  • Patent number: 6419174
    Abstract: Abrasive compositions comprised of water-insoluble abrasive polishing agents suspended in a liquid medium in combination with humectant, and methods for making same. The inventive abrasive compositions are rheologically stable, settling-resistant, and re-agglomeration resistant, even during and after transport and/or storage before end-use, such as incorporation into dentifrice formulations or other oral cleaning compositions. The high settling-resistance of the inventive abrasive composition makes it possible to avoid the need before end use for temporary stabilizers such as inorganic suspending agents (e.g., clays, fumed silicas) or organic binders (e.g., polysaccharides). Also, the abrasive compositions contain abrasive particles having improved brightness as compared to abrasive particles made via drying and dry comminution processing.
