ORAL COMPOSITION FOR INHIBITING CALCULUS COMPRISING POLYPHOSPHATE SALTS, FLUORIDE IONS AND SYNTHETIC ANIONIC POLYMERIC POLYCARBOXYLATE SALTS

摘要

An oral composition containing in an orally acceptable vehicle, approximately by weight, an effective anticalculus amount in the range of 0.1 to 7% of one or a mixture of water soluble linear molecularly dehydrated alkali metal or ammonium polyphosphate salts as essential anticalculus agent, an amount of a fluoride ion source sufficient to supply 25 ppm to 2,000 ppm of fluoride ions, and one or a mixture of water soluble alkali metal or ammonium synthetic anionic polymeric polycarboxylate salts having a molecular weight of about 1,000 to 1,000,000, the polyphosphate ion:polycarboxylate salt weight ratio ranging from about 0.3:1 to about 2.5:1.
