Abstract
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.
Claims9
An oral composition containing an orally acceptable aqueous vehicle and, in approximate weight amounts and proportions,
- A. at least 4.3% of a mixture of alkali metal pyrophosphates containing tetrasodium pyrophosphate and tetrapotassium pyrophosphate in a respective ratio ranging from 2.7:4.3 to 1:6 and sufficient tetrapotassium pyrophosphate to avoid the occurrence of gritty particles of tetrasodium pyrophosphate in the composition, and
- B. an amount of a fluoride ion source sufficient to supply 25 ppm to 5,000 ppm of fluoride ions.
An oral composition containing an orally acceptable aqueous vehicle and, in approximate weight amounts and proportions,
- A. 4.3% to 7% of a mixture of tetrasodium pyrophosphate and tetrapotassium pyrophosphate in a respective ratio ranging from 2.7:4.3 to 1:6;
- and
- B. an amount of a fluoride ion source sufficient to supply 25 ppm to 5,000 ppm of fluoride ions.
An oral composition containing an orally acceptable aqueous vehicle and, in approximate weight amounts and proportions;
- A. 0-90% of a dentally acceptable polishing agent,
- B. an amount of fluoride ion source sufficient to supply 223 ppm to 9,050 ppm of fluoride ions;
- and
- C. an amount of at least one pyrophosphate source sufficient to provide at least 2.3% of pyrophosphate ion;
- wherein the pH of said composition is about 4.5 to about 10;
- and said composition contains sodium ions and potassium ions in a respective ratio of 0.1:1 to 1.04:1.
