Abstract
Crystalline alumino-silicates (zeolites) are multifunctional in dentifrice compositions thereby reducing the number of components required in such formulations. The pH-adjusted zeolites can keep the pH of the dentifrice in the range where caries formation is impossible. The pH-adjusted synthetic or natural zeolites can be prepared or obtained in a particle size range that provides both abrasive cleansing and polishing or lustering of the teeth. The fine particle size and water absorbing capabilities of the zeolite can also provide thickening. Such multifunctional performance allows considerable simplification in the formulation of dentrifice compositions.
