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) fromabout 0.1 % to about 30 % of one or more linear polyphosphates having anaverage chain length of about 4 or more; (b) an ionic active ingredientselected from the group consisting of a fluoride ion source, a stannous ionsource, a zinc ion source, a copper ion source and mixtures thereof, whereinthe ionic active ingredient is present as a solid dispersion in thecomposition 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 athickening 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 thedentifrice composition has a total water content of less than about 10 %.Further disclosed are methods for stabilizing dentifrice compositions byproviding such a binder system.
