipe. The cleaning composition includes a cationic biocide, a biocide release agent and water. The cationic biocide release agent has an ionic strength in the cleaning composition of at least about 5×10⁻³ mol/l.

Claims

1. A hard surface cleaning composition adapted to be loaded on a cleaning wipe comprising about 0.05-5 eight percent cationic biocide as the principal biocide, a cationic biocide release agent having an ionic strength in said cleaning composition of about 1×
