  • Dentifrice composition
    Patent number: 3956478
    Abstract: Dentifrice composition containing a monofluorophosphate and polishing agent containing calcium carbonate and insoluble alkali metal metaphosphate, alumina or mixture thereof. 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.
