Abstract
A process for enhancing oral hygiene by reducing oral microflora and for inhibiting the formation of dental plaque by applying, to the oral cavity, a composition containing PA1 (a) 0.1 to 40 parts, by weight, of a higher alkyl-N-betaine, having the structure ##STR1## wherein N is a higher alkyl group of from 10-18 carbon atoms, and (b) 0.1 to 40 parts, by weight, of a higher alkyl-N, N-dimethylamine, having the structure ##STR2## wherein R is a higher alkyl group of from 10 to 18 carbon atoms, and (c) acid in an amount sufficient to adjust the pH of the composition from 4.5 to 7.5 when measured in an aqueous solution of components (a) and (b) in a orally acceptable carrier.
