Abstract: Provided is an oral care composition, e.g., a dentifrice, comprising a calcium abrasive, e.g., calcium carbonate, potassium nitrate (KNO3), and a basic amino acid, in free or salt form, e.g., arginine, in free or salt form, wherein the potassium nitrate is present in an amount of 0.1-1% by weight of the composition and methods of using the same.

Abstract: A method of determining the viability of a gum for use in making a product has been achieved by (a) mixing a sample of the gum in a solvent comprising one or more hydroxy moiety containing solvent compound to form a solution with the gum; (b) measuring the viscosity of the solution and comparing against a predetermined target viscosity for a product; and (c) comparing the viscosity of the solution and the predetermined target viscosity and discarding gum which is outside the predetermined target viscosity; and (d) using the gum which has a viscosity within the predetermined target to prepare a product; wherein another hydroxy moiety containing solvent is used if water is used as a solvent. Also described are compositions comprising the gum and solvent comprising one or more hydroxy moiety.
