Users in general and children in particular who wash contaminated hands before meals with slow-acting antimicrobial compositions for relatively short time are at risk of contracting diseases. Further, many antimicrobial actives in addition to abrasives are included in oral care compositions like dentifrices but these actives generally require several minutes if not house before effective antimicrobial action is effected. People often brush their teeth or rinse their mouth for very short period of time e.g. cleaning of the order of 1 minute or less thus making such compositions quite ineffective in providing the desired benefit.
