DENTIFRICE COMPRISING A PVM-MA COPOLYMER AND A SOURCE OF FREE FLUORIDE IONS

摘要

A dentifrice composition is described comprising a source of free fluoride ions; and from 0.1% to less than 0.5% by weight of the composition of a copolymer of methyl vinyl ether with maleic anhydride or acid; and wherein the composition has a slurry pH from 6.0 to 7.5, and wherein the composition is free of a carboxylic acid or alkali metal salt thereof wherein the acid is selected from the group consisting of malonic acid, glutaric acid, tartaric acid, lactic acid and mixtures thereof. The composition enhances fluoride uptake into teeth and provides protection against acidic challenges.
