As shown in Table 3, a decrease in the components causing bad breath was generally observed in all of the Examples. Specifically, in Examples 1 and 2 coated with malic acid, the component reduction effect of hydrogen sulfide and dimethyl sulfide was substantially absent. However, it was possible to confirm a significant decrease in the methyl mercaptan component.

Considering the general tendency that the lower the threshold index, the higher the contribution to odor generation (the TIs of methyl mercaptan, hydrogen sulfide and dimethyl sulfide are 0.07 ppb, 0.4 ppb, and 3.0 ppb, respectively), practically only methyl mercaptan reduction properties are confirmed It is expected that a substantial reduction in bad breath can be expected even in the case of the malic acid coating.

On the other hand, in the case of Examples 3 and 4 coated with grapefruit seed extract, all the components that cause bad breath generally showed a tendency to decrease, and in particular, hydrogen sulfide and methyl mercaptan components showed a very large reduction rate, so that sucralose or It was confirmed that the coating with grapefruit seed extract was the most excellent in terms of the effect of reducing bad breath.

Experimental Example 3: Test results for reducing harmful bacteria according to functional material coating

In order to evaluate the effect of reducing harmful bacteria in each Example, a reduction rate test of Streptococcus mutans in the oral cavity was conducted by requesting the Korea Standards Test Institute, and the results are summarized in Table 4 below. 3 is a photograph that can visually confirm the harmful bacteria reduction action in Comparative Examples 1, 2 and 4, and FIGS. 4 to 7 are test reports for Examples 2, 4, 5, 14, and 15, respectively.

On the other hand, in the test, mutans bacteria were absorbed in tip paper coated with each functional material for 18 hours, and then recovered and cultured again, and the reduction rate of mutans bacteria compared to the control not coated with the functional material was measured.

division decrease rate No. coating material Coating amount Example 2 malic acid 5.0% 80.1% Example 4 Grapefruit Seed Extract 7.0% 50.2% Example 5 malic acid + sucralose 5.0%+0.9% 98.1% Example 14 rosemary oil 5.0% 44.0% Example 15 sucralose 5.0% 64.7%

Referring to Table 4 and FIGS. 3 to 7, it can be seen that, in all of Examples 2, 4, 5, 14, and 15, excellent mutans reduction rates were shown. Specifically, Example 2 coated with 5% malic acid In the case of mutans, a reduction effect of 80% or more was observed, and a reduction rate of about 50% was observed in Example 4 coated with 7% grapefruit seed extract, and about 44% of Example 14 coated with rosemary oil 5%. A reduction rate was observed, and in Example 15 coated with 5% sucralose, a reduction rate of about 65% was also observed. In particular, in the case of Example 5 coated with 5% malic acid and 0.9% sucralose, a reduction rate of about 98% was observed, confirming very excellent performance in terms of reducing harmful bacteria.

Through the above results, when the tip paper coated with the above-described functional materials comes into contact with the user's lips, it is possible to expect the effect of reducing harmful bacteria on the bacteria present in the oral cavity.

Those of ordinary skill in the art related to the present embodiment will understand that it can be implemented in a modified form within a range that does not deviate from the essential characteristics of the above description. Therefore, the disclosed methods are to be considered in an illustrative rather than a restrictive sense. The scope of the present invention is indicated in the claims rather than the foregoing description, and all differences within the scope equivalent thereto should be construed as being included in the present invention.
