Claims11
A toothpaste containing about 20 to 60% of abrasive particles containing at least about 25% sodium bicarbonate in a vehicle containing sufficient liquids and including a water-glycerol mix, the water-glycerol ratio being in the range of about 0.4 to 0.7:1, said vehicle consisting essentially of about 5 to 35% water and said glycerol and a sufficient amount of gelling or thickening agent to impart to the dental cream the pasty consistency, body and non-tacky nature which is characteristic of conventional dental creams or toothpastes, said toothpaste containing a water-insoluble essential oil flavoring agent in the range of about 0.5 to 1.5%, said sodium bicarbonate being primarily in the undissolved solid state, said dental cream having a granular textured appearance comprising a substantially dispersed noncrystalline appearing granulate of macroscopic crystalline bicarbonate granules in an otherwise smooth continuous matrix.
