ABSTRACT:
The present invention relates to a dentifrice formulation comprising first and second dentifrice compositions and to a dentifrice formulation that is a single dentifrice composition. The first dentifrice composition or the single dentifrice composition will comprise from about 0.1% to about 10% of a surfactant selected from the group consisting of anionic surfactants, cationic surfactants, amphoteric surfactants, and mixtures thereof; from about 0.1% to about 10% of a charged polymer; and from about 80% to about 99% of one or more aqueous carriers; wherein the charged polymer is diluted to form a charged polymer slurry and the pH of the charged polymer slurry is from about 1.5 to about 10, the charged polymer slurry is combined with the anionic, cationic, or amphoteric surfactant to form a coacervate gel, and the coacervate gel is then combined with the one or more aqueous carriers to form the dentifrice composition. The present invention also relates to a method of making a dentifrice composition containing a coacervate gel, comprising the steps of diluting from about 0.1% to about 10% of a charged polymer to form a charged polymer slurry, the charged polymer slurry having a pH of from about 1.5 to about 10; combining the charged polymer slurry with from about 0.1% to about 10% of a surfactant selected from the group consisting of anionic surfactants, cationic surfactants, amphoteric surfactants, and mixtures thereof, to form a coacervate gel; and combining the coacervate gel with from about 80% to about 99% of one or more aqueous carriers to form the dentifrice composition.
