DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work 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 it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0023] A whitening and cleaning tooth tablet, the raw materials of which include butterfly pea flower extract. This solution innovatively introduces butterfly pea (CLITORIA TERNATEA) flower extract into the whitening and cleaning tooth tablet. In addition to its conventional anti-inflammatory and antioxidant effects, the butterfly pea flower extract itself has a purple color and also has the property of whitening teeth. After adding it to the raw materials of the whitening and cleaning tooth tablet, the whitening effect of the tooth tablet on teeth is significantly improved.

[0024] Furthermore, the whitening and cleaning tooth tablets also include the following raw materials: pH regulator, moisturizer, cleaning abrasive, surfactant, conditioner, anti-glycation agent, whitening agent, molding agent and release agent.

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

[0026] Furthermore, the whitening and cleaning tooth tablets also include 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 and cleaning teeth tablets can also be added with sweeteners, preservatives, fragrances and colorants as needed. Among them, sweeteners can improve the taste of whitening and cleaning teeth tablets when they are taken in the mouth; fragrances can make whitening and cleaning teeth tablets have a specific fragrance; preservatives can extend the storage period of whitening and cleaning teeth tablets; after adding colorants, whitening and cleaning teeth tablets can be adjusted to other colors instead of a single white color.

[0028] Furthermore, the whitening tooth cleaning tablets include the following raw materials, measured by mass percentage: 5-30% pH adjuster, 1-50% moisturizer, 10-15% cleaning abrasive, 2-10% surfactant, 17-40% molding 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 tooth tablets. The whitening and cleaning tooth tablets prepared 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 dextranase.

[0031] In actual production, the whitening agent is phthalimide peroxycaproic acid, which is a peroxy acid non-peroxide and does not release hydrogen peroxide. It 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 of this scheme can be sodium calcium phosphosilicate, lactobacillus or basil oil. Among them, basil oil has sedative, analgesic and soothing effects, and also has the effect of refreshing breath; lactobacillus can balance the oral flora and also refresh the breath; sodium calcium phosphosilicate can be used to 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 scheme use citric acid and sodium bicarbonate. Sodium bicarbonate and citric acid generate carbon dioxide when they meet water, which makes the surfactant in the raw materials produce rich and dense foam, thereby improving the cleaning effect of the surfactant. The physical cleaning effect of hydrated silica and the dense foam further enhance 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] When the moisturizer is produced, mannitol can be used to keep the whitening tablets at an appropriate hardness to prevent the whitening tablets from being too hardened. The molding agent can be maltodextrin, polyvinyl pyrrolidone, microcrystalline cellulose or polyethylene glycol ~ 150 to maintain the tablet shape of the whitening tablets and maintain homogeneity.

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

[0038] The demoulding agent is magnesium stearate, which facilitates the rapid and intact demoulding of the whitening and cleaning tablets during preparation. The sweeteners are stevioside and trichlorogalactose, which can appropriately increase the sweetness, improve the taste of the whitening and cleaning tablets, and do not cause tooth decay. Sodium benzoate is used as a preservative to prevent bacterial growth and extend the storage period.

[0039] The following is the preferred formula for producing whitening and cleaning 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 except the fragrance and the conditioner are mixed and stirred evenly, and the temperature is lowered to 55-65°C after heating treatment, 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: adding fragrance and conditioner to the granular material, stirring evenly after mixing, and pressing into tablets to obtain the whitening and cleaning tooth tablets.

[0045] In the preparation process of the whitening and cleaning tablets in this scheme, polyethylene glycol ~ 150 and wet granulation are combined. In the preparation process of whitening and cleaning tablets, granulation is first performed, and the other raw materials in the formula except for the fragrance and conditioner are evenly stirred, heated, cooled to 60°C and granulated with a rotary granulator. The granules are spread out on a special tray, placed in a raw material dehumidification room for dehumidification for 15 minutes, and then passed through a vibrating screen after drying. Dehumidification continues until the humidity reaches the standard and is ready for use. Then, the prepared granules are evenly mixed with the fragrance and conditioner, and the whitening and cleaning tablets are obtained by tableting.

[0046] Furthermore, the heating temperature in step S1 is 70-85°C, and the particles are dried at room temperature (usually 25±5°C). The preparation temperature range of the granules is controlled at 70-85°C. Within the above temperature range, the raw materials can be kept stable during the production process. The subsequent drying process can drain the excess water in the whitening and cleaning tablets, and dry them at room temperature. The moisture content of the dried whitening and cleaning tablets is 0.3-3.0%, and the hardness is appropriate.

[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 sieved through a 15-mesh sieve. The sieve allows the particles to pass through with a particle size of 0.9 mm, and the particle size distribution is uniform, which facilitates the mixing of the granules with the conditioner and fragrance, and ensures that the prepared whitening and cleaning tablets have good quality.

[0048] The technical solution of the present invention is 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.

[0066] Methyl mercaptan test results

[0067]

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

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

[0070] 2. Biofilm pre-culture: Take 8 15mL centrifuge tubes, put a HAP sheet in each tube, add 2mL of fresh saliva, cover and place in a 37℃ water bath for 24h. Weigh 0.3g of thioglycollate medium and add 10mL of deionized water to dissolve. Then prepare the breath generation simulation solution according to the 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 them evenly and set aside. Take out the HAP sheets that have been cultured overnight and place them in a 12-well plate, one sheet per well, and randomly group them, with 4 sheets per group. According to the test groups, add the samples to the 12-well plate and let them act for 3 minutes. Take out the HAP sheets, transfer them to the headspace bottle, add 2mL of breath generation simulation liquid, seal them and place them in a 37℃ water bath for 12 hours.

[0072] 4. Determination of methyl mercaptan production: Use gas chromatograph to detect methyl mercaptan in the headspace bottle 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 above table can indicate the degree of deviation of each value in the data set from the mean value of the data set. The larger the standard deviation, the greater the overall dispersion of the data set, and the smaller the standard deviation, the smaller the overall dispersion of the data set. The coefficient of variation is equal to the standard deviation divided by the mean. It is a dimensionless number that can be used to compare the discreteness of populations with significantly different means and eliminate the influence of different units and (or) means on the comparison of the degree of variation of two or more data. When performing statistical analysis, if the coefficient of variation is greater than 15%, it is considered that the data may be abnormal and should be eliminated.

[0075] Results of the test on removal of exogenous stains

[0076]

[0077] Changes in whiteness value ΔL within 30 days

[0078]

[0079]

[0080] Note: The experimental method is:

[0081] 1. Preparation of dental grinding blocks: Cut bovine incisors into enamel blocks of approximately 5 mm × 5 mm × 2 mm in size and embed them in polymethyl methacrylate resin. Grind the enamel labial surface with 180-grit sandpaper moistened with water, and grind the enamel surface of the arc structure flat. Rinse the sample with water, and then grind the enamel surface smooth with 600-grit sandpaper moistened with water. Rinse with 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, take out and rinse with clean water; then immerse it in saturated sodium carbonate solution, stir for 60 seconds, take out and rinse with clean water; finally immerse it in 1% phytic acid solution, stir for 60 seconds, take out and rinse with clean water.

[0083] 3. Preparation of staining solution: First, dissolve gastric mucin with hot water, then add coffee, soy sauce, and black tea, stir evenly, and let it cool. Add FeCl3 solution stored at 4°C before use. The final concentration of each component is: gastric mucin 2.5g / L, coffee 4.0g / L, soy sauce 4.0g / L, black tea 4.0g / L, ferric chloride 0.05g / L.

[0084] 4. Staining of tooth abrasive blocks: Place the acid-etched tooth abrasive blocks in a staining machine for staining for 12 days. Number and mark the stained tooth abrasive blocks, measure the color of tooth enamel (L* before brushing) with a colorimeter, select tooth abrasive blocks with L* values ​​of 30-50, and randomly assign them to the sample group and the control group, 8 blocks in each group, and brush 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 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, and 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, add it to the grinding liquid bottle, fix the grinding liquid bottle on the toothbrush machine, bury the tooth grinding block with the slurry, and brush 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 dry it.

[0087] 7. The brushing conditions for the whiteness value ΔL within 30 days are set as follows: the brushing pressure is 150g±20g; the brushing angle is 0 degrees horizontally; the number of days / frequency of brushing is 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] It can be seen from the test results of Example 1 and Comparative Example 1 that 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. Among them, the tooth cleaning tablet of Comparative Example 1 does not even have a whitening effect after being used for 25 days, and the teeth tend to turn yellow.

[0090] Referring to the test results of the whitening tooth cleaning tablets prepared in Examples 2-4, when the special formula of the present scheme is used in combination with butterfly pea flower extract, the effect of removing bad breath and the degree of whitening of teeth are greatly improved, among which 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 Embodiment 2, except that the whitening agent is replaced by sodium phytate from phthalimide peroxycaproic acid.

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

[0095]

[0096] Results of the test on removal of exogenous stains

[0097]

[0098] Changes in whiteness value ΔL within 30 days

[0099]

[0100] As shown in the test data in the above table, 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 molding agent are changed, as shown in the following table:

[0108] Results of the test on removal of 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, so that 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 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 whitening and cleaning tooth tablets prepared in Example 7 were tested for performance, and the specific test results are shown in the following table:

[0120]

[0121] Results of the test on removal of exogenous stains

[0122]

[0123] Changes in whiteness value ΔL within 30 days

[0124]

[0125] As shown in the test data in the above table, from the test results of Example 2 and Example 7, it can be seen that the addition amount of the butterfly pea flower extract in this scheme is further preferably 0.2-2%. Within this range, the breath freshening effect and the whitening effect on teeth of the whitening tooth cleaning tablets are the best.

[0126] The above embodiments are only preferred implementations of the present invention, and do not limit the patent scope of the present invention.
