  • Toothpaste formulations
    Patent number: 4089943
    Abstract: Toothpaste formulations having dispersed therein a plurality of agglomerated particles of dental polishing agent that are visible, palpable and substantially insoluble in the toothpaste are disclosed. The agglomerates comprise individually impalpable particles of water insoluble dental polishing agent; can include an agglomerating agent and are reduced to smaller sized particles of dental polishing agent when subjected to mild mechanical agitation such as toothbrushing. Such agglomerates are particularly well suited for incorporation into transparent gel dental vehicles to provide special effects such as supplemental cleaning and polishing characteristics without adversely affecting the visual clarity of the finished toothpaste.

  • Dentifrice containing visible agglomerated particles of polishing agents
    Patent number: RE29634
    Abstract: Dentifrice containing visible, palpable and esthetically pleasing substantially water-insoluble agglomerated particles of polishing agents. The particles are reduced to smaller impalapable size by mild mechanical action such as by toothbrushing. The agglomerates include water-insoluble polishing agent such as insoluble sodium metaphosphate or dicalcium phosphate and may also contain a binding agent such as gum acacia, gelatin, starch, carboxymethyl cellulose or the like.
