Abstract
Official abstract text for this publication.
The invention includes a dentifrice composition that comprises a zinc ion source, a polyphosphate ion source, an anethole, and a silica. The silica has a mean particle size of about 5 to about 12 microns, an Einlehner hardness of about 1 to about 20, and an oil absorption of about 40 to less than about 100 cc/100 g. The composition contains zinc ions and polyphosphate ions in a weight ratio of about 0.1:1 to about 10:1 and has a RDA value of about 100 to about 200 and a PCR value of about 75 to about 110. Related methods are also included.
