Abstract:
1. A method for reducing an abrasivity of a dentifrice composition comprising: a.) an abrasive selected from the group consisting of silica, alumina, alkali metal meta-phosphates b.) an antimicrobial agent; and c.) a phosphoric acid—sodium phosphate, sodium monophosphate, or sodium dibasic phosphate buffer, said method comprising incorporating into said dentifrice composition zinc citrate in an amount sufficient to reduce a dentinal abrasivity of said composition by at least 20% to provide an improved dentifrice composition, wherein said improved dentifrice composition is at least 90% as effective at stain removal as said dentifrice composition wherein the pH of the composition is below about 5.5% and wherein the antimicribial agent is non-cationic.
