Abstract
A formulation which consists essentially of from about 20%, by weight, to about 87%, by weight, zinc oxide, from about 13% to about 80%, by weight of a selected type of acidic pH adjuster, and from about 0% to about 7%, by weight, of trimagnesium phosphate, when incorporated in fluorine-containing toothpaste formulations which also contain at least one compound selected from the group consisting of an insoluble alkali metal metaphosphate and calcium pyrophosphate, yields a smooth paste having a pH of from about 5.5 to about 6.8 which will not corrode the inside of unlined aluminum tubes containing such a formulation. When the components of the formulation are based on the weight of the entire toothpaste formulation, said zinc oxide can be present at from about 0.05% to about 2.0%, the acidic pH adjuster can be present at from about 0.05% to about 3.0%, and the trimagnesium phosphate can be present at from about 0% to about 0.5%.
