Abstract
A storage stable aqueous oral composition which is effective against calculus which contains an orally acceptable vehicle having incorporated therein from about 10% to up to about 15% by weight water, an effective anticalculus combination of about 0.5 to about 2% by weight of a water soluble pyrophosphate salt and about 0.5 to about 3% by weight of a water soluble polyphosphate salt. The presence in the composition of relatively high amounts of water affect the stability of the composition.
