Patent ID: 8591867

Claim:
A multi-composition oral preparation system comprising the following components: a first composition comprising: (A) a calcium ion supplying compound in an amount allowing a concentration of the calcium ion in the first composition to be from 1.25 to 400 μmol/g, (C) a polyolphosphate ion supplying compound in an amount allowing a concentration of the polyolphosphate ion in the first composition to be from 1.25 to 400 μmol/g, and (D) a monofluorophosphate ion supplying compound in an amount allowing a concentration of the monofluorophosphate ion in the first composition to be from 2.6 to 210 μmol/g, and a second composition comprising: (B) a fluoride ion supplying compound, other than a monofluorophosphate ion supplying compound, in an amount allowing a concentration of the fluoride ion in the second composition to be from 2.6 to 210 μmol/g, wherein the components (A) and (B) are separated within the oral preparation system, and the second composition does not comprise a phosphate ion supplying compound, and wherein said polysphosphate ion supplying compound is at least one of calcium polyolphosphates selected from the group consisting of calcium glycerophosphate, calcium glucose-1-phosphate and calcium glucose-6-phosphate.
