Abstract
Abstract An oral preparation comprising a dentally acceptable oral vehicle and dispersed therein a cationic antibacterial agent in amount of about 0.01-5% by weight based on the cationic portion thereof and about 0.05-5% by weight of an anionic phosphate ester surface active agent comprising a mixture of monoester of the formula ##STR1## wherein R is an alkyl group of 10-20 carbon atoms, n an integer from 1-6 and M is selected from the group consisting of hydrogen, alkali metal and ammonium, said oral preparation having a pH of at least 6.
