Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 121 words
An oral composition comprising: (a) from about 0% to about 70% by weight of a dental abrasive compatible with pyrophosphate ions and fluoride ions; (b) an amount of fluoride ion source sufficient to supply from about 50 ppm to about 3,500 ppm of fluoride ions; (c) an amount of at least one pyrophosphate source sufficient to provide at least 1.5% ((P207)-4; and (d) from about 2% to about 95% water; wherein the pH of said composition is from about 6.0 to about 10.0, said composition contains sodium ions and potassium ions in a ratio of sodium ions to potassium ions of from about 0.2:1 to about 5.7:1 and said compositions contain not more than about 0.5% total dialkali metal pyrophosphate sources.
Claim 2
Dependent Claim 121 words
An oral composition comprising: (a) from about 0% to about 70% by weight of a dental abrasive compatible with pyrophosphate ions and fluoride ions; (b) an amount of fluoride ion source sufficient to supply from about 50 ppm to about 3,500 ppm of fluoride ions; (c) an amount of at least one pyrophosphate source sufficient to provide at least 1.5% ((P207)-4; and (d) from about 2% to about 95% water; wherein the pH of said composition is from about 6.0 to about 10.0, said composition contains sodium ions and potassium ions in a ratio of sodium ions to potassium ions of from about 0.2:1 to about 5.7:1 and said compositions contain not more than about 0.5% total dialkali metal pyrophosphate sources.
Claim 3
Dependent Claim 23 words
The composition of Claim 1 wherein said ratio of said sodium ions to said potassium ions is from about 0.4:1 to about 2.6:1.
Claim 4
Dependent Claim 33 words
The composition of Claim 2 in the form of a dentifrice wherein the pyrophosphate source is selected from the group consisting of dialkali metal pyrophosphate salts, tetraalkali metal pyrophosphate salts and mixtures thereof.
Claim 5
Dependent Claim 19 words
The composition of Claim 3 wherein the pyrophosphate source is a mixture of tetrasodium pyrophosphate and tetrapotassium pyrophosphate salts.
Claim 6
Dependent Claim 29 words
The composition of Claim 4 wherein said dental abrasive is selected from the group consisting of beta-phase calcium pyrophosphate, insoluble metaphosphates, alumina, thermosetting polymerized resins, silica, and mixtures thereof.
Claim 7
Dependent Claim 15 words
The composition of Claim 5 wherein said composition comprises at least about 0.5% sodium cyclamate.
