Toothpaste containing pH-adjusted zeolite

Claim 1

A dentifrice formulation having a pH range outside the 4.2 to 5.4 demineralization threshold and which is acceptable psychosensorily to persons who will use it; said dentifrice being a toothpaste containing 5-80% by weight pH-modified zeolite and being free from zeolites that are not pH-modified; said pH-modified zeolite being the result of slurrying a zeolite and slowly adding acid solution until the pH of the solution is 5.5-6.0, and therefore personally acceptable, said non-pH-modified zeolites not having personal acceptance; said pH-modified zeolite having a slurry pH of 5.5-6.0 without the significant reduction of the crystal structure that would be caused by more severe treatment at pH 4 or less; said pH-modified zeolite having a particle size of 0.5 to 3.5 μm and about an order of magnitude smaller than commercially acceptable abrasive agents that exhibit the same or less abrasion; said acid slurried pH-modified zeolite not being crushed or fragmented or use but still providing polishing and lustering and providing good pasting properties to said toothpaste, said toothpaste being free from other abrasives and lustering agents; said acid slurried pH-modified zeolite imparting a pH of 6 or above but below the pH at which there is personal objection to the taste and sense of dehydration to the mouth.
