Toothpaste

A dental cream in an unlined aluminum tube, said dental cream containing an abrasive content comprising at least about 20% sodium bicarbonate in a vehicle containing sufficient liquids, said vehicle consisting essentially of about 5 to 35% water and sufficient viscous water miscible polyol humectant or mixtures thereof, and a sufficient amount of gelling or thickening agent to impart to the dental cream the pasty consistency, body and the non-tacky nature which is characteristic of conventional dental creams or toothpastes, and over 1% anhydrous dicalcium phosphate, said sodium bicarbonate being primarily in the undissolved solid state, said dental cream having a granular textured appearance comprising a substantially dispersed non-crystalline appearing granulate of macroscopic crystalline bicarbonate granules in an otherwise smooth continuous matrix.
