DETAILED DESCRIPTION

[0021] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0023] A whitening tooth cleaning tablet, the raw material of which includes butterfly pea flower extract. This solution innovatively introduces butterfly pea (Clitoria ternatea) flower extract into the whitening tooth cleaning tablet. In addition to its conventional anti-inflammatory and antioxidant effects, the butterfly pea flower extract itself has purple color and also has the property of whitening teeth. When added to the raw materials of the whitening tooth cleaning tablet, the tablet's whitening effect on teeth is significantly improved.

[0024] Furthermore, the whitening and cleaning tablets further comprise the following raw materials: a pH regulator, a moisturizer, a cleaning abrasive, a surfactant, a conditioner, an anti-glycation agent, a whitening agent, a molding agent, and a release agent.

[0025] In addition to butterfly pea flower extract, the formula of the whitening tooth cleaning tablets also introduces pH regulators, moisturizers, cleaning abrasives, surfactants, conditioners, anti-glycation agents, whitening agents, forming agents and release agents. By compounding the above raw materials in multiple directions, the whitening tooth cleaning tablets produced have better whitening effects and can ensure fresh breath for more than 12 hours.

[0026] Furthermore, the whitening and cleaning tooth tablets further comprise at least one of the following raw materials: a cooling agent, a sweetener, a preservative, a fragrance, and a colorant.

[0027] The raw materials of whitening tablets can also be supplemented with sweeteners, preservatives, fragrances, and colorants as needed. Sweeteners can improve the taste of the tablets; fragrances can impart a specific aroma; preservatives can extend the shelf life of the tablets; and colorants can be added to the tablets to create other colors beyond a single white color.

[0028] Furthermore, the whitening tooth cleaning tablets include the following raw materials, measured by mass percentage: 5-30% pH regulator, 1-50% moisturizer, 10-15% cleaning abrasive, 2-10% surfactant, 17-40% forming agent, 0.1-1.6% conditioner, 0.1-1% anti-glycation agent, 1-5% whitening agent, 0.2-2.0% butterfly pea flower extract, 1-5% release agent, 0.1-1% cooling agent, 0.2-2% sweetener, 0.1-0.5% preservative, 0.1-1% fragrance and 0.01-0.3% colorant.

[0029] The above is the preferred formula of whitening and cleaning teeth tablets. The whitening and cleaning teeth tablets made by mixing the raw materials according to the above ratio have good breath freshening and whitening performance.

[0030] Furthermore, the whitening agent is phthalimide peroxycaproic acid; the cleaning abrasive is hydrated silica; the conditioning agent is at least one of sodium calcium phosphosilicate, lactobacillus or basil oil; and the anti-glycation agent is glucanase.

[0031] In actual production, the whitening agent is phthalimide peroxycaproic acid, which is a peroxy acid but not a peroxide. It does not release hydrogen peroxide and has bleaching and antibacterial effects. It is also a mild breath freshening ingredient. When used together with hydrated silica and dextranase (glucanase), it can effectively remove tooth stains, plaque, whiten and freshen breath.

[0032] In addition, the conditioning agent in this solution can be sodium calcium phosphosilicate, lactobacillus, or basil oil. Basil oil has a calming, analgesic, and soothing effect, while also freshening breath. Lactobacillus can balance oral flora and also freshen breath. Sodium calcium phosphosilicate can repair tooth enamel, fill dental tubules, and has a good anti-sensitivity effect.

[0033] Furthermore, the pH regulator is citric acid and sodium bicarbonate; the moisturizer is mannitol; the surfactant is at least one of sodium lauryl sulfate and sodium lauroyl glutamate;

[0034] The molding agent is at least one of maltodextrin, polyvinyl pyrrolidone, microcrystalline cellulose or polyethylene glycol-150.

[0035] The pH regulators of this solution use citric acid and sodium bicarbonate. Sodium bicarbonate and citric acid generate carbon dioxide when in contact with water, causing the surfactant in the raw materials to produce rich and dense foam, thereby improving the cleaning effect of the surfactant. The physical cleaning effect of hydrated silica combined with the dense foam further enhances the whitening effect. In addition to the function of adjusting pH, citric acid and sodium bicarbonate also have the function of disintegration and rapid dissolution.

[0036] Mannitol is used as a moisturizer during production to maintain the tablet's proper hardness and prevent it from becoming too hard. Maltodextrin, polyvinylpyrrolidone, microcrystalline cellulose, or polyethylene glycol-150 can be used as a molding agent to maintain the tablet's shape and homogeneity.

[0037] Furthermore, the release agent is magnesium stearate; the sweetener is at least one of stevioside and galactose; and the preservative is sodium benzoate.

[0038] Magnesium stearate is used as a release agent, facilitating quick and secure demolding of the whitening tablets during preparation. Stevioside and galactose are used as sweeteners to enhance the tablets' flavor without causing tooth decay. Sodium benzoate is used as a preservative to prevent bacterial growth and extend shelf life.

[0039] The following is the preferred formula for producing whitening teeth tablets:

[0040]

[0041]

[0042] The present invention also provides a method for preparing the whitening and cleaning tooth tablet as described in any one of the above items, comprising the following preparation steps:

[0043] S1. Granulation: According to the mass percentage, the other raw materials other than the fragrance and conditioning agent are mixed and stirred evenly, cooled to 55-65 ° C after heating, and the raw materials are granulated to obtain intermediate granules, and the intermediate granules are dehumidified, dried, and sieved to obtain granules;

[0044] S2. Mixing: Add fragrance and conditioner to the granular material, mix and stir evenly, and press into tablets to obtain the whitening and cleaning tablets.

[0045] The whitening tablets in this protocol utilize a combination of polyethylene glycol-150 and wet granulation during the formulation process. The tablets are first granulated. All ingredients in the formula, excluding the fragrance and conditioner, are mixed evenly. Heat-treated, cooled to 60°C, and then granulated using a rotary granulator. The granules are then spread out on a dedicated tray and placed in a dehumidification room for 15 minutes. After drying, they are passed through a vibrating screen and continue to be dehumidified until the humidity reaches the required level before use. The granules are then mixed evenly with the fragrance and conditioner, and pressed into tablets to produce the whitening tablets.

[0046] Furthermore, the heating temperature in step S1 is 70-85°C, and the pellets are dried at room temperature (typically 25±5°C). The pellet preparation temperature is controlled within a range of 70-85°C. Within this temperature range, the raw materials remain stable during the production process. The subsequent drying process removes excess water from the whitening tablets, which are then dried at room temperature. The dried tablets have a moisture content of 0.3-3.0% and an appropriate hardness.

[0047] Furthermore, the granules are sieved through a 15-mesh sieve in step S1. Before being mixed with the fragrance and conditioner, the granules are further sieved through a 15-mesh sieve. The sieve allows particles with a diameter of 0.9 mm to pass through, resulting in a uniform size distribution, which facilitates mixing of the granules with the conditioner and fragrance, and ensures that the resulting whitening and cleaning tablets have good quality.

[0048] The technical solutions of the present invention are further described in detail below in conjunction with specific embodiments. It should be understood that the following embodiments are only used to explain the present invention and are not used to limit the present invention.

[0065] The tooth cleaning tablets of Comparative Example 1 and the whitening tooth cleaning tablets prepared in Examples 1 to 4 were subjected to the following performance tests:

[0066] Methyl mercaptan test results

[0067]

[0068] Note: The experimental design and method for the above-mentioned methyl mercaptan detection are as follows:

[0069] 1. Experimental grouping: This experiment set up sample groups, with 4 parallel experiments in each group.

[0070] 2. Biofilm Pre-incubation: Place a HAP tablet in each of eight 15mL centrifuge tubes, add 2mL of fresh saliva, cover, and incubate in a 37°C water bath for 24 hours. Dissolve 0.3g of thioglycollate medium in 10mL of deionized water. Prepare a breath-breathing simulation solution using a ratio of thioglycollate medium: deionized water: fresh saliva of 2:13:85.

[0071] 3. Sample Contact: Grind the toothpaste particles and dilute them with deionized water at a ratio of 1:1.6 (toothpaste:deionized water). Mix thoroughly and set aside. Remove the HAP discs that have been incubated overnight and place them in a 12-well plate, one disc per well. Randomly group the discs into groups of four. Add the samples to the 12-well plate according to the experimental group and allow them to react for 3 minutes. Remove the HAP discs and transfer them to a headspace vial. Add 2 mL of breath-generating simulant solution, seal the vial, and incubate in a 37°C water bath for 12 hours.

[0072] 4. Determination of methyl mercaptan production: Use gas chromatography to detect methyl mercaptan in the headspace vial to evaluate the breath freshening effect of the sample.

[0073] 5. Data processing: Based on the experimental data, calculate the mean (Mean), standard deviation (SD) and coefficient of variation (CV) of each treatment group.

[0074] 6. The standard deviation in the table above indicates the degree to which each value in the data set deviates from the mean. A larger value indicates greater dispersion within the data set, while a smaller value indicates less dispersion. The coefficient of variation, equal to the standard deviation divided by the mean, is a dimensionless number that can be used to compare the dispersion of populations with significantly different means. It can eliminate the effects of unit and / or mean differences on the comparison of the variation between two or more data points. When conducting statistical analysis, if the coefficient of variation is greater than 15%, the data may be considered abnormal and should be excluded.

[0075] Results of removing exogenous stains

[0076]

[0077] Changes in whiteness value ΔL within 30 days

[0078]

[0079]

[0080] Note: The experimental method is:

[0081] 1. Prepare dental grinding blocks: Cut bovine incisors into enamel blocks approximately 5 mm × 5 mm × 2 mm and embed them in polymethyl methacrylate resin. Polish the labial surface of the enamel using water-moistened 180-grit sandpaper, smoothing the curved enamel surface. Rinse the sample with water and then polish the enamel surface smooth using water-moistened 600-grit sandpaper. Rinse the sample in deionized water in an ultrasonic bath for 15 minutes.

[0082] 2. Acid etching: Immerse the tooth grinding block in 1% hydrochloric acid, stir for 60 seconds, remove and rinse with clean water; then immerse it in saturated sodium carbonate solution, stir for 60 seconds, remove and rinse with clean water; finally immerse it in 1% phytic acid solution, stir for 60 seconds, remove and rinse with clean water.

[0083] 3. Prepare the staining solution: First, dissolve gastric mucin in hot water. Then, add coffee, soy sauce, and black tea, stir thoroughly, and let cool. Add FeCl₃ solution stored at 4°C before use. The final concentrations of each component are: gastric mucin 2.5 g / L, coffee 4.0 g / L, soy sauce 4.0 g / L, black tea 4.0 g / L, and ferric chloride 0.05 g / L.

[0084] 4. Staining of Tooth Abrasive Blocks: Place the acid-etched tooth abrasive blocks in a staining machine and stain for 12 days. The stained tooth abrasive blocks are numbered and labeled. The enamel color (L* before brushing) is measured using a colorimeter. Blocks with an L* value of 30-50 are selected and randomly assigned to a sample group and a control group, with 8 blocks in each group. Each group is brushed with the test and control substances, respectively.

[0085] 5. Preparation of test sample slurry: Weigh a certain weight of the toothpaste particles (tooth cleaning tablets) to be tested and deionized water in a ratio of 1:1.6 (toothpaste particles: water), stir with a glass rod to disperse the toothpaste particles, and then stir with a magnetic stirrer to form a homogenous slurry for later use.

[0086] 6. Simulated toothbrushing process for the exogenous stain removal test: Place the tooth grinding block into the sample fixing slot of the automatic mechanical toothbrush machine and fix it so that the tooth grinding block is about 2mm higher. Tighten the screws to fix it. Install the toothbrush head so that the bristles are in vertical contact with the enamel surface. The total weight of the toothbrush head and rod is 150g. Weigh about 70g of the sample slurry to be tested and add it to the grinding liquid bottle. Fix the grinding liquid bottle on the toothbrush machine so that the slurry buries the tooth grinding block. Brush your teeth back and forth 800 times. After brushing, remove the tooth grinding block from the toothbrush machine, rinse it with water, dry it with a paper towel, and let it dry.

[0087] 7. The brushing conditions for the whiteness value ΔL within 30 days were set as follows: brushing pressure 150 g ± 20 g; brushing angle 0 degrees horizontal; brushing days / frequency 0-30 days / twice a day.

[0088] 8. Measure the enamel color L* after brushing and calculate the difference in △L* values ​​before and after brushing: L*=L*after brushing-L*before brushing.

[0089] As shown in the test results of Example 1 and Comparative Example 1, after introducing the butterfly pea flower extract into the existing tooth cleaning tablet formula, the effect of removing bad breath and the degree of whitening of teeth are improved to a certain extent. Wherein, the tooth cleaning tablet of Comparative Example 1 does not even have the effect of whitening after being used for 25 days, and the teeth have a tendency to yellow.

[0090] Referring to the test results of the whitening tooth cleaning tablets prepared in Examples 2-4, when the special formula of this solution is used in combination with the butterfly pea flower extract, the breath removal effect and the degree of teeth whitening are greatly improved. Among them, the methyl mercaptan detection result of Example 2 can be reduced to 0, and the whiteness value ΔL of Examples 2-4 can reach more than 27. The use of the whitening tooth cleaning tablets has a good whitening effect on teeth.

[0091] Example 5

[0092] The preparation steps and parameters in this embodiment are the same as those in Example 2, except that the whitening agent is replaced by sodium phytate instead of phthalimide peroxycaproic acid.

[0093] The performance of the whitening and cleaning tablets prepared in Example 5 was tested, and the specific test results are shown in the following table:

[0094] Methyl mercaptan test results

[0095]

[0096] Results of removing exogenous stains

[0097]

[0098] Changes in whiteness value ΔL within 30 days

[0099]

[0100] As shown in the test data in the table above, it can be seen from the test results of Example 2 and Example 5 that the commonly used whitening agent on the market, sodium phytate, is not as effective as phthalimide peroxycaproic acid. When phthalimide peroxycaproic acid is used as the whitening agent of this solution, it has a better breath freshening effect and a better teeth whitening effect.

[0101] Example 6

[0102] The preparation steps and parameters in this embodiment are the same as those in Example 2, except that the specific raw materials of the forming agent are changed, as shown in the following table:

[0103]

[0104] The whitening and cleaning tablets prepared in Example 6 were subjected to performance testing, and the specific test results are shown in the following table:

[0105] Methyl mercaptan test results

[0106]

[0107]

[0108] Results of removing exogenous stains

[0109]

[0110] Changes in whiteness value ΔL within 30 days

[0111]

[0112]

[0113] As shown in the test data in the above table, it can be seen from the test results of Example 2 and Example 6 that the molding agent of this scheme is preferably a combination of maltodextrin, polyvinyl pyrrolidone, microcrystalline cellulose and polyethylene glycol-150 in a certain dosage ratio. In this way, the whitening effect of the whitening tooth cleaning tablet on teeth can be optimized.

[0114] Example 7

[0115] The preparation steps and parameters in this embodiment are the same as those in Example 2, except that the specific addition amount of the butterfly pea flower extract is changed, as shown in the following table:

[0116] Butterfly pea flower extract added Example 2 0.2% Example 7-1 0.005% Example 7-2 0.05% Example 7-3 0.1% Example 7-4 0.5% Example 7-5 1% Example 7-6 1.5% Example 7-7 2%

[0117] The performance of the whitening and cleaning tablets prepared in Example 7 was tested, and the specific test results are shown in the following table:

[0118] Methyl mercaptan test results

[0119]

[0120]

[0121] Results of removing exogenous stains

[0122]

[0123] Changes in whiteness value ΔL within 30 days

[0124]

[0125] As shown in the test data in the above table, it can be seen from the test results of Example 2 and Example 7 that the addition amount of the butterfly pea flower extract in this scheme is further preferably 0.2-2%.
