ABSTRACT A process for making a toothpaste comprising an aqueous liquid humectant phase consisting essentially of an aqueous sorbitol solution thickened by a hydrated binder comprising a hydrated plant gum, and a water-insoluble particulate abrasive agent dispersed in the thickened liquid phase. Hydration of the plant gum is carried out by mixing under shear the plant gum with a liquid hydration medium consisting of water and 0 to 33% by weight of the liquid hydration medium of sorbitol. The mixing is carried out in the presence of such an amount of the particulate abrasive agent that sufficient shear is produced during the mixing to effect uniform hyration of the plant gum with the production of a smooth cream, whereafter there is blended with the hydrated plant gum any remaining water and humectant, any remaining abrasive, and other conventional ingredients, to produce the toothpaste.
