Abstract

Method of making abrasive compositions comprised of water-insoluble abrasive polishing agents suspended in an aqueous medium in combination using wet grinding, and products thereof. The abrasive compositions made by the method contain appropriately sized abrasive particles provided without the need for drying or dry milling, while also providing an abrasive composition which is theologically 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.
