Shellac was previously dissolved in propylene glycol by heating. Separately, xylitol and polyoxyethylene hydrogenated castor oil were well dispersed in glycerin. Also, methyl paraoxybenzoate dissolved in the fragrance. On the other hand, a solvit solution,
Saccharin sodium and purified water were added and uniformly dissolved and mixed. A propylene glycol solution in which shellac was dissolved and the glycerin dispersion were added thereto and mixed to prepare a uniform solution. Next, after degassing the air contained in this solution, the stirring was stopped once, sodium lauryl sulfate was added, and the mixture was stirred again under reduced pressure to obtain a uniform composition. Finally, the flavor liquid was added and mixed. Thus, a liquid toothpaste composition according to the present invention was produced.

Example 3 Toothpaste Ingredients Weight% Calcium Carbonate 80.0 Shellac 5.0 Fluorinated Oil 0.5 Sodium Lauryl Sulfate 1.2 Flavor 1.0 Sodium Saccharin 0.1 Methyl p-oxybenzoate 0. 1 Sodium benzoate 0.1 Purified water 12.0 Total 100.0 Sodium saccharin, methyl p-oxybenzoate, and sodium benzoate were dissolved in purified water. Calcium carbonate, shellac, fluorinated oil, and sodium lauryl sulfate were put into a mixer, mixed uniformly, and the above aqueous solution and flavor were added to obtain a uniform lubricating toothpaste.

Next, an experiment was conducted to determine the glossiness on the tooth surface. That is, 16 test subjects (9 males and 7 females) were brushed with the dentifrice (A) according to the present invention and the control dentifrice (B) containing no shellac, and the judge 3 having at least 10 years of clinical experience was evaluated. The gloss of the test teeth was visually determined for each name.

Experimental method The test teeth were the upper and lower anterior teeth labial flank. Immediately after three examiners visually observe the condition of the test tooth surface before brushing, place one of them on a toothbrush that the test subject uses daily for about 2 cm, and freely use only the test tooth surface for about 1 minute. Brushed. The judge did not know which dentifrice the subject was using. However, the number of subjects using each dentifrice was the same (8 each). After the end of the brushing, the glossiness of the test tooth surface was judged by three judges. The criterion is that the gloss of the test tooth surface does not change before and after brushing,
There were four types: slightly glossy and clearly glossy.

Results The results of the judgment are shown below.

As a result of the Mann-Whitney test, the risk factor was 1%
In the group using the dentifrice of the present invention (A) and the control dentifrice (B)
There was a statistically significant difference from the use group.

Conclusion The tooth surface after use of the dentifrice (A) of the present invention was judged to be glossier than after use of the control dentifrice (B).

[0029]

When the toothpaste composition according to the present invention is used, it is possible to impart not only the original whiteness to the teeth but also gloss, shine and gloss. Although teeth have a reduced number of blemishes due to numerous scratches on the surface, the use of the toothpaste composition according to the present invention results in the tooth surface being covered with shellac and becoming smooth. For this reason, suppresses irregular reflection of light, glossy teeth,
It is thought that it can give brilliance and luster.

Further, the toothpaste composition of the present invention may contain a fluorinated oil and / or a bactericide.
This can further increase the gloss and the like of the teeth,
The growth of bacteria on the coated teeth can be prevented. That is, the fluorinated oil has an effect of enhancing gloss. In addition, when the teeth are covered with shellac, anaerobic bacteria may propagate in the teeth because the air permeability of the shellac coating is low. However, by including a fungicide, the propagation can be suppressed.
