Description

Composition for eliminating or improving bad breath

[0001] The present disclosure relates to a composition for eliminating or improving bad breath and an oral product comprising the same.

[0002] Bad breath is an odor that comes from the mouth during breathing or conversation. It can be unpleasant to those around you and can affect interpersonal relationships. The causes of bad breath can be broadly divided into internal and external oral causes.

[0003] Oral causes include dental caries, periodontal disease, saliva retention during sleep, consumption of strong-smelling foods, and smoking. Extraoral causes include upper respiratory tract disease, digestive system disease, and medications.

[0004] However, the main cause of bad breath often occurs directly within the oral cavity, and accordingly, interest in methods to eliminate bad breath caused by oral causes is increasing.

[0005] The components of bad breath that occur in the mouth are generally volatile sulfur compounds, which are created when protein substances such as saliva, dental plaque, or food residue are decomposed by oral microorganisms.

[0006] These volatile sulfides are known to be composed of more than 90% hydrogen sulfide and methyl mercaptan, with small amounts of dimethyl sulfide.

[0007] Among them, methyl mercaptan has a more unpleasant odor and lower threshold than hydrogen sulfide in sensory evaluation, so removing methyl mercaptan is considered important for effectively removing and improving bad breath felt during actual breathing.

[0008] However, the current commercially available toothpaste and other cleaning agent compositions have excellent hydrogen sulfide removal performance, but have poor methyl mercaptan removal effect, making them unable to effectively remove bad breath.

[0009] Accordingly, there is a need to develop an oral product that can exhibit excellent bad breath removal effects by removing both hydrogen sulfide and methyl mercaptan, which are the main components of bad breath, at a high rate.

[0010] The present specification is intended to solve the problems of the prior art described above, and one object of the present specification is to provide a composition for removing or improving bad breath, which can exhibit an excellent bad breath removing or improving effect by removing both hydrogen sulfide and methyl mercaptan, which are major components of bad breath, at a high rate.

[0011] Another objective of this specification is to provide an oral product with excellent effects in removing or improving bad breath.

[0012] According to one aspect, a composition for removing or improving bad breath is provided, which comprises zinc salt and essential oil as active ingredients, and the weight ratio of the zinc salt and the essential oil is 1:0.4 to 2.

[0013] In one embodiment, the content of the zinc salt may be 0.1 to 1.0 weight% based on the total weight of the composition.

[0014] In one embodiment, the content of the essential oil may be 0.1 to 0.5 weight percent based on the total weight of the composition.

[0015] In one embodiment, the composition for removing or improving bad breath may further include silicon dioxide.

[0016] In one embodiment, the zinc salt may be one selected from the group consisting of zinc oxide, zinc lactate, zinc chloride, zinc citrate, zinc acetate, zinc borate, zinc butyrate, zinc carbonate, zinc formate, zinc gluconate, zinc glycerate, zinc glycolate, zinc phosphate, zinc picolinate, zinc proprionate, zinc salicylate, zinc silicate, zinc stearate, zinc tartrate, zinc undecylenate, zinc ricinoleate, zinc nitrate, zinc sulfate, and combinations of two or more thereof.

[0017] In one embodiment, the essential oil is selected from the group consisting of grapefruit oil, neroli oil, niauli oil, lavender oil, lime oil, lemon oil, lemongrass oil, lemon balm oil, rose oil, rosemary oil, rosewood oil, linden blossom oil, marjoram oil, mandarin oil, myrtle oil, myrrh oil, violet oil, basil oil, verbena oil, birch oil, bergamot oil, bay oil, vetiver oil, benzoin oil, cypress oil, sandalwood oil, cinnamon oil, cedarwood oil, citronella oil, orange oil, eucalyptus oil, ylang-ylang oil, jasmine oil, geranium oil, juniper berry oil, ginger oil, cardamom oil, chamomile oil, cajuput oil, camphor oil, thyme oil, tangerine oil, tea tree oil, palmarosa oil, patchouli oil, petitgren oil, peppermint oil, frankincense oil, hyssop oil and It may be one selected from a group consisting of two or more combinations of these.

[0018] In one embodiment, the composition for removing or improving bad breath may further include one or more ingredients selected from the group consisting of abrasives, surfactants, humectants, medicaments, and additives.

[0019] According to another aspect, an oral product comprising the above composition for removing or improving bad breath is provided.

[0020] A composition for removing or improving bad breath according to one aspect of the present specification can exhibit an excellent bad breath removing or improving effect by removing both hydrogen sulfide and methyl mercaptan, which are major components of bad breath, at a high rate.

[0021] An oral product according to another aspect of the present specification may exhibit an excellent effect of removing or improving bad breath.

[0022] It should be understood that the effects of one aspect of this specification are not limited to the effects described above, but include all effects that can be inferred from the detailed description or claims of this specification.

[0023] FIGS. 1 to 3 are the results of evaluating the effect of removing or improving bad breath according to one embodiment of the present specification.

[0024] Below, aspects of this specification will be described with reference to the attached drawings. However, the contents of this specification may be implemented in various different forms and are therefore not limited to the embodiments described herein.

[0025] Throughout the specification, whenever a part is said to "include" a component, this does not mean that it excludes other components, but rather that it may include other components, unless otherwise stated.

[0026] When a range of numerical values ​​is stated herein, unless the specific range is otherwise specified, the values ​​have the precision of the significant figures provided according to the standard rules in chemistry for significant figures. For example, the number 10 includes the range of 5.0 to 14.9, and the number 10.0 includes the range of 9.50 to 10.49.

[0027] Hereinafter, an embodiment of the present specification will be described in detail with reference to the attached drawings.

[0028] Composition for eliminating or improving bad breath

[0029] A composition for removing or improving bad breath according to one aspect of the present specification comprises a zinc salt and an essential oil as active ingredients.

[0030] A composition for removing or improving bad breath according to one aspect of the present specification can exhibit excellent bad breath removal or improvement effects by including zinc salt and essential oil, thereby removing both hydrogen sulfide and methyl mercaptan, which are major components of bad breath, at a high rate.

[0031] Unlike the above composition for removing or improving bad breath, a composition containing only essential oils may have low removal performance for both hydrogen sulfide and methyl mercaptan, and in the case of a composition containing only zinc salts, while the removal performance for hydrogen sulfide may be excellent, the removal effect for methyl mercaptan may be poor, making effective removal of bad breath impossible.

[0032] The weight ratio of the zinc salt and the essential oil may be 1:0.4 to 2. For example, it may be 1:0.4, 1:0.5, 1:0.6, 1:0.7, 1:0.8, 1:0.9, 1:1, 1:1.1, 1:1.2, 1:1.3, 1:1.4, 1:1.5, 1:1.6, 1:1.7, 1:1.8, 1:1.9, 1:2, or a range between two of these weight ratios. If the weight ratio of the essential oil to the zinc salt falls outside the above range, the removal rate of hydrogen sulfide and methyl mercaptan is lowered, which may reduce the effect of removing or improving bad breath.

[0033] The content of the zinc salt may be 0.1 to 1.0 wt% based on the total weight of the composition. For example, it may be 0.1 wt%, 0.15 wt%, 0.2 wt%, 0.25 wt%, 0.3 wt%, 0.35 wt%, 0.4 wt%, 0.45 wt%, 0.5 wt%, 0.55 wt%, 0.6 wt%, 0.65 wt%, 0.7 wt%, 0.75 wt%, 0.8 wt%, 0.85 wt%, 0.9 wt%, 0.95 wt%, 1.0 wt%, or a range between any two of these values. If the content of zinc salt is below the above range, the removal rate of hydrogen sulfide and methyl mercaptan may decrease, which may reduce the effect of removing or improving bad breath. If it exceeds the above range, the effect may decrease compared to the content, or damage may be inflicted on the oral mucosa due to pH change caused by acetic acid.

[0034] The content of the above essential oil may be 0.1 to 0.5 wt% based on the total weight of the composition. For example, it may be 0.1 wt%, 0.15 wt%, 0.2 wt%, 0.25 wt%, 0.3 wt%, 0.35 wt%, 0.4 wt%, 0.45 wt%, 0.5 wt%, or a range between any two of these values. If the content of the essential oil is less than the above range, the removal rate of hydrogen sulfide and methyl mercaptan may decrease, thereby reducing the effect of removing or improving bad breath, and if it exceeds the above range, the effect may be reduced relative to the content.

[0035] The above zinc salt may be one selected from the group consisting of zinc oxide, zinc lactate, zinc chloride, zinc citrate, zinc acetate, zinc borate, zinc butyrate, zinc carbonate, zinc formate, zinc gluconate, zinc glycerate, zinc glycolate, zinc phosphate, zinc picolinate, zinc proprionate, zinc salicylate, zinc silicate, zinc stearate, zinc tartrate, zinc undecylenate, zinc ricinoleate, zinc nitrate, zinc sulfate, and combinations of two or more thereof, but is not limited thereto.

[0036] The above essential oils are grapefruit oil, neroli oil, niauli oil, lavender oil, lime oil, lemon oil, lemongrass oil, lemon balm oil, rose oil, rosemary oil, rosewood oil, linden blossom oil, marjoram oil, mandarin oil, myrtle oil, myrrh oil, violet oil, basil oil, verbena oil, birch oil, bergamot oil, bay oil, vetiver oil, benzoin oil, cypress oil, sandalwood oil, cinnamon oil, cedarwood oil, citronella oil, orange oil, eucalyptus oil, ylang-ylang oil, jasmine oil, geranium oil, juniper berry oil, ginger oil, cardamom oil, chamomile oil, cajuput oil, camphor oil, thyme oil, tangerine oil, tea tree oil, palmarosa oil, patchouli oil, petitgren oil, peppermint oil, frankincense oil, hyssop oil, and two of these.

For example, it may be 10 wt%, 15 wt%, 20 wt%, 25 wt%, 30 wt%, or a range between any two of these values. If the content of the abrasive is less than the above range, the tooth surface polishing performance of the composition may be reduced, and if it is more than the above range, the usability of the composition may be reduced.

[0042] The above surfactant refers to a substance that improves the usability and cleansing power of the composition and increases the dispersibility of the active ingredient.

[0080] Experimental Example 1

[0081] In order to evaluate the effect of removing or improving bad breath according to the change in the content of zinc acetate and eucalyptus oil included in the toothpaste composition, an in-vitro experiment using volatile sulfides was performed.

[0082] A 0.001% NaSH hydrogen sulfide gas solution was prepared. 2 g of each of the dentifrice compositions of Examples 1 to 4 and Comparative Examples 3 to 6 was mixed with 20 ml of purified water to prepare a dentifrice. 5 ml of the dentifrice was added to 20 ml of the hydrogen sulfide gas solution in a test tube, sealed with a rubber stopper, and stirred to measure the hydrogen sulfide gas concentration over time using an OralChroma device.

[0083] Each hydrogen sulfide gas concentration was calculated as a percentage of the gas concentration of the hydrogen sulfide gas solution without the addition of dentifrice, and each measurement was performed three times to calculate the average value. The results are shown in Table 1 below.

[0085] Referring to Table 1, it was confirmed that the detergent composition of Comparative Example 4 containing 0.1 wt% of zinc acetate had a lower hydrogen sulfide gas removal rate than the detergent compositions of Comparative Examples 3, 5, and 6 containing 0.3 wt% or more of zinc acetate, and thus the effect of removing or improving bad breath was significantly lower.

[0086] The dentifrice compositions of Examples 1 to 4, which contained both zinc acetate and eucalyptus oil, all exhibited high hydrogen sulfide gas removal rates, demonstrating excellent halitosis removal or improvement effects. In particular, all examples exhibited hydrogen sulfide gas removal rates of 99% or higher after 60 minutes, and all examples exhibited 100% after 120 minutes.

[0087] In addition, the detergent compositions of Examples 1, 3 and 4 using 0.2 wt% or more of eucalyptus oil together with 0.3 wt% of zinc acetate showed excellent effects with a hydrogen sulfide gas removal rate of 97% or more in all time ranges.

[0088] Experimental Example 2

[0089] The bad breath removal or improvement effect of the dentifrice composition was evaluated in the same manner as in Experimental Example 1, except that the hydrogen sulfide gas solution was changed to an artificial bad breath (hydrogen sulfide + methyl mercaptan gas) solution containing 0.001% NaSH and 0.0002% NaSCH3 in a ratio of 7:3. The results are shown in Table 2 below.

[0091] Referring to Table 2, it was confirmed that the dentifrice composition of Comparative Example 4 containing 0.1 wt% of zinc acetate had a lower hydrogen sulfide and methyl mercaptan gas removal rate than the dentifrice compositions of Comparative Examples 3, 5, and 6 containing 0.3 wt% or more of zinc acetate, and thus the bad breath removal or improvement effect was significantly lower.

[0092] It was confirmed that the toothpaste compositions of Examples 1 to 4, which contain both zinc acetate and eucalyptus oil, all exhibited excellent bad breath removal or improvement effects, with higher removal rates of hydrogen sulfide and methyl mercaptan gas compared to the toothpaste compositions of Comparative Examples 3 to 6, which do not contain eucalyptus oil. In particular, after 60 minutes, all examples showed a removal rate of 95% or more of hydrogen sulfide and methyl mercaptan gas, and after 120 minutes, all examples showed a removal rate of 98% or more of hydrogen sulfide and methyl mercaptan gas.

[0093] In addition, the detergent compositions of Examples 1, 3 and 4 using 0.2 wt% or more of eucalyptus oil together with 0.3 wt% of zinc acetate showed excellent effects with hydrogen sulfide and methyl mercaptan gas removal rates of 90% or more in all time ranges.

[0095] In-vitro experiments using volatile sulfides were conducted to evaluate the bad breath removal or improvement effect of the toothpaste composition.

[0096] A hydrogen sulfide gas solution of 0.001% NaSH was prepared. 2 g of the toothpaste compositions of Example 1 and Comparative Examples 1 and 2 were each mixed with 20 ml of purified water to prepare a toothpaste solution. 5 ml of the toothpaste solution was added to 20 ml of the hydrogen sulfide gas solution contained in a test tube, sealed with a rubber stopper, and the hydrogen sulfide gas concentration over time was measured using an OralChroma instrument while stirring.

[0097] For comparison, the gas concentration of hydrogen sulfide gas solution without toothpaste was also measured (control group). Each measurement was performed three times, and the average value was calculated. The results are shown in Table 3 and Figure 1.

[0099] Referring to Table 3 and Figure 1, the toothpaste composition of Example 1 containing both zinc acetate and eucalyptus oil removed 100% of hydrogen sulfide gas, and it was confirmed that the hydrogen sulfide gas concentration was 0 ppb from immediately after adding the toothpaste to the hydrogen sulfide gas solution until 60 minutes later.

[0100] On the other hand, when the toothpaste composition of Comparative Example 1, which does not contain both zinc acetate and eucalyptus oil, was used, a hydrogen sulfide gas concentration similar to that of the hydrogen sulfide gas test solution (control group) without added toothpaste was detected, confirming that there was no effect of removing or improving bad breath. In addition, the toothpaste composition of Comparative Example 2, which does not contain zinc acetate, showed a hydrogen sulfide gas removal effect of 10 to 40 percent, confirming that the effect of improving bad breath was poor.

[0101] Experimental Example 4

[0102] The bad breath removal or improvement effect of the dentifrice composition was evaluated in the same manner as in Experimental Example 3, except that the hydrogen sulfide gas solution was changed to an artificial bad breath (hydrogen sulfide + methyl mercaptan gas) solution containing 0.001% NaSH and 0.0002% NaSCH3 in a ratio of 7:3. The results are shown in Table 4 and Fig. 2 below.

[0104] Referring to Table 4 and Figure 2, it was confirmed that the toothpaste composition of Example 1 containing both zinc acetate and eucalyptus oil had an excellent effect in removing or improving bad breath, with a hydrogen sulfide and methyl mercaptan gas removal rate of 83% or more.

[0105] On the other hand, when the dentifrice composition of Comparative Example 1, which did not contain either zinc acetate or eucalyptus oil, was used, concentrations of hydrogen sulfide and methyl mercaptan gases were detected at levels similar to those of the artificial bad breath solution (control group) without the addition of dentifrice, confirming that there was no effect in removing or improving bad breath. In addition, the dentifrice composition of Comparative Example 2, which did not contain zinc acetate, showed a hydrogen sulfide and methyl mercaptan gas removal effect of 20 to 40%, confirming that the effect in improving bad breath was poor.

[0106] Experimental Example 5

[0107] In-vivo experiments were conducted to evaluate the effect of the toothpaste composition on removing or improving bad breath.

[0108] Each subject gargled with a 3 mM L-cysteine ​​solution for at least 30 seconds and waited for 4 minutes, after which the concentration of volatile sulfur compounds (VSC) in the oral cavity was measured. Subsequently, the subjects brushed their teeth with the toothpaste compositions of Example 1 and Comparative Examples 1 and 2, respectively, and the concentration of VSC in the oral cavity was measured after 1 hour.

[0109] The oral VSC concentration was measured by inserting a 1 mL syringe into the mouth to approximately 0.8 mL, fixing it using the front teeth, applying pressure to the lips to block external air inflow as much as possible, capturing gas for approximately 1 minute, pumping the syringe 2-3 times, withdrawing it, and inserting the syringe into the OralChroma device with the piston set to 1.0 mL.

[0110] The percentage of VSC concentration after 1 hour of rinsing relative to the VSC concentration before rinsing was calculated, and the average value was calculated by conducting the experiment on 10 subjects. The results are shown in Table 5 and Figure 3 below.

[0111] VSC concentration (%) after 1 hour of brushing Example 18.5 Comparative Example 110.5 Comparative Example 29.9

[0112] Referring to Table 5 and Figure 3, the VSC reduction rate after 1 hour of brushing with the toothpaste composition of Example 1 containing both zinc acetate and eucalyptus oil was 91.5%, confirming that the effect of removing or improving bad breath and its maintenance were excellent.

[0113] On the other hand, it was confirmed that the detergent composition of Comparative Example 1, which did not contain either zinc acetate or eucalyptus oil, and the detergent composition of Comparative Example 2, which did not contain zinc acetate, had lower VSC reduction and maintenance effects compared to Example 1.

[0114] Experimental Example 6

[0115] To evaluate the satisfaction, purchase intention, preference, and bad breath removal or improvement effect of the toothpaste compositions when actually used, a sensory evaluation of the toothpaste compositions of Example 1 and Comparative Example 2 was conducted on 75 subjects. The results are shown in Table 6 below.

[0116] Classification (No.) Example 1 Comparative Example 2 Satisfaction 50 25 Purchase Intention 50 25 Scent Preference 51 24 Residual Feeling Preference 45 30 Usability Preference 47 28 Bad Breath Removal Effect 47 28
