Abstract

A dentifrice composition which comprises (A) heavy calcium carbonate having a mean particle diameter of 5 to 15 m, (B) water-insoluble inorganic granules having a collapse strength of 10 to 200g / granule, a mean particle diameter of 50 to 150 m, and a difference of 100 m or below between 90% particle diameter and mean particle diameter, and (C) a water-soluble polymeric material comprising at least one member selected from Group (a) and at least one member selected from Group (b) at a (b) / (a) mass ratio of 0.25 to 3, Group (a): sodium alginate, sodium carboxymethylcellulose, methylcellulose, hydroxyethylcellulose, Xanthomonas campestris, lambda-carrageenan, and straight-chain sodium polyacrylate, and Group (b): gellan gum, agar, kappa-carrageenan, iota-carrageenan, gelatin, pectin, and crosslinked sodium polyacrylate, and which has a total content of (a) and (b) of 0.5 to 1.5% by mass based on the whole of the composition.

Description

toothpaste composition technical field The present invention relates to a toothpaste composition having an appropriate grinding force and a good feeling of use due to the synergistic effect of the real brushing feeling of the particles and the excellent toothpaste dispersibility. Background technique The abrasiveness of a toothpaste composition is considered to be related to the hardness, particle size and compounding amount of the abrasive used. That is, for relatively soft abrasives such as calcium hydrogen phosphate (around 2 to 3 on the Mohs scale), a large amount of abrasives with large particle diameters can be compounded in the toothpaste composition. However, relatively hard abrasives such as silicic anhydride (around 4 to 6 on the Mohs scale) can only be reduced in particle size and compounded in a small amount in the toothpaste composition. On the other hand, the hardness, particle diameter, and compounding amount of abrasives also have a great influence on the...
