Abstract
Description
Technical Field
[0001] The invention relates to the technical field of oral care, in particular to an oral care composition and toothpaste for removing oral odor, and a preparation method thereof. Background Art
[0002] Bad breath and bad breath are problems that exist widely in daily life. Whether it is work, social or personal mental health, they may have adverse effects. According to survey statistics, the prevalence of bad breath in China is as high as 27.5%, while in Western countries it is 50%. About 10% to 65% of people in the world have suffered from bad breath. Bad breath not only affects the patient's self-confidence and social interaction, but may also mask the existence of underlying health problems, such as oral diseases or digestive system diseases. The main cause of bad breath and bad breath is that harmful bacteria in the mouth decompose nutrients to produce volatile sulfides such as hydrogen sulfide and methyl mercaptan. These anaerobic bacteria reproduce in the oral environment, especially in the presence of diseases such as gingivitis and periodontitis, and are more likely to breed and release a corrupt smell. In addition, smoking, drinking, and eating spicy or strong-smelling foods can also cause bad breath.
[0003] At present, most products on the market for freshening breath achieve the purpose of temporarily covering up bad breath and freshening breath by adding odor-covering ingredients, rather than solving the problem of bad breath from the root. For example, flavor ingredients such as peppermint oil can only temporarily cover up bad breath in the mouth, and cannot achieve the effect of long-term inhibition of bad breath in the mouth. Although some products containing antibacterial ingredients can effectively inhibit bacterial growth, long-term use may lead to an imbalance in the oral microbial community and may even have adverse effects on health. In addition, although traditional tea-containing lozenges or activated carbon toothpastes have a certain adsorption effect, due to their limited adsorption capacity and the fact that their adsorption capacity is easily saturated during the preparation process, they cannot continuously and effectively remove bad breath in the mouth. It can be seen that the existing solutions are mostly symptomatic and fail to truly solve the problem of bad breath in the mouth.
[0004] In view of the above-mentioned deficiencies in the prior art, it is necessary to develop an oral care product that can solve the problem of bad breath from the root. Summary of the invention
[0005] In order to solve the problem of bad breath in the mouth from the root, the present application provides an oral care composition and toothpaste for removing bad breath in the mouth, and a preparation method. The present application solves the problem of bad breath in the mouth from the source by compounding a composition made of four raw materials: phthalimidoperoxycaproic acid, cetylpyridinium chloride, Lamiophora extract, and tea extract. On the one hand, the composition reacts with volatile sulfides such as hydrogen sulfide and methyl mercaptan to remove the generated bad breath. On the other hand, the composition has a significant bactericidal and antibacterial effect to inhibit the generation of bad breath in the mouth, thereby achieving the purpose of long-term and effective control of bad breath in the mouth.
[0006] In the first aspect, the oral care composition for removing bad breath provided in the present application adopts the following technical scheme: an oral care composition for removing bad breath, comprising the following raw materials in parts by weight: 8 to 10 parts of phthalimidoperoxycaproic acid, 0.1 to 0.5 parts of cetylpyridinium chloride, 0.1 to 0.5 parts of Lamiaceae extract, and 0.1 to 0.5 parts of tea extract.
[0007] In the above technical scheme, the present application selects relatively stable phthalimidoperoxycaproic acid as the main ingredient of the oral care composition for removing oral odor. Phthalimideperoxycaproic acid is an organic compound containing a peroxy (-OOH) functional group. Its chemical formula is C6H5C(O)NHOOC(O)C6H5, and its structure contains two benzene rings, and two acyl groups are connected to an iminoperoxy group (NHOOC(O)). Such a unique molecular structure makes phthalimidoperoxycaproic acid a relatively stable peroxide, which can be used as an oxidant to react with volatile sulfides such as hydrogen sulfide and methyl mercaptan to remove odor. At the same time, the peroxide group in phthalimidoperoxycaproic acid can release active oxygen, which has a certain oxidative bactericidal effect.
[0008] Furthermore, the present application adds Lamiophora extract and tea extract on the basis of phthalimidoperoxycaproic acid as the main ingredient. The Lamiophora extract is rich in flavonoids and can effectively inhibit the growth and reproduction of bacteria. The tea extract is rich in active ingredients such as tea polyphenols, aromatic oils, minerals, amino acids, vitamins, etc., and has inhibitory effects on Staphylococcus aureus, Escherichia coli, Streptococcus mutans, etc. The present application compounds phthalimidoperoxycaproic acid, Lamiophora extract and tea extract. The active oxygen released by phthalimidoperoxycaproic acid during storage will react with active substances such as tea polyphenols and flavonoids, thereby effectively solving the technical problem that products containing phthalimidoperoxycaproic acid are prone to flatulence during long-term storage, thereby ensuring the stability of the oral care composition for removing oral odor.
[0009] Furthermore, the present application adds cetylpyridinium chloride on the basis of phthalimidoperoxycaproic acid as the main ingredient. Cetylpyridinium chloride is a powerful broad-spectrum antibacterial agent, and its antibacterial mechanism mainly interferes with the synthesis of bacterial cell walls to achieve a bactericidal effect. The present application uses phthalimidoperoxycaproic acid, cetylpyridinium chloride, Lamiophaga extract, and tea extract to compound, and these raw materials act on oral microorganisms from different mechanisms, and cetylpyridinium chloride weakens the cell wall or cell membrane of oral microorganisms, thereby increasing the permeability of oral microorganisms, so that phthalimidoperoxycaproic acid, Lamiophaga extract, and tea extract can better penetrate into the interior of the microorganism, and exert better antibacterial and bactericidal effects.
[0010] Furthermore, the present applicant has discovered through experiments that the compounding of phthalimidoperoxycaproic acid, cetylpyridinium chloride, Lamiophora extract and tea extract also enables the oral care composition for removing oral odor to have better gum protection effect. The present applicant has specifically analyzed that this is because the oxidizing effect of phthalimidoperoxycaproic acid can remove pigmentation on the surface of teeth, while the antibacterial effect of cetylpyridinium chloride helps to reduce gingival inflammation, and the antioxidant components in Lamiophora extract and tea extract help to protect gum health. The combination of these four raw materials can jointly exert a synergistic effect and further provide the additional effect of gum protection, thereby achieving the effect of comprehensively improving the oral environment and maintaining the health of teeth.
[0011] Preferably, the raw materials are included in the following parts by mass: 9 parts of phthalimidoperoxycaproic acid, 0.5 parts of cetylpyridinium chloride, 0.3 parts of Lamiophora officinalis extract, and 0.2 parts of tea extract.
[0012] In the above technical scheme, the present application can more effectively inhibit and kill harmful bacteria in the oral cavity, reduce the production of volatile sulfides such as hydrogen sulfide and methyl mercaptan, and thus achieve the purpose of long-term control of oral odor by further optimizing the dosage of phthalimidoperoxycaproic acid, cetylpyridinium chloride, Lamiophora extract, and tea extract.
[0013] In a second aspect, the preparation method of the oral care composition for removing oral odor provided in the present application adopts the following technical scheme: A method for preparing an oral care composition for removing oral odor comprises: mixing phthalimidoperoxycaproic acid, cetylpyridinium chloride, Lamiophora sibiricum extract and tea extract at 20-40 DEG C and stirring evenly to obtain the oral care composition for removing oral odor.
[0014] In the above technical solution, the present application prepares an oral care composition for removing oral odor by mixing and stirring the above raw materials evenly. Such a preparation method is simple and easy and suitable for industrial production.
[0015] In the third aspect, the toothpaste for removing oral odor provided by the present application adopts the following technical solution: A toothpaste for removing bad breath in the mouth comprises the oral care composition for removing bad breath in the mouth as described in the first aspect.
[0016] Preferably, the oral care composition for removing oral odor is added in an amount of 0.5% to 3% in toothpaste.
[0017] In the above technical solution, the present application adds an oral care composition for removing oral odor to toothpaste, thereby giving the toothpaste the function of removing oral odor and protecting gums. The oral care composition for removing oral odor is added in an amount of 0.5% to 3% in the toothpaste, and such an amount can ensure that the toothpaste effectively removes oral odor during use, while not negatively affecting the taste and use experience of the toothpaste.
[0018] Preferably, the toothpaste for removing bad breath comprises the following components in percentage by mass: 55% to 59% sorbitol, 2% to 5% glycerol, 2% to 5% propylene glycol, 0.5% to 0.8% cellulose gum, 0.1% to 0.3% xanthan gum, 0.1% to 0.3% Chondrus crispus extract, 18% to 22% hydrated silica, 1% to 3% sodium lauryl sulfate, 0.1% to 0.3% sodium saccharin, 0.1% to 0.3% sodium benzoate, 0.5% to 1.5% flavor, 0.5% to 3% oral care composition for removing bad breath, and the balance is water.
[0019] Preferably, the toothpaste for removing bad breath comprises the following components in percentage by mass: 57% sorbitol, 3% glycerin, 3% propylene glycol, 0.6% cellulose gum, 0.2% xanthan gum, 0.2% Chondrus crispus extract, 20% hydrated silica, 2% sodium lauryl sulfate, 0.2% sodium saccharin, 0.2% sodium benzoate, 1% flavor, 3% oral care composition for removing bad breath, and the balance is water.
[0020] In the above technical solution, the present application provides a toothpaste formula containing an oral care composition for removing oral odor, such a toothpaste can not only effectively remove oral odor, but also has the additional effect of protecting gums. By adding an appropriate amount of the oral care composition, the toothpaste can play a synergistic role, thereby providing a more comprehensive oral care effect.
[0021] In a fourth aspect, the present application provides a method for preparing a toothpaste for removing bad breath, which adopts the following technical scheme: A method for preparing a toothpaste for removing bad breath, comprising the following steps: Step 1: Start the vacuum pump valve, adjust the vacuum degree to ≥-0.06Mpa, open the feed valve, and dissolve sodium saccharin and sodium benzoate in water; Step 2: Add sorbitol, glycerol and propylene glycol to the material obtained in step 1 and mix well; Step 3: Adjust the vacuum degree to ≥-0.08Mpa, start slow stirring, slowly add cellulose gum, xanthan gum, Chondrus crispus extract, hydrated silica, and sodium lauryl sulfate to the material obtained in step 2, and continue stirring until the mixture is evenly mixed; Step 4: Add essence and oral care composition for removing oral odor to the material obtained in step 3, and continue stirring until the mixture is uniform; Step 5: vacuum the material obtained in step 4 until the paste is uniform and fine, thereby obtaining a toothpaste for removing bad breath.
[0022] In the above technical scheme, the present application obtains a toothpaste with a stable and delicate paste through the above preparation method. Such toothpaste can not only ensure the uniform distribution of the oral care composition in the toothpaste, thereby exerting the best cleaning and care effects, but also can be better dissolved during use and easy to wash.
[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. The present application achieves the effect of removing the produced odor by reacting phthalimidoperoxycaproic acid with volatile sulfides such as hydrogen sulfide and methyl mercaptan. The joint action of phthalimidoperoxycaproic acid, cetylpyridinium chloride, ophiopogon uniflorum extract, and tea extract can effectively inhibit harmful bacteria in the oral cavity, reduce the production of volatile sulfides such as hydrogen sulfide and methyl mercaptan, and thus achieve the purpose of long-term control of oral odor. At the same time, the joint action of phthalimidoperoxycaproic acid, cetylpyridinium chloride, ophiopogon uniflorum extract, and tea extract can also play an additional role in protecting the gums and provide a better oral care effect.

[0062] 1. Verification of the antibacterial effect of an oral care composition for removing oral odor Bacterial suspensions of Escherichia coli (ATCC 25922), Staphylococcus aureus (ATCC 6538), Porphyromonas gingivalis (ATCC 33277), and Streptococcus mutans (ATCC 25175) were prepared (the number of bacteria was 1×10 4 ~9×10 4 CFU / mL).
[0063] Refer to the detection method specified in 2.1.11.3.2 Dissolution Antibacterial (Inhibitory) Product Inhibitory Performance Test Method of Disinfection Technical Specification (2002 Edition). Dilute the oral care composition for removing oral odor of Examples 1 to 3 and Comparative Examples 1 to 5 at a ratio of 1:1, and apply for 5 minutes. When the inhibition rate is ≥50%, it represents effective inhibition, and when the inhibition rate is ≥90%, it represents strong inhibition. The above test results are shown in Table 1.
[0064] Table 1: As can be seen from Table 1, the oral care compositions of Examples 1 to 3 all showed strong antibacterial effects on Escherichia coli, Staphylococcus aureus, Porphyromonas gingivalis and Streptococcus mutans, and the antibacterial rates were all higher than 95%, which shows that the oral care compositions of the present application have a good effect in inhibiting harmful bacteria in the oral cavity.
[0065] 2. Verification of the effectiveness of toothpaste for removing oral odor 90 subjects with oral halitosis and gingivitis were selected and randomly divided into 9 groups, with 10 subjects in each group, and used the toothpastes of application examples 1 to 4 and comparative application examples 1 to 5 respectively. The subjects brushed their teeth twice a day, morning and evening, using 2g of toothpaste each time. The oral conditions of the subjects were examined before and after using the toothpaste for 4 weeks.
[0066] VSC (volatile sulfur compounds): The subjects' bad breath was tested according to the instructions for use of the Halimeter halitosis meter. VSC ≥ 125 ppb indicated the presence of bad breath.
[0067] GI (Gum Index): 0 means healthy gums; 1 means mild gingival inflammation, with slight changes in gum color and mild edema, and no bleeding on probing; 2 means moderate gingival inflammation, with red gums, shiny edema, and bleeding on probing; 3 means severe gingival inflammation, with obvious redness and swelling or ulcers on the gums, and a tendency to spontaneous bleeding; 9 means unable to check, and X means missing.
[0068] BOP (Bleeding on Probing Percentage): The percentage of sites that bleed on probing to the total number of sites examined.
[0069] The above test results are shown in Table 2.
[0070] Table 2: It can be seen from Table 2 that after using the toothpaste of Application Examples 1 to 4, the VSC value of the subjects was significantly reduced, indicating that the toothpaste for removing oral odor of the present application has an improvement effect on oral odor; at the same time, the GI and BOP values are also improved, indicating that the toothpaste for removing oral odor of the present application has a relief effect on gingivitis.
[0071] Specifically combining the analysis of Application Example 1 and Comparative Application Examples 1 to 5, it can be seen that Application Example 1 has a better effect of improving bad breath and relieving gingivitis. It can be seen that phthalimidoperoxycaproic acid, cetylpyridinium chloride, Lamiophora extract and tea extract have a synergistic effect. Only the combination of phthalimidoperoxycaproic acid, cetylpyridinium chloride, Lamiophora extract and tea extract can play a good role in improving bad breath and relieving gingivitis.
