Problems solved by technology

[0006] However, the dentifrice composition that has been formulated with ascorbyl phosphate or its salt, especially if it is formulated with calcium carbonate-based abrasives, has the problem that the stability of ascorbyl phosphate or its salt is significantly reduced, so there is almost no calcium carbonate. Abrasive is added as the main abrasive

Abstract

Provided is a dentrifice composition that stably contains an ascorbic acid phosphate ester or a salt thereof and provides a good sensation of cleaning. A dentrifice composition characterized by containing (B) a calcium-carbonate abrasive and (C) at least one compound selected from among hydrogen carbonate, orthophosphate, and condensed phosphate in (A) a dentrifice composition containing an ascorbic acid phosphate ester or a salt thereof. This dentrifice composition is further characterized in that the quotient of the mass of component (C) and the mass of component (B) is between 0.020 and 1.0, inclusive.

Description

technical field [0001] The present invention relates to a dentifrice composition capable of stably blending ascorbyl phosphate or a salt thereof and having a good feeling upon use. Background technique [0002] In recent years, ascorbyl phosphate or a salt thereof has attracted attention as an antioxidant vitamin capable of eliminating excess active oxygen generated in a living body and protecting biological tissues from oxygen damage. Ascorbyl phosphate or its salt has various physiological activities, and it is known in the field of oral cavity that it is effective in the prevention / treatment of gingivitis and periodontitis (Patent Document 1), and it is tried to be mixed with oral compositions such as toothpaste or tablets middle. [0003] However, when ascorbyl phosphate or its salt is blended into various compositions, the residual rate of ascorbyl phosphate or its salt will decrease due to the influence of metals such as calcium, microorganisms, and pH, etc., and its ...
