This invention relates to high-water oral care compositions comprising a basic amino acid or salt thereof, together with a precipitated calcium carbonate, glycerol, and to methods of using and of making these compositions.

Oral care product and methods of use and manufacture thereof

The present invention provides calcium carbonate-based oral care compositions, in particular toothpastes comprising a thickening system comprising 0.2-0.5 wt. % xanthan gum and 0.2-0.5 wt. % synthetic polyacrylic acid polymer, as well as methods of using these compositions.

Toothpastes containing calcium carbonate, xanthan gum and polyacrylic acid polymer

The present disclosure is directed to a method for reducing bacteria in a precipitated calcium carbonate (CaCO) slurry, the method including: adding water to calcium oxide (CaO) to form Ca(OH); treating the Ca(OH)with COgas to form a slurry including precipitated CaCO; neutralizing the slurry; and exposing the slurry that was neutralized to ozone in an amount sufficient to reduce bacteria in the precipitated calcium carbonate slurry. Oral care compositions including the precipitated calcium carbonate of the disclosed process are also described.

Use of ozone to control bioburden in precipitated calcium carbonate slurry (PCC)

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.
