Abstract
Dentifrice composition containing a monofluorophosphate and polishing agent containing calcium carbonate and insoluble alkali metal metaphosphate, alumina or mixture therof. The ratio of calcium carbonate to insoluble alkali metal metaphosphate and to alumina is about 3:1 to about 1000:1. This dentifrice retains a desirable level of soluble fluoride upon aging and when insoluble alkali metal metaphosphate is present, does not cause substantial corrosion of unlined aluminum containers.
Claims6
A dental cream composition comprising a water-soluble monofluorophosphate in amount which provides about 0.01-1% by weight fluorine to the dentifrice and about 20-75% by weight of a water-insoluble compatible polishing material consisting essentially of a mixture of calcium carbonate with insoluble alkali metal metaphosphate, the ratio of said calcium carbonate to said insoluble alkali metal metaphosphate being about 3:1 to about 1000:1;--said dentifrice having an initial pH of about 7 to 9.5.
