Abstract
The invention concerns a process for making a toothpaste containing an abrasive agent and a binder consisting wholly or partly of guar gum or other plant gum. The plant gum is hydrated by a liquid hydration medium consisting of water and 0 to 33% by weight of the hydration medium of sorbitol. To hydrate the plant gum it is mixed with the hydration medium in the presence of sufficient of the abrasive agent to produce enough shear to give a smooth cream. Other conventional ingredients are then mixed in.

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, which is guar gum, and a water-insoluble particulate abrasive agent dispersed in the thickened liquid phase, said process comprising the steps of:
- a) hydrating the plant gum by mixing the gum under shear with a liquid hydration medium consisting of water and from 1 to less than 25% by weight of the liquid hydration medium of sorbitol, the mixing being conducted in the presence of an amount of particulate abrasive agent in an effective amount to produce sufficient shear during the mixing to effect uniform hydration of the plant gum with production of a smooth cream;
- and
- b) blending the hydrated plant gum resulting from step (a) with a further amount of sorbitol, any remaining water, any remaining abrasive and other conventional ingredients, to produce the toothpaste.
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, which is guar gum, and also hydrated xanthan gum, and a water-insoluble particulate abrasive agent dispersed in the thickened liquid phase, said process comprising the steps of:
- a) hydrating the plant gum by mixing the gum under shear with a liquid hydration medium consisting of water and from 1 to less than 25% by weight of the liquid hydration medium of sorbitol, the mixing being conducted in the presence of an amount of particulate abrasive agent in an effective amount to produce sufficient shear during the mixing to effect uniform hydration of the plant gum with production of a smooth cream;
- and
- b) blending the hydrated plant gum resulting from step (a) with a further amount of sorbitol, and any remaining water, any remaining abrasive and other conventional ingredients, to produce the toothpaste.
