Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
120 words
An oral composition in the form of a toothpaste characterized in that it comprises: a) from 10% to 70% by weight of a dental abrasive selected from insoluble metaphosphates, alumina, thermosetting polymerized resins, silica and mixtures thereof; b) an amount of a fluoride ion source sufficient to supply from 50 ppm to 3500 ppm of fluoride ions; c) an amount of a pyrophosphate salt selected from dialkali metal and mixtures of dialkali metal and tetraalkali metal pyrophosphate salts sufficient to provide at least 1.5% by weight of pyrophosphate ions (P₂O₇⁻⁴); and d) water; wherein the pH of the composition is from 6.0 to 10.0 and wherein are excluded compositions containing no more than 4.0% by weight of tetrapotassium pyrophosphate (K₄P₂O₇).
Claim 2
Dependent Claim
120 words
An oral composition in the form of a toothpaste characterized in that it comprises: a) from 10% to 70% by weight of a dental abrasive selected from insoluble metaphosphates, alumina, thermosetting polymerized resins, silica and mixtures thereof; b) an amount of a fluoride ion source sufficient to supply from 50 ppm to 3500 ppm of fluoride ions; c) an amount of a pyrophosphate salt selected from dialkali metal and mixtures of dialkali metal and tetraalkali metal pyrophosphate salts sufficient to provide at least 1.5% by weight of pyrophosphate ions (P₂O₇⁻⁴); and d) water; wherein the pH of the composition is from 6.0 to 10.0 and wherein are excluded compositions containing no more than 4.0% by weight of tetrapotassium pyrophosphate (K₄P₂O₇).
