ABSTRACT:
The present invention relates to a stannous fluoride-containing gel comprising from about 0.3% to about 1.0% (by weight) stannous fluoride, from about 1.0% to about 10% (by weight) silica thickening agent and anhydrous glycerin. Preferably, these gels also contain from about 0.01% to about 5% (by weight) of a gum system, e.g. hydroxyethyl cellulose. These gels exhibit very good ribbon stand-up qualities and excellent fluoride ion and stannous ion stability. Also, the present invention relates to an improved method for producing the above gels. This method uses mixing equipment commonly employed to manufacture dentifrices and provides a simplified processing scheme.
