Abstract
Abstract An oral composition such as a toothpaste (including gel or cream), mouthwash, lozenge, chewing gum or tooth powder containing a calculus-inhibiting amount of a linear molecularly dehydrated polyphosphate salt and, to inhibit enzymatic hydrolysis of said polyphosphate salt in saliva, a combination of a fluoride ion-providing source and a synthetic linear polymeric polycarboxylate.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
123 words
In a method of inhibiting dental calculus by applying to the teeth a mouthwash composition containing in an orally acceptable vehicle one or a mixture of linear molecularly dehydrated polyphosphate salts selected from the group consisting of water soluble alkali metal pyrophosphates, tripolyphosphates and hexametaphosphates as essential anticalculus agents, and an amount of a fluoride ion source sufficient to supply about 25 ppm to about 2,000 ppm of fluoride ion, the improvement wherein salivary hydrolysis of P--O--P bonds in said polyphosphate salt by phosphatase enzymes is inhibited consisting essentially of including in said composition an effective inhibiting amount therefor within the range of about 0.05 to about 3 wt. % of a water soluble alkali metal or ammonium synthetic anionic linear polymeric polycarboxylate.
Claim 2
Dependent Claim
123 words
In a method of inhibiting dental calculus by applying to the teeth a mouthwash composition containing in an orally acceptable vehicle one or a mixture of linear molecularly dehydrated polyphosphate salts selected from the group consisting of water soluble alkali metal pyrophosphates, tripolyphosphates and hexametaphosphates as essential anticalculus agents, and an amount of a fluoride ion source sufficient to supply about 25 ppm to about 2,000 ppm of fluoride ion, the improvement wherein salivary hydrolysis of P--O--P bonds in said polyphosphate salt by phosphatase enzymes is inhibited consisting essentially of including in said composition an effective inhibiting amount therefor within the range of about 0.05 to about 3 wt. % of a water soluble alkali metal or ammonium synthetic anionic linear polymeric polycarboxylate.
