Abstract

PROBLEM TO BE SOLVED: To improve the bitter taste and throat stimulation problems of dentifrice containing common salt and a fluorine compound. SOLUTION: The objective dentifrice contains (A) 1-30 wt.% of common salt, (B) 50-5,000 ppm of a fluorine compound in terms of fluorine and (C) 0.005-30,000 ppm of one or more compounds selected from anethole and menthyl acetate in total.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dentifrice, and more particularly, to a dentifrice containing a fluorine compound and salt and having good taste and no irritation to the throat.

[0002]

2. Description of the Prior Art Toothpastes contain fluorine compounds for the purpose of preventing dental caries. On the other hand, salt is included in dentifrices for the purpose of tightening gums. A dentifrice containing a salt and a fluorine compound has also been proposed (JP-A-1-268625).

[0003]

However, when salt and a fluorine compound are added to the dentifrice, the bitterness of the fluorine compound and irritation to the throat are further emphasized by the salt, and the palatability deteriorates.

[0004]

The inventor of the present invention has found that the addition of at least one selected from anethole and menthyl acetate in addition to sodium chloride and a fluorine compound significantly reduces the bitterness of the fluorine compound and irritation to the throat. I found that.

That is, the present invention provides (A) salt, (B)
An object of the present invention is to provide a dentifrice containing a fluorine compound and (C) at least one selected from anethole and menthyl acetate.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION As the salt (A) used in the present invention, granular salt is preferable, salt having a particle size of 100 μm or more is preferable, and salt having a particle size of 500 to 1500 μm is more preferable. The amount of the salt added to the dentifrice of the present invention is 1 to 30% by weight from the viewpoint of the effect on gums and the palatability of flavor.
(Hereinafter simply indicated by%), particularly preferably 5 to 20%.

As the fluorine compound (B), sodium fluoride, sodium monofluorophosphate, stannous fluoride, amine fluoride and the like can be mentioned, and sodium fluoride and sodium monofluorophosphate are preferable. (B)
The compounding amount of the fluorine compound is 50 to 5000 ppm in terms of fluorine, particularly 100 to 2000 ppm in terms of the effect of suppressing caries.
Is preferred.

[0008] (C) Anethole and menthyl acetate are components used as fragrances,
It is not known at all that reducing the bitterness of the fluorine compound and the irritation of the throat by adding it to the combined system of (A) salt and (B) the fluorine compound. Anethole and menthyl acetate may be used alone, but are more preferably used in combination. The amount of anethole and menthyl acetate added to the dentifrice of the present invention is 0.005 to 30,000 ppm in total in view of the taste improving effect, and particularly 0.05 to 1200 ppm.
0 ppm is preferred. In the case of anethole, 5-200
The content is preferably 00 ppm, particularly 50 to 10,000 ppm, and in the case of menthyl acetate, 0.005 to 10,000 ppm, particularly preferably 0.05 to 2000 ppm.

In the dentifrice of the present invention, flavors other than the above-mentioned component (C) can be used, and the amount of the flavor including the component (C) is 0.5 to 2%, particularly 0.7 to 1. 2% is preferred. Further, the content of anethole and menthyl acetate in the fragrance is 0.0001 to 100% in total, particularly 0.01 to 100%.
50% is preferred. In the case of anethole, 0.1 to 1
00%, especially 1 to 50%, preferably 0.0001 to 50%, especially 0.01 to 10% in the case of menthyl acetate
Is preferred.

Further, the dentifrice of the present invention includes abrasives such as calcium phosphate, calcium carbonate, aluminum hydroxide, silica, calcium pyrophosphate; glycerin;
Wetting agents such as sorbitol and propylene glycol; Binders such as carboxymethylcellulose, carrageenan and hydroxyethylcellulose; Surfactants such as sodium lauryl sulfate, N-acylglutamate, sucrose fatty acid ester; sweeteners such as saccharin sodium, stevioside, xylitol Agents: Pharmaceutical agents such as vitamin E, azulene allant inchlorohydroxyaluminum, dextranase, hinokitiol, lysozyme chloride, and chlorhexidine can be blended.

Although the method for producing the dentifrice of the present invention is not particularly limited, in the case of a toothpaste, the desired paste can be obtained by mixing and stirring the components and then degassing.

The form of the dentifrice of the present invention may be any of powder, paste, and solution.

[0013]

EXAMPLES Toothpastes having the compositions shown in Table 1 were prepared. Using this dentifrice, toothpaste was performed according to a conventional method, and bitterness and irritation of the throat were evaluated. Table 1 shows the results.

[Evaluation] ×: Strong bitterness / throat irritation. Δ: Slight bitterness / throat irritation. ：: No bitterness / throat irritation.

[0015]

[Table 1]

From the results shown in Table 1, it can be seen that when salt and fluorine compound are used together, the bitterness of the fluorine compound and irritation to the throat are increased.

Next, dentifrices were prepared by adding fragrances containing anethole and / or menthyl acetate to dentifrices 4 to 9 in Table 1 as shown in Table 2. These were brushed in accordance with a conventional method, and the effects of improving bitterness and throat irritation were evaluated. Table 2 shows the results. In addition, the result is dentifrice 4 ~
All of 9 were the same.

[Evaluation Criteria] ×: Bitterness / throat irritation is not improved. Δ: Bitterness / throat irritation is slightly improved. ：: Bitterness / throat irritation is improved. A: Bitterness and throat irritation are significantly improved.

[0019]

[Table 2]

As described above, it can be seen that the addition of anethole or menthyl acetate significantly improves the bitterness of the dentifrice and irritation of the throat.

[0021]

According to the present invention, the taste and throat irritation of a dentifrice containing salt and a fluorine compound are improved.
