Abstract
Abstract Dental cream suitable for use in an unlined aluminum container comprising between about 35 and 60% of abrasive containing alumina as the major abrasive component and as agents to render the dental cream compatible with an unlined aluminum container, calcium carbonate present as minor abrasive component in amount of at least about 1% of the dental cream and a dissolved or dispersed silicate present in amount of about 0.05-0.25%. The composition also desirably contains a water-soluble monofluorophosphate salt in amount which provides 0.01-1% fluoride in the dental cream and when the dental cream contains the monofluorophosphate salt and more than about 5% calcium carbonate, an alkali metal tripolyphosphate in an amount up to about 1.5% is also present.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
123 words
A dental cream suitable for compatible incorporation into an unlined aluminum container comprising a dental cream vehicle having dispersed or dissolved therein a water-soluble monofluorophosphate salt selected from the group consisting of alkali metal, calcium, magnesium and aluminum monofluorophosphates in an amount which provides between about 0.01 and 1% fluoride to said dental cream, about 35 to 60% by weight of abrasive which abrasive consists essentially of alumina in excess of calcium carbonate, said calcium carbonate being in amount of at least about 5% by weight of the total dental cream, an alkali metal tripolyphosphate in an amount of about 0.05 up to about 1.5% by weight and between about 0.05 and about 0.25 % by weight of a dissolved or dispersed silicate.
Claim 2
Dependent Claim
123 words
A dental cream suitable for compatible incorporation into an unlined aluminum container comprising a dental cream vehicle having dispersed or dissolved therein a water-soluble monofluorophosphate salt selected from the group consisting of alkali metal, calcium, magnesium and aluminum monofluorophosphates in an amount which provides between about 0.01 and 1% fluoride to said dental cream, about 35 to 60% by weight of abrasive which abrasive consists essentially of alumina in excess of calcium carbonate, said calcium carbonate being in amount of at least about 5% by weight of the total dental cream, an alkali metal tripolyphosphate in an amount of about 0.05 up to about 1.5% by weight and between about 0.05 and about 0.25 % by weight of a dissolved or dispersed silicate.
Claim 3
Dependent Claim
17 words
The dental cream of claim 1 containing between about 0.15% and 1% by weight of said tripolyphosphate.
Claim 4
Dependent Claim
37 words
The dental cream of claim 2 wherein said water-soluble monofluorophosphate is sodium monofluorophosphate, said silicate is sodium silicate and said tripolyphosphate is sodium tripolyphosphate and is present in an amount between about 0.2 and 0.7% by weight.
Claim 5
Dependent Claim
120 words
A packaged dental cream comprising an unlined aluminum tube and contained therein a dental cream vehicle having dispersed or dissolved therein a water-soluble monofluorophosphate salt selected from the group consisting of alkali metal, calcium, magnesium and aluminum monofluorophosphates in an amount which provides between about 0.01 and 1% fluoride to said dental cream, about 35 to 60% by weight of abrasive which abrasive consists essentially of alumina in excess of calcium carbonate, said calcium carbonate being in amount of at least 5% by weight of the total dental cream, an alkali metal tripolyphosphate in an amount of about 0.05 up to about 1.5% by weight and between about 0.05 and about 0.25% by weight of a dissolved or dispersed silicate.
Claim 6
Dependent Claim
120 words
A packaged dental cream comprising an unlined aluminum tube and contained therein a dental cream vehicle having dispersed or dissolved therein a water-soluble monofluorophosphate salt selected from the group consisting of alkali metal, calcium, magnesium and aluminum monofluorophosphates in an amount which provides between about 0.01 and 1% fluoride to said dental cream, about 35 to 60% by weight of abrasive which abrasive consists essentially of alumina in excess of calcium carbonate, said calcium carbonate being in amount of at least 5% by weight of the total dental cream, an alkali metal tripolyphosphate in an amount of about 0.05 up to about 1.5% by weight and between about 0.05 and about 0.25% by weight of a dissolved or dispersed silicate.
