Problems solved by technology

[0003] Although any of the prior art allows the mixing of ethanol, however, in recent years, there is a problem of irritation caused by ethanol when a low-irritating feeling of use is required, and a composition without ethanol tends to be desired
[0004] However, when ethanol is not mixed, there are problems in that it is difficult to ensure the stability of the appearance of a composition mixed with a cationic fungicide and hydroxyethylcellulose dimethyl diallyl ammonium chloride, and it is difficult to ensure both non-irritating and Time-dependent stability of appearance
Furthermore, astringency, bitterness, and peculiar taste from the cationic fungicide and hydroxyethyl cellulose dimethyl diallyl ammonium chloride will also be produced, and the effects of the two components and the palatability of the preparation are difficult to coexist

Abstract

The present invention provides an ethanol-free liquid oral composition, which has an excellent plaque adhesion inhibitory effect and excellent bactericidal power against Streptococcus mutans in tartar, and has improved appearance stability and palatability. good. A liquid oral composition comprising (A) a cationic bactericide and (B) hydroxyethylcellulose dimethyl diallyl chloride in a substantially ethanol-free liquid oral composition At the same time as ammonium chloride, and use (C) anethole, wherein the mass ratio of (C) component / [(A) component + (B) component] is in the range of 0.1 to 10, and mixing (D) polyhydric alcohol and / or (E) nonionic surfactant. A method for stably mixing (A) and (B) components in the composition, characterized in that, while mixing (A) and (B) components in the liquid oral composition, (C) Components, wherein (C) / [(A)+(B)] is in the range of 0.1 to 10, and (D) and / or (E) components are mixed.

Description

technical field [0001] The present invention relates to an ethanol-free liquid composition for oral cavity and a method for stabilizing and mixing components in the composition, which exhibits an excellent effect of inhibiting the adhesion of tartar on the tooth surface and is excellent against Streptococcus mutans in tartar In addition to the bactericidal power, the appearance stability (no sediment) is improved, and the palatability is also good. Background technique [0002] Suppression of dental plaque is important in the prevention of periodontal disease and dental caries, and compositions for oral cavity containing a bactericide for the purpose of suppressing dental plaque are widely used. Cationic bactericides among these bactericides are widely used because they have oral bacteria sterilizing effects, plaque suppressing effects, and gingivitis-improving effects. In addition, Patent Document 1 (Japanese Unexamined Patent Publication No. 2001-64137) proposes a liquid ...
