Abstract
Toothpaste formulations having dispersed therein an invisible abrasive material and visible abrasive agglomerates are disclosed. The abrasive agglomerates comprise subparticles of hard abrasive materials (Moh hardness of at least about 5) joined together by a binding agent material, and provide increased cleaning and polishing characteristics as well as an attractive speckled appearance to the toothpaste formulation.
