DENTIFRICE CONTAINING NEUTRAL SILICEOUS ABRASIVE

摘要

There is disclosed a dentifrice formulation which is stable in the sense of not producing gassing as evidenced by visually discernable distention over a period of 168 days at 43 DEG C. in an unlined aluminium tube. The formulation comprises an aqueous dentally acceptable oral vehicle at least 27.5% by weight of the dentifrice comprising water and dispersed in the said oral vehicle from 10 to 40% by weight of the dentifrice of a neutral siliceous polishing agent having a stirred slurry pH (as herein defined) in the range from 6.5 to 7.5, and a stabilizing amount of monofluorophosphate ion, the dentifrice having a stirred slurry pH in the range from 5.5 to 8.
