Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
127 words
An anhydrous heat releasing fluoride dentifrice which generates heat in the mouth enhancing the fluoride anticaries action and which effects a two tone flavor change in the oral cavity consisting of a finely divided anhydrous synthetic zeolite having an appreciable heat of hydration and capable of being reversibly dehydrated as the sole or major dental polishing agent in amounts of about 10 to 50% by weight which synthetic zeolite is a crystalline metal alumino silicate, said metal being selected from the group consisting of an alkali metal, alkaline earth metal, zinc, copper and mixtures thereof, an effective amount of a fluorine containing compound, about 0.1 to 5% by weight of at least one flavoring agent, and about 20 to 75% by weight of an anhydrous liquid vehicle.
Claim 2
Dependent Claim
