ABSTRACT:
A stable antiplaque dentifrice with improved foaming and improved fluoride stability containing an antiplaque quaternary ammonium compound, a betaine surfactant to improve foaming without inactivating the anti-bacterial and antiplaque activity of the quaternary ammonium compound, a humectant selected from the group consisting of polyethylene glycol, sorbitol, and mixtures thereof, a nonionic gelling agent, preferably hydroxyethylcellulose and a fluorine-containing compound capable of providing a fluoride ion, a small amount of glycerin to improve fluoride stability in polyethylene glycol humectant, in an aqueous vehicle containing a dental abrasive. A small amount of glycerin, as low as 1%, improves the long term fluoride stability of the dentifrice without adversely affecting the cosmetic stability thereof.
