Granular composition and dentifrice containing the same
First Claim
1. A granular composition, which comprises a water-soluble powder material selected from the group consisting of dibasic calcium phosphate, tribasic calcium phosphate, insoluble sodium metaphosphate, silica, aluminum hydroxide, magnesium phosphate, calcium carbonate, calcium pyrophosphate, zeolite, complex aluminosilicate, magnesium carbonate, red iron oxide, calcium sulfate and a mixture of two or more of them and a binder selected from the group consisting of colloidal silica, magnesium aluminate metasilicate, bentonite, montmorillonite, synthesized aluminum silicate, calcium silicate, aluminum hydroxide gel, alumina sol, magnesium carbonate, synthetic hydrotalcite, magnesium oxide, magnesium hydroxide and a mixture of two or more of the same;
- said composition containing granules having a diameter such that 80 wt. % or more of the granules are capable of passing through a No. 32 mesh of an analytical sieve, but are incapable of passing through No. 200 mesh of the sieve, and which collapse under a load of 0.1-10 g. per grain of granule.

Abstract
A novel granular composition comprises a water-insoluble powder material and a water-insoluble inorganic binder capable of binding said water-soluble powder material. Granules in the composition have a specific diameter and collapse under a load of 0.1-10 g per one grain of granule. The granular composition is preferably incorporated into a dentifrice, and granules incorporated therein can be recognized as granules in the mouth, however, polishing effect of the teeth can be acknowledged with almost no unpleasant feel of foreign substance.
