Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
86 words
A dental cream composition free of calcium carbonate comprising a polishing material which consists essentially of a water-insoluble phosphate salt, at least a major portion of which is an insoluble sodium metaphosphate in a dentifrice vehicle containing an alkali metal monofluorophosphate and an alkali metal fluoride in amount to provide a total fluoride content of about 0.01-1.5% by weight to the dentifrice, the weight ratio of fluoride from the alkali metal monofluorophosphate to the fluoride from the alkali metal fluoride being about 10:1 to about 1:10.
Claim 2
Dependent Claim
86 words
A dental cream composition free of calcium carbonate comprising a polishing material which consists essentially of a water-insoluble phosphate salt, at least a major portion of which is an insoluble sodium metaphosphate in a dentifrice vehicle containing an alkali metal monofluorophosphate and an alkali metal fluoride in amount to provide a total fluoride content of about 0.01-1.5% by weight to the dentifrice, the weight ratio of fluoride from the alkali metal monofluorophosphate to the fluoride from the alkali metal fluoride being about 10:1 to about 1:10.
Claim 3
Dependent Claim
33 words
The dental cream composition claimed in claim 1 wherein said weight ratio of fluoride from the alkali metal monofluorophosphate to the fluoride from the alkali metal fluoride is about 3:1 to about 1:1.
Claim 4
Dependent Claim
21 words
The dental cream composition claimed in claim 2 wherein said polishing material is present in amount of about 20-75% by weight.
Claim 5
Dependent Claim
29 words
The dental cream composition claimed in claim 2 wherein said polishing material consists essentially of a major amount of insoluble sodium metaphosphate and a minor amount of dicalcium phosphate.
Claim 6
Dependent Claim
25 words
The dental cream composition claimed in claim 4 wherein said dicalcium phosphate is present in amount of about 5-20% by weight of the polishing material.
Claim 7
Dependent Claim
24 words
The dental cream composition claimed in claim 2 wherein said alkali metal monofluorophosphate is sodium monofluorophosphate and said alkali metal fluoride is sodium fluoride.
Claim 8
Dependent Claim
34 words
The dental cream composition claimed in claim 6 wherein said sodium monofluorophosphate is present in amount of about 0.38-1.14% by weight and said sodium fluoride is present in amount of about 0.06-0.11% by weight.
