  • Dentifrice compositions having reduced abrasivity
    Patent number: 6861048
    Abstract: A method for reducing an abrasivity of a dentifrice composition containing an abrasive, includes incorporating into the dentifrice composition a zinc salt in an amount sufficient to reduce a dentinal abrasivity of the composition by at least 10% and reduce an enamel abrasivity of the dentifrice composition by at least 10%. The method provides an improved dentifrice composition, which is at least 90% as effective at stain removal as the original dentifrice composition. Suitable zinc salts include, e.g., zinc citrate, zinc chloride, zinc acetate, zinc oxide and zinc sulfate. Suitable abrasives include, e.g., silica, alumina and alkali metal meta-phosphates.
    Type: Grant
