Abstract:
Process for heat treating precipitated silica to improve stability. Oral care compositions comprising such heat treated precipitated silica abrasives and a stannous ion source.

Claim (Index 20):
An oral care composition comprising:\n (a) from about 5 wt % to about 50 wt % of heat treated precipitated silica particles by weight of the composition; (b) from about 1.5 wt % to about 3 wt % of stannous fluoride, by weight of the composition, wherein the said heat treated precipitated silica particles were heat treated by subjecting the precipitated silica particles to a temperature of about 800\u00b0 C. to about 1050\u00b0 C. for a time period of less than about 5 minutes; wherein the heat treated precipitated silica particles have a Q4 normalized integral value of Q2 greater than about 5489; and wherein the oral care composition is a dentifrice.
