ABSTRACT:
A novel aqueous-based, neutral pH gel dentifrice composition containing fluoride and optionally containing hydrated silica is provided. The dentifrice composition contains about 15% to about 25% by weight of a polyoxyethylene polyoxypropylene block copolymer gelling agent, about 5% to 15% by weight of a humectant, about 0.1% to about 4.0% by weight of a surfactant, about 0.1% to about 2% of a fluoride source, and an effective amount of a flavor ingredient and an effective amount of a buffering agent whereby the pH of the final composition is essentially neutral. The dentifrice exhibits unique rheological properties making it particularly suitable for use with electromechanical tooth brushing devices of the type having independently moving tufts.
