Dentifrice comprising carboxylic acid or alkali metal salt thereof and a source of free fluoride ions

Abstract

A dentifrice composition is described comprising a copolymer of MVE with maleic acid; lactic acid or alkali metal salt thereof; and a source of fluoride ions, wherein the copolymer is present in an amount of range 0.9% to 1.1% by weight of the total composition; wherein the lactic acid or alkali metal salt thereof is present in an amount of 1% to 4% by weight of the total composition, wherein the dentifrice composition is mildly acidic, having a slurry pH in the range 5.0 to 6.5. The composition enhances fluoride uptake into teeth and provides protection against acidic challenges.
