DENTIFRICE COMPOSITIONS COMPRISING A STABLE LOW WATER PHASE COMPRISING POLYPHOSPHATE, IONIC ACTIVE INGREDIENTS AND BINDER SYSTEM

摘要

Disclosed are dentifrice compositions comprising in a single phase: (a) from about 0.1 % to about 30 % of one or more linear polyphosphates having an average chain length of about 4 or more; (b) an ionic active ingredient selected from the group consisting of a fluoride ion source, a stannous ion source, a zinc ion source, a copper ion source and mixtures thereof, wherein the ionic active ingredient is present as a solid dispersion in the composition and delivers an effective amount of ionic active when solubilized; (c) a binder system comprised of (i) from about 0.05 % to about 3 % of a thickening agent selected from the group consisting of polysaccharides, carbomers, poloxamers, modified celluloses, and mixtures thereof; and (ii) from about 0.1 % to about 70 % of at least one humectant; wherein the dentifrice composition has a total water content of less than about 10 %. Further disclosed are methods for stabilizing dentifrice compositions by providing such a binder system.
