An oral dentifrice composition such as a toothpaste, dental gel, toothpowder, dental tablet or lozenge containing as anticalculus agent about 4.3% to about 7% of alkali metal pyrophosphates comprising at least 4.3% of tetrapotassium pyrophosphate alone or admixed with up to 2.7% of tetrasodium pyrophosphate, and as inhibitors against enzymatic hydrolysis of such agent in saliva, a fluoride and preferably up to about 3% of a synthetic anionic polymeric polycarboxylate, and use of such composition in a program of oral hygiene and/or for inhibiting dental calculus.

Anticalculus oral composition

A chemically and physically stable antiplaque dentifrice comprising an antiplaque quaternary ammonium compound, a betaine surfactant, a humectant system of glycerin and/or sorbitol and a nonionic gelling agent, prepared by a process which comprises the preparation of two separate gel phases, an oil gel phase and a water gel phase, combining said gel phases into a single gel, and adding a dental abrasive thereto as the final step, or adding said abrasive to the water gel phase prior to the addition of the oil gel phase.
