PURPOSE: To more effectively inhibit action of saliva enzyme on anticalculus agent of polyphosphoric acid by using a non-polycarboxylate polymer. n CONSTITUTION: This oral composition such as toothpaste (including gel or cream), mouthwash, lozenge, chewing gum or tooth powder comprises a calculus- inhibiting amount of a linear molecularly dehydrated polyphosphate salt and a synthetic polymeric vinyl phosphate as inhibitor of enzymatic hydrolysis of the polyphosphate salt in saliva. A fluorine ion-providing source may also be present to further inhibit enzymatic hydrolysis of the polyphosphate salt. n COPYRIGHT: (C)1992,JPO |
